FCC Expansion Joints for European Refinery

MACOGA FCC Expansion Joints are engineered to meet the toughest FCC Reactor and Regenerator operating conditions and find application in Spent Catalyst, Regenerated, Catalyst, Recirculating Catalyst, Cooled Catalyst and Flue Gas Lines.

On this occasion we have successfully designed, manufactured, tested and delivered two high-tech FCC Expansion Joints for one of the largest Refineries in Europe.
