The Slurryflex SJE Reducer Expansion Joint comes in either a concentric or eccentric configuration. It is used to join a pump’s discharge to a pipeline with a different diameter.

A concentric reducer has a cone shape that puts it on the same axis as the connecting pipe. Meanwhile, an eccentric reducer has one flat side that is parallel to the adjoining pipework.

This reducer expansion joint is designed to accommodate pipe misalignment, thermal expansion, noise, and vibration. It’s suitable for suction and discharge duty involving the transfer of abrasive slurries, tailings, sand and gravel, and may also be specified for hydrocarbons, chemicals, and acids.

All of our Slurryflex expansion joints are custom made in Australia from premium materials. Tell us about your application and we’ll help you choose the right materials, size, length, and end connections.
