Double Hinged Expansion Joints

Double Hinged Expansion Joints are designed to absorb lateral and angular movements in only one plane.

This special type of expansion joint is made up of two bellows joined together by a linking pipe and fitted with welding ends or flanges plus a double articulated system. The hinge mechanisms are designed to contain pressure thrust. 

Double Hinged Expansion Joints can absorb Lateral and Angular movement in one plane. The double hinged expansion joint contains pressure thrust forces with no main anchors required and minimum guiding required

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 load..

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 ..
