20 / 22 / 24SWG ASTM A269 TP321H welding stainless steel pipe , cold drawn welded tubes
Stainless steel welding bright annealed tube’s final surface is
polished and bright annealed. And the polished grade is includes
180 # , 320 # , 400 # , 600 # , 800 # . According to standard very
strictly , tubes which produced by us always have correct OD and WT
tolerance. And they are very suitable for chromatography industry.
