STYLE P
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.
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
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’’ – 3.0’’ | 250 psi (17 bar) |
| 4.0’’ | 225 psi (16 bar) |
| 6.0’’ – 8.0’’ | 100 psi (7 bar) |
