Stainless steel pipe is a sort of hole strip of steel, in the enterprise for a giant wide variety of fluid pipeline, such as oil, gas, water, gas, steam, etc., in addition, bending, torsional energy at the same time, mild weight, so it is also broadly used in the manufacture of mechanical parts and engineering structures.
1, the classification of stainless steel pipe: steel pipe seamless steel pipe and welded steel pipe (welded pipe) two categories. Seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extrusion pipe, etc., cold drawn, cold rolled steel pipe is the secondary processing; Welded pipe is divided into straight seam welded pipe and spiral welded pipe. According to the shape of the section can be divided into round pipe and special-shaped pipe, broadly used is round metal pipe, but there are also some square, rectangular, semicircle, hexagonal, equilateral triangle, octagonal special-shaped steel pipe.
2, for the steel pipe subjected to fluid stress to elevate out hydraulic assessments to check its strain capacity and quality, beneath the detailed stress does now not produce leakage, wetting or growth for qualified, some metal pipe in accordance to the popular or the request of the demand for side rolling test, floor increasing test, pulling down test, etc.
