Stainless steel pipe is a kind of hollow long round steel, which is an important product in the steel industry. It is widely used in the national economy. Because the steel pipe has hollow section, it is suitable for liquid, gas and solid transportation pipelines. At the same time, compared with the same weight of round steel, the steel pipe has large section coefficient, large bending and torsional strength, so it also becomes an important material in various mechanical and architectural structures. The structure and components made of stainless steel tube have larger section modulus than solid components under the condition of equal weight. Therefore, stainless steel pipe itself is a kind of economical section steel which can save metal. It is an important part of steel, especially in oil drilling, smelting and transportation industries. Secondly, geological drilling, chemical industry, construction industry, machinery industry, aircraft and automobile manufacturing, as well as boiler, medical equipment, furniture and bicycle manufacturing, etc. also need a large number of various aspects. Steel pipes. Nowadays, with the development of new technologies such as atomic energy, rocket, missile and aerospace industry, stainless steel tube plays an increasingly important role in national defense industry, science and technology and economic construction.
Attributes of stainless steel pipe: Surface resistance less than 1000 MΩ; wear protection; retractable; excellent chemical resistance; good alkali metal and acid resistance; strong toughness; Flame retardant.
According to the production mode, the stainless steel pipe is divided into two types: seamless pipe and welded pipe. The seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe, etc. Cold drawing and cold rolling are secondary to steel pipe. Processing; welded pipes are divided into straight welded pipes and spiral welded pipes.
According to the application, it can be divided into oil well pipe (casing, oil pipe and drill pipe, etc.), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, petroleum cracking pipe) and ship pipe, etc.
