Single Metal Expansion Joints
The simplest form of expansion joint, of single bellows construction, for the purpose of absorbing any combination of the three basic movements of the pipe section in which it is installed
Double Metal Expansion Joints
A double expansion joint consists of two bellows jointed by a common connector which is anchored to some rigid part of the installation by means of an anchor base. The anchor base may be attached to the common connector either at installation or at time of manufacture. Each bellows acts as a single expansion joint and absorbs the movement of the pipe section in which it is installed independently of the other bellows. Double expansion joints should not be confused with universal expansion joints.
Internally Guided Metal Expansion Joints
An internally-guided metal expansion joint is designed to provide axial guiding within the expansion joint by incorporating a heavy internal guide sleeve, with or without the use of bearing rings. The use of an internally-guided expansion joint does not eliminate the necessity of using adequate external pipe guides nor will its use prevent bellows instability.
Swing Metal Expansion Joints
A swing metal expansion joint is one containing two bellows joined by a common connector designed to absorb lateral deflection and / or angular rotation in one plane. Pressure thrust and extraneous forces are restrained by the use of a pair of swing bars,
