Transmission pipelines represent the most common type of repair which utilizes Clock Spring products. These repairs are made on high pressure and low pressure pipelines. These repairs are made on both external ( typically a permanent repair) and on internal ( sometimes a temporary repair). Documented approvals are in place for many national regulatory authorities and also for most company specific approval systems. Clock Spring repairs have been made approximately 80 countries. The system has been commercially available since 1993. The installed base of repairs is large and is growing rapidly. More then 1 million coil-years of service have been successfully recorded. All standard pipe diameters have been repaired. Please see the various photographs of several representative repairs.
