CPVC Vs. PVC Glue

PVC Pipes

• PVC pipes are made of polyvinyl chloride and are often used as piping for drainage, waste-water and ventilation. PVC pipes offer the stiffness of plastic but are soft enough to be pliable. PVC is lighter than conventional pipes and resistant to corrosion, making it a popular choice among professionals and amateurs alike.

CPVC Pipes

• Chlorinated polyvinyl chloride (CPVC) pipes are basically PVC pipes that have undergone the additional process of being chlorinated. As a result, CPVC pipes are stronger and have a higher resistance to heat. CPVC pipes are commonly used for transporting fluids such as potable water, corrosive fluids and fire suppression systems. CPVC pipes are typically used as an inexpensive substitute for copper piping.

PVC Glue

• PVC glue is designed specifically for PVC piping but also has the same tolerances as PVC piping. The temperature range of PVC is up to 140 degrees Fahrenheit; likewise, PVC cement is designed for use below that temperature. Using PVC glue to secure CPVC pipes is acceptable, provided the pipes are being used for cold-water plumbing (below 140 degrees F).

CPVC Glue

• CPVC glue is made to withstand a higher temperature range that is commensurate with CPVC piping. CPVC can consistently hold fluids with temperatures up to 200 degrees Fahrenheit. CPVC glue can also be used on ordinary PVC piping, since its tolerances exceed those of the piping.
