What is ASTM A694 F52/ F60/ F65 Carbon Steel Flanges?

  • This specification covers forged or rolled steel pipe flange, forged fittings, valves, and parts suitable for use with high-strength transmission-service pipe. Included are flanges, fittings, and similar parts ordered either to dimensions specified by the purchaser or to ASME or MSS dimensional standards referenced in section 2.
  • Several grades of material, based on minimum yield strength requirements, are covered, as indicated in Table 1.
  • Supplementary Requirements are provided. Supplementary Requirements S 1 is provided for use when purchaser approval is required for repair welding.
  • This specification is expressed in both inch-pound units and in SI units. However, unless the order specifies the applicable “M” specification Designation (SI units), the material shall be furnished to inch-pound units.
  • The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the order. Combining values from the two systems may result in non-conformance with the standard.
