G-Range Pipe Connections

Due to their efficiency, lightness and reliability, together with extreme qualities of leak tightness, the G-Range pipe connection offers significant benefits for use in industrial plant in a wide variety of applications. Although designed primarily for adverse pressure and temperature conditions, more modest applications can be considered due to ease-of-installation and assembly, particularly when compared with the alignment and tightening of standard flanges.

The G-Range pipe connection comprises: a pair of hubs for welding to the pipe (similar to a flange); a clamp set, which can be rotated around the hubs to suit the most practical positions; and a seal ring.

The seal ring is a modified cone ring giving excellent leak tightness properties under the most severe conditions of pressure and/or thermal shock. On assembly the taper joint faces compress the seal ring radially. The sealing force is provided by the stored energy in the stressed seal ring, any internal pressure intensifies the sealing action.

Using high strength alloy clamps and flush bore seal rings, minimum fluid seals areas and low make up loads are achieved allowing smaller and more compact units than flanges of equivalent pressure ratings.

High Pressure Containment
The higher the pressure, the more effective the G-Range connection becomes, as internal pressure intensifies the seal.

High Temperatures
The standard 'all-metal' seal ring is suitable for most applications - maximum temperatures are limited only by the connection materials selected.

Extreme Leak Tightness
The seals remain leak tight under the most arduous conditions of pressure, temperature and vacuum conditions, even after many thousand hours of operation.

Resistance to Pressure and Thermal Shock
Cold quench conditions and thermal cycling are the cause of most leakage problems, where conventional compressible type joints and seal materials are used. The flexibility of the seal ring compensates for this during thermal transient conditions.
