CHARACTERISTICS
– 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’’

APPROACH:
– 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
