Fiber, metal and rubber-cord expansion joints

Bellow expansion joints are devices, consisting of bellow and connection elements, able to absorb or balance relative movements, arising in sealed structures.  At that, expansion joint is able to transfer liquids and gases.

At present, use of bellow axial expansion joints is a modern way to extend lifespan of pipeline systems. Expansion joints allow to eliminate various deformations, that take plane in pipelines because of constant temperature drops, pressure drops and vibrations.

Pipes without expansion joints can undergo such unintended consequences as change of pipe length, at thermal expansion \ contraction of pipe metal, this can lead to pipeline tear. Accidents on pipelines lead to system catastrophes in economical, ecological and social sphere. That is why, close attention is paid to issues of pipelines reliability, enterprises are constantly searching optimal solutions of technical safety of pipeline systems.
