Stainless Tube Classification
Jun 25, 2018

Seamless steel pipe and welded steel pipe (seamed pipe) two broad categories. According to the shape of the cross-section can be divided into round tubes and shaped tubes, widely used round steel tube, but there are also some square, rectangular, semi-circular, hexagonal, equilateral triangle, octagonal and other special-shaped steel.


For steel pipes subject to fluid pressure, hydraulic tests are required to test their pressure resistance and quality. No leaks, soaks, or expansions are acceptable under specified pressures. Some steel pipes are also subjected to crimping tests according to standards or demand-side requirements. , flaring tests, flattening tests, etc.


Seamless stainless steel tube also called stainless steel seamless


Round bar refers to solid bar steel with a circular section. Its specifications are expressed in millimeters of diameter. For example, "50" means a round steel with a diameter of 50 mm.


Round steel is divided into hot-rolled, forged and cold-drawn three. The specifications of the hot-rolled round steel are 5.5-250 mm. Among them: 5.5-25mm small round steel is mostly supplied in bundles of straight strips, often used as reinforcement, bolts and various mechanical parts; round steel larger than 25mm is mainly used for manufacturing mechanical parts or as seamless steel tube blanks.


45# round steel is divided into hot rolling, forging and cold drawing three kinds. The specifications of the hot-rolled round steel are 5.5-250 mm. Among them: 5.5-25 mm small round steel mostly straight
