Universal expansion joints The universal expansion joints consist of two bellows. They are designed to compensate axial and lateral deflection as well as minor misalignments during installation. They are mainly designed to absorb level displacements (relative motions of tanks etc.) During installation, it is important only one expansion joint to be positioned between two anchor points. No pipe weight must rest upon the expansion joint which must be properly guided in a defined direction, by pipe guides installed adjacent to the expansion joint. Type UFS Description: Expansion joint with two bellows and welded on flanges. Technical characteristics (dimensions in mm): The nominal diameter range is DN40-DN1700. The working pressure range varies between 2bar & 40bar. There is a variation of the axial and the lateral movement, depending on the nominal diameter and the working pressure. Type UW Description: Expansion joint with two bellows and weld ends. Technical characteristics: According to the technical characteristics of Type UFS.
