Abstract

Metallic bellows are manufacturing expansion joints commonly used in aerospace, chemical plants, power system, heat exchangers, automotive vehicle parts, piping system, petrochemical plant, refineries, etc., which are subjected to high temperature, pressure and corrosive environment. Bellows are special structures that require high strength as well as good flexibility. Most industrial piping system often suffer excessive deformation, displacement, heat expansion, vibration, and other causes which are responsible for the failure. During service, the bellows are subjected to compression, tension, bending loads and cyclic loads. Failure of bellows also occurs because of improper design. There is need to review the causes for such failures, hence the present paper was intended to study the works reported by various researches on expansion joints.Keywords: Expansion joints, metal bellow, Expansion Joint Manufacturer’s Association (EJMA)Cite this ArticlePavani G, Rao CM, Siva Prasad K.
