CLAMSHELL BELLOWS

Clamshell bellows provide a very effective solution when a quick and unplanned replacement of the bellows is needed. Clamshell bellows are two-pieces expansion joints that are welded together on-site. They can be introduced retrospectively when the existing bellows lose their ability to contain pressure. The purpose of clamshell bellows is to provide a very quick remedial solution with the least disruption to the operation of the pipe system. The use of clamshell bellows invariably yields huge cost savings when compared against the cost of the manufacture and fitting of a completely new expansion joint. They can be designed as either temporary or permanent solution and as an over-sized or same-sized clamshell bellows.
