RUBBER EXPANSION JOINT SUPPLIERS
Contact the DEWATER PRODUCTS rubber expansion joint suppliers on (08) 9414 6124 based in Perth, Western Australia.
Available in size 32mm to 3600mm. 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.
Australia’s Leading Suppliers of Rubber Expansion Joints
Dewater Products are Australia-based suppliers ready to deliver you any Rubber Expansion Joint with different flange classes. Material linings can be any rubber available on the market suitable for your application, and flanges can be any steel with galvanised or epoxy surface finish, or stainless steel.
Our parts can also have tie bars installed between the flanges for added strength and support when axial movement may be present in the pipeline. This will ensure the rubber will remain intact and not break by limiting the movement.
The joint is used for connecting a pump to a pipeline, as the pump will be vibrating against a fixed pipe system, the rubber expansion joint will allow for axial compression and extension, lateral offset and angular deflection.
There are two types of rubber bellows designs being spheres or spools. Sphere expansion joints are the most commonly used due to their economical cost. Spools are the more robust design with a higher cost compared with sphere joints.

Multiple configurations available
With both Sphere and Spool type rubber expansions they can be in the configuration of Single Arch, Double Arch and Triple Arch. These arches can be filled or unfilled. The filled type is ideally suited to Slurry and Sludge application so that the straight bore inside of the rubber expansion bore will remain clean and unclogged. The unfilled arch style allows great axial, lateral and angular deflection compared with the filled type, however dirt, sludge and slurry media can get caught in the gap especially at the bottom due to gravity if installed on a horizontal pipe system. Expansion bellows can also come with control units, or tie bars as they are otherwise known, these are recommended to be installed on a rubber expansion joint if there is going to be more movement in the joint than it could cope with if it didn’t have the control units fitted.
Materials of the rubber expansion joint and bellows can come in many types, different rubbers have different properties so EPDM is great for water based media, NBR is great for oil based and gas based medial, Viton is great for chemical based media and higher temperatures.
