The metal expansion joint belongs to a compensation element.The metal expansion joint is mainly used to compensate for axial displacement and has the ability to compensate for angular displacement, but it is generally not used to compensate for angular displacement. Metal expansion bellows are compensating elements for thermal expansion and relative motion in pipes, vessels and machines. Absorption of axial, lateral, and angular displacement.
