Clock Spring Pipe & Pipeline Repair Systems
 
1.Clock Spring comprises (1) a patented, high-strength, unidirectional composite structure
2.Patented, fast curing, high performance two-part adhesive system.
3.Extremely high compressive strength, proprietary load transferring component. 
Once installed, the three elements bond together to form extraordinarily strong and durable repair as demonstrated by the results of the following hydrostat test.
 

  10” diameter pipe with a machined flat bottom defect of 8” length, 3” width and 80% metal loss.
During the hydrostatic test, the defect failed at 70 bar pressure.
     
 

         

       
A Clock spring was installed on an identical defect.
During the hydrostatic test, the pipe burst at 200 bar.
       

 

The Clock Spring and defect is stronger than the pristine pipe.
