ENGINEERED
EXPANSION JOINTS FOR
FLUID CATALYTIC CRACKING UNIT (FCCU)

Belman has successfully engineered and manufactured four Expansion Joints for a Spanish oil refinery. They will be installed in the refinery’s fluid catalytic cracking unit (FCCU).

 

Design

Belman engineered the Expansion Joints for fluid catalytic cracking (FCCU) in accordance with the client’s specifications, KBR specifications and the ASME B31.3:2010 design code. The solution required two hinged expansion joints and two gimbal expansion joints. Belman supported the client with expert advice from the early engineering stage and also through the preparation of a comprehensive design report. This report contained more than sixty pages, including stress analysis of the external hardware, thermal calculation, bellows calculations and more. In addition, Belman also attended the kick off meetings at the client premises.

The Expansion Joints for fluid catalytic cracking (FCCU) were designed as two-ply testable bellows with additional stainless steel hoses to be connected to the test port. This ensured that the maintenance during service would be easier to perform. Furthermore, in accordance with the specification a special zinc coating system was used.
