Bimetallic flanges are used in water, gas and sanitary applica�ons for connec�ng copper tubes. They prevent accelerated corrosion and deteriora�on in the piping system due to galvanic and stray current.

·Bimetallic flange- a composite of 3 pieces; consists Carbon Steel ASTM

A105 Forged Backing Flange epoxy coated, brass insert and ABS sleeve.

·Backing flange BS EN 1092-1 PN25.

·Brass Insert is suitable for brazing copper tube to BS EN 1057.

·ABS sleeve is a thermoplas�c polymer separates the to pieces

(Backing flange & Brass insert) preven�ng an electric current from passing.
