Before installing our STOPKiT® sealing solution, the previous solution was withdrawn. The sealing was then performed according to 3X installation procedure described below using STOPKiT® ONSHORE and referenced STON014 (suitable reference for a 14" pipe in onshore area with a maximum size defect of 25mm and up to 120 bars of pressure and 150°C).
- STOPKiT® was firstly positioned next to the leakage using specific positioner device.
- STOPKiT® was then slided to perfectly center the rubber patch over the defect.
- Once positioned over the leakage, STOPKiT® right and left screws were tightened until leaks were sealed (40 Nm max).
- Finally, STOPKiT® positioner device was removed.
The leaking defect was totally controlled and sealed.
