The main purpose of the rubber expansion joint’s design is to replace or exchange the frequently disastrous effects of these stresses with its naturally low rigidity or spring rate. This ability to absorb varying thermal or exterior movements in rigid piping systems is what makes this design function so crucial.
Top 4 rubber expansion joint designs
-
Expansion joints made of all rubber
For better lateral mobility, this kind has two flexible arch parts linked by a straight piece. The axial thermal motions from neighbouring pipe runs can be effectively absorbed by this single-unit configuration.
At times, the spool-type body is built with full rubber connectors, a premium leak-proof tube, numerous layers of high-strength tire cord, high tensile steel support, a fully integrated cover, and galvanised retention rings.
-
Rubber expansion joints for door hinges
This system is composed of two hinge plates that are joined by pins and fastened to the expansion joint’s internal or external hardware to encourage and isolate rotational movement in one plane. For the inside pressure thrust forces of the system, the hinge component must be developed.
To absorb significant lateral shifts in a single plane, these can be utilised in groups of two or three. For absorbing significant axial thermal motions from a nearby pipeline, this configuration works well.
-
Expansion Joints for Gimbal Rubber
The two-plane angular rotation is made easier and more isolated by this design. A common gimbal ring and two pairs of hinge plates are joined by pins in this system, which is attached to either the internal or external hardware of the expansion joint. The system’s internal pressure thrust forces must be taken into account while designing the gimbal assembly. To absorb significant lateral movements in several planes, they can be employed singly or in pairs with a single hinge design. Large vertical thermal movements from nearby pipe runs can be effectively absorbed by this configuration since it is adequately built.
-
Rubber expansion joints with in-line pressure balancing
As long as the pressure thrust forces are continually self-contained, this kind offers the sole practical method for directly absorbing significant axial thermal motions. Commonly employed when the support structure or nearby equipment has load constraints, this design comprises tie devices linking the main joint segments to the opposite balancing joint section. The body is frequently made of a single piece of rubber with full rubber flanges, an excellent leak-proof tube, numerous layers of high-strength tire cord, high-tension steel reinforcement, a seamless cover, and galvanised retention rings.
