EXPANSION JOINTS
KINJOINTS expansion joints are used mainly to absorb dimensional changes caused by thermal movements of a pipeline.
They consist of bellows formed from a thin-walled stainless steel tube. Bellows expansion joints are preferred to other
methods of absorbing pipe movements, such as pipe loops and slip-type joints. Pipe loops are wasteful of space while slip
joints require regular maintenance. Additionally, loops and slip joints are capable of absorbing movement that is in line with
the pipe only. Bellows joints require no maintenance and allow many types of movement in a compact space.
KINJOINTS Bellows expansion joints are available in flanged, welded, grooved, or threaded ends. Internal liners to prevent
erosion of the inner surface of the bellows and the induced vibrations by the flowing fluid are available. Optional features
include tie rods to control movement and shrouds to protect the outer surface of the bellows from damage in buried
installation. Consult Kinetics for proper anchoring and guiding of pipe with expansion joints to prevent extending or buckling
of joints due to pressure thrusts.
