BIMETALLIC FLANGES, SERIES-EBMF25
Transcript of BIMETALLIC FLANGES, SERIES-EBMF25
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.
