Rubber expansion joints (Fig. 16.69) are flexible joints or connectors made from elastomers with metallic reinforcement to provide stress relief in a piping system due to thermal changes. Rubber expansion joints can absorb vibration and shocks extremely well. This type of expansion joint …

At the same time, expansion joints allow nearly force-and torque-free connection of pipes to sensitive fittings, appliances and equipment (e.g. to turbine nozzles). Moreover, expansion joints serve as assembly aids for pipe elements such as valves, where they are used as dismantling pieces or couplings. Overview Expansion Joints Type Design

The purpose of Rubber Expansion Joints: Rubber Expansion Joints, also known as expansion bellows, are used in pipelines to allow flexibility, expansion and vibration between steel pipework and a pump. Any mechanical device will move and vibrate, and can cause stresses along a pipeline, that's where our rubber bellows come in.

Type 40 is a rubber expansion joint that is only vacuum-resistant to a small degree, so a suitable vacuum supporting ring should be used on underpressure.
