55 inch double gimbal pipe expansion joint for a reactor overhead line
Product description
The gimbal expansion joint is basically the same as the hinge type, except that instead of being limited to deflection in only one plane, it can accept bending or angulation in any plane. It contains two sets of hinge pins or pivots, the axis of each set perpendicular to the other. Each set of pins is connected to each other with a central gimbal ring, in much the same way that a universal joint on an automobile works.

This unit provides the same type of restraint and resistance to axial forces, such as the pressure thrust, and to shear forces as the hinge type.
Installation
-
Inspect for damage during shipment, i.e., dents, broken hardware, water marks on carton, etc.
-
Store in clean dry area where it will not be exposed to heavy traffic or damaging environment.
-
Use only designated lifting lugs.
-
Make the piping systems fit the expansion joint. By stretching, compressing, or offsetting the joint to fit the piping, the joint may be over stressed when the system is in service.
-
It is good practice to leave one flange loose until the expansion joint has been fitted into position. Make necessary adjustment of loose flange before welding.
-
Install joint with arrow pointing in the direction of flow.
-
Install single Van stone liners, pointing in the direction of flow. Be sure to install a gasket between the mating flange and liner.
-
With telescoping Van stone liners, install the smallest I.D. liner pointing in the direction of flow.
-
Remove all shipping devices after the installation is complete and before any pressure test of the fully installed system.
-
Remove any foreign material that may have become lodged between the convolutions.
-
Refer to EJMA Standards for proper guide spacing and anchor recommendations.
