Description
Bellows expansion joints, also known as bellows expansion joints, are devices consisting of a flexible metal bellows capable of absorbing thermal expansion, compression, or angular deflection in pipelines and systems. They are used to compensate for axial, lateral, and angular movements, providing stability to the system amidst temperature and pressure fluctuations. Bellows expansion joints are typically made from specialized materials, often stainless steel, and find wide applications in various industries where compensating for thermal expansions and contractions is essential, preventing damage to pipelines and equipment.
