If a bellows is leaking or damaged, or if a bellows must be changed with a target to having the minimum downtime, this is where a clamshell should be considered.
MACOGA Clamshell bellows is the best solution when a quick and unexpected replacement of the bellow is necessary. 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.
