Thermal Expansion
Expansion does NOT vary with pipe size. The stresses developed in CPVC are
generally much smaller than those developed in metal systems for equal
temperature changes because of significant differences in elastic modulus.
Therefore, expansion loop requirements are not significantly different thatn
those recommended for copper tubing. Thermal expansion can generally be
accommodated at changes in direction. On a long straight run.

Low Bacteria Build up
CPVC piping supports
the lowest bacterial growth compared with traditional piping materials.

department for any further detailed information ).
Excellent Chemical Resistance
Transitions from FlowGuardTM CPVC to Other
Materials
Numerous specialty transitions incorporating rubber seals at the plastic-to
metal interface are available and should always be used on lines where normal
water temperature of 65 ºC or higher are anticipated. Male CPVC threaded
adaptors are also available for connecting valves and appurtenances on cold
water lines. TFE (Teflon) therad tape is always safe for making CPVC threaded
connections. Some paste-type sealants contain solvents that may be damaging to
CPVC. If you prefer to use a paste or pipe dope, always check with the
manufacturer regarding its compatibility with CPVC. Use of an improper paste or
dope can result in failure of CPVC systems.
Hangers and Supports
Because FlowGuardTM tubing is rigid, it requires fewer supports than
flexible plastic systems. For vertical runs, provide a support at each floor
level, plus a mid-story guide. For horizontal runs, support at 90 cm intervals
for diameter of 32 mm amd below and at 1.2 m intervals for larger sizes piping
should not be anchored tightly to supports, but rather secured with smooth
straps or hangers that allow for movement caused by expansion and contraction.
Most hangers designed for metal pipes are suitalbe for FlowGuardTM
Hangers should not have rough or sharp edges which come in contact with the
tubing.
This Means that CPVC
Needs less hangers and supports.
There is no unslightly "looping" of the pipe.
Is suitalbe for vertical risers.
Has a higher pressure bearing capability.
This leads to the same flow rate with a smaller pipe size.
Fire Rated Construction
Testing demonstrates that FlowGuardTM CPVC meets 25/50 flame spread
/smoke developed requirements for installations within plenums. Fire wall
penetrations must be sealed with approved materials or devices, such as those
listed in the UL Building Materials Directory. Consult the local building
official in your area.
