Seamless Steel Pipe

ASTM A135A Seamless Steel Pipe have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, ASTM A135A Seamless Steel Pipe has the same bending and torsion strength and lighter weight. It is a kind of economical cross-section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, Bicycle racks and steel scaffolding used in construction.

ASTM A106Gr.B Seamless steel tube is a kind of low carbon steel widely used in petroleum, chemical and boiler industries. The material has good mechanical properties. A106-b steel pipe is equivalent to China's 20 steel seamless steel pipe, in accordance with ASTM A106/A106M high temperature operation carbon steel seamless steel pipe standard, grade B. It can be seen from ASME B31.3 piping standards for chemical plants and petroleum refineries that the temperature range of A106 material is -28.9~565℃.
