Series 834 Straight/Anodeless Riser with Flange End Submittal

Straight/Anodeless Flange Service Riser Transitions

The Poly-Cam Straight/Anodeless Flange Service Riser is a multi-level mechanical transition fitting. The polyethylene or pipe-quality copolymer material are hydraulically compressed into the transition fitting.


Relaxation of the pipe creates a seal to prevent leakage. Under pressure, the internal pressure within the pipe increases the sealing surface area on the barb. Under zero internal pressure, the compression and tensional strain created by the compression of the multi-level barbs are greater than the stress created by relaxation and/or thermal expansion and contraction. As the internal pressure increases, the connection between the pipe material and transition fitting increases. A stainless-steel insert is installed to reinforce the connection. This design meets ASTM D2513, Category 1. The fitting is designed to be suitable for service riser applications for natural gas services.

  • Sizes range from 1” to 12” Iron Pipe Size.
  • Flange dimensions to ANSI B16.5. Available in standard pound rating: 150, 300, and 600.
  • Designed for commercial and residential services.

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:

  • ASTM D2513 Category 1
  • ARRA requirements
  • DOT 192
  • ASTM F1973
