Product Description

An expansion joint refers to a flexible component that effectively compensates for axial deformation. For instance, expansion joints welded onto the shell of a fixed tube sheet heat exchanger possess high axial flexibility and readily deform. They compensate for thermal expansion differences between the tubes and shell caused by varying wall temperatures, thereby reducing axial loads on both. This minimizes thermal stress differences in the tubes, tube sheet, and shell, preventing strength failure, buckling failure, and tube pull-out failure. Expansion joints come in various types, with common structures including corrugated, ring-welded, and clamp-type designs. Corrugated expansion joints are the most widely used, while ring-welded types are only suitable for atmospheric or low-pressure applications.

Expansion joints are also commonly referred to as compensators or expansion joints. They consist of a corrugated tube (an elastic element) as the primary working component, along with end tubes, brackets, flanges, guide tubes, and other accessories. Expansion joints are flexible structures installed on vessel shells or pipelines to compensate for additional stresses caused by temperature differences and mechanical vibrations. They utilize the effective expansion and contraction of the bellows to absorb dimensional changes in pipelines, ducts, or vessels resulting from thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements in these components. They are also employed for noise reduction, vibration damping, and in heating systems. To prevent deformation or failure of heating pipelines due to thermal elongation or temperature stresses during heating, compensators must be installed to offset thermal expansion. This reduces wall stresses and forces exerted on valves or support structures.

As a freely expandable elastic compensating element, expansion joints offer advantages such as reliable operation, excellent performance, and compact structure. They are widely used in chemical, metallurgical, and nuclear industries. Expansion joints used on vessels come in various forms. Regarding corrugation shape, U-shaped expansion joints are the most widely applied, followed by Ω-shaped and C-shaped types. Expansion joints used on pipelines, in terms of structural compensation, are further classified into universal, pressure-balanced, hinged, and universal joint types.
