ClockSpring|NRI

ClockSpring|NRI Bands are a pipeline reinforcement system and repair sleeve for high-pressure transmission pipelines.  Standard configuration is a continuous coil of pre-tensioned e-glass fiberglass for reinforcement.

THE SYSTEM INCLUDES FEATURES SUCH AS:

• 50-year DOT accepted repair system for high pressure transmission pipelines

• ASME PCC-2 and ISO 24817 compliant

• Repair sleeve will restore the pipeline to full strength on up to 80 percent wall loss as well as assorted mechanical damage and mill defects.

• Available in 4” through 56” diameter kits, each kit will include a coil, filler, adhesive and tools • Can be applied on bends and girth welds

• Removes the need for pressure reduction or pipeline shutdown during installation

• Meets standards of internationally recognized repair codes

• Used in all environments, in over 75 countries

• Marine Adhesive allows for underwater repair application

• High Temperature system available

• Clock Spring|NRI repair sleeves are installed quickly and efficiently by certified installers.

• Simple marking band system makes repairs visible to in-line inspections tools

The Clock Spring|NRI 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|NRI 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|NRI 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

Atlas™ is a high strength, high stiffness carbon fiber solution for on-site repair of piping structures. Atlas™ HT is for use on piping structures with operating temperatures of up to 450°F. Atlas™ is designed for repairs requiring strain reduction due to dynamic loading conditions and is most commonly used for pipelines and piping systems that have suffered from corrosion or third party damages.
