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.
Description:
Pipe Specifications - ASTM A312/A312M: 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.
Spezilla supplies welded stainless steel tube per ASTM A312 or ASTM A358 as well as rolled and welded. We supply common grades of stainless steel such as 304, 304L, 316, and 316L in standard pipe sizes and schedules, including Sch 5, Sch 10, Sch 40s and Sch 80s. We also cater to less common stainless welded pipe requirements with grades like 304H, 316H, 309S, 310S, 317L, 321H, 347H, 410, and 410S, in addition to Duplex and Nickel Alloy grades.
