Axial extension joints are the least difficult and most practical joint. It is utilized where little warm developments exist. The prime point of preference of pivotal extension metal bellows is, the bearing of the stream is bidirectional alongside their minimal size. Axial Expansion Joints are generally made in SS304L, SS316L, SS316Ti and SS321. If there should arise an occurrence of extraordinary prerequisites they can be made in Inconel and other nickel based combinations.
Axial expansion Joints should be installed co-axially with the pipes centerline. The purpose of this bellows is to compensate axial movements. With the existence of axial movements desired cyclic life can be achieved. If incase there exist other movements like angular or lateral this will affect the cyclic life of Bellows. Generally there expansion joints are used between straight pipes where movement is parallel to the centerline of pipe line.
In case if the expansion/contraction rate is higher than the bellows capacity 2 Bellows with a center foot in between can be used. There 2 bellows are placed between the center of the pipes so that the axial movements from each ends of pipe can be absorbed by the respective bellows. One should note in case of cryogenic application the pipe expansion joint will be stretched as the piping system will contract.
The definition of an expansion joint, which is also known as a movement joint, is a joint application of the expansion or thermal movement of a part. Expansion joints, by the Association of Expansion Joint Manufacturers, Inc. (EJMA), meet the quality control standards established by the organization. EJMA, formed for the first time in 1955, is the standard setting organization for expansion boards and has been published by member manufacturers since 1958.
