18" ID X 12" ID X 14" FF Style 1101CR concentric reducing rubber expansion joint
Concentric Reducing
Style 1101CR
General Rubber's Styles 1101CR and 1201CR concentric reducing rubber expansion joints are an economical way to combine a reducing pipe fitting with an expansion joint. The two different flanged diameters have a common centerline. Additionally, they are designed to absorb large all-directional movements, reduce noise and vibration, have a cycle life in the tens of millions, compensate for misalignments, provide access to piping and equipment and relieve pipe and anchor stresses. 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, a seamless cover and hot dip galvanized steel retaining rings. The above construction, as a standalone expansion joint, represents the most cost-effective arrangement when used in rigid piping systems with main anchors (MA) and numerous guides at specific spacing. Control units can be externally or internally attached and used as limit rods for secondary restraint or as tie rods when the support structure or adjacent equipment have load limitations.
