About this Backing Ring
This BR-1000-1076-06/10 is an FRP (Fiber Reinforced Plastic) Backing Ring designed for use behind GRP stub flanges in industrial piping systems. With a nominal size of DN1000 and working pressure rated up to 6 Bar, it carries the bolt load on flanged connections to other equipment - pumps, valves, vessels, or matching steel flanges - without distorting the plastic pipe.
The drilling pattern matches EN1092 PN10, ensuring drop-in compatibility with industry-standard counter-flanges. Manufactured by Resin Transfer Moulding (RTM) - a closed-mold resin infusion process - this large-diameter Backing Ring is built to engineered tolerances with precise reinforcement positioning and constant material quality.
Like all FRP Backing Rings from BackingRing.com, this part is fully corrosion-free, lightweight relative to a metal equivalent, and intended for service in chemical processing, water and wastewater treatment, mining, marine and other demanding environments.
Common applications for DN1000 GRP Backing Rings
- Connecting GRP pipe spools to flanged pumps, valves and instrumentation
- Tie-ins between GRP sections and steel/ductile-iron piping in mixed-material plants
- Replacement of corroded metal backing rings in saltwater or chemical service
- OEM equipment skid assemblies requiring a lightweight, non-rusting flange backing
