Products Style P

Rated 4.5/5 based on 17 customer reviews
Product Line: PIEDMONT
| |

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.

Models:

ASSETS

The non-metallic Style P plastic composite provides the ultimate corrosion resistance with adequate strength for a broad range of duty applications and throughout the low and moderate pressure range up to 6.9 bar (100 psig) to 13.8 bar (200 psig) depending on pipe size in the range of 2.5-inch to 8-inch nominal pipe size.

FEATURES

Connections

The P style coupling is designed expressly for brackish, MF, UF and NF membrane filtration, permeate and other low pressure applications.

PRESSURE RATING
2 X safety margin

 
0.75’’ – 2.5’’250 psi (17 bar)
3.0’’ – 4.0’’225 psi (16 bar)
6.0’’ – 8.0’’100 psi (7 bar)

Components

  • Housing
    • Plastic composite resin*, UV resistant, non-water absorptive. Completely corrosion resistant.
  • Gaskets
    • EPDM rubber, suitable for hot and cold water service. Two shapes of gaskets available: C-shaped or Flush-fit. NSF/ANSI 61 approved 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
    • Round / hexagonal head, oval neck, 316 stainless steel bolts and heavy hex nuts conform to ASTM F-593, Group 2, condition CW.

*This plastic composite is made of a homogeneous mix of polymers creating a strong plastic able to sustain pressures up to 200 PSI (14 bar). This material is ideal for fresh and brackish water applications

*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.

NOTE: For the use of Style P couplings on cyclic axial displacement systems, please consult with ATS Water technology for design and installation guidance
