A DNV-compliant structural clamp that delivers a robust and cost-effective permanent repair solution for all pipeline defects, for non-sour service applications.

Securing long-term pipeline integrity across structural repair scenarios, including axial, compression and torsion loads, efficiently and economically.

FEATURES

• Cost-effective and economical structural repair solution

• Leak repair for defects such as pin-hole, broad area metal loss or stress-induced defects, and up to full pipeline break, for non-sour service applications

• Twin radial and longitudinal seals – enhances pipeline integrity by enabling integrity testing without pressurising existing defects

• Structural grippers and seals energised by plunger (as opposed to compression only) – allows clamp design to suit upper and lower pipeline tolerance boundaries and greater clearance to pipe OD to cope with ovality and prevent seal damage

• Positive grip/seal activation – removes routine inspection requirements and potential for increased maintenance costs

• Eliminates need for grout and enables clamp reuse should a pipeline be decommissioned

• 30-year design life and permanent first-time repair
