Classification Of Stainless Steel Pipes And Their Standards

Stainless steel pipes can be divided into many kinds according to different classification methods, so what are the classification methods of stainless steel pipes? What are its criteria? 

Stainless Steel Pipes Classified According To Raw Materials

It is divided into general carbon steel pipe, high-quality carbon structural steel pipe, alloy structural pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe, bimetallic composite pipe, coated and coated pipe to save precious metals and meet special requirements. The variety of stainless steel pipe is complex, the use is different, its technical requirements are different, and the production methods are also different. At that time, the outer diameter of the steel pipe produced was 0.1-4500mm, and the wall thickness was 0.01~250mm. In order to distinguish its characteristics, steel pipes are generally classified according to the following methods.

Stainless Steel Pipes Classified According To Production Methods

Stainless steel pipe according to the production method is divided into seamless pipe and welded pipe two categories, seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe, etc., cold drawing, cold rolled is the secondary processing of steel pipe; Welded pipes are divided into straight seam welded pipes and spiral welded pipes, etc.

Stainless Steel Pipes Are Classified According To The Cross-Sectional Shape

Stainless steel pipes can be divided into round tubes and special-shaped tubes according to the cross-sectional shape. Special-shaped tubes include rectangular tubes, diamond-shaped tubes, elliptical tubes, hexagonal tubes, octogram tubes and various cross-sectional asymmetric tubes. Special-shaped tubes are widely used in various structural parts, things and mechanical parts. Compared with round tubes, special-shaped tubes generally have larger moments of inertia and cross-section modulus, and have greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.

Stainless steel pipes can be divided into equal section tubes and variable section tubes according to the longitudinal section shape. Variable section tubes include conical tubes, stepped tubes and periodic section tubes.

Stainless Steel Pipes Classified According To The Shape Of The Pipe End

Stainless steel pipes can be divided into light pipes and wire tubes (with rebar pipes) according to the condition of the pipe end. Wire pipe can be divided into general wire pipe (transporting water, gas and other low-pressure pipes, using general cylindrical or conical pipe thread connection) and special thread pipe (oil and geological drilling pipes, about important wire pipes, choose special thread connection), for some special pipes, in order to compensate for the influence of threads on the strength of the pipe end, the pipe end is generally thickened (inner thickening, outer thickening or inner and outer thickening) before turning the wire.

Stainless Steel Pipes Classified According To Use

According to the use, it can be divided into oil well pipes (casing, oil pipes and drill pipes, etc.), pipeline pipes, boiler tubes, mechanical structure pipes, hydraulic pillar pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure fertilizer pipes, petroleum cracking pipes) and ship pipes.

Classification of different uses are different, stainless steel pipe has been used in all walks of life, if you want to choose stainless steel pipe, you can choose the right type according to its use, you can also consult the following Kidipipeline online customer service to provide you with reasonable suggestions.
