SMLS Pipe ASTM A106 GR.B 500mm ASME B36.10M
A106 steel pipes can be disintegrated on the basis of its application. Typical applications of steel pipes are in the area of water pipelines, industrial water lines, oil pipe lines, cross country pipe line, agriculture and irrigation pipes, tube lines for natural gas, chemical industries, automobile industry, construction industries and other purposes.
ASTM A106 Pipe Specification Material, A106 Seamless Pipe Products, ASTM A106 Seamless Carbon Steel Pipe
ASTM A106 pipe (also known as ASME SA106 pipe) belongs to American standard steel pipe. A106 contains three grades of A, B and C. A106A is C and Si components, and the tensile strength grade is 330MPa. A106B is C, Mn and Si components. Grade 415MPa, A106C is C, Mn, Si component, tensile strength grade is 485MPa. Among them, A106 is similar to China’s 20#; A106B is similar to China’s Q235; A106C is similar to Q345. A106 pipe belongs to the ordinary carbon steel series and is one of the commonly used materials. ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. Among them, cold drawn has higher dimensional accuracy than hot rolled, and the surface of hot rolled steel pipe is relatively rough.
The large-diameter A106 seamless steel pipe is hot-rolled steel pipe, and the small-diameter is cold drawn. The exported carbon steel seamless steel pipes need to be grooved, painted, and plastic pipe caps are added at both ends, and they need to go through commodity inspections. ASTM A106 Grade B Pipe (also known as ASME SA106 GR.B pipes) is used in power plants, boilers, petrochemical plants, oil and gas refineries, and ships where the piping must transport hot or cold liquids and gases under high pressures and temperatures. A106 GR. B Carbon Steel Seamless Pipes, A106 Gr B Sch 40 pipe, ASTM A106 Grade B Pipe Suppliers is available in various weights, sizes, and black and galvanized grades both seamless and electric welded. ASTM A106 Grade B Pipe sizes, less than 2″ is it normally delivered as a cold drawn product. 2″ and up are usually hot finished.
