Classification of Stainless Steel Tube

Date:2017-10-30    keywords:stainless steel tube
Production methods
Stainless steel tube according to the production method is divided into two categories of stainless seamless pipe and stainless welded pipe, stainless seamless steel pipe can be divided into hot-rolled tube, cold-rolled tube, cold-drawn tube and extrusion pipe, cold drawing, cold rolling is the second Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.

Section shape
Stainless steel tube by cross-sectional shape can be divided into tube and shaped tube. Shaped tube with rectangular tube, diamond-shaped tube, oval tube, hexagonal tube, all directions and a variety of cross-section asymmetric tube. The profiled tube is widely used in various structural parts, tools and mechanical parts. Compared with the tube, shaped tube generally have a larger moment of inertia and cross-section modulus, a greater bending, torsion ability, can be large greatly reduce the weight of the structure, saving steel.

Tube end shape
Stainless steel tube according to the pipe end state can be divided into light pipe and wire tube (with threaded steel pipe). Car tube can be divided into ordinary car wire (transport water, gas and other low-pressure pipe, the use of ordinary cylindrical or tapered pipe thread connection) and special thread pipe (oil, geological drilling pipe, for important car wire, Special thread connection), for some special tube, to compensate for the effect of thread on tube end strength, usually in front of the wire before the pipe end thickening (thickening, thickening or thickening inside and outside).

Use classification
According to the use can be divided into oil pipe (casing, tubing and drill pipe, etc.), pipeline, boiler tube, mechanical structure tube, hydraulic prop pipe, cylinder tube, geological pipe, chemical pipe (high pressure fertilizer pipe, ) and ship management.
