Seamless steel pipes have hollow sections and are widely used as
pipelines for transporting fluids, such as oil, natural gas, coal
gas, water and some solid materials Compared with solid steel such
as round steel, steel pipe is lighter in weight when its bending
and torsional strength are the same, and it is an economic section
steel. It is widely used to manufacture structural parts and
mechanical parts, such as petroleum drill pipes, automobile
transmission shafts, bicycle racks and steel scaffolds used in
building construction. It can improve the material utilization
rate, simplify the manufacturing process, save materials and
processing time, and has been widely manufactured with steel pipes.
