PROVIDING EFFECTIVE INTEGRITY IMPROVEMENTS SINCE 1993

Clock Spring is a composite repair sleeve and reinforcement system uniquely designed for high-pressure transmission pipelines.

Clock Spring was verified through the most comprehensive pipeline repair study ever commissioned. The 10-year, $15 million study by the pipeline industry and conducted by the Gas Research Institute, makes the patented Clock Spring the most tested, investigated, and documented composite repair solution ever developed. Our strongest pipe repair, the Clock Spring, has been tested and proven up to 8,000 psi and is expected to last 50 years or longer, deeming it a permanent repair by regulators. The Clock Spring is used in all environments in more than 75 countries around the world.
