RADCOFLEX Australia, leader and innovator in the design and manufacture of flexible hoses and expansion joints, presents its Metal Bellows Expansion Joints, designed to be fitted into a pipeline to absorb movements in and forces exerted on the pipeline.

These metal joints consist of a metal bellows element with flanges or pipe weld ends fitted to facilitate the bolting or welding of the joint into a pipeline. The bellows element is a metal cylinder into which circumferential convolutions (corrugations) are formed to create a flexible seal. These convolutions flex when the joint is subjected to forces within the piping system, generally thermal.

The number of convolutions in the bellows depends upon the amount of movement the bellows must accommodate or the force that must be used to accomplish this deflection. Pressure thrust forces are required to be absorbed by other devices attached to the bellows or adjoining pipework, including anchors, hinges, gimbal rings, or tie (control) rods.

A metal bellows expansion joint can be fabricated to accommodate axial, lateral or angular movements. Of the three, angular movement is the least severe on the bellows element, with lateral the most severe. Control devices can be attached to control the direction and amounts of movement that the expansion joint achieves.
