The shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas, which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling, which is connected by special thread for important threading pipe). For some special pipes in order to make up for the impact of thread on the strength of pipe end, the pipe end is usually thickened before threading (inner thickening, outer thickening or inner and outer thickening).Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x.. Series & mdash; Martensitic precipitation hardening stainless steel.Honesty and mutual benefit,The accumulation of organic impurities caused by decomposition products and the pollution of some other metal impurities. There is no turnover of long-term stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe to avoid price difference. The price is % higher than the market price! The price of more than one ton is higher! So that the nickel bath can not get the ideal bright nickel coating, it is necessary to carry out large-scale treatment. In the solution of bright nickel plating on stainless steel pipe, the brightener has developed rapidly and has many varieties. To sum up, the development of brighteners has experienced four generations. Instead of the original product, saccharin and butynediol can be plated with bright nickel with high flatness. Its application flourished in the s and s. It seems that due to the instability of butynediol in the nickel plating bath, short service life and rapid accumulation of organic impurities, the nickel bath needs to be treated frequently. Therefore, epoxy chloropropyl or epoxy is branched with butynediol to synthesize the second-generation nickel plating brightener, such as b brightener. The situation has improved. Be and retain alkynyl. Later, pyridinyl is polymerized to form the third-generation product, Faster light output, less amount of brightener and longer service life. Now it further uses various combinations of nickel plating brightener intermediates to form a new brightener, which has developed to the fourth generation of products. It has less use, faster light output speed and longer treatment cycle. According to the connection and rolling process, stainless steel pipes with deep plating capacity mainly include hot-rolled, hot-rolled and cold drawn (rolled) stainless steel pipes. According to the difference of metallographic structure of stainless steel, it mainly includes semi Ferritic and semi martensitic stainless steel pipe, martensitic stainless steel pipe,AraucoStainless steel pipe making machine, austenitic stainless steel pipe, austenitic ferritic stainless steel pipe, etc.Austenitic stainless steel. It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.Refining and transportation industries are in great demand. Secondly, geological drilling, chemical industry, construction industry, machinery industry,AraucoStainless steel inner liner, aircraft and automobile manufacturing, boiler medical equipment, furniture and bicycle manufacturing also need a large number of various steel pipes. With the development of new technologies such as atomic energy, rocket, missile and aerospace industry, science and technology and economic construction.
According to the purpose, it can be divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, hydraulic prop pipe gas cylinder pipe, geological pipe, chemical pipe (high-pressure chemical fertilizer pipe, petroleum cracking pipe) and marine pipe.Standard requirements,Body austenitic stainless steel seamless steel pipe and welded steel pipe stainless steel pipe for mechanical structure stainless steel pipe for ordinary pipe stainless steel pipe for boiler, accounting for more than % of the total consumption of automobile stainless steel, and % is ferritic stainless steel. The exhaust gas produced by automobile engine is from the rear of intake pipe, front pipe, hose, converter and center pipe. The common steel grades of exhaust system are L, l, etc. it is mainly used in automobiles Stainless steel welded pipe. It is estimated that the stainless steel pipe used in automobile accounts for about % of the consumption of stainless steel pipe in the whole downstream. L stainless steel pipe, s stainless steel pipe and L stainless steel pipe are provided for a long time. The products are complete, excellent quality and favorable price. The use ratio of stainless steel pipe and welded pipe is about :.The stainless steel strip is supplied in coils, also known as strip steel. It is divided into hot rolling and cold rolling, as well as ordinary steel strip and high-quality steel strip. There are many kinds of stainless steel belts! Wide use! There are: stainless steel belt, stainless steel belt, stainless steel belt, stainless steel belt, stainless steel belt stainless steel belt, stainless steel belt, J stainless steel belt, S stainless steel belt L stainless steel belt, L stainless steel belt, S stainless steel belt, stainless steel iron belt, etc! Thickness: .mm-mm, width: mm-mm, can be customized without standard!The shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas, which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling, in order to make up for the impact of thread on the strength of pipe end, the pipe end is usually thickened before threading (inner thickening, outer thickening or inner and outer thickening).Arauco,Various welding methods of combined welding stainless steel welded pipe have their own advantages and disadvantages. Combined welding methods include argon arc welding plus plasma welding, high-frequency welding plus plasma weldingGood ductility, used for forming products. It can also be machined to harden rapidly. Good weldability. Wear resistance and fatigue strength are better than stainless steel.Crimping: during crimping, the convex part of the pipe fitting is placed in the concave groove of the die and the jaw is perpendicular to the pipe axis.
