DNV-compliant structural clamp delivering a robust permanent repair solution for all pipeline defects, for sweet and sour service.

Long-term pipeline integrity secured for all pipeline repair scenarios, including dynamic axial, compression and torsion loads.

FEATURES

  • Pipeline repair for all defects including full pipeline break
  • Twin radial and longitudinal seals – enabling integrity testing without pressurising existing defects
  • Seals configured to avoid contact between clamp grips and pipeline media – suitable for H2S and CO2 service conditions.
  • Radial seals and structural grippers energised by activation flange to ensure correct stress and long-term structural integrity
  • Designed to cope with full pipeline dimensional tolerances including ovality
  • Positive grip/seal activation – removes routine inspection requirements and maintenance costs
  • Eliminates need for grout and enables clamp re-use should a pipeline be decommissioned
  • Reliable installation process for right-first-time repair
  • 30-year design life
