Clock Spring

CAN (Offshore) Limited has been appointed as Authorised Installers of Clock SpringŪ products. The Clock SpringŪ sleeve is a specially developed high strength composite material. Its unique coil-shape allows the Clock Spring to wrap tightly around pipe of virtually of any size. Applied with a fast-curing, yet incredibly strong adhesive, it forms a composite wrap which actually exceeds the yield strength of the original pipe.

Clock SpringŪ is used to repair corrosion defects with up to 80% metal loss, as well as mechanical and third party damage. The repair is stronger than the pristine pipe allowing the pipeline to be returned to service at 100% of its maximum allowable operating pressure.

Features & Advantages

• Can be applied on Operational Lines thus no product loss or production downtime
• No Hot Work involved and no environmental risks
• Repairs can be made by a two man team
• All hoop stresses in the defect are shared with the composite making the repaired section stronger than original pipeline.
• All external corrosion growth is eliminated
• Does not shield Cathodic protection
• No post inspection required
• Repairs up to 80% wall thickness loss with no pressure limitation
• Clock SpringŪ is invisible to MFL tools so Internal corrosion growth can be monitored
