Expansion joints are designed to safely absorb movement caused by thermal expansion and contraction of piping in piping systems.
Without them, pipes would not be able to withstand the forces exerted upon them and entire pipework systems would fail. When correctly selected and installed expansion joints act to prolong the service life of the pipework system and reduce the risk of downtime and for additional maintenance and repair.
Expansion joints - sometimes called expansion bellows, flexible joints or Expansion joint - are devices that comprise of a flexible element known as the bellows membrane that is fitted to end connections that are best suited to the pipework they are to be installed in.
Expansion joints are used in all kinds of different sectors and in a huge range of different industrial contexts. Essentially, wherever there is a need to control pipework movement expansion joints are required.
Expansion joint failure can occur for various reasons, but experience shows that failures falls into several distinct categories.
Compensator reliability is by the design, manufacture, installation and operation and management and other aspects of the composition. Reliability should also be considered from these aspects.
Pipe expansion joints are also known as compensators, as they 'compensate' for the thermal movement.
Expansion joints are required in large ducted air systems to allow fixed pieces of piping to be largely free of stress as thermal expansion occurs.
Metal pipe expansion joints can withstand the design temperatures, pressures, as well as, provide the capacity necessary to absorb thermal growth of the piping system.
Stainless steel bellows expansion joint is the compensating elements installed in pipelines, machines and containers, we often call it compensator.
Stainless steel bellows expansion joint mainly has three basic movement types: axial movement, lateral movement and angular movement.
Expansion joints are devices containing a bellows membrane that are designed to absorb dimensional changes, such as those that occur due to thermal expansion or contraction of a pipeline, duct or vessel.
Each grade is typically made to a specific Brinell hardness value, as opposed to other steels that are made with tensile strength and toughness in mind.
