Sphere of application of polypropylene pipes
Various technologies are used for the production of polypropylene products. Polypropylene pipes are made from a mixture of a copolymer of polypropylene with various mineral and organic inserts.
The main field of application of polypropylene pipes is the laying of internal sewage, since this material has a relatively small hardness and does not withstand the pressure created by underground sewerage. However, in the middle of the premises, PP pipes have a number of advantages:
- , the viscosity of polypropylene allows it to withstand mechanical stress without destroying it;
- is not sensitive to chemically aggressive media, such as alkali and acid;
- large temperature range for long-term operation - from minus 50 ° C to plus 90 ° C;
- durability, guaranteed life is 50 years;
- light weight;
- smoothness of the internal surfaces of pipes for sewerage.
Polypropylene is absolutely not harmful to human health and the environment and can be used for household purposes.
GOST for polypropylene pipes for sewerage
TU 4926-002-88742502-00 apply to sewer polypropylene pipes and their shaped elements that can be used for the organization of internal sewerage with the highest liquid temperature of 75 ° C.Within 1 minute, according to GOST, such pipes can withstand temperatures of 95 ° C.The product marking consists of the letter designation of the product name, with capital letters indicating the indicators relating to the bell, and the lower case letters indicate the smooth end of the pipe. Also in the mark indicate the outside diameter of the polypropylene sewer pipe, as well as the dimensions of the profile. All requirements of GOST for transportation, storage and safe use should be observed by manufacturers of polypropylene sewer pipes in strict order.
Installation of sewerage from polypropylene
Installation of a sewage system from PP pipes does not require special efforts and attraction of special equipment. Reliable and easy connection of parts of the system is ensured by the presence of bell-shaped structures at the pipe ends. Rubber sealing rings, located in the funnels ensure the tightness of the structure. The size range of diameters of polypropylene pipes allows them to be used for internal drainage in a room without unnecessary costs for couplings and fittings.
If there are no sockets at the ends of polypropylene sewer pipes, they are connected by a soldering iron or welding machine. On the technology of these works, read the article "Welding of polypropylene pipes".
Transport and storage of PP pipes according to GOST
According to TU 4926-002-88742502-00:
- Polypropylene pipes and their shaped elements can be transported by any suitable transport mode;
- Polypropylene products should be stored in unheated warehouses without direct sunlight. If heating appliances are used, the distance to polypropylene pipes should exceed 1m;
- The height of stacked pipes should not be more than 1.5 m;
- Transport temperature - above minus 10 ° C.
If you follow the simple rules of operation of polypropylene sewerage, then it will run smoothly for many decades.
