The Clock Spring® Pipe Support (PS) System provides effective protection at support or hanger locations. It can be applied quickly and easily. No special tools or training are required.
Clock Spring® PS consists of a high-strength corrosion resistant fiberglass composite sleeve, a high performance adhesive, and a filler material.
The fiberglass composite sleeve is uniquely coil-shaped and sized to wrap tightly around pipe diameters from 3/4” to 36” providing two (2) individual layers bonded together resulting in a laminate thickness of approximately 1/8”.
Clock Spring® repairs are fast, economical and easy. Since no cutting or welding is required, there are no risks to the environment, release of greenhouse gases or waste disposal problems.
It’s simply the smartest pipeline repair decision you can make!

Installation
Clock Spring Pipe Supports typically consist of two concentric wraps of the Clock Spring® composite shell. The shell is in the form of a split sleeve, with a circumference slightly smaller (0.063-inches (1.5 mm) than the pipe being protected. Each shell will fit around the pipe leaving a slight longitudinal gap. Each layer of the Pipe Support will be applied such that the longitudinal seams are staggered from the longitudinal seams of the preceding layer.
