Product Description

321 Polished Finish Hollow Stainless Steel Square Pipe / Tube 80X80X3mm
 
Stainless steel square pipe is a hollow strip of steel, because the section is square, so it is called square pipe. A large number of pipelines are used to transport fluids, such as petroleum, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used to manufacture mechanical parts and engineering structures.
