Backing Flanges Manufacturer SPECIALIZED BACKING FLANGES MANUFACTURER, DI BACKUP FLANGE DIMENSIONS, GALVANIZED BACKING FLANGE. Marcel Piping Projects Supply PVT LTD is renowned Manufacturers, Stockists, Suppliers, and Exporters of Backing Ring Flange in India. A backing ring is a circular metal ring, with holes around the perimeter, used in pairs to bolt two HDPE pipe spools together. This allows lengths of PE pipe to be disconnected and re-connected, for inspection, replacement or relocation. The internal diameter of the backing ring should always be slightly larger than the outside diameter of the HDPE pipe. These metal backing rings allow the two ends of a pipe to be joined with bolts. Also known as back up plates, backing rings hold the pipeline tightly to a valve or fitting and are often required for high-pressure pipe applications. Our backing flanges include options for use with stub ends and angle face rings. We carry back-up flanges constructed of ductile iron, galvanized ductile iron or stainless steel, Carbon Steel, in a wide range of sizes preferred by agriculture and water works industries. we are largely exporting broad array of our in stock Carbon Steel Backing Flange, PN16 PN10 Backing Flange, ANSI 150 Backing Flange, Galvanized Backing Flange, Loose Backing Flange, MS Backing Flange, Split Backing Flange, Weld Neck Backing Flange, DI Backup Flange, Stainless Steel Backup Flange, Convoluted Flange/ Backup Ring to USA, UK, Qatar, Mexico, Nigeria, Saudi Arabia, Kuwait, Iran, Kazakhstan, Bahrain, Vietnam, Indonesia, Norway, Ghana, Colombia, Azerbaijan, Libya. Backing rings are specified and used for the following reasons: Improves installation time to compensate for poor alignment of valves etc. Especially when retrofitting into metallic pipelines. Is usually cheaper than full face flanges especially when dealing with 400NB and above even more so at 16bar+ It negates bending effects especially when connecting to raised face flanges.
