ASTM A 312/A 312M - 95a
Seamless and Welded Austenitic Stainless Steel Pipes
This specification covers austenitic steel pipe intended for high temperature and general corrosive service. H grades in the chemical
composition table are specifically for high temperature service. Dimensions and Tolerances
Dimensions
. All standard pipe sizes and wall thicknesses may be specified, subject to manufacturing limitations. Minimum wall
thickness pipe is also covered as a supplementary requirement.
Tolerances.
ASTM pipe
Manufacture Materials
. Refer to chemical composition table.
Manufacture
. In order to comply with this specification the pipe must be manufactured by an automatic welding process using no
filler metal, or it must be a seamless pipe. If a welded pipe has a nominal pipe size greater than 14 then it may be constructed from
two longitudinal sections, and hence have two longitudinal welds. The pipe may be either hot finished or cold finished.
Heat treatment
. Refer to heat treatment table and supplementary requirement S6.
Marking on each length of pipe
: Manufacturer’s make or brand, specification number, ‘WR’ if weld repaired, ‘NPS’ and schedule,
‘NH’ if no hydrotesting performed, ‘ET’ if eddy-current tested, ‘UT’ if ultrasonic tested. (NPS = Nominal Pipe Size.)
Finish and Repair
Finish
. The surface of the pipe must be clean and free of scale and contaminating iron particles. It can be bright annealed but may
be pickled, blasted or can be passivated.
Repair by welding
. Permitted on <20% of the weld seam length of welded pipe if >NPS 6 and having a wall thickness >0.200 in
(mm). Tungsten-arc welding process is used for repairs, with filler metal to a grade as specified in A 312 (not repeated here). Weld
repairs must be identified on the pipe and in test certificate.
