Hinges forks placed 180° apart connected by pins. Joints connected to center spool called as double hinged.

Design to restrain pressure-thrust and other external loads.

These joints are for angular and lateral movement s in one plane/two plane.

This design is very effective with respect to pressure thrust absorption, limited guiding & intermediate anchors, prevention of torsion, support to dead weight & low forces on the pipping system.

Capable of absorbing lateral displacement in one plane restraining the pressure-thrust.
