Structural Clamps

This category of clamps is designed to repair a damaged sub-sea pipeline by transferring the structural load of the damaged section onto the clamp body. The Super-Fit series is used for repairing line weakness, leak, deformation, blockage, rupture, line modifications and to increase efficiency.

Benefits

  • Sealing mechanism safe for sour gas and other corrosive materials
  • Innovative sealing energization procedure that makes installation very simple
  • Integrated body assembly for robust handling and environmental performance
