The Introduction of Stainless steel tube

Stainless Steel Tube is a hollow round steel bar, mainly used in petroleum, chemical, medical, food, light industry, machinery and instruments and other industrial pipes and mechanical structural components. In addition, bending, torsional strength of the same, lighter, so it is widely used in the manufacture of mechanical parts and engineering structures. Also used in producing all kinds of conventional weapons, the barrel, shells and so on.

classification

Stainless steel tube material into ordinary carbon steel, high-quality carbon steel, alloy pipe, steel pipe, bearing steel, stainless steel and precious metals in order to save and to meet the special requirements of the bi-metallic composite pipe, coatings and coated pipes . Many types of stainless steel tubes, for different purposes, different technical requirements, production methods are also different. Pipe diameter range of currently produced 0.1-4500mm, wall thickness 0.01 ~ 250mm. To distinguish its characteristics, generally follows the method of steel classification.


production methods
According to the mode of production, Stainless Steel Pipe is divided into two categories and pipe, seamless steel pipe can be divided into hot-rolled, cold-rolled, cold drawn tubes and squeeze tubes, cold drawn, cold-rolled secondary steel pipe processing; pipe into Longitudinal and spiral welded pipe.


Sectional shape
Stainless steel pipe can be divided by the cross-sectional shape of the pipe and shaped pipe. A rectangular shaped tube tube, diamond-shaped tube, oval tube, hexagonal tube, pipe and various sections Plus asymmetrical tubes. Shaped tube widely used in various structural parts, tools and machinery parts. Compared with the pipe, shaped tube generally have a greater moment of inertia and section modulus, a greater bending and torsional ability, can greatly reduce the structural weight, saving steel.

Stainless steel pipe can be divided according to the shape of the profile and other pipe section and variable cross-section tube. Variable Section possession conical tubes, pipes and stepped cycle section tubes.


The shape of the tube end
Stainless steel pipe tube end state can be divided according to the light pipe and threading pipe (with threaded steel pipe). Threading pipe can be divided into general threading pipe (conveying water, gas and other low-pressure pipe, ordinary cylindrical or tapered pipe thread) and special threaded pipe (oil, geological drilling pipe, pipe threading for important, the use of special threaded connection), for some special pipe, to compensate for the impact on the threaded pipe end strength, usually in front of the car to conduct wire tube end upsetting (thickening inside, outside or inside and outside the thick thick).
