Description

Piedmont Style D Grooved Coupling With 316 SS Hardware + SB Nuts

Style D 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.

Duplex stainless steel is highly resistant to chloride corrosion because of its metallurgy and microstructure. Used for high pressure couplings for seawater installation our duplex alloy is made of two metallurgical phases with each their role to play in the efficiency of the couplings.

Austenite for nobility

Ferrite for strength

The two phases are homogenized to form a metallic composite analogue to epoxy/glass composite. Our duplex is highly resistant to corrosion and offers twice the tensile and yield strength compared to stainless steel 316. Our duplex alloy is CE8MN and offers better mechanical properties when compared to conventional 316L stainless steel.

Featured Highlights:

Pressure Rating 1200 psi (82 bar) with schedule 40s pipe (special alloys) with cut groove only – all sizes.

Duplex or SuperDuplex* stainless steel type CE8MN, conform to ASTM A995 Grade 2A. Piedmont also offers this coupling style in CE3MN (Grade 5A) for even higher corrosion resistance

EPDM rubber gasket, suitable for hot and cold water service. NSF/ANSI 61 approved for drinking water system components. Not suitable for petroleum service.

Nuts and bolts are Round-head, square-neck, type 316 stainless steel bolts and heavy hex nuts conform to ASTM F-593 and 594, Group 2, condition CW.

Sizes are 3/4″- 12″ Nominal size pipe.
