Clock Spring BlackDiamond® is ideal for transmission pipeline integrity repairs involving field bends, deformation, metal loss, and crack-like anomalies. It is an engineered, wet applied repair system featuring proprietary carbon fiber cloth applied with a two-part epoxy and a high modulus filler material. It is available in multiple kit sizes for any diameter pipe, in any configuration. 

FEATURES:

• 50-year DOT accepted repair system for transmission pipelines.
• ASME PCC-2 and ISO 24817 compliant.
• Repair kits will restore pipelines to MAOP on up to 80 percent wall loss, mechanical damage, mill defects, and axial flaws.
• Removes need for pressure reduction or pipeline shutdown.
• Zero performance loss validation on 10 year test program.
• Excellent adhesion to virtually any substrate.
• Can be applied on field bends and girth welds.
• Used in all environments, in over 60 countries.
• Can be used in road and river crossings, and air to soil transitions.
• High Temperature and Subsea systems available.
• BlackDiamond kits are installed quickly and efficiently by certified installers.
• Remote training classes available for Operator Qualification.
• Simple marking band system makes repairs visible to in-line inspections tools.
• Robust low profile repairs with high strength and low creep.
• Easy to install and cure.

The Clock Spring Leak Stopper™ works fast! It is designed for quick and safe temporary leak containment, with an optimized strapping method that achieves efficient and secure composite placement using teeth that are part of the band. Using the low-profile buckles makes executing repairs less cumbersome and time consuming than alternative methods and produces a finished profile that is only 1 inch thick.

Leak Stopper™ is ideal for onshore oil and gas pipelines, refineries and petrochemical plants, and municipal water and gas distribution lines, replacing bulky bolt-on products that require more time to install and introduce greater risk. Installing the Clock Spring Leak Stopper™ is simple. The process requires a trained installer using a gauged clamping device to tension the specialized band securely over the leak with a low-profile buckle. The result is a reliable and durable temporary repair within seconds. Once the Leak Stopper™ is installed and the leak is stopped, Clock Spring engineers can design an engineered composite solution as an overwrap to prolong the life of the piping system.

BENEFITS:

• Rapid repair process prevents environmental exposure to hydrocarbons within seconds
• Teeth designed into the tightening band improve strength, safety, and repair speed
• Low-profile repair simplifies installation and composite overwrap application
• Not diameter specific – The band can be used for various pipe diameters
• Third-party verification of materials performance in aged samples
• Certified SGS tensile strength certificate
