O-PVC CRITICAL

PN25 CLASS 500

Max Headroom For High Stakes Applications

Long Rising Mains

FLOKING CRITICAL OPVC PIPE is built for steep elevation gains where static head plus start/stop surges exceed the PN16 envelope. The thin-wall, high-strength OPVC construction delivers high hoop strength with low weight, enabling faster handling on difficult slopes. Result: reliable delivery to hill reservoirs with lower transport/installation effort than DI and simpler maintenance over life.

Aggressive Transients Process

Where fast valve operations, pump trips, or operational upsets create high transients, FLOKING CRITICAL OPVC PIPE offers a safer margin while you implement practical surge controls. The material’s toughness and smooth bore mitigate water-hammer risk and energy loss. For when validated transients push beyond PN16 despite mitigation.

High Risk Critical Feeders

Hospitals, industrial plants, data centers, and zone backbones cannot fail. PN25 delivers additional safety margin against surges, accidental valve operations, and pressure excursions, with corrosion-free service that preserves hydraulic capacity. Maintain warranty by following joint QC, restraint design, and staged hydro-testing with temperature/pressure logs.

Fire Water Mains

Critical fire rings and hydrant feeds demand headroom, predictable joints, and minimal downtime. FLOKING CRITICAL OPVC PIPE provides a validated pressure envelope with gasketed rubber joints speed for rapid install and repair. Corrosion-free OPVC maintains internal diameter for consistent flow, while lighter sections simplify routing around buildings and plant utilities.

River Crossings

Crossings add access constraints and load uncertainty. FLOKING CRITICAL OPVC PIPE provides a robust pressure envelope for siphons and inverted crossings with the handling advantage of lightweight OPVC. Use restrained joints, proper bedding, and thrust blocks at all fittings; verify profile vents and scour protection.

Special & Difficult Terrains

Cliffs, tight corridors, rock cuts, and unstable soils increase installation risk. PN25 combines high pressure class with lighter sections for safer handling, fewer lifts, and faster progress in constrained sites. Specify bedding/embedment to spec, restrained joints at changes in direction, and monitoring during commissioning.
