Style 5100H

General Rubber’s Style 5100H hinge rubber expansion joint is designed to facilitate and isolate angular rotation in one plane. The arrangement consists of a pair of hinge plates connected with pins and attached to the external or internal hardware of the expansion joint. The hinge assembly must be designed for the internal pressure thrust forces of the system. They can be used in sets of two or three to absorb large lateral movements in a single plane. This optimally designed arrangement is an effective solution for absorbing large axial thermal movements from an adjacent pipe run. Its spool type body is constructed with full rubber flanges, a high-grade leak proof-tube, multiple layers of high-strength tire cord, high tensile steel reinforcement and a seamless cover. They are commonly used when the support structure or adjacent equipment have load limitations. The economic benefits of this arrangement include a smaller system footprint with far fewer anchors and guides.
