Stainless steel pipe is a kind of hollow long round steel, which is mainly used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial transportation pipelines and mechanical structure components.  In addition, when bending and torsion strength are the same, the weight is light, so it is widely used to make mechanical parts and engineering structures.  Also commonly used for furniture and kitchen utensils.

It accounts for about 8 to 16 of the total steel, which is widely used in the national economy.  Because the steel pipe has hollow section, it is most suitable for liquid, gas and solid transportation pipeline.  At the same time, compared with round steel of the same weight, the section coefficient of steel pipe is large and the bending and torsion strength is large, so it has become an important material in various mechanical and architectural structures.  

Structures and components made of stainless steel tubes have a larger section modulus than solid parts with equal weight.  So, stainless steel pipe itself is a kind of economic section of saving metal steel, it is an important part of efficient steel, especially in oil drilling, smelting and transportation industry demand is bigger, followed by geological drilling, chemical industry, construction industry, machinery industry, aircraft and automobile manufacturing and boiler, medical equipment, furniture and bicycle manufacturing aspects also need a large number of various steel pipes.  With the development of new technologies such as atomic energy, rocket, missile and space industry, stainless steel pipe plays an increasingly important role in national defense industry, science and technology and economic construction.

Stainless steel pipe safety and reliability, health and environmental protection, economic application, pipeline thin wall and new reliable, simple and convenient connection method development success, so that it has more other pipe irreplaceable advantages, engineering application will be more and more, use will be more and more popular, promising prospects.  Because stainless steel already has many of the ideal properties required by building materials, it can be said to be unique,unmatched, unparalleled in metal, and its development continues.  In order to improve the performance of stainless steel in traditional applications, the existing types have been improved, and new stainless steel is being developed to meet the strict requirements of advanced building applications.  

Due to the continuous improvement of production efficiency and quality, stainless steel has become one of the most cost-effective materials chosen by architects.  Stainless steel combines performance, appearance and use characteristics, so stainless steel will remain one of the best building materials in the world.
