CRACK ON PIPE ELBOW AND VALVES
In a semiconductor plant, a 4” natural gas pipeline is leaking at the pipe elbow and valve connections. It is necessary to stop the leak as soon as possible without performing hot works and while the plant is in operation.
SealXpert repair putty and Seal Stic epoxy was applied onto the pipe elbow to stop the leak and reinforce the pipeline. Next, Wrap Seal fiberglass tape was applied over the repaired surface to increase the pipe wall thickness.
