ASTM A312 TP304L 1/2 inch SCH 5S Tig Welded Stainless Steel Tube

 

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.
