Tied Lateral Expansion Joints
Tied lateral expansion joints (commonly referred to as articulated expansion joints) incorporate two ‘sets’ of convoluted stainless steel membranes joined together by a central connecting spool or pipe and are designed to absorb relatively large amounts of lateral travel (these units can also be supplied to offer small amounts of axial travel).
Tied Lateral Expansion Joints are ‘restrained’ expansion joints, with the integral tie-bar assembly designed to restrain the pressure thrust generated when the unit is operating under pressure, thus relatively light anchors and guides may be utilised as only minimal forces are transferred to the adjacent pipe work installation. Tied lateral expansion joints are often utilised on pipe systems carrying steam, water, oil and condensate, or to accommodate building and storage tank settlement.
