Series 738 Transition for CPVC/HDPE Submittal
CPVC Glue x HDPE Transition Fitting
General: The transition fitting is constructed out of CPVC material, CPVC insert, and high-density polyethylene (HDPE) pipe. The CPVC and HDPE materials are joined together by hydraulically pressing the HDPE pipe into the CPVC coupling. The CPVC coupling portion of the transition fitting is machined with our multi-level barb system that provides a leak-free radial compressed joint. The HDPE portion of the transition fitting is cut to a specific length and is pressed into the CPVC coupling. A CPVC insert is installed to lock the CPVC coupling and HDPE pipe together thus forming a leak-proof joint.
System Performance
The transition fitting is designed to handle the pressure rating of the HDPE pipe with a 2:1 safety factor at 73.40 degrees Fahrenheit with a minimum 50-year design life.
Quality Assurance
The transition fitting shall be manufactured by Poly-Cam, Inc. Poly-Cam, Inc. shall provide quality assurance with regards to proper installation, compatibility, performance, and acceptance. The transition joint meets or exceeds the requirements of:
- ARRA requirements
Installation
HDPE pipe end: Install transition fitting to comply with the pipe manufacturer’s recommended procedures. All field welds shall be completed per Plastic Pipe Institute’s welding procedure for butt fusion.
CPVC coupling: Install the CPVC coupling so as to comply with the CPVC pipe manufacturer’s recommended procedures for solvent cement.
Solvent Cement needs to meet ASTM F493.
Material
