How would PPR and CPVC compare in terms of price, operating pressure, collapse pressure, and fire rating?

From the meter to the house, is there a need for CPVC/PPR or would normal u-PVC do?

PPR pipes come in many flavors, Click on;

What flavor are you referring to?

Dear Tom,

I am inferring to normal CPVC pipe, not the composites... However for the special applications which require temperatures higher than 70 deg, normal PPR wouldn't do and CPVC would be a better substitute ( am I mistaken? )?

I have been asked for an advice to an investor who wants to invest in CPVC (flowguard) pipe manufacturing in a region in the Middle east where only PPR is used for cold and hot water applications. The purpose of my questions is to assess the value of the investment.

Appreciate any info...

Cheers
Jack
