Large Diameter Welded Stainless Steel Tubes SS304 Pipe 400BN
Manufacture:
In order to comply with this specification welded stainless steel
tube must be manufactured by an automatic welding process using no
filler metal, or it must be a seamless pipe. If a welded stainless
steel tube 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.

Finish and repair:
The surface of the welded stainless steel tube 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 stainless steel tube 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.
