Flange Connections

Mill-Pro offers a range of flange assemblies (flange adapter c/w backing flange) and standard PE flange adapters and loose backing flanges with various ring option sizes and materials to suit all applications.

Full Face assemblies – designed so the connecting equipment ID and the PE pipe ID match as closely as possible, with stepping limited to ≤10%.

Standard assemblies – standard size flange adapters and backing rings used for PE pipe to PE pipe flanged joints, may create a step when connecting to equipment DN in sizes ≥ DN250. 

Reducing assemblies – lowest cost option for sizes ≥ DN250, uses a reducer to align the connecting equipment DN and PE pipe ID, creates a large step at the flange face.
