Chemical, medical, food, light industry, mechanical instruments and other industrial pipelines and mechanical structural parts. In addition, bending, torsional strength of the same, lighter weight, but also widely used in the manufacture of mechanical parts and engineering structure. Also used in the production of conventional weapons, barrels, shells and so on.
In the open end of the hollow part of the length, and the length of the cross-section of the larger steel pipe circumference, stainless steel tube can be called steel pipe. When the cross-section length and length is relatively small, can be called tube or pipe, belonging to the pipe category.
Stainless steel pipe is an economical cross-section steel, is an important product of the steel industry, usually about 8% of the total iron and steel, about 16%, widely used in the national economy.
Steel pipe has a hollow part, the most suitable for liquid, gas and solid pipe; also has the same weight of steel, steel pipe cross-section coefficient, bending and torsional strength, has become a variety of mechanical and building materials important material.
