Manufacturer of Tubes GOST 9941−81 in India

Tubes GOST 9941−81 products are made with carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and titanium. The 17% chromium, 9% nickel and 2% manganese provide the material with high mechanical properties. The GOST 9941-81 Seamless Cold and Warm-deformed Tube are made through cold drawing process and can have minimum yield strength of 216 MPa and minimum tensile strength of 549 MPa with 35% minimum elongation at break. The diameter of the tubes and pipes range up to 95mm and above. The tolerances of the GOST 9941-81 Warm-deformed Tubes depend on the outer diameter ranges of up to 5mm, 10mm, 30mm and over 95mm.

The wall thickness of the pipes range from 0.2mm to over 7mm. The tolerances of the wall thicknesses also range differently. The length of the GOST 9941-82 pipe can be single random, double random or custom cut to length ranging from 5800mm to 18000mm. The pipes and tubes can be applied on high corrosive and high temperature applications. There are U tubes which are specifically made for the heat exchanger applications. The DIN 1.4541 ERW Pipe is made through electric resistance weld and can be welded with any other pipe products without the need for filler materials, preheating or any post weld heat treatment methods.
