What is the classification of stainless steel round pipe?
This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (welded pipe) two categories.
According to the different manufacturing process can be: hot rolling, extrusion, cold drawing and cold rolling these basic types, according to the section shape can be divided into round pipe and shaped pipe, widely used is round steel pipe, but there are also some square, rectangular, semicircular, hexagonal, equilateral triangle, octagonal and other shaped stainless steel pipe.
For the steel pipe under fluid pressure to carry out hydraulic tests to test its pressure resistance and quality, under the specified pressure does not leak, wet or expansion qualified, some steel pipe also according to the standard or the requirements of the demander flange test, flaring test, flattening test.
Seamless stainless steel round pipe, also known as stainless steel seamless pipe, is made of steel ingot or solid tube blank perforated into a tube, and then made of hot rolled, cold rolled or cold drawn. The specifications of the seamless steel pipe are expressed by the outer diameter * the wall thickness of millimeters.
