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 Flanges are a circuitous raw materials ring, with hole around the border, used in couplets to bolt two HDPE pipe spools together. This allows lengths of PE pipe to be dissociated Andre-connected, for examination, replacement or relocation. The internal radius of the backing ring should always be slightly larger than the outside radius of the HDPE pipe. These raw material backing rings allow the two ends of a pipe to be joined with bolts. Also known as back upward plates, backing rings hold the piping tightly to a valve or fittings and are frequently needed for high- pressure pipe applications.

Our backing flanges include options for use with stub end and angle face rings. We carry back up flange constructed of galvanized ductile iron, ductile iron, stainless steel, Carbon Steel in a wide range of size 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.
