Products Style M
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.
FEATURES
Working Pressure
Pressure Rating: 450 psi (31 bar)
FEATURES
Pressure Rating
450 (31 bar) working pressure with schedule 40s pipe with cut groove only.
Pressure ratings for other pipe schedules and groove types, please refer to the table below or consult with Piedmont.
Components
- Housing
- 316 stainless steel, Grade CF8M (UNS # J92900) conform to ASTM A351/A351M requirements.
- Gaskets
- EPDM rubber, suitable for hot and cold water service. Two shapes of gaskets available: C-shaped or Flush-fit. NSF/ANSI 61 approved or equivalent for drinking water system components. Not suitable for petroleum service. *EPDM peroxide cured gaskets available upon request (for special applications such us chloramines, etc…)
- Bolts/Nuts/Washers
- Round-head, oval neck, 316 stainless steel bolts and heavy hex nuts conform to ASME B18.5 and B18.2, respectively.
NOTE: For the use of Style M couplings on cyclic axial displacement systems, please consult with Piedmont for design and installation guidance.
