DIN 1629 ST37 Seamless Carbon Steel Pipe, 20 Inch, SCH 80, 12 Meter, Hot Rolled.

Introduction
Carbon steel seamless steel pipe is a kind of long strip steel. The steel pipe has a hollow section and is widely used as a pipeline for conveying fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same flexural and torsional strength and light weight. It is an economic section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as petroleum drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction.
Making ring parts with steel pipe can improve the utilization ratio of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, Jack sleeve, etc. At present, steel pipe has been widely used to manufacture.
Steel pipe or all kinds of conventional weapons indispensable materials, barrel, barrel and so on are made of steel pipe. The steel pipe can be divided into round pipe and special-shaped pipe according to the shape of cross-sectional area. Because the circular area is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. In addition, the ring section under internal or external radial pressure, the force is more uniform, therefore, most of the steel pipe is a circular pipe.
Making ring parts with steel pipe can improve the utilization ratio of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, Jack sleeve, etc. At present, steel pipe has been widely used to manufacture.
It is divided into 10# seamless steel pipe ,20# seamless steel pipe ,4# seamless steel pipe and so on.
