Bellows expansion joint
TLDR
In this article, an internal cylindrical weir or sleeve is used to define an inner flushing chamber adjacent the expansion bellows wherein connections are provided on the exterior wall of the expansion joint body to allow the admission of a chemical solution or treating fluid directly onto the inside surface of the bellows from an external connection to the expansion joints.Abstract:
A novel bellows expansion joint design and method of preventing stress corrosion cracking incorporates an internal cylindrical weir or sleeve which defines an inner flushing chamber adjacent the expansion bellows wherein connections are provided on the exterior wall of the expansion joint body to allow the admission of a chemical solution or treating fluid directly onto the inside surface of the bellows from an external connection to the expansion joint. In addition, a further connection is provided to a second flushing chamber surrounding the exterior of the bellows so that a similar solution may be admitted and allowed to overflow from an upper portion of the chamber.read more
