ASTM A672 Standard Specification for Electric-Fusion-Welded Steel
Pipe for
High Pressure Service at Moderate Temperature covers
electrical-fusion-welded steel
pipe for high-pressure service at moderate temperature. Heat
treatment may or may not be
required to attain the desired properties or to comply with
applicable code requirements.
An analysis of each mill heat of plate material shall be made,
also, an analysis of the
finished deposited weld material from each 500 ft or fraction
thereof shall be made.
The mechanical test requirements includes one tension test specimen
to represent each
lot of finished pipe, and one transverse-guided-weld-bend test (two
specimens) to
represent each lot of finished pipe. Also, radiographic examination
shall be made on the
full length of each weld.
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. [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.
1.3 Several grades and classes of pipe are provided.
1.3.1 Grade designates the type of plate used.
1.3.2 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.
