About this Backing Ring
This BRPVC-65-92-10/150 is an FRP (Fiber Reinforced Plastic) Backing Ring designed for use behind PVC stub flanges in industrial piping systems. With a nominal size of DN65 and working pressure rated up to 10 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 ANSI B16.47 Class 150 B16.5 Class 150, ensuring drop-in compatibility with industry-standard counter-flanges. Manufactured by high-pressure Hot Pressing using Sheet Molding Compound (SMC), this size range is produced at scale with consistent wall thickness, precise bolt-hole positioning and an excellent surface finish.
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 DN65 PVC Backing Rings
- Connecting PVC pipe spools to flanged pumps, valves and instrumentation
- Tie-ins between PVC 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
