Backing and Blanking Flanges for HDPE Piping

This category includes backing flanges and blanking flanges designed for mechanical jointing and flanged transitions in HDPE piping systems. Used alongside PE stub flange adaptors, these components enable secure connections to valves, pumps, metallic pipelines, and isolation points. Available in PP-steel, PP-V, epoxy-coated ductile iron, and profiled steel configurations, they ensure uniform bolt load distribution for SDR11 (PN16 water / PN10 gas) and SDR17 (PN10 water / PN5 gas) utility installations.
