Because the inner and outer walls of precision steel pipe have no oxide layer, bear high pressure and no leakage, high precision, high smoothness, cold bending without deformation, expansion It is mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes or welded pipes. Compared with solid steels such as round steel, seamless steel pipes are lighter in flexural and torsional strength when the bending and torsion strength is the same. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and machinery.

The blanks used for welded steel pipes are steel plates or strip steels. With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of welded steel pipes are increasing, and seamless steel pipes are replaced in more and more fields. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes

Galvanized square pipes are divided into hot-dip galvanized square pipes and cold-galvanized square pipes from the production process. It is precisely because the processing of these two galvanized square tubes is different that they have many different physical and chemical properties. In general, they have many differences in strength, toughness and mechanical properties.
