DM Plastics and Steel backing rings and flange sets provide engineered support for bolted connections on HDPE pipe, delivering consistent alignment, load distribution and long‑term joint integrity. Our range includes PE backing rings, stub flanges, flange adaptors and complete bolt kits sized to suit common DN ranges and pressure classes, making valve tie‑ins, meter connections and manifold interfaces straightforward and reliable.
Manufactured from durable, corrosion‑resistant polymers and precision‑machined to ensure concentric alignment with pipe OD, our backing rings minimise flange face distortion and protect joints from mechanical stress. Components are produced to match HDPE dimensional requirements and to interface cleanly with standard metal valves and service hardware via BSP or flanged transitions.
Designed for practical installation and long service life, our backing ring solutions reduce on‑site rework and simplify assembly of flanged nodes in civil, municipal, mining and industrial systems. As part of our Producing Solutions approach, DMP&S can supply complete flange kits, bespoke flange assemblies and technical guidance to ensure compatibility and ease of installation for each project.
