Welded 316L SS

Fittings are formed from material that meets the same exacting standards as our process tubing. We begin the process with a heavier wall to offset the thinning that occurs during manufacturing. Cardinal UHP fittings undergo a thorough preparation process to insure corrosion resistance as well as stringent dimensional specifications for economical installation.

First, welds are mechanically polished, and when required, fittings are electropolished and passivated. All welds are 100% visually inspected and mass spectrometer helium leak tested to 1x10 -9 cc/sec. Finally, the fittings are cleaned, capped, and bagged to meet the required specification.
