Adjustable Dismantling Joints are used for joining two flange ends for the following : -
* to create gaps/space in flanged pipelines.
* to fill up/adjust gaps/space in flanged pipelines.
* can absorb limited vibration/expansions contractions.
A Flanged Spigot of same nominal bore as that of adjoining pipelines slides inside a flanged spigot barrel of higher diameter to create dismantling space.
