The 5° rotary folded pipes are used to change the direction of the pipeline during installation. One or more long swivel links are assembled until the desired angle change is achieved.

By using swivel links, ideal hydraulic properties are achieved in the pipeline. This helps to ease the complexity of laying and avoid the construction of additional rotary chambers.

When laying pipes, it is necessary to comply with the requirements of DSTU EN 1610:2007 Drains and collectors. Requirements for design and installation (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.
