ASTM A672-96(2005)

Standard Specification for Electric-Fusion-Welded Steel Pipe for High-Pressure Service at Moderate Temperatures

SCOPE
1.1 This specification covers steel pipe: electric-fusion-welded 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.
1.2 The specification nominally covers pipe 16 in. (405 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.
1.3 Several grades and classes of pipe are provided.
1.3.1 Gradedesignates the type of plate used.
1.3.2 Classdesignates 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 Class designations are as follows (Note 01:Note 1
Selection of materials should be made with attention to temperature of service. For such guidance, Specification A 20/A 20M may be consulted.
1.4 The values stated in inch-pound units are to be regarded as the standard.

operators qualified in accordance with the ASME Boiler and Pressure Vessel Code, Section IX.
5.2.2 The welds shall be made either manually or automatically by an electric process involving the deposition of filler metal.
5.2.3 The welded joint shall have positive reinforcement at the center of each side of the weld, but not more than ⁄8 in. (3.2
mm).This reinforcement may be removed at the manufacturer’s option or by agreement between the manufacturer and purchaser.
The contour of the reinforcement shall be smooth, and the deposited metal shall be fused smoothly and uniformly into the plate
surface.
5.2.4 When radiographic examination in accordance with 9.1 is to be used, the weld reinforcement shall be governed by the
more restrictive provisions of UW–51 of Section VIII of the ASME Boiler and Pressure Vessel Code instead of 5.2.3 of this
specification.
5.3 Heat Treatment—All classes other than 10, 11, 12 and 13 shall be heat treated in furnace controlled to 6 25°F (14°C) and
equipped with a recording pyrometer so that heating records are available. Heat treating after forming and welding shall be to one
of the following:
5.3.1 Classes20,21,22,and23pipeshallbeuniformlyheatedwithinthepost-weldheat-treatmenttemperaturerangeindicated
in Table 2 for a minimum of 1 h/in. of thickness or 1 h, whichever is greater.
5.3.2 Classes 30, 31, 32, and 33 pipe shall be uniformly heated to a temperature in the austenitizing range and not exceeding
the maximum normalizing temperature indicated in Table 2 and subsequently cooled in air at room temperature.

to the tempering temperature indicated in Table 2 as a minimum and held at temperature for a minimum of ⁄2 h/in. of thickness
or ⁄2 h, whichever is greater, and air cooled.
5.3.4 Classes 50, 51, 52, and 53 pipe shall be uniformly heated to a temperature in the austenitizing range, and not exceeding
the maximum quenching temperature indicated in Table 2 and subsequently quenched in water or oil. After quenching the pipe
shall be reheated to the tempering temperature indicated in Table 2 as a minimum and held at temperature for a minimum of ⁄2
h/in. of thickness or ⁄2 h, whichever is greater, and air cooled.
