Tees

The plant has capacities for the production of seamless and welded tees in a wide range of sizes and reference documents.

Hydroformed seamless tees of diameters 57 to 325 mm can be made

from carbon steel under DSTU GOST 17376-2003 (make 2);

from corrosion-resisting steel under DSTU EN 10253-4:2016.

Welded tees are fabricated with diameters of 426 to 1440 mm using manual argon-arc, semi-automatic and automated welding with physical weld inspection (VM, DP, US and RG). Welded tees are made from
