Stainless steel pipes by material into ordinary carbon steel pipe, high quality carbon structural steel, alloy structural steel tube, alloy tube, bearing steel tube, stainless steel pipe, and to save precious metals and to meet the special requirements of the metal pipe, coating and coated tubes. A wide variety of stainless steel pipe, different uses, different technical requirements, production methods are also different. The current production range of wall thickness of the pipe outside diameter range 0.1-4500mm, 0.01~250mm. In order to differentiate its characteristics, usually classify the pipe in the following ways.


Stainless steel seamless tube and pipe two categories divided according to production, can be divided into hot-rolled seamless steel pipe pipe, cold rolling mill, cold drawn tubes and extruded tubes, cold drawing, cold rolled steel pipe of the secondary processing pipe, straight seam welded pipe and spiral welded pipe and so on.
Classified according to the cross-sectional shape tubes of stainless steel tubes and shaped tubes. Special-shaped tube rectangular tube, diamond pipe, oval tubes, hexagonal tubes, all tubes and a variety of asymmetric section tubes. Special-shaped tube is widely used for a variety of structural parts, tools and machine parts. Compared with the round tube, shaped tube generally has a larger moment of inertia and section modulus, flexural, torsional capacity larger, you can greatly reduce the structural weight, steel.

Stainless steel pipe by vertical shapes can be divided into sections such as tubes and tapered tube. Variable cross-section tube with conical tube, step tubes, and die-rolled section tubes.
Tube caps
Stainless steel tubes according to the pipe end can be divided into the light pipe and threading pipes (threaded steel pipe). Car silk tube and can is divided into general car silk tube (conveying water, and gas, low voltage with tube, used General cylindrical or Cone tube thread connection) and special thread tube (oil, and geological drilling with tube, for important of car silk tube, used special thread connection), on some special with tube, for make up thread on tube end strength of effect, usually in car silk Qian first for tube end thickened (within thickened, and outside thickened or both inside and outside thickened).

Can be classified by use of OCTG (casing, tubing and drill pipe, and so on), line pipes, boiler tubes, mechanical structural tube, gas cylinders, hydraulic prop tube tube, geo-tubes, tubes for chemical industry (high pressure chemical fertilizer, petroleum cracking tubes) and tube for shipping.
