STYLE S / SS
STYLE S / SS
Style S & 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.
Applications can impose severe-duty factors in addition to the maximum continuous operating pressure rating. These additional design requirements must be considered in selecting the appropriate Piedmont coupling.
Connections
Pressure Rating: 1500 psi (103 bar) with schedule 40s pipe (special alloys) with cut groove only – all sizes.
Components
*For the use of Style S & SS couplings on cyclic axial displacement systems, please consult with Piedmont for design and installation guidance.

*Pressure rating when cut grooves and sch 40 pipes are used.
Note : It is allowed a single hydrostatic proof test at 1.5 x rating pressure before being put in operation at its rated pressure or less.
Piedmont couplings are sold as a whole including the housing, the gasket, the bolts, nuts and washers when necessary. Please specify the coupling size and gasket type required.
