Transition Coupling

Purpose

Used for flangeless connection of pipelines made of both polyethylene and other dissimilar materials. Can be used in emergency operations.

Technical characteristics

● The coupling is manufactured in accordance with TUU 27.2-33437218.002:2006.

● Axial deviation of pipes on each side ± 6°.

● The coupling body is made of steel grade St3ps, GOST 14637.

● The pressure flange is made of steel grade St3ps, GOST 14637. The axial dimensions of the flange correspond to the typical dimensions of the flange for a working pressure of 10 kg/cm².

● The design of the coupling provides installation in any position.

● The rubber seal is made of rubber grade IRP 1068; rubber mixture grade 5S-3831. The shape of the seal allows for connection to pipes with minor defects on the pipe surface.

● Hexagon nuts are galvanized according to GOST 5915; washers according to GOST 11371; M16 studs are galvanized according to GOST 22034.

● The cold galvanizing method is used, the layer thickness is not less than 9 microns (M16 studs and above (depending on the diameter of the couplings) have a layer thickness of not less than 250 microns). The ends of the studs are protected by plastic caps.

● Type of sealing surfaces of flanges according to GOST 12815, TYPE 1.2 or 3.

● Anti-corrosion coating of couplings according to GOST 9.032, coating class IV minimum 250 microns. The anti-corrosion coating is solid, strong, smooth, without gaps and bubbles and has a strong adhesion to the metal.

Warranty
