Stainless Steel square tube is a hollow strip of steel, because the cross section is square so called square tube. A large number of used for conveying fluid pipelines, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength at the same time, lighter weight, so it is also widely used in manufacturing machinery parts and engineering structures.Stainless steel square tube classification: square tube is divided into seamless steel tube and welded steel tube (seam pipe) two categories. 

According to section shape can be divided into square and Rectangular Tube, widely used is circular steel tube, but there are some semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel tube.For stainless steel square tube under fluid pressure to carry out hydraulic test to test its pressure capacity and quality, under the specified pressure does not leak, wet or expansion for qualified, some steel pipe according to the standard or the requirements of the side of the roll test, flaring test, flattening test.

Square tube specifications :5*5~150*150 mm thickness :0.4~ 6.0mmSquare tube material :304, 304L, TP304, TP316L, 316, 316L, 316Ti, 321, 347H, 310S, etc.The production process is: a. Round steel preparation; B. heating; C. Hot rolling perforation; D. cutting head; E. pickling. F. grinding; G. lubrication; H. Cold rolling; I. degreasing; J. Solution heat treatment; K. straightening; L. in cutting; M. pickling. N. Finished product inspection.
