Quick Detail:

ss pipe，stainless steel pipe，welded pipe

Stainless steel welded steel pipes for mechanical structures are mainly used for machinery, automobiles, bicycles, furniture, hotel and restaurant decoration and other mechanical parts and structural parts; stainless steel welded steel pipes for fluid transportation are mainly used for transporting low-pressure corrosive media.

Description:

Stainless steel welded pipe production process:

Stainless steel pipe is an economical cross-section steel and an important product in the steel industry. It can be widely used in life decoration and industry. Many people on the market use it to make stair handrails, window guards, railings, furniture, etc. There are two common materials: 201 and 304.

Stainless steel pipes have a wide range of applications in the national economy. Because the steel pipe has a hollow section, it is most suitable for use as a transportation pipeline for liquids, gases and solids. At the same time, compared with round steel of the same weight, the steel pipe has a large section coefficient and high bending and torsional strength, so it is also used in various mechanical and architectural structures. important material. Structures and components made of stainless steel tubes have a greater section modulus than solid components of equal weight. Therefore, stainless steel pipe itself is an economical cross-section steel that saves metal. It is an important part of high-efficiency steel, especially in oil drilling, smelting and transportation industries, followed by geological drilling, chemical industry, construction industry, machinery Industry, aircraft and automobile manufacturing, as well as boiler, medical equipment, furniture and bicycle manufacturing also require large quantities of various steel pipes. With the development of new technologies such as atomic energy, rockets, missiles and aerospace industries, stainless steel pipes have become increasingly important in the national defense industry, science and technology and economic construction.

Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, and economical. The thin-walled pipes and the successful development of new, reliable, simple and convenient connection methods have given them more irreplaceable advantages than other pipes. They will be used more and more in engineering. , the use will become more and more popular, and the prospects are promising.

Stainless steel is unique among metals because it already possesses many of the desirable properties required of building materials, and its development continues. Existing types are constantly being improved to make stainless steel perform better in traditional applications, and new stainless steels are being developed to meet the stringent requirements of advanced construction applications. Due to increasing productivity and quality improvements, stainless steel has become one of the most cost-effective materials chosen by architects.

Stainless steel combines performance, appearance and usage characteristics, so stainless steel will continue to be one of the best building materials in the world.
