BACKING RING
A backing ring is a loose metallic flange that slides over a PE flange adaptor (stub end) and provides the mechanical strength needed to create a secure bolted joint in polyethylene piping systems. It is used to connect PE pipes to other materials such as valves, hydrants, pumps, steel or ductile iron pipelines, and ensures that the joint is strong and reliable.
BACKING RING – High Pressure Resistant Flange Connection
Areas of Use:
- Water distribution and drinking water networks
- Natural gas and LPG pipelines
- Industrial liquid and gas transport lines
- Sewerage and wastewater systems
- Irrigation and agricultural piping
- Connection of PE pipes to valves, hydrants, and pumps
- Joining PE pipelines with steel or ductile iron pipelines
Advantages:
- Enables connection between PE pipes and other materials such as steel, ductile iron, valves, and pumps
- Durable and corrosion-resistant when made from stainless steel or coated metals
- Provides mechanical support for PE flange adaptors under bolt load
- Ensures strong and reliable bolted connections
- Allows easy disassembly for inspection, maintenance, or replacement
Why Choose Backing Ring?
Backing Rings (Steel flanges) are the ideal solution to guarantee both durability and tightness when HDPE systems require a transition to metal equipment. It maintains the integrity of the system even under high pressure and can be used for many years without maintenance.
