3150 Series Compact Expansion Joint


308/311 series expansion joints

The Keflex™ 3150 Series compact Expansion Joint is designed to meet applications that require pressure ratings up to 150 PSI in a shorter length. This is achieved using 3 or 4 plies of heavier gauge stainless steel than is used in our lower pressure rated products. The 3150 series is available for pipe sizes from 2″ up to 12″, as a bellows only component ready for your fabrication, or a fully welded Expansion Joint. These bellows are ideal for OEM’s or repair facilities looking to add desired connections or to simply weld the bellows in place for your application. Keflex™ can also create ready to install custom assemblies using these standard bellows and then installing to customer specification flanges or any other type of connection. Contact us for additional details on custom assemblies utilizing the 3150 Series Bellows.
