SUS 317 TP317L stainless welded pipe Sch5S-160S For High Temperature Service
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.
Pipe Specifications - ASTM A312/A312M: 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.
Grade: Austenite,Ferritic, Super-Ferritic, Duplex Stainless Steel
Standard:ASTM A249/A213/A269/A554/A270/A312/A268/A778/A789/A790
DIN11850/17456/17458/SMS/ISO2037/ISO1127/EN10217-7 EN10216
OD:3.175-1016mm,WT: 0.5-20mm,Length:1000-20000mm,Type: Seamless, Welded
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.
