Carbon steel pipe is a strip. Steel and round steel and other solid steel, bending torsional strength, lighter weight, is an economic section steel, widely used in the production of structural and mechanical parts, such as oil drill pipe, drive shaft, bicycle frame and construction steel Scaffolding work, and so on. Steel ring sections, which can be used to simplify information on the progress of the production process, save data and processing time, such as rolling bearing rings, jackets, steel pipes are widely used in manufacturing. Steel pipe is a variety of conventional weapons is not lack of material, steel pipe, so that guns, barrels, etc.Steel pipe according to the cross-sectional shape of the different can be divided into tube and shaped tube. Because the circumference of the plane under the conditions, the largest circular area,
with a circular tube can transport more liquid. In addition, the circular part of the internal or external radial pressure, pressure is relatively uniform, therefore, the vast majority of steel pipe is a tube.
Element of the raw material
(1) The main structure
Taiyuan that should be used in high-quality seamless steel pipe, industrial and civil construction, usually can choose according to the nature of the work is usually separated from the quality of Taiyuan, the quality of seamless steel pipe is often the same as the structure of the structure of large.
(2) Load conditions
Direct structural dynamic loading and strong seismic structure of the region should be selected to sense the function of good Taiyuan seamless steel pipe; usually accepted static load structure is optional Taiyuan seamless steel pipe prices are low.
(3) Connection
Welding process occurs welding deformation and welding stress and other shortcomings, structural cracks or brittle cracking risk. Therefore, the demand for raw materials should be a severe welding structure.
(4) The thickness of seamless steel tubes, thin roll more seamless steel pipe, rolling deflation than large, large thickness Taiyuan seamless steel pipe deflation ratio is small, so the thickness of thin steel pipe is not only very small, and plasticity, impact toughness and welding function also poor.
