Shandong Xinyiying Metal Material Co., Ltd. specializes in angle steel, I-beam steel, channel steel, H-section steel, round steel and square tube seamless tube plate produced by Angang, Tangshan, Laigang, Jinxi, Tianjin and other major steelworks. They are sold 24 hours a day without rest during holidays.
Seamless steel pipe has hollow section, which is widely used as pipeline for fluid transportation, such as pipeline for oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsion strength, lighter weight, and is a kind of economic section steel. It is widely used in manufacturing structural and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction. It can improve the utilization rate of materials, simplify the manufacturing process, save materials and add more. Man-hour has been widely manufactured with steel pipes.
