Restrained Rubber Expansion Joints

The selection and application of General Rubber’s advanced restrained expansion joints can be used to provide piping system flexibility while restraining pressure thrust forces and other external loads. This approach allows for an optimal design with a smaller footprint. Some of the economic benefits of using advanced restrained expansion joints include fewer guides, anchors and supports.

Advanced Restrained Rubber Expansion Joints

The selection and application of advanced restrained rubber expansion joint designs can be used for custom solutions to specific and demanding applications.

In-Line Pressure Balanced Rubber Expansion Joint is the only effective solution for directly absorbing large axial thermal movements while continuously self-restraining the pressure thrust force. this arrangement consists of tie devices inter-connecting its main joint sections to its opposing balancing joint sections. the balancing joint section needs to have twice the effective thrust area as the main joint sections in order to balance the arrangement and provide somewhat of an internal anchor location. 36” ID X 36” FF shown right.
