Clock Spring|NRI – Composite Wraps
ClockSpring|NRI is the world’s leading manufacturer of permanent and temporary Composite Pipeline Repair solutions. The recent merger of Clock Spring and NRI companies provides PipeServ access to the full suite of highly engineered composite wraps – from upstream gathering or subsea lines to midstream large-diameter lines, tanks, terminals, and process piping. The new portfolio comes with the most extensive testing data in the industry and over 30 years of proven track record.
Our composite solutions address pipeline anomalies from metal loss and small deformations to large deformations, crack/crack-like features, as well as damage to process piping working in the range of -58ºF to 730ºF (-50ºC to 388ºC).
ClockSpring|NRI pipe repair systems are engineered in accordance with Australian and International Standards (AS 2885, ASME PCC2, ISO 24817, and ASTM) as a “permanent repair system” for gas and liquid pipelines.
