Hot rolling, extrusion, cold drawing and cold rolling this several basic types, according to the cross section shape can be divided into round tube and special-shaped tube, steel tube is widely used, but there are some square, rectangle, semicircle, hexagonal, equilateral triangle, octagonal shaped stainless steel tube, etc. Stainless steel pipe according to the cross-sectional shape can be divided into circular tube and special-shaped tube. Special-shaped pipe with rectangular tube, the diamond, oval tube, six eight square tube and square beam impact tubes tube, all kinds of tube for asymmetry, etc. Abnormity tube is widely used in all kinds of parts, tools and machinery parts. Compared with the circular tube, special-shaped tube usually have large moment of inertia and section modulus, have bigger bending and torsional capacity, can greatly reduce the structure weight, save steel. Stainless steel pipe can be divided by profile shapes such as cross section pipe and variable cross section. Variable cross-section tube has a tapered tube, stepped pipe section and cycle, etc.
Car wire tube and can be divided into ordinary car wire tube (water, gas, such as low pressure tube, using common cylindrical or tapered pipe thread connection) and special thread tube (geology, oil drilling pipe, for important car wire tube, the use of special threaded connection), for some special tube, to compensate for the influence of the strength of pipe end of thread, often in a car wire before pipe end upset (internal upset, more external upset or inside and outside).
Stainless steel pipe connection is diversiform, common type of pipe fittings with compression type, pressure type, living type, push, push the thread, flange connection socket welding type, living type, welding and welding with traditional impact beam tubes connection way of derived series connection. The connection mode, according to its principle, its applicable scope is also different, but most are convenient installation, firm and reliable. Joint seal or gasket material, most choose to meet the requirements of national standard of silicone rubber, NBR and epdm and so on, from the user's worries.
Because the steel pipe has a hollow section, and thus the most suitable for liquid, gas, and solid pipeline; At the same time, compared with the same weight of round steel, steel pipe section flexural torsional strength coefficient is big, big, so all kinds of mechanical and architectural structure have become the important material. Use stainless steel tube structure and components, in side impact door beams under the condition of equal weight, than the solid parts has a larger section modulus. So, stainless steel pipe itself is a kind of metal saving economic cross section steel, it is an important component of efficient steel, especially in the oil drilling, refining and transportation and other industries demand is bigger, the geological drilling, chemical industry, building industry, industrial machinery, aircraft and automobile manufacture and boiler and bicycle manufacturing, medical equipment, furniture, etc are also requires a lot of all kinds of steel pipe. With atomic energy, rocket, missile and space industry, development of new technology, such as stainless steel pipe in the defense industry, the status of science and technology and economic development more and more important.
