ASTM A321 201 304 316 Stainless Welded pipe

Stainless Steel has been used for more than 70 years as a structural material for the construction of new buildings and the restoration of historic sites. Early designs were calculated according to basic principles. Today, design codes, such as the American Society of Civil Engineers' ANSI/ASCE-8-90" Design Code for Cold-Formed Stainless Steel Structures "and the" Design Manual for Structural Stainless Steel "published by NiDI in collaboration with Euro Inox, simplify the design of long-life, good-quality building structures.

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. Production process of Stainless Steel Seamless Pipe A. round steel preparation; b. Heating; c. Hot rolling perforation; d. Cutting head; e. Pickling; f. Grinding; g. Lubrication; h. Cold rolling; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Pipe cutting; m. Pickling; n. Finished product inspection. Common materials are 201, 304 and 316.ETC
