Stainless Steel Square Tube

Stainless Steel Square Tube

Stainless steel flat tube is a kind of stainless steel tube, it is mostly used to transport natural gas, coal gas,oil,water,steam and so on. Whats more, they are light when the flexural strength and torsion strength are the same,so it is also widely used in the manufacture of mechanical parts and engineering structures.
