Application of ASTM 106 Carbon Seamless Steel Pipe
Pipe ordered under this specification shall be suitable for bending, flanging, and similar forming operations, and for welding. When the steel is to be welded, it is presupposed that a welding procedure suitable to the grade of steel and intended use or service will be utilized.Details of ASTM A106 Seamless Steel Pipe We can supply
Manufacture:Seamless process, cold drawn or hot rolled Cold drawn: O.D.: 15.0～100mm W.T.: 2～10mm Hot rolled : O.D.: 25~700mm W.T.: 3~50mm Grade: Gr.A, Gr.B, Gr.C. Length: 6M or specified length as required. Ends: Plain End, Beveled End, ThreadedManufacturing Process of ASTM A106 Seamless Steel Pipe
ASTM A106 seamless steel pipe are produced either by cold-drawn or hot rolled, as specified. Hot finished pipe need not heat treated. When hot finished pipe is heat treated ,it shall be heat treated at a temperature of 1200°F or higher. Cold drawn pipe shall be heat treated after final cold draw pass at a temperature of 1200°F or higher.Chemical Composition of ASTM A106 Seamless Steel Pipe
