    ASTM A778 304 304l 316 316l Welded Stainless Steel Tube Not Annealed

    SPEZILLA supplies welded tube per ASTM A 788 as rolled and welded. We supply common grades of stainless such as 304/304L and 316/316L in standard tube sizes and wall thicknesses, as well as more challenging stainless welded tube requirements including 304H, 316H, 309/S, 310/S, 317/L, 321/H, 347/H, 410, 410S, Duplex 2205, Duplex 2507, and more.

    We can even supply material with wall thicknesses up to 3″ thick! Diameters sizes range from 1/8″ up to 96″. All welded tube products can be cut to size. Specialty testing services can also be provided. Stainless tubes can be polished per request and cut to size.


    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.
