  • 1. 1.What is ASTM A672?

    ASTM A672 Pipe is Standard Specification for Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperatures. ASTM A672 LSAW pipelines use a hot rolling process that may be standardized, quenched, disinfected, and is a thermostat and other heat treatment methods compatible.

  • 2. What is the difference between ASTM A671 and ASTM A672?

    A671 and A672 are EFW (Electric-Fusion Welded) Carbon Steel Pipes used for atmospheric and lower temperatures applications (A671) and high-pressure service at moderate temperatures (A672). As mentioned above, A671 is used for atmospheric and lower temperature application and A672 is used for high-pressure service applications at moderate temperature. However, if we compare the details e.g. A672 Gr.C60 & A671 Gr. CC60; the raw material plate used is same for both pipes & final mechanical properties are same. Heat treatment is same. The only difference between the 2 grades is only in the testing requirements. A672 requires weld sample drawn from a 500ft length of pipe and allows you to double the samples in case, original sample fails. A671 requires weld sample drawn from a 200ft length of pipe with no provision for a rejected weld.

  • 3. What is ASTM A672 grade C65 Class 22?

    The ASTM A672 Gr. c65 Cl22 has 0.98% manganese in the composition with carbon, phosphorus and sulfur. The minimum yield strength of the material is at 240MPa and the minimum tensile strength ranges from 450MPa to 585MPa. The conventional welding methods can be applied on the ASTM A672 Grade C65-class 22.The ASTM A671 Grade CC65 Class 22 EFW Pipes can be surface treated with paint, coating, FBE, galvanization, varnished, epoxy coatings, etc. They are designed with an outer diameter of 12-64 inches. The A671 CC65 Grade CL22 Low Temp Pipe is used in low-temperature.

  • 4. What is the wall thickness of A672 pipe?

    The specification nominally covers pipe 16 inches (400 mm) in outside diameter or larger and of ¼ inch (6 mm) wall thickness or greater. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.

  • 5. What are the properties of ASTM A672?

    The specification nominally covers pipe 16 inches (400 mm) in outside diameter or larger and of ¼ inch (6 mm) wall thickness or greater. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.

  • 6. What is A672 B65 material?

    ASTM A672 B65 Pipe is a larger diameter pipe ranging from 12 inches to 64 inches in diameter because the pipes are made through electric fusion welding of pressure vessel grade plates. The material has carbon, manganese, phosphorus, silicon and sulfur in the composition.
