In many high-pressure applications, designers often prefer to use hub-type (Grayloc) connectors for pipe-to-pipe connections. The hubs save both weight and space compared to ANSI Class 1500 or 2500 flanges. In standard hub-type designs, the heating medium must be transferred across the connector via external jumpovers.

Hub-type connectors are also available in flow-through designs which allow the heating medium to be directly transferred from one pipe spool to another. No jumpovers required.
