Patent
·
OSTI ID:6594068
A method and apparatus are described for sealing leaks which occur at the flanged connections of pipelines. A wire is wrapped about the upper surface of the flange connecting bolts to fill the gap between the flanges and above the bolts. An injection valve is installed for relieving pressure from inside the gap while the wire is being wrapped and for injecting a sealant to the interior of the gap beneath the wire wrap. A sealant is injected beneath the wire wrap to fill the gap and to stop the leak, combining with the wire wrap to provide a permanent repair for the leak. (6 claims)
