ASME SA213 TP316L Seamless Tube Manufacturing
Cold Rolled
Donghang Stainless holds sets of advanced cold rolling and cold drawing machines to produce a wide range of tubes.
Heat Treatment
Each tube should be heat treated in an annealing furnace within a solution temperature specified to relieve stress.
Pickling
Tubes shall be free of scale and suitable for inspection. A slight amount of oxidation is not considered scale. When bright annealing is used, pickling is not necessary.
ASME SA213 TP316L Seamless Tube Quality Control
Our stainless steel billets are from the best suppliers for seamless tube material, each billet is analyzed to ensure high quality, we have the tooling equipment and capabilities that will maintain strict tolerances, and we have the latest testing equipment and trained personnel to ensure consistent results. We perform some of the most strenuous testing before releasing products, such as 100% hydro testing of coils, 100% eddy current testing of straight-length tubing and 100% positive material identification. We also thoroughly inspect all incoming raw material before use and send samples from every heat treatment or lot for independent verification of chemical analysis by an independent laboratory.
