Pipes Sewage

“RTP” pipe of 110, 160 and 200 mm is designed for the outdoor sewerage. The pipes totally conform to the TU 2248-002-78044889-2010 standards.

“RTP” PP-R sewer pipes are applied in the underground sewerage to dispose sewers (the material is resistant to the sewers) and in the telephone conduits as well. In the free-flow medium the PP-R pipes, as well as in the telephone conduits withstand temperature (+95°С) within 5 minutes. At constant temperature (+70°С) the pipe’s service life is 50 years, at +80°С – 25. Besides, the pipes used in the telephone conduits might be in operation at outdoor temperature (-40°С) within 25-30 years.

“RTP” pipes for the outdoor sewerage are adequate to the ring stiffness class SN4 (burial depth – up to 6 meters). The properties and methods of ring stiffness identification have been adopted and approved by DIN EN ISO 9969, European standard.

Rubber wiper seals with a packing block are used as gaskets, which comply with DIN 4060. An installation requires usage of “RTP” special silicone grease.

 

Outdoor sewerage

Outdoor sewerage represents the pipeline network, used for drain disposal from living accommodation and industrial sectors to treatment facilities or waste water storage. The main elements of the sewerage system, both outdoor and sanitary, are the sewage pipes. Among the sewage pipes the most popular are the articles made from polymeric materials, among which the polyvinyl chloride pipes and polypropylene pipes.

Sewage pipes are selected, on the basis of the required characteristics of the concrete pipeline. Articles made from the polymeric materials, including the sewage pipes, have got a number of advantages: overstability at low-density of the material, chemical resistance, resistant to internal wear, ecological safety and durability. Of not little interest of the plastic pipes for outdoor sewerage is their not-too-high price, especially if we compare with their metal analogues.

Operational data for the sewage pipes:

  • temperature ceiling – 60°С;
  • resistance to temperature difference – 0-45°С;

Plumbing in outdoor sewerage is carried out with the pipeline pitch along the drains at a more deeply laying depth, than the depth of ground freezing. If the system is laid in the place of moving of truck transport, the laying depth must be minimum 2 meters
