Victaulic® High Pressure Rigid Coupling Style HP-70

Style HP-70 is designed with a heavy housing for high pressure service. The housing key is wider than standard and the coupling housing is designed to clamp the bottom of the groove, thus providing an essentially rigid joint. To achieve this rigidity it is necessary to torque the nuts on sizes 2 – 4”/50 – 100 mm to 60 – 80 ft. lbs./80 – 110 Nm. The nuts on the 14 and 16”/350 and 400 mm sizes are torqued to 600 and 700 ft. lbs./810 and 950 Nm, respectively. All other sizes must be bolted securely metal-to-metal.

HP-70 will not allow linear or angular movement and is useful for valve connections and other points where rigidity is required. The coupling is provided with plated bolts and nuts and standard C-cross section gasket.
