PPCH FR Pneumatic Piping comparison

PPCH vs aluminium pipe for compressed air

Aluminium push-fit systems install quickly, but every joint seals on an elastomeric O-ring. O-rings relax with vibration and thermal cycling, and leakage typically takes 20 to 30% of a compressor's output.

Parameter	PPCH FR Pneumatic Piping	Aluminium pipe
Jointing	Socket fusion and electrofusion: homogeneous fused joint	Push-fit with O-rings
Leak path at joints	None: no elastomer to age	O-rings relax with vibration and temperature swings
Surface roughness, Ra	0.1–0.3 µm	0.7–1.0 µm
Hazen–Williams C	145–150	130–135
Wall conductivity	0.135 Btu/hr·ft·°F	27.09 Btu/hr·ft·°F
Corrosion	None	Corrodes in humid air
Maintenance	Nil	O-ring joints need periodic upkeep
Size range	20–630 mm	Typically smaller bores

What it means on your plant

No O-rings to fail
A fused joint is the same material as the pipe, so there is no seal to age or relax.
Less condensate
Aluminium conducts heat about 200 times better than PPCH, so it cools the air and drops more moisture.
Large bore covered
PPCH runs from 20 mm drops to 630 mm headers on one fusion system.
