Stainless steel square rectangular pipe is a type of hollow strip steel that is widely used for conveying fluids such as oil, natural gas, water, gas, steam, etc. In addition, when the bending and torsional strength are the same, the weight is relatively light, so it is also widely used in the manufacturing of mechanical parts and engineering structures.
