Seamless Steel Pipe is Steel pipe with
hollow cross-
section, a large number of
pipes used to transport
fluid, such as the
transportation of
Oil, natural
gas, gas, water and some solid
materials such as pipes.
Steel and round steel and other solid steel compared to the same
bending strength in the same bending, lighter
weight, is an economic section of steel, is widely used in the manufacture of
structural parts and
mechanical parts, such as oil
drill Pipe, Bicycle frames and steel
construction scaffolding.
carbon Seamless Steel
pipe manufacturing ring parts can
improve Material utilization, simplify the manufacturing process, save materials and
processing time, such as rolling bearing rings, jackets, etc., has been widely used to manufacture steel pipe
