PPCH FR Pneumatic Piping comparison

PPCH vs PPR pipe for compressed air

PPR was developed for domestic plumbing. On a compressed-air header it sags between supports, moves with temperature and cannot run in the sun. PPCH was engineered for the job.

Parameter	PPCH FR Pneumatic Piping	PPR / PPRC pipe
MRS at 20 °C, 50 years	12.5 MPa	10 MPa
CRS at 70 °C, 50 years	5.93 MPa	3.2–3.6 MPa
Tensile strength at yield	26 MPa	24 MPa
Flexural modulus	3000 MPa	800 MPa
Design stress	4.3 MPa	2.13 MPa
Thermal expansion	0.035 mm/m·K	About 0.15 mm/m·K
Life in direct sunlight	10–20 years	2–3 years
Bore at 63 mm, PN 16	50 mm	45 mm
Bore at 110 mm, PN 16	87 mm	79 mm
Identification	Blue strip, pneumatic convention	None

What it means on your plant

About 21–24% more flow area
From 63 to 110 mm at PN 16, the same outside diameter carries more air.
Less sag, fewer supports
Nearly four times the flexural modulus and a quarter of the expansion.
Outdoor headers
The carbon UV layer allows rooftop and yard runs.
