Definition of stainless steel pipe

Stainless steel round pipe is a hollow long round steel, the equivalent stainless steel square pipe is a hollow long square steel.

Production difference:

Stainless steel round pipe is made of stainless steel strip extruded into a round shape and then welded online. Stainless steel square pipes are first made into stainless steel round pipes, and then extruded into square pipes through moulds.

Difference in inner wall process:

The outer wall of stainless steel round pipe is mostly polished, while stainless steel square pipe is brushed.

Difference in pipe mouth process:

Stainless steel round pipe can be processed such as shrinkage, flaring, taper, reducer, crimping, chauffeuring, etc., while the stainless steel square pipe can not be processed.

Difference in structural stress:

Stainless steel round pipe surface force is more uniform; Stainless steel square pipe has four 90-degree angles, not easy to rotate and twist, more solid when fixing certain objects.

Difference in use:

In many cases, the bottom pipe and elbow are interchangeable, but in some cases they are not. Stainless steel round pipes have become the preferred choice for fluid transfer due to the use of stainless steel round pipe construction and the use of a polishing process on the inside, resulting in an interior that is not prone to scale build-up and is easy to clean. Stainless steel Square pipe is easy to accumulate scale inside and is not easy to clean, so it is generally not used for fluid conveying. Because the resisting moment of stainless steel square pipe is larger than that of stainless steel round pipe, it will be stronger, so when it is used as a structural support, stainless steel square pipe will be chosen as the main component.

Application of stainless steel pipe:

Stainless steel pipe is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transport pipelines as well as mechanical structural components. In addition, when the bending and torsion strength is the same, it is lighter in weight, so it is also widely used in the manufacture of mechanical parts and engineering structures. Of course, it is also commonly used for furniture and kitchenware.
