<<There are two methods in common use for providing for expansion
in pipelines. One method involves the use of expansion bends and the other the use of expansion joints.>>

Applying Expansion Joints To Your System Mercer Rubber Co.

<<Elastomeric expansion joints serve many functions in modern
piping systems. They offer significant advantages over alternatives such as metallic expansion joints or expansion loops. Unfortunately, rubber expansion joints are often misapplied. Design and maintenance of an optimal system requires an understanding of both the basic functions and the requirements of the piping system. The main purposes of an elastomeric expansion joint are to reduce noise and vibration, and accept thermal movements. They reduce noise and vibration by creating a discontinuity between pipe materials. Noise and vibration theory explain that a rotating piece of equipment such as a centrifugal pump will create noise and vibration via its unbalanced force.>> Received on Thu Aug 16 13:56:00 2001
