– Misalignment angle 10° (total 20°)

    – Designed to accomodate high loads

    – Swivel effect for bolt holes alignment

    – Back seal tests via annulus test port

    – Static metal / metal sealing by tightenning the bolts on intented connecting angle (locks the ball into the housing)

    – Self energized internal metal sealing

    – Sealing area insensitive to externally applied loads

  • Field installation procedure

‘’8’’ #1500 bolt tensionning distribution’’


    – Full design, calculation & FEA available as per applicable design codes.

    – FEA verification under environmental pipeline loads, where strength, sealing capability, bolt capacity and fatigue resistance are assessed
