We promise to accept any third-party testing. The sinosure factory is not afraid of any inspection. Welcome to make appointment to visit the factory.
Stainless steel welded pipe is a kind of hollow long circular steel material. It is mainly widely used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures.
Pipes for petroleum, chemical, medical, food, light industry, mechanical instrumentation, and other industrial pipelines and mechanical structural parts are widely used as stainless steel welds.
In addition, when the bending and torsion strength are the same, the weight is lighter, which is also widely used in manufacturing mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils.
