ADAPTOR BACKING FLANGES
Adaptor backing flanges are used to couple a glass end to the flange having different bolt configuration. These flanges are made of cast iron and are supplied with inserts. These are particularly used to fit a glass equipment on a non-glass equipment like Glass-lined Reactor etc. Adaptor backing flanges are generally supplied undrilled. However, if specified, these can be supplied drilled as per "Table E", "Table F" and "ASA150" standards.
