Metal pipe expansion joint BM-UN

roundflangeaxial

A universal expansion joint is made of two single bellows separated by a central pipe and with flanges. The main objective of this type of construction is to achieve a high capacity for absorption of axial and lateral movements. This capacity is a function of the design of the bellows and the length of the intermediate section. A longer length means greater capacity for absorption. Any possible expansion of the intermediate pipe is  also absorbed by the two bellows. Characteristics and Properties Applicable for low pressures. Absorbs large lateral and axial movements. Allows angular movements. Does not retain the force of the pressure. Must be properly anchored and guided. Does not resist the force of the pressure, and must be supported by fixed anchoring that is properly designed.
