1 inch Stainless Welded pipe price per kg

For annealed Stainless Steel pipes with inner diameter above 6.0mm and wall thickness below 13mm, W-B75 Wechls hardness tester can be used. The test is very fast and simple, which is suitable for rapid and nondestructive qualified inspection of stainless steel pipes. The HRB and HRC hardness of stainless steel tubes with inner diameter greater than 30mm and wall thickness greater than 1.2mm are tested by Rockwell hardness tester. For stainless steel tubes with inner diameter greater than 30mm and wall thickness less than 1.2mm, use surface Rockwell hardness tester to test HRT or HRN hardness. For stainless steel pipes with inner diameter less than 0mm and greater than 4.8mm, the hardness of HR15T is tested by Rockwell hardness tester dedicated to pipe. When the inner diameter of the Stainless Steel Pipe is greater than 26mm, Rockwell or surface Rockwell hardness tester can also be used to test the hardness of the inner wall of the pipe.

Stainless steel pipe is a kind of hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural parts. 

In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also used for furniture, kitchenware, etc. 

The hardness of stainless steel pipe is usually measured by Brinell, Rockwell and Vickers. Annealed stainless steel pipe with inner diameter of more than 6.0 mm and wall thickness of less than 13 mm.
