Scope

Swivel seam pipes plast with a rotation angle of 5 ° are used to change the direction of the pipeline when laying. One or more long rotary links are assembled until the desired angular change is achieved. Using long rotary links, ideal hydraulic properties in the pipeline are reached. This makes it easier to lay and avoids the construction of additional rotary chambers.

Plast pipes are reinforced concrete pressureless pipes with protective shells made of polyethylene. The protective sheath is made of low pressure polyethylene (LDPE) according to GOST 16338-85, designed to ensure durability (at least 50 years) and waterproofing of sewer pipes during operation in conditions of action inside the pipes of highly aggressive environment to concrete (reinforced concrete). PNT is resistant to concentrated hydrochloric, carboxylic and fusible acids, oils, fats, alkalis, salt solutions, resistant to gasoline, low temperatures, ductile and has good impact resistance.

The requirements of DSTU EN 1610: 2007 Drains and collectors must be observed when laying pipes. Construction and installation requirements (EN 1610: 1997, IDT).
