304316 Square Steel Tube 316l Rectangular Steel Tube

Introduction: Stainless Steel Rectangular Tube is a hollow strip of steel, because the cross-section is a square so-called square tube. A large number of pipes are used for conveying fluids, such as oil, natural gas, water, gas, steam, etc..In addition, when bending and torsion strength are the same, the weight is lighter, so they are also widely used in manufacturing mechanical parts and engineering structures. The stainless steel square pipe subjected to fluid pressure shall be subjected to a hydraulic test to check its pressure resistance and quality. No leakage, wetting or expansion shall occur under the specified pressure, some steel pipe also according to the requirements of the standard or demand side edge test, expanding test, flattening test, and so on.
