Bellows Expansion Joint: Pressure Loads, Anchors & Guides

Pressure generated loads in piping systems containing bellows are sometimes not understood. This can lead to system failures sometimes resulting in bellows failure and possible rupture even though the bellows design is adequate for the operating conditions. The purpose of this paper is to examine the bellows loads imposed on piping system and to show some methods for dealing with these loads.
