Coupling and Gaskets

Couplings are used to join the various components together to form the complete process pipeline and plant.

The complete coupling includes two flanges, two inserts and the necessary numbers of nuts and bolts to join them together. The couplings designed for use with glass process plant and components are important from two main points of view:

1. They must ensure that the bolt load applied to the joint is sufficient to make an effective seal whilst not inducing under stress in the glass.

2.They must be totally reliable in all service conditions.

An PTFE O-ring is usually placed between the coupling to insure proper sealing of the joint. Other components such as adaptor flange, backing flange, bellow flange, and PTFE bellows, together are used for complete interconnection of glass components.
