The primary purpose of Universal Bellows is to accept large amount of lateral deflections which in fact is a function of the amount of angulations each bellows can absorb and the distance between the two bellows. The length of the center spool piece can be adjusted so as to increase or decrease the lateral deflection capability.flexican also designs and supplies Universal Bellows with or without tie rods, which connects the ends of the unit to each other and restrains the pressure thrust load. The number of tie rods to be provided around the circumference of the expansion joint depends on the application, for instance two tie rods are provided 180 degrees apart which enables the expansion joint to bend or deflect angularly and laterally. Similarly three or more tie rods are provided equally by pressure thrust and in such cases only lateral deflections are possible without any significant forces being applied by the adjacent piping.

Hinged Bellows, either Axial or Universal type, are designed to absorb angular rotation in one plane only by the use of a pair of pins through hinge plates attached to the expansion bellows.Hinged Expansion Bellows should be used in sets of 2 or 3 to function properly. Hinged Bellows are normally prevented by their design from deflecting axially, either in extension or compression. The hinge mechanism is usually designed to accept full pressure thrust and also shear loads such as from the weight of the adjacent piping, can be accepted by these type of expansion joints thereby doing away with provision of additional supports and anchors.

Axial Expansion Joint is the simplest form of expansion joint. A flexible element either with flange end or Butt Weld End to absorb any combination of three basic movements. i.e. Axial movement, Lateral deflection and Angular rotation along the axis of the pipe line.Axial Bellows do not control the movement of the pipes and in case the piping analysis indicate that the expansion joint should accept axial compression, then in that case the piping must be guided and constrained so that only that movement occurs.

Ideally selected based on all types of flow directions and dust load. However, depending upon the flow direction sleeve orientation and types of sleeve will be modified.Fabric life is enhanced since the fabric is never exposed to the medium temperature and is always protected by insulation bolster and sleeve.The fabric could be easily replaced in case of any emergency exigencies like change in process parameters.

Double Bellows are the type of expansion joints where two bellows are provided. The use of these expansion joints are for applications where absorption of high thermal expansion or contraction of straight pipe runs is desired. The joint can be located near the center of the run, and proper anchors and guides has to be provided. Each Bellows in this case act as a single expansion joint.
