Backing Rings / Loose Flanges

Rotec logo

Backing Rings / Loose Flanges are used for easy assembly of pipes systems and tank connections. The Backing Ring (Loose Flange) and the Stub Flange form a dismountable joint for future disassembly and allow for easy alignment. Composite Backing Rings are non conductive and a good, competitive alternative for aluminium, galvanized steel, stainless steel and thermoplastic products. Conductive Backing Rings can be manufactured on request.
