Swivel 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).

Marking:

Tig is a cylindrical seam pipe with an integrated sealing ring.

Tg – cylindrical seam pipe with a stepped surface of the sleeve end and sealing with a free wedge-shaped rubber sealing ring.

The first group of digits indicates the diameter of the nominal passage in mm, the second – the useful length in mm, for example, Tg-800×2400 DSTU EN 1916 – a seamless pipe with an integrated rubber seal with a diameter of 800 mm and a length of 2400 mm.

Abig – seamless pipes with integrated rubber sealing ring.

Abg – seamless pipes with a free rubber sealing ring.

The prefix “bend” (Abig Tig-800×900-bend DSTU EN 1916) means that the pipe is rotatable.

Plast pipes are labeled with an additional postfix “P”. For example, Abig Plast Tig-1000×2400-b-P DSTU EN 1916
