How are stainless steel pipes classified?
Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, as well as bimetallic composite pipes, coated and coated pipes to save precious metals and meet special requirements. There are various types and uses of stainless steel pipes, with varying technical requirements and production methods. The current production of steel pipes has an outer diameter range of 0.1-450mm and a wall thickness range of 0.01-250mm. To distinguish its characteristics, steel pipes are usually classified according to the following method.
