PPRCT FR Composite Piping comparison

PPRCT vs HDPE pipe for industrial water

HDPE is a sound choice for buried water mains. Above ground in a plant, carrying chilled or hot water on racks, its low stiffness, high expansion and butt-fusion beads count against it.

Parameter	PPRCT FR Composite Piping	HDPE pipe
Material	Glass-fibre reinforced PP-RCT composite	Polyethylene
Standard	ISO 15874-2:2012	IS 4984 / ISO 4427 (water supply)
Temperature	−5 °C to +95 °C, per selection chart	Water supply rating up to 40 °C
Thermal expansion	0.035 mm/m·K	About 0.2 mm/m·K
Supports and sag	Stiff; fewer supports	Flexible; more supports at short spacing
Bore at 110 mm, PN 10	95 mm	90 mm
Jointing	Socket fusion to 160 mm, electrofusion to 630 mm, no bead	Butt fusion leaves an internal bead at every joint

What it means on your plant

Hot and chilled lines
PPRCT is rated to 95 °C; pressure-rated HDPE water pipe is rated to 40 °C.
Tidy racks
About a sixth of the expansion and far higher stiffness, so straight runs with fewer clamps.
Full bore at joints
Electrofusion avoids the bead that costs up to 9% of flow area at each butt-fused joint.
