Abstract
Embodiments of the present invention relate to a volumetric compensating annular bellows used to compensate two fluid volumes by an annular displacement. This is achieved using a bellows welded on to a tube with a varying shape radius. A bellows is arranged within the annulus and is deformable in an annular direction in response to fluid volume expansion. The bellows can be used in several oilfield applications for fluid compensation.
