ASTM A179/ASTM A333 seamless pipe,Large and Small Diameter Seamless pipe&tube

Seamless steel pipe is a kind of long steel with hollow section and no joint around it. Steel pipe has hollow section, which is widely used as pipeline for conveying fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steels such as round steel, steel pipe has lighter weight when its bending and torsional strength is the same. It is an 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 scaffolding used in construction.
