Success Stories
INJECTION PIPELINE INSTALLATION: REINFORCEMENT AND REPAIR
Problems
A high pressure water injection line has external corrosion on girth welds due to corrosion under shrink sleeves.
Conditions
Removal of the shrink sleeves revealed external corrosion ranging from 20% to 50% wall loss.
Solution
Apply Syntho-Steel™ epoxy mastic to corroded area and wrap with the calculated number of layers of Syntho-Glass®XT. This solution brings the HPI line pressure capability back to that of a pristine pipe.
Result
Thirty joints ultimately repaired with each, then subsequently pressure tested with no failure. Normal operations resumed at 2300 psi (158 bar)
