Sewer pipes and fittings System HT (PPs)

Ostendorf's upgraded pipe system for internal sewerage It fulfills all the requirements of modern internal sewerage systems, from sound insulation and fire protection, up to simplified pipe laying thanks to centimeter markings. exposed to hot water. This is how a high-quality piping system for internal sewerage was created, with the highest
meeting all requirements.

Application of the HT system (PPs) with Ostendorf BS fire collar

The new Ostendorf fire kit is a practical and cost-effective solution for building fire safety. The new generation of Ostendorf BS fire cuffs is distinguished by significantly smaller dimensions and the ability to use them to create a fire seal of pipeline passages through building structures in order to prevent the spread of fire through them in case of fire. In addition, the Ostendorf BS fire sleeve is suitable for all Ostendorf plastic pipes. This property, as well as other remarkable qualities, provides a high level of flexibility for changes in construction projects.
The Ostendorf BS fire collar has been developed and approved for use incl. in soundproof piping systems (Z-19.17-1651). Fire cuff
consists of two halves, so it is possible to install it after laying the pipeline. Thanks to the "zero distance", i.e. the distance between adjacent fire collars can be set to 0, providing maximum design flexibility.

Silence is one of the most valuable blessings for a person. And it is the more precious, the less often we can feel it in ourselves or find it in the world around us. Sewer pipes and fittings Skolan dB
differ precisely in this unusual property - they are not audible.

Nature is an integral part of our life, so it is natural for us to protect it. The sewer system KG (PVC) fully meets the requirements for water resistance, service life and ease of operation. Therefore, it provides reliable protection of the environment from wastewater pollution.

Ostendorf Wells

The Ostendorf manhole system is versatile enough to provide the right solutions to numerous problems in everyday practice. All structural elements are quickly and easily connected to each other and to other pipe systems.
Robust connections and built-in seals guarantee reliable connections in any application. The telescopic tube with cover not only visually harmonizes with the surrounding area. It extends up to 400 mm and is easily adjustable. It is not necessary to determine the exact installation depth. The lid always closes flush with the surface. The telescopic tube always remains mobile and moves along with the soil. This property is especially useful in winter. In addition, the well does not rust.
Thanks to these qualities, the innovative Ostendorf manhole system greatly facilitates the creation of underground sewer networks. Small size with big potential. These are typical inspection wells for external sewage. It is also possible to use it as manholes in parks and squares, in car parks and as drainage wells.

The obvious advantages of Ostendorf polypropylene products compared to PVC sewerage from other manufacturers include the low weight of the products, which gives advantages in the installation and transportation of pipes and sewer fittings. In addition, Ostendorf is an environmentally friendly product: 100% recyclable material for pipes and fittings is possible.

Ostendorf Kunststoffe was founded on 1 May 1973 by the brothers Norbert and Heinrich Ostendorf.

Already in the year of foundation, the production of polymer pipes and fittings made of polypropylene began. In this area, there was a trend of rapid market development, so in a short time the company switched to the production of a complete product program.

In August 2011, Ostendorf opened its own production of sewer pipes and fittings in Russia in the city of Egoryevsk, Moscow Region.

The plant has the latest German technological equipment. Imported raw materials and components are used in production. The quality of products is controlled by German specialists and complies with German standards.

Today Gebr. Ostendorf Kunststoffe GmbH & Co.KG is the leading manufacturer in this market segment. At the same time, sales are carried out through a specialized wholesale trade in sanitary products. The main market for high temperature (HT) products is Germany, but Ostendorf products are also supplied to many countries around the world.

Subsequently, the production of sewer pipes and PVC fittings for outdoor sewerage was expanded. Pipes and fittings are produced with nominal diameters from DN 110 to DN 200. Gebr.
Ostendorf Kunststoff e GmbH & Co. KG has also gained a significant share of the market. Pipes and fittings are manufactured on modern production equipment, some
of them using unique technologies. This ensures economical production with minimal costs.

Technical innovation always comes first at Ostendorf. Thus, after many years of research, the development of a new unusual pipe system appeared.

Silent sewerage system Skolan dB from mineralized polypropylene. Thanks to new developments, Ostendorf has succeeded in minimizing sewer noise in high-rise buildings. The company has developed a special technology for Skolan dB socket connections, which are extremely difficult to form due to the high density of the material.

As the latest product from Gebr. Ostendorf Kunststoff e GmbH & Co. KG can be called a special development KG 2000. This pipe system is characterized primarily by its environmental friendliness. They are used for outdoor sewer lines.

Contrary to the usual product range for outdoor sewage (KG), these products are not made from PVC, but from polypropylene using solid wall pipe technology. A specially designed and patented seal completes this program.

In 2008 Gebr. Ostendorf Kunststoff e GmbH & Co. KG has taken its HT polypropylene pipe system for domestic sewage to an even higher level.
Here, 35 years of experience in the production of polypropylene products has found its embodiment. Products have been created that meet all the requirements of modern piping systems for sound insulation, fire protection and simplified pipe laying with antimeter marking.

All products from Gebr. Ostendorf Kunststoff e GmbH & Co. KG is manufactured and sold in Germany in Vechta. It is subject to constant internal and external quality control.

The company is certified according to DIN EN ISO 9001 and has not only various approvals for use from the German Institute for Building Technology, but also numerous approvals and certificates for other countries for its products.

Most of our population lives in high-rise buildings, the sewerage system of which is assembled from plastic pipes. From the point of view, this is certainly good, but there is also a drawback - a high noise level, when being on the 3rd floor you can clearly hear the noise of sewage rushing down the pipe. Nowadays, special materials and technologies have appeared that can effectively cope with such noise effects.

How is the noise problem solved?

• the use of pipes made of special materials, as well as their connections;
• the use of soundproofing materials;
• use of special fasteners.

Let's consider these options in more detail.

Use of special materials. This implies the use of pipes of increased thickness and special silent connections during the installation of the sewer system. They are made from a special type of polypropylene with mineral additives. It seems to be good, but quite expensive.

The use of soundproofing materials. In this case, during installation, it is possible to wrap the pipes with insulation, while the noise level will significantly decrease. A good solution, less expensive than the one described above, but also not 100% eliminating the noise problem due to residual noise on the fasteners.

Use of special fasteners. This solution is not cheap. It uses special fastening elements, which is not easy to install on your own, it is better to involve professionals for this.

As you can see, the maximum noise reduction effect can be achieved using an integrated approach that combines all of the above points.

How to install a silent sewer

Before installing the sewer system, it is necessary to fulfill the requirements that will ensure the quality functioning of the entire system in the future.

• Preparation of pipes according to the given dimensions - first we measure, then we check, then we cut off;
• we form a groove at the end of the pipe at an angle of up to 150 degrees for ease of installation;
• install the sealing ring;
• make sure that there is no dirt at the joints;
• lubricate the outer part of the pipe with silicone grease or ordinary soap - this greatly facilitates the moment of connection;
• we insert the pipe until it stops, and move it back up to 10 mm - this is necessary to compensate for temperature changes in dimensions;
• shaped parts are inserted without a gap.

• Between the pipe and the wall on which the installation is made, it is necessary to leave a gap of at least four millimeters;
• when installing the riser, clamps are installed every 20 cm.

How are pipes attached and stress relieved?

There are two methods of fixing pipes, rigid and floating.

1. Rigid mount. In this case, the attachment point is a rigid clamp that is attached to the wall and fixes the pipe with a rubber ring.

2. Floating mount. Provides movement of the pipe in the direction along its laying. An important point - you can not fix the mount so that the pipe loses its ability to move.

How to fix the pipe to the wall can be found in the video below.

Became their ability to reduce noise from the flowing liquid. For a long time, this problem was solved by wrapping sewer pipes with porous soundproofing material (for example, polyethylene foam) or mounting a special box around them and densely filling it with mineral wool. Relatively recently, a third way has also appeared to significantly reduce the noise of a liquid flowing in an internal sewer - the use of silent sewer pipes.

POLITEK manufactures pipes and fittings with improved sound absorption for internal sewer systems in accordance with TU 2248-017-52384398-2012 and TU 2248-019-52384398-2012. Outwardly silent pipes and fittings, with the exception of white, do not differ from ordinary polypropylene sewer pipes and fittings for them. White and gray sewer pipes of the same size have almost the same mass; when creating internal sewer systems, they are interchangeable in any ohm combination. The sewer pipes and fittings manufactured by our company, which reduce the noise from the flowing liquid, comply with the requirements of SP 40-102-2000 and SP 40-107-20003.

You can get acquainted with the regulatory documents that determine the permissible noise levels and sound insulation requirements, as well as with other noise protection rules - in.

Advantages of white silent pipes for domestic sewage

The difference between pipes with improved noise attenuation and ordinary ones is in the structure of the material. Silent sewer pipes are made of polypropylene modified with mineral additives. The inclusion of mineral components in the raw material increases the viscosity of the pipe material and leads to a decrease in noise from the liquid to 7–11 dB due to damping (quenching) of sound waves when passing through the pipe wall.

You can learn more about the design features of white pipelines with improved sound absorption, as well as get advice on their installation, at.

You can buy pipes and fittings with improved noise reduction in bulk from the Politek manufacturer at the prices shown on this page. You can order products directly on the website or send a request by mail . Silent pipes for internal sewerage: description, purpose, characteristics, photo, price.

At present, it is difficult to imagine a home in which comfort and tranquility are violated due to rather unpleasant sounds coming from the sewer communications system. Most often, this problem is faced by owners of apartments on the lower floors in apartment buildings who have replaced old cast-iron pipes with new plastic ones. At the moment, there are two solutions to this problem: use silent sewer pipes or treat existing sewer pipes with sound-absorbing material. This solution will save you from unnecessary unpleasant noise, while maintaining comfort and harmony in the house.

Reasons for the spread of additional sounds around the apartment:

• Noise insulation in the pipes is broken by water drains, which pass from above the riser to the sewer communications system.
• Pipes made of plastic and plastic-based alloys are fairly good conductors of sound;
• Unreliable fixation of the riser in a mine or apartment (occurs over time or due to a violation of the installation technology);
• Counter currents of air and water;
• Wide diameter.

The sound that is heard in plastic sewer pipes can be divided into 3 types:

1. Impact sound. Such a sound is caused by unreliable fixation of sewer pipes, which during operation beat against others or against the walls of the mine;
2. Streaming sound. The sound that is heard with oncoming flows of drain water and air;
3. vibration sound- is created due to the resonance of sewer pipes when drains fall, such sounds can also be generated due to a violation of the installation technology of sewer pipes or pipes that need to be replaced due to insufficient fixation in an apartment or a special mine.

Due to the above reasons, annoying household sounds are heard. The problem can be solved quite simply - by replacing the old metal clamps with new ones, but in most cases you will have to do the isolation of the apartment from extraneous noise with your own hands. You will have to use a material that will provide your home with reliable sound insulation.

Loudness Determinants

There are several such factors. For example, the speed at which water flows through pipes. The higher the speed, the more noise is generated. In addition, material plays a significant role. Polymer alloys are often much quieter than conventional plastic pipes. Cast iron pipes have excellent sound insulation and practically do not emit extraneous noise due to their impressive weight. A massive pipe with thick walls will protect your apartment from outside sounds by absorbing the shock wave created by the water drains.

What methods and materials are used to achieve high-quality sound insulation

Do-it-yourself soundproofing of sewer pipes is easier than it seems at first glance. There are various ways:

• Complete sound isolation of a one-piece riser;
• Full redemption of infrasound;
• Use of silent pipes.

The most practical method is the installation of ready-to-use silent pipes. But their price in the building materials market is quite high. Therefore, you can make the sound insulation of sewer pipes with your own hands. For such work, you do not need to purchase expensive equipment, you just need to buy a few rolls of soundproofing material. This material is available as:

• tiles or patches;
• rolls;
• insulation tapes;
• mats.

To start work, you need the presence of insulation material, adhesive tape, several metal clamps with a rubber seal, metal wire or plastic ties of a suitable size and a sharp knife. Quite problematic if your sewer pipes and riser are outside the pipe. In this case, the soundproofing material will spoil the whole appearance. Therefore, experts recommend making a box that needs to be tiled on the outside, which will hide the unseemly appearance, as well as minor defects in the work being done.

The use of modern materials performs several functions simultaneously: sound insulation and heat insulation. An example is soundproofing tape, which is usually sold in rolls. The main advantage of such tapes is the amazing ease of installation. The tape has the shape of a cylinder, so it only needs to be pulled over the required pipe and fixed, this ensures seamless soundproofing. Therefore, it is recommended to take care of sound insulation at the initial stages of replacing sewer pipes in order to avoid the difficulties that arise during the installation of laid sewer communications.

• If the material is purchased in the form of a cylinder, you need to cut it so that it covers the entire area. If the material is purchased in the form of sheets, then measurements should be made so that the sheets overlap each other along the entire diameter;
• When using soundproofing tape, it must be wrapped around the sewer pipe. Moreover, it is necessary to take into account the fact that if during the production of work there are places uncovered with a tape, then the desired effect will not be achieved;
• Material purchased in the form of sheets should be fixed with tape;
• Using a dense sound insulation material, it is recommended to use soft copper wire or plastic ties as fasteners, which are located at a distance of 25-30 centimeters from each other.

Did you know: due to the negative impact on the respiratory system, the use of polyurethane foam or glass wool as a soundproofing material in a residential area is strictly prohibited!

Use of rolled sound-absorbing materials

The order of work should look like this:

• It is necessary to calculate the area to determine the exact amount of insulation material;
• Make a cut in the material so that it envelops the sewer pipe completely;
• The edges of the material should meet end-to-end;
• Sound insulation material should be fixed with copper wire or plastic ties;
• If adhesive tape is used as fastener, then it is necessary to wrap it in several layers for a tighter fit.

Use of polyurethane foam

Extra sounds can be eliminated using polyurethane foam (in the form of a shell). The cross is the most vulnerable spot, so it is she who needs to be covered in a polyurethane shell. Of course, the price of such material is not suitable for everyone, but it pays off with the quality of the material and ease of installation.

In addition, the use of polyurethane foam allows you to process all hard-to-reach places, including crosses and bends. Polyurethane foam is sold, as a rule, in the form of rolls or mats. The use of foam plastic in the form of a shell does not give the same effect as when using polyurethane foam!

Noise isolation by infrasound

Infrasound is sound waves of low frequency. Such a sound is emitted by the sewer riser due to the formation of growths on the inside of the pipe over time. There are several methods of soundproofing by infrasound:

• Replacing the riser - partial or complete;
• Noise suppression artificially.

Partial replacement of the riser is carried out in several stages:

• The middle is sawn off with the help of a grinder, the crosses remain in place;
• Plaque must be removed using aggressive chemicals;
• The plastic pipe must be fixed with transitions;
• If possible, immediately cover the pipe with insulating material.

Use of silent pipes

Silent pipes in their structure are somewhat different from ordinary plastic ones. They have 3 layers, one of which is a layer of sound and heat insulation. 1 layer - polyurethane. This layer prevents corrosion, and small particles of minerals localize noise and are not affected by chemicals. 2 layer - polypropylene.

Blocks the sounds that waste water spreads. 3 layer - polypropylene or polyethylene. Anti-shock layer, it is also immune to high or low temperatures.

• Drawing up a diagram of the proposed work and calculating the required amount of material;
• Pipes must be cut with a hacksaw at an angle of 30 or 150 degrees;
• The edges of the cut fragments must be processed with a file;
• The connection is made with silicone grease;
• It is necessary to take into account the margin - at least 1 centimeter, since under the influence of temperatures the length of the sewer pipe may vary slightly;
• Fasten to the wall with metal clamps with a rubber seal.

Common mistakes made by inexperienced workers:

• Wrong choice of soundproofing material;
• Use of cheap metal clamps without rubber seals;
• A small layer of soundproofing material;
• Insufficient fixation with fasteners, because of this, a sound resonance is formed.

The methods presented above are a visual aid on how to make high-quality sewer sound insulation with your own hands and avoid common mistakes. Good luck!

Silent sewerage: an overview of the ways of competent arrangement and useful tips

No one will argue with the fact that a silent sewer — it is an urgent need, and not just a whim of your heightened hearing. The sound of draining water from a neighboring toilet is not the best accompaniment for any apartment, especially since everything was different before the overhaul. Are you familiar with this?

Why is it making noise

The concept of “quiet” sewerage also arose because today many people in their apartments have plastic - reliable, but at the same time very noisy - risers that do not allow residents of apartments in multi-storey buildings to live in peace. Sewage and water pass through these pipes so clearly that it seems that this water is about to end up right in your apartment.

Why is this happening?

From the point of view of acoustic vibrations, any hollow pipe is an ideal waveguide: constantly reflected from the walls, sound can travel quite long distances with minimal loss of amplitude.

But this is in the pipe, and beyond?

In order for the sound to propagate outside the pipe, which we are actually observing, a combination of two factors is necessary:

1. Pipe weights. It should be insignificant, otherwise the power of the acoustic vibration is simply not enough to make the walls resonate;
2. Strong pipe walls. In plastic, everything is in order with this - both high density and solidity of the structure.

Relatively recently, this problem was not relevant at all due to the fact that all pipelines in multi-storey buildings were made of cast iron, which made all sounds and processes inside these pipes inaudible.

Despite the excellent sound insulation of cast iron systems, this factor is their only advantage today.

The fact is that there are many reasons why users prefer plastic pipes. Let's look at the properties of two similar materials, identify all their advantages and disadvantages.

From all of the above, we can draw an unambiguous conclusion - a PVC pipe system has more advantages, and therefore more expedient than cast iron pipes.

But, as in any other case, not everything is as smooth as we would like, and one cannot do without minuses. In this case, the disadvantage of plastic pipes is the lack of sound insulation, which makes their operation not very convenient.

Let's take a closer look at how such a small but significant minus can be eliminated with your own hands and at no extra cost. Let's start with an overview of each of the available methods.

How to create silence

We will not beat around the bush, we will immediately analyze the popular and current options for creating silence in the bathroom. As an example, consider:

1. construction of a completely new sewerage system;
2. reconstruction of an existing system.

Zero installation

So, we imagine a situation where there is no riser in the house at all and you need to decide on the choice of material, on which the silent operation of the system itself will depend. The best option in this case are silent sewer pipes.

There is nothing complicated in their design, these are all the same plastic pipes, they are simply made in three layers. The outer layer, like the inner one, is made of a material standard for such pipes - PVC or polypropylene, but the middle layer is made of a material with the addition of mineral filler.

The presented product really suppresses sound noise, but it is impossible to say with certainty about one hundred percent effectiveness after its purchase and installation.
Quite a few factors affect the criterion under consideration: the material of the walls of the bathroom, the number of turns in the sewerage system, etc.
When soundproofing sewers, try to take into account all the factors affecting the noise level in order to maximize the figure in question.

Who's who in the market

Generally speaking, then, of course, the material in question seems to be a ready-made solution, but its price may scare the consumer a little, because it cannot be called low.

How much do such solutions cost? Everyone is different...

So the Italian Redi Phonoline system is the most cost-effective in terms of technical characteristics and cost, and has also proven itself in the construction of stadiums for the World Cup in 2018 and has the Best office awards in the nomination "Acoustic comfort of premises"

The most well-known brand of silent pipes is Skolan dB from Ostendorf. According to him, you will sleep in an apartment with silent sewer systems installed as a baby's dream.

What is the asking price? Let's look at retail prices:

As you can see, having collected all the sewage from the silent elements of this manufacturer, its cost will be quite large in comparison with conventional PVC pipes.

What about other manufacturers?

REHAU is another well-known manufacturer of plastic pipes that offers its own option for arranging a silent sewer system.

According to the manufacturer, sealing rings (rubber seals) for fittings and pipes of the Rehau Raupiano series are made of styrene-butadiene rubber with a hardness of 60 Shore.

How much will such an innovation cost customers?

As you can see, the cost of innovation is prohibitive. For example, consider the products of another well-known manufacturer - WAVIN and its ASTO series.

The internal sewerage from WAVIN received its name Asto due to the material astolan (ASTOLAN) used in the production of elements. This is polypropylene modified with mineral additives having a fiber structure, increasing the density to 1.9 g/cm3.

All this is good, but what about the prices?

As you can see, this manufacturer's price is not at all democratic. However, like the other two, whose silent systems we considered. But this is not the end of the noise solution - the system has yet to be correctly installed.

How to properly mount

Having purchased such expensive products, when installing the sewer system, you should follow the manufacturer's recommendations as closely as possible. In most cases they are the same:

1. When planning the sewer system, try to avoid a large number of turns. The number of such bends will determine the resistance that the fluid passing through the system will encounter. The strength of the noise will also depend on this criterion;
2. It is not worth saving in such a matter, it will not lead to anything good. When buying pipes, purchase bends, tees and couplings of the same series;
3. If the current regulations require the installation of a large diameter pipe, do not neglect them and replace them with a small diameter. It must be understood that the smaller the pipe, the greater the pressure, and the noise from strong pressure will be greater.

It is best to lay silent sewer pipes in a separate isolated space - a specially constructed box.
This will make it possible to minimize the noise in the house or in the apartment.
Considering all the above recommendations, you can achieve maximum sound insulation.

Reconstruction of the old system

As is often the case, first we do it, then we redo it. So it is with the sewerage - for example, there is already a plastic riser, and the pipes in the system are also already mounted from PVC. But there was a noise that irritated all households ....

So, we are faced with the task of soundproofing the already existing sewage system from PVC pipes as efficiently as possible.

A banal example, you say? You can just sew up the pipes with drywall ...

I must say right away that the noise problem will not radically disappear, and I will offer the following solution:

1. If the pipes are located in a niche, it is necessary to wrap them with material, preferably dense, capable of damping sound vibrations.

If you want to save money, and, as an option, consider old things as insulating material: jackets, blankets, etc., be prepared for the fact that if the pipes leak, then instead of soundproofing you will get an even larger problem.

1. After the work done, it is necessary to close the niche with a lid. Here you can use plywood, boards or sheets of other material. It must be understood that the level of sound insulation will depend on the thickness of the skin. The thicker the material, the better the insulation.

The following presented method is technically more difficult, but its efficiency is higher.

The step by step instructions are:

1. First of all, it is necessary to soundproof the exit and entrance of the highway through the floors and interfloor. To carry out this process, it is necessary to calculate the free space around the pipes, and in places where they pass through concrete or brick:
   • After that, you can pick up a rubber cuff of the desired diameter;

• • If this is not possible, then you can blow out this space with mounting foam;

1. After the work done, it is necessary to proceed to the next stage - the soundproofing fastening of the pipes. It is necessary to make sure that the structure is firmly fixed and does not “walk” from one side to the other during the passage of water flows through the pipes. Here, special clamps and fasteners will be excellent helpers, inside of which there will be rubber gaskets;

Acquisition of sound vibration fasteners is optional.
Therefore, many refuse these parts, because their price is really rather big.
But with their help it will be possible to reduce the noise level as much as possible.
Even conventional fasteners with foam rubber gaskets can reduce vibration levels.

1. The third stage in the process under consideration is the installation of a special soundproof shell, as well as closing the entire structure with a lid. It is not difficult to make a box; sheets or wooden panels are suitable for such purposes. If you sheathe the main sheets with polystyrene foam, the effect will be maximum.

Despite the apparent fragility of this material, it shows good results. Such material is made of expanded polystyrene or polystyrene and has a tongue-and-groove connection. Due to this, such a shell is very easy to put on a pipe of any diameter.

To fix it, it must be wrapped with tape or plastic clamps. The advantage of this soundproofing technology is the ease of installation.

Captain Evidence informs: the gap between the pipe and the wall does not always allow the installation of such a shell, since its thickness ranges from 30 to 100 mm.
If this is your case, then you can purchase a soundproof flexible sheet and use it to wrap the pipe, fixing the entire structure with clamps.

In principle, all the main methods were presented above, so it's time to draw conclusions.

Completion

As you can see, the construction of a silent sewer has 2 solutions. It can be made both from purchased silent elements, and equipped with your own hands from auxiliary ones. It is best to build a sewer system from scratch, and it is easier and more efficient.
