Style SS – 316 SS – 1500 psi rated – 3″


SKU: SS0300-C-BTSS-SB-SS Category:


Piedmont Style SS Grooved Coupling

Style SS couplings incorporate the more noble, duplex-alloy construction, which although initially more expensive, offers the superior corrosion resistance and corresponding better longevity for highly corrosive environments compared to the Style B coupling which is constructed from 316 alloy. Consult Piedmont application engineering for guidance on the selection of metal alloy for your application.

Pressure Rating: 1500 psi (103 bar) with schedule 40s pipe (special alloys) with cut groove only – all sizes.

Note: Working pressure ratings based upon generally accepted pressure piping design standards and testing in accordance with ASME Section VIII Division 1 pressure vessel test method.

*For the use of Style SS couplings on cyclic axial displacement systems, please consult with Piedmont for design and installation guidance.
