Seamless Steel Pipe

Introduction:
The seamless steel pipe is a kind of round, square or rectangular steel pipe with hollow section and on seam on the edge. By punching the steel ingot and solid billet, the semi-manufactured steel pipes are produced. Then the seamless steel pipe is manufactured after the hot rolling, cold rolling, or cold drawing. Compared with solid steel pipe, it is an economic section steel with lighter weight and has a wide usage in the fields of structure and machinery elements. Such as petroleum drill pipe, gas transmission shaft, bicycle stand, and steel scaffold which is used in building operation.

Application:
With hollow cross-section, the seamless steel pipe is widely applied in fluid pipeline, such as the transport of petroleum, natural gas, coal gas, water and other solid materials.
