REINFORCEKiT® 4D, Dent, gouges and leak – Europe
High-performance composite repair solution for pipe reinforcement
Overview
Onshore transfer 24" pipeline was damaged by an excavator which caused both one large dent and a leak. The pipeline reinforcement was performed in April 2014 by 3X ENGINEERING (3X) team.
Results
On this special case 3X ENGINEERING demonstrated once again its efficiency and competency in damaged pipeline repairs. Our on-site pro-active support allowed a restarting of the pipeline without removing the damaged pipe.

SCOPE OF WORK
The whole repair was done according to 3X finite elements analysis. The pipe was fully flooded with water. The leak sealing was done by using arc welding. Before composite wrappring, surface preparation was performed using sandblasting.
Wrapping process was then performed according to the 3 main steps described below:
- F3X8 filler was applied at welding area. The dent and its gouges were also filled in with this filler.
- 3X resin was then applied on the entire prepared surface of the pipe.
- Kevlar tape was impregnated with 3X resin and was wrapped helically with 50% tape overlap. Twenty (20) layers of composite were necessary to reinforce the pipeline. Curing time of 72 hours was done prior to hydrotest at 10-bar pressure.
