ASTM A672/A672M 2014 Edition, May 1, 2014 Standard Specification for Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperatures
More info
Description / Abstract:
This specification2 covers steel pipe:
electric-fusionwelded with filler metal added, fabricated from
pressure-vessel quality plate of any of several analyses and
strength levels and suitable for high-pressure service at moderate
temperatures. Heat treatment may or may not be required to attain
the desired properties or to comply with applicable code
requirements. Supplementary requirements are provided for use when
additional testing or examination is desired.
The specification nominally covers pipe 16 in. [400 mm] in outside diameter or larger with wall thicknesses up to 3 in. [75 mm], inclusive. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.
Several grades and classes of pipe are provided.
Grade designates the type of plate used.
Class designates the type of heat treatment performed during manufacture of the pipe, whether the weld is radiographically examined, and whether the pipe has been pressure tested as listed in 1.3.3.
NOTE 1—Selection of materials should be made with attention to temperature of service. For such guidance, Specification A20/A20M may be consulted.
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 may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the "M" designation of this specification is specified in the order.
2 For ASME Boiler and Pressure Vessel Code applications see related Specification SA-672 in Section II of that Code.
*A Summary of Changes section appears at the end of this standard
