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.
More information
The life of the expansion joints varies with the design, storage conditions, installation practices, application, and service. Appropriately timed inspections, repairs, and/or replacement of critical joints will ensure the reliable operation of the associated equipment and of the whole plant.
Premature or unexpected failure of the expansion joints and emergencies can be avoided carrying on-site scheduled inspections. On-site Inspections will provide valuable information about the conditions of the Expansion Joints and will allow the plant to take appropriate actions in due time.
If required, a site-specific erection plan is developed during one or more pre-construction conferences and site inspections involving the customer, the contractor, and others such as the project engineer.
