Tee FRP-CPVC

FRP-CPVC tees combine a CPVC inner liner with a fiberglass-reinforced plastic (FRP) structural wrap at the branch fitting, extending the composite pipe construction used in FRP-CPVC piping systems to the branch connection point.

Key characteristics:
• The CPVC inner liner provides the same chemical resistance and elevated temperature rating found in standard CPVC branch fittings, protecting the FRP structural layer from direct process media exposure.
• The FRP outer wrap reinforces the branch connection, which is typically the highest-stress point in a composite pipe system, with additional hoop and axial strength beyond what the CPVC liner alone would provide.
• This construction allows FRP-CPVC pipe runs to include branch connections without stepping down to a lower-pressure-rated, unreinforced fitting at the branch, maintaining consistent pressure capability throughout the system.
• Matching the composite construction of the pipe at the tee ensures the branch connection does not become the weak point in an otherwise reinforced piping system.

Because branch fittings inherently introduce greater mechanical stress than a straight pipe section, using a reinforced tee that matches the pipe's composite construction is particularly important for maintaining the system's overall pressure rating at every connection point.

Typical applications include large-diameter FRP-CPVC process piping systems requiring branch connections, and installations where both high chemical resistance and elevated pressure capability must be maintained at every point in the piping layout, including branches.
