Without sewer systems today it is impossible to imagine civil and industrial construction. Such constructions are intended for water disposal and removal of the liquid and solid components of human activity, as well as for waste treatment before returning to the environment.
What materials are used
Modern sewer systems are constantly developing. Today on sale you can find the Ostendorf sewage system, which is manufactured in Germany and is designed to equip external and internal silent sewers. Pipes at the core of the system can be made of different materials, namely from:
- mineralized polypropylene;
- PVC
- polypropylene.
Main types and characteristics
For the arrangement of storm and external gravity drainage systems are used marked with KG. They are made of NPHV pipes, and their distinctive features are ease of installation and dismantling, as well as low weight. The internal parts of the pipes have a smooth surface, excellent resistance to corrosion, are resistant to aggressive substances, are well able to cope with the effects of different temperatures and environments passing through the pipes. Liquid temperature can reach + 60 ˚. Such products can be distinguished by orange-brown color. They have the following lengths: 50, 100, 200 and 500 cm. The diameter varies from 100 to 200 mm.
Ostendorf Sewerage may be represented by products marked HT. The letters indicate pipes and fittings that are used in domestic sewers. Such products are resistant to chemical and thermal effects, are made of flame-retardant propylene. The length can vary from 15 to 500 cm, while the diameter is equal to the limit from 32 to 150 mm. The pipes have an internal seal and are gray. They are able to work at elevated temperatures up to + 90 ˚. The system is easy to install, has an optimal cost, and therefore is popular in Russia.
The Ostendorf sewage system is also offered for sale in the Skolan dB variety. These systems are for indoor installation. They are fireproof, durable and noiseless. With their help, you can create increased comfort in offices and homes. The fluid moves through the pipes completely silently. The noise level is 15 decibels. During the installation, clamps are used that absorb sounds. If the installation is carried out without them, the noise level will be 21 dB. All elements are made of mineralized polypropylene and have a light gray color.
Description of external sewage
The Ostendorf sewage system may also be external. For this, pipes from PVC KG and KG 2000 are used. These products are designed for long-term operation. They were tested under pressure in 3 atmospheres. Such a system can be laid next to pipes used for drinking water. This suggests that the elements do an excellent job with the operation, in which increased requirements are spelled out. If the pipes in front of you are green, this means that they are made of mineralized polypropylene and must be marked KG 2000.
Why choose Ostendorf: customer reviews of products
After reading the reviews about the Ostendorf sewage system, you can understand that these systems have many advantages. According to customers, the pipes have high reliability and durability. They can be operated for 100 years. The base material is durable. Products are resistant to high temperatures, aggressive environments that may be present in the effluent.
Systems are made from environmentally friendly substances. According to customers, the silent Ostendorf sewage system can be laid in high-rise buildings. After all, it is characterized by comfortable operation. Pipes are lightweight, which also simplifies their transportation. The walls, as buyers emphasize, are smooth. This eliminates the delay of calcareous deposits, bacterial colonies and the occurrence of fungus. Products are inexpensive. This allows you to use them in the construction of socially significant objects.
Key Features Reviews
The Ostendorf domestic sewage system has one important feature, which is the use of generalized propylene in the production process. It has a dense structure, which distinguishes it from analogues. Couplings and pipes were designed to replace the cast iron counterpart. If we compare the Skolan dB system, we can note that it is unique. Buyers emphasize that it is technically similar to a cast-iron system, but has improved polymer pipe parameters. As one of the main differences, the properties of noise absorption should be highlighted. Products have thick walls and have a high density.
There are mineral additives in the material that contribute to the absorption of noise. For installation there is no need to use special devices, there will be enough clamps. This distinguishes Skolan dB from thin-walled counterparts. The Ostendorf outdoor sewage system has rather thick walls, which exclude damage at the time of mechanical cleaning from mud deposits. If we take the 110 mm pipe as an example, the wall thickness in this case will be 5.3 mm.
Consumers like the assortment of clamps of a special design. They are necessary for rigid safety fastening of caps in those places where cleaning will be carried out. This fixation eliminates pop-up plugs at high pressure.
Cost of sewage systems in Gomel
The Ostendorf sewage system in Gomel can be purchased in a wide range. For example, a polypropylene pipe for domestic sewage will cost 0.68 bel. rub. for a product with the following parameters: 32 x 150 cm. A fitting for internal sewage can be bought for 1.64 bel. rub. Compensation pipe with a diameter of 50 cm will cost 3 bel. rub. The Ostendorf storm sewer in Gomel can also be found. An example is a pipe, the price of which is 10.68 bel. rub. The wall thickness is 3.4 mm. Overall dimensions are 110 x 500 mm.
Reviews about the installation process
Before connecting pipes, ends and sockets, it should be cleaned of dirt and burrs. Apply factory grease to the mowed part. The pipe must be placed in the bell to form a single axis. After that, it is advanced 10 mm. Consumers are advised to worry about reliable and complete fixation. For this, fastening is carried out with clamps.
To compensate for the stress, rubber gaskets should be placed in the pipes. Home masters emphasize that it is important to ensure the longitudinal mobility of the system. To do this, the clamps should not be fully tightened. Pipes to which several elements are connected are fixed rigidly along the entire length. At the same time, conditions should be created for the linear expansion of fittings.
What is important to know about the area of use
You can request a certificate for sewage "Ostendorf" from the seller. But this is not all that should be known for the successful operation of such systems. Polypropylene pipes are more often used for laying internal systems, since this material does not cope well with soil pressure without additional protection.
External sewage is usually laid underground. Internal systems exclude compression, therefore polypropylene pipes are much more preferable for this from pipes from other materials. This is due to the excellent material properties. It is resistant to deformation, shock and contact with chemicals. The material is heat-resistant and is able to withstand temperatures up to 95 ° C, while PVC - only up to 60 ° C.
Polypropylene pipes are also used for laying external systems. However, polyvinyl chloride pipes are usually used for this. For external sewage, polypropylene products are double-layer. They have a smooth inner and corrugated outer surface. Such a pipe is able to withstand different loads and can pass large volumes of effluent due to the smoothness of the inner walls. Polypropylene pipes for the installation of internal sewers are light gray in color, while pipes for external systems usually have an orange-brown hue.
Finally
Polypropylene sewage is easy to install. Its installation can be carried out without additional devices, only manually. Polypropylene products are interconnected thanks to a profiled inner rubber ring. Its protrusions facilitate the passage of the pipe inward, but prevent exit.
When purchasing pipes for internal sewerage from the manufacturer "Ostendorf", you should pay attention to the marking. It should include two letters - NT. Such products are characterized by chemical and thermal stability, due to the fact that they are made of flame-resistant materials. Such pipes for domestic sewage are manufactured in Germany, which means that it meets all the necessary standards and requirements in terms of sound insulation and fire protection. Such products are centimeter marked, which simplifies the installation process.
