|Length of repair||800 mm|
|Pipe Transport||Natural Gas|
|Pressure Load||55 Bar|
|Type of Defect||Girth Weld Defect caused Pipe Deformity|
Cause of Pipeline Welding Damage
External Corrosion was present as well as a physical deformity caused by a pipe girth welding defect. This caused leaking of natural gas which also affected the transport and overall pressure of the pipelines.
Onshore Pipeline Restore Challenges Presented
The challenge presented was with application of the material to a 30-inch diameter pipe carrying a total pressure load of 55 bars. Prior to application the pipe had to be clearly inspected to properly identify the deformity. It also had to be properly calculated to make sure that the pipe system would not lose pressure due to lacking proper hold.
ProAssure Wrap Application Details
The site of the damages was clearly identified, evened out and cleaned. The protective layer of paint was also stripped along with the corrosion marks. Everything was made sure that no particulate matter or left-over corrosive materials were present. The pipes were prepared using mild abrasives to remove the paint and corrosion while sanding was necessary to even out the welding deformities present. The site was then dried and prepared before being given an application of ProAssure Wrap on the affected pipes.
