GRP Pressure Pipe — Water Transmission
Filament-wound GRP pressure pipe for buried and aboveground potable / raw water.
Our filament-wound GRP pressure pipe is designed for buried and aboveground potable-water, raw-water and reclaimed-water transmission. A resin-rich corrosion barrier on the inside, a helical filament-wound structural wall, and gasketed bell-and-spigot joints give a leak-tight, corrosion-free alternative to ductile iron and steel pipe — with hydraulic smoothness that keeps pumping head low over a 50-year design life.

Frequently Asked Questions
DN sizes and pressure classes do you cover?
Industry-typical DN100–DN4000, PN6–PN25, stiffness SN2500–SN10000 N/m², subject to our confirmed product line.
AWWA C950 vs ASTM D3517 — what’s the difference?
Both cover machine-made fiberglass pressure pipe for water; AWWA C950 is the widely referenced water-industry standard, ASTM D3517 the ASTM pressure-pipe specification.
How are joints sealed?
Gasketed bell-and-spigot for buried mains; flanged joints where dismantling is needed.
