Overview
The objective of the repair, performed in December 2023 by 3X ENGINEERING (3X) specialist was to seal online a leaking defect located on a 14" pipe transporting H2S gas. The previous repair system installed by competitor failed and 3X was called urgently to solve the problem and stop the leakage.

SCOPE OF WORK
Before installing our STOPKiT® sealing solution, the previous solution was withdrawn.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.
