Stainless steel pipe
is a hollow elongated round steel material, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchen utensils.
According to the material, 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, and bimetallic composite pipes, coating and coating pipes to save precious metals and meet special requirements. . There are many kinds of stainless steel pipes with different uses, their technical requirements are different, and their production methods are also different. Currently produced steel pipes have an outer diameter ranging from 0.1 to 4500mm and a wall thickness ranging from 0.01 to 250mm.
According to the production method, stainless steel pipes are divided into two categories: seamless pipes and welded pipes. Seamless Tubes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Processing; welded pipes are divided into straight seam welded pipes and spiral welded pipes.
