A Continued Vision of Integrity Improvement
When the space race began it became clear there was a realistic need for light-weight durable materials. NASA turned to composites to put a man on the moon. This technology was both sturdy enough and light enough to be propelled into space. A group of individuals envisioned the capabilities of this proven composite technology on pipelines worldwide thus the Clock Spring Company, LP was born. Originally Clock Spring turned to composites for a crack arrestor product. These crack arrestors are typically used on very high pressure CO2 lines, enriched natural gas pipelines, and various other applications where the threat of long running cracks exist. It soon became apparent there was a need for a permanent pipeline repair system to be developed. Clock Spring rose to the challenge and began to develop derivative products.
In 1987, the Gas Research Institute assembled a distinguished team of pipeline professionals and research organizations for the purpose of formulating and directing a comprehensive program to verify the effectiveness, permanency, and durability of a composite repair system. The performance requirement for a repair which “permanently restores the serviceability of the pipe” necessitated long-term testing under worst-case conditions. A decade long program was developed. The GRI conducted extensive burst tests, stress rupture tests, field validations, cathodic shielding tests, and cathodic disbondment tests. This evidence was submitted to the DOT as evidence of a complete, accurate, and verifiable technical information. The DOT changed their language in the year 2000 to recognize Clock Spring as a permanent repair. The GRI program remains the most thorough and trusted composite testing program ever conducted.
