Sewer pipes made ​​of polypropylene .standards

Scope of polypropylene pipes

for the production of polypropylene products using various technologies.Polypropylene tubes are made from a blend of polypropylene copolymer with various inorganic and organic panels.

main scope of polypropylene pipes is laying domestic sewage, as this material has a relatively low hardness and poor withstand the pressure created when an underground sewage arrangement.However, in the middle of the premises of PP pipe materials have a number of advantages:

• viscosity of polypropylene to withstand mechanical stress without failure;
• no sensitivity to chemically aggressive media such as acid and alkali;
• a large temperature range for long-term work - from minus 50 ° C to plus 90 ° C;
• durability, guaranteed service life is 50 years;
• low weight;
• smooth internal surfaces of pipes for sewerage.

Polypropylene is absolutely not harmful to human health and the environment and may well be used for domestic purposes.

GOST on polypropylene pipes for sewerage

TU 4926-002-88742502-00 apply to sewerage polypropylene pipes and fittings, which can be used for the organization of domestic sewage with the highest temperature of 75 ° C fluid.Within 1 minute, according to GOST such pipes can withstand a temperature of 95 ° C.product marking consists of the letter designation product names, and capital letters indicate the figures relating to the funnel, and the lower case - to the smooth end of the pipe.Also mark indicates the outer diameter polypropylene sewer pipe, and the size of the shaped profile.All the requirements of GOST transportation, storage and safe use must be followed by manufacturers of polypropylene sewer pipes in strict order.

Installation sewerage polypropylene

Installing sewer system made of PP pipes does not require much effort and bringing special equipment.Reliable and easy connection of parts of the system is ensured by the presence on the spigot ends of the pipe structure.Rubber O-rings which are in the socket ensures tightness of the structure.Sizes diameter polypropylene pipes allows to use them for internal drainage in the room without any extra cost on couplings and fittings.

In the absence of bells at the ends of polypropylene sewer pipes, their joints carry a soldering iron or welding machine.On the technology of these works, see the article "Welding of polypropylene pipes."

Transport and storage PP pipes according to GOST

According to TU 4926-002-88742502-00:

• Polypropylene pipes and fittings can be transported by any means suitable for the purpose of transport;
• Storage polypropylene products should be carried out in unheated warehouses without direct sunlight.If heaters are used, the distance to the polypropylene pipes must be greater than 1 m;
• height of stacked pipes should not be more than 1.5 m;
• transport temperature - above -10 ° C.

If you follow uncomplicated rules of operation polypropylene sewers, it will run smoothly for many decades.
