Series 834 Straight/Anodeless Riser with Flange End

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.
