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
