In any piping system adequate provision must be made for expansion and contraction due to temperature changes. Distortion, mis-alignment, vibration and many directional movements are some additional requirements to be taken caer in the piping system.
Today metallic bellows expansion joints are the most modern economic means to absorb movements in the piping system as also to meet the requirement for mis-alignment, distortion, vibration etc. In contrast to other devices such as pipe loops, and slip joints, bellows type expansion joints accomodate movement in several directions, eliminate costly maintenance and require less space.
Stanflex multiply bellows are the result of years of experience. The conept of the multiply construction led to the development of the highly flexible stanflex bellows. The multiply bellows have the combined strength of many layers to withstand the internal pressure while they still retain flexibility as well as movement capacity of the individual thin ply.
