无缝钢管具有中空截面，大量用作输送流体的管道，如输送石油、天然气、煤气

Seamless steel pipe having a hollow cross-section, as a large number of pipeline fluids, such as transportation of oil, gas, coal gas, water and some solid materials, pipes and the like. Compared with the steel solid round bar steel, the same, torsional strength in bending, lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive transmission, bicycle and frame construction using steel scaffolding steel pipe manufacturing annular parts, can improve material utilization, simplify the manufacturing process, saving material and machining time, has been widely used to make steel.

Seamless steel pipes have hollow cross-sections and are used in large numbers as pipes for the transport of fluids, such as those that carry oil, gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, when the iron and hand strength is the same, the weight is lighter, is an economic cross-section steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction to make ring parts with steel pipe, can improve material utilization, simplify the manufacturing process, Save materials and processing hours, has been widely used steel pipe manufacturing.

Seamless steel pipe has hollow section, which is widely used to transport fluid, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel tube is a kind of economic section steel with light weight when its bending and torsional strength are the same. It is widely used to manufacture structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction to manufacture circular parts. It can improve the utilization rate of materials, simplify the manufacturing process, save materials and add Working hours have been widely used to manufacture steel pipes.
