Manufacturing ASME SA213 TP316L Seamless Tube

Cold Rolled

Donghang Stainless holds sets of advanced cold rolling and cold drawing machines to produce large wide range 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 from best suppliers for seamless tube material, each billet is analysed 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. In fact, we perform some of the most strenuous testing prior to releasing products, such as 100% hydrotesting of coils, 100% eddy current testing of straight length tubing and 100% positive material identification. We also thoroughly inspect all incoming raw material prior to use and send out samples from every heat treatment or lot for an independent verification of chemical analysis by an independent laboratory.
