Manufacturing Company DOES NOT
RECOMMEND the use of thermoplastic piping products
for systems to transport or store compressed air or gases, or
the testing of thermoplastic piping systems with compressed
air or gases in above and below ground locations. The use of
our product in compressed air or gas systems automatically
voids any warranty for such products, and its use against
our recommendation is entirely the responsibility and
liability of the installer.
WARNING: DO NOT USE COMPRESSED
AIR OR GAS TO TEST ANY PVC OR CPVC
THERMOPLASTIC PIPING PRODUCT OR
SYSTEM, AND DO NOT USE DEVICES
PROPELLED BY COMPRESSED AIR OR GAS
TO CLEAR SYSTEMS. THESE PRACTICES MAY
RESULT IN EXPLOSIVE FRAGMENTATION
OF SYSTEM PIPING COMPONENTS CAUSING
SERIOUS OR FATAL BODILY INJURY.
PVC Chemical Resistance
PVC is generally inert to most mineral acids, bases,
salts and paraffi nic hydrocarbon solutions. For more
information on PVC chemical resistance refer to
the Chemical Resistance of Rigid Vinyls Based on
Immersion Test, published by the GEON
®
Company.
To determine the maximum internal pressure rating at an elevated temperature, simply multiply the pipe
pressure rating at 73°F by the percentage specifi ed for the desired temperature.
