The expansion joint is a flexible structure installed on the vessel shell or pipe in order to compensate for the additional stress caused by temperature differences and mechanical vibration. Utilizing the effective telescopicity of its working body, the bellows

Advantage:

Expansion joints (compensators) have the advantages of reliable operation, good performance, and compact structure.
 

Application areas:

Expansion joint (compensator), as a freely scalable elastic compensation element, has been widely used in chemical industry, metallurgy, nuclear energy and other departments. There are many forms of expansion joints used on containers. In terms of corrugated shape, U-shaped expansion joints are the most widely used, followed by Ω-shaped and C-shaped expansion joints. In terms of structural compensation, expansion joints used on pipelines are divided into hinge type, pressure balance type and universal joint type. It can also be used for noise reduction, vibration reduction, and heating. In order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe heats up, a compensator needs to be installed on the pipe to compensate for the thermal elongation of the pipe. This reduces the stress on the pipe wall and the force acting on the valve or bracket structure.
