The repair of corroded or damaged pipelines using composite repair systems is growing, especially in the oil and gas industries. Composites have proved themselves as a strong and durable material, capable of providing the qualities required when performing critical repairs. Numerous field trials, in-house testing, and third party testing has demonstrated that StrongBack System possesses those performance qualities, and as such, has been successfully used on many pipelines for repairing external corrosion and mechanical damage.
StrongBack Sleeve ® is a low cost composite system for use in repair and reinforcement of existing mechanical systems, structures and piping. Furnished factory-impregnated with proprietary 22-77 resin system. It is odorless and non-flammable. Cured StrongBack Tape® is a durable, high strength material, impervious to fuels, most chemicals and solvents. It permanently bonds to a wide variety of surfaces such as metals, composites, concrete, plastics and wood. Certified to ANSI/NFS Standard 61.
StrongBack Sleeve ® is comprised of a proprietary polyurethane formula and custom-woven biaxial glass fiber. As a biaxial fabric, it provides strength in two directions, hoop and transverse. For piping, hoop strength is critical, but handling the transverse load is also important. Strength in two directions can be equally important to many other types of reinforcement that StrongBack Tape® is designed to handle. For these reasons, biaxial fabric was a sound choice.

StrongBack Tape® is ready to apply, right out of the bag and cures by the way of a chemical reaction with field-applied water. This offers considerable advantages over conventional cloth-resin systems in that there is no resin measuring, mixing, spreading, solvents or dripping polymer mess. [ More Applications ]
The material installation requires use of a base primer material to provide a proper bond to the surface being repaired. StrongBack Tape Tape ® is then installed, utilizing water as the activator. The material can be installed circumferentially around the object, or spiraled at an angle to provide uniform coverage over long distances. After installation, a unique method is used to compress and consolidate the composite.

Handling
StrongBack Sleeve® is shipped in a sealed protective bag to protect it from atmospheric moisture. Because it cures with the application of water (and air humidity), care must be taken in handling the sealed bags to prevent puncturing or scuffing them which would cause the product to cure in the bag. Once the bag and the StrongBack Tape® is exposed to humidity in the air, it will begin to cure and will gel with 60minutes. Therefore, work must be well planned prior to opening the bag. StrongBack Tape® requires no other special handling or application procedures. This resin is slightly irritating to certain sensitive people; it will give off a small amount of carbon dioxide vapor while curing; and the cures resin is permanent and very difficult to remove, so gloves, safety glasses and other personnel protective equipment appropriate for the task must be used.
Design and Application Instructions
Design guidelines and application notes for various applications are available from the factory
Shelf Life
StrongBack Tape® has a shelf life of 12 months in its original package. Store in cool, dry place, but do not refrigerate.
