Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion 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 often used as furniture and kitchen utensils.

Stainless steel pipes are divided into seamless pipes and welded pipes according to the production method. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled are the secondary types of steel pipes. Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.

Round tube material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S

Stainless steel square pipe classification: square pipes are divided into two categories: seamless steel pipes and welded steel pipes (seam pipes). According to the cross-sectional shape, it can be divided into square and rectangular pipes. Round steel pipes and square pipes are widely used, but Jiangsu Hangdong also supplys some other steel pipes with special shapes such as semicircle, hexagon, equilateral triangle and octagon pipes.

For stainless steel square pipes subjected to fluid pressure, hydraulic tests must be carried out to verify their pressure resistance and quality, leakage, wetting or expansion under the specified pressure to see whether they are qualified or not. Some steel pipes must be oiled according to the standard or as per buys' requirements.

Square tube specifications: 5*5~150*150 mm Thickness: 0.4~6.0 mm
Square tube material: 304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S
