Clamshell bellows

A clamshell bellows is a temporary repair solution for damaged expansion joints.

MACOGA Clamshell bellows is a good option where an existing expansion joint is to be repaired without cutting or opening the pipe.

Clamshell bellows is a two-piece bellow which is welded around the existing unit.The bellows is split in half longitudinally in our works. The halves are match-marked to ensure the bellows halves are aligned correctly. The clamshell is fitted accurately in position. A purge gas is set up to minimize oxidizing of the weld to ensure a good quality weld. The clamshell halves are then welded back together.

MACOGA provides skilled clamshell bellows welders to perform this welds at site. Field welds are 100 % dye penetrant tested by our qualified staff.

Your next FCCU turnaround or plant outage can benefit from the revealing information that MACOGA On-Site staff can provide. MACOGA offers a unique means to evaluate your FCCU Expansion Joints condition and equipment reliability.

Our technicians are experienced, knowledgeable engineers who have worked throughout the world in innumerable refineries.
