G R T Flange

THE SPECIALITY OF G R T FLANGE IS ITS BASE GEOMETRY. THIS GEOMETRY CONSIDERABLY IMPROVES GASKET FLOW IN VERTICAL DIRECTION AND RESTRICTS FLOW IN HORIZONTAL DIRECTION. SO IT GIVES A MUCH SUPERIOR GASKET SEALING THEN THE CONVENTIONAL FLANGE.

ADVANTAGES OF G R T FLANGE

STANDARD FLANGE

IN HAZARDOUS CHEMICAL APPLICATIONS NORMALLY DUAL GASKETS ARE USED. THESE ARE OF TWO DIFFERENT RESINS, GENERALY ONE IS NITRILE AND OTHER EPDM. CHEMICAL COMPATIBILITY IS NOT IN BOTH, THUS THERE IS A COMPROMISE.

G R T FLANGE

A SINGLE LARGE GASKET WILL REPLACE DUAL GASKETS OF TWO DIFFERENT RESINS ENFORCING CONSIDERABLY CHEMICAL COMPATIBILITY, THUS ENSURING HIGHER PURITY OF DRUM CONTENT. EPDM HAS POOR FLOW CHARACTERISTICS, BUT GOOD SUPERIOR GEOMETRY CAN MAKE FLOW JUST AS IN DUAL.

ADVANTAGES OF G R T FLANGE

STANDARD FLANGE

CHEMICAL COMPATIBLITY REDUCES BECAUSE OF TWO DIFFERENT MATERIALS OF GASKETS.

G R T FLANGE

CHEMICAL COMPATIBILITY RANGE INCREASES AS YOU CAN USE EITHER A NITRILE OR AN E P D M GASKET

G R T FLANGE OFFERS COMPLETE CHEMICAL COMPATIBLITY FOR THE HAZARDOUS CHEMICAL HANDLING THAT NEEDS EXTRA PROTECTION.

• These flanges can be fitted with the same insertions dies that are used for standard ones.– No change in Tooling– No Adjustments– No Production Slowdowns

• There is no licensing fee for the Drum Manufacturer.• Superior sealing with more vertical gasket flow.• Accommodates single large gasket in place of dual

gaskets.• Thus more chemical compatibility than dual gaskets.
