High Pressure
Style 1101HP
General Rubber’s Style 1101HP rubber expansion joints are designed for higher pressure applications. The standard spool type body is reinforced with additional layers of high-strength tire cord and high tensile steel reinforcements. The construction includes full rubber flanges, a high-grade leak-proof tube, a seamless cover and hot dip galvanized steel retaining rings. Additionally, they are designed to 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. This 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.
