High Temperature Catofin Unit Expansion Joints

Furnished for IBN Sinamtbe Facility

The lbn Sina MTBE Plant in Jubail, Saudi Arabia used Catofin Unit Technology provided by Lummus. Detail engineering was performed by Fluor Daniel in Houston, TX Senior Flexonics Pathway provided the high temperature hinge and gimbal expansion joints necessary to handle the large movements generated by the high temperature Catofin process.

The high temperature hinge and gimbal expansion joints incorporated floating ring technology for attachment of the hinge hardware to the pipe avoiding high stresses caused by differential thermal growth between the pipe and rings. All the bellows were ply testable design to insure maximum reliability in service. The high temperature expansion joints used “hot shell” construction with bellows designed to operate near the media temperatures. A total of 34 expansion joints of various designs were included in the work scope.
