The couplings designed for use with our glass process plant and pipeline components are of major importance from two main points of view.

• They must ensure that the bolt load applied to the joint is sufficient to make an effective seal whilst not inducing undue stress in the glass.
• They must be totally reliable in all service conditions on the inner walls.

This chapter of the catalogue covers not only the necessary couplings to join glass equipments and pipeline components together but also the couplings needed to join glass to another materials. For glass plants installed in relatively corrosive environments and added advantage is the availability of couplings constructed form various materials including stainless steel and plastic.
