Lateral Expansion Joints
Lateral expansion joints are mainly used in pipelines with a change in the direction of flow which results in lateral rather than axial movement.
The lateral expansion joint absorbs movement in all directions but only in one plane and to a limited degree. For absorption of larger lateral movement the optimal solution is the installation of a universal expansion joint.
Double gimbal expansion Joints with flanges
Double Gimbal Expansion Joints are designed to allow angular movement in any plane by the use of two pairs of hinges affixed to a common floating gimbal ring. The gimbal ring, hinged and pins are designed to restrain the pressure thrust due to internal pressure and shear forces. This particular metal expansion joint has two bellows and flange ends.A gimbal ring is either round or square. For round gimbals the torsional moment shall be considered and for square gimbals the ins..

Double Hinged Metal Expansion Joints - flanged
Double Hinged Expansion joints are mounted to limit the expansion joint to absorb angular and lateral movements in only one plane in the hinged metal expansion joints. Due to the hinges the expansion joint is not able to absorb axial movement. The hinge is likewise designed to protect the bellow from torsion. These movement limiters reduce the loads from the pressure thrust force and the temperature of the pipeline. The pressure thrust force from the media is in this way abso..
Double Hinged Metal Expansion Joints - welding ends
The double hinged expansion joints are made of one double bellow element fitted with welding ends plus a system of articulated supports which allow for angular movement in one plane only. The hinge mechanism is designed to accept full pressure thrust. These units do not allow axial movement however, some types of hinge systems can be provided with holes for the hinge pin that are slotted to allow limited axial displacement. These “slotted hinge” types can not resist the press..
