Definition and Specifications
Definition: Thick-walled stainless steel seamless pipe is a stainless steel pipe with a relatively high wall thickness. It is made of steel ingots or solid tubes through perforation into rough tubes, and then made through hot rolling, cold rolling or cold drawing. It has no seams around it and is a type of stainless steel pipe.
Specification range: The outer diameter of large-diameter thick-walled stainless steel seamless pipes is usually more than 325mm, and the wall thickness is more than 20mm. Currently, the single weld diameter can reach 1220mm, the wall thickness can reach 80mm, and the double weld diameter can reach 2020mm.
What are the characteristics of thick-walled stainless steel seamless pipes?
