 Harvel CPVC pipe is produced from a specialty blend of CPVC material with unique physical properties desirable for piping applications (i.e., improved impact resistance and good fire resistance capabilities).
The CPVC product line includes schedules 40 and 80 piping from 1/4"
through 24" diameters. Harvel CPVC piping systems can handle
more than three-fourths of the temperature/pressure requirements
of today’s typical process plants. CPVC pressure pipe has
an upper working temperature limit of 200°F (93°C), or approximately
60°F (15°C) above that of Type I Grade I PVC. As with all
thermoplastic piping systems, CPVC’s ability to withstand
pressure varies with pipe diameter, wall thickness, and temperature.
For pressure piping applications it is recommended for temperatures
as high as 200°F (93°C) when appropriate temperature de-rating
factors are applied. As the pipe diameter and temperature increases,
the pressure rating of the product decreases. For example, 1/2"
Schedule 80 CPVC pipe is engineered for continuous service of 850
psi @ 73°F (23°C). The same pipe in service @ 180°F
(82°C) carries a maximum working pressure rating of 210 psi
at this temperature. 6" Schedule 80 CPVC pipe is designed for
270 psi @ 73°F, and 54 psi @ 200°F.
