Abstract

After removal of a damaged pipe section, the repair can be carried out without the aid of a diving bell, by preparing both ends of the remaining undamaged pipe. A metal support strip is welded into the top half of the pipe bore leaving the strip protruding from the pipe face. A metal support strip is then welded to the bottom half pipe periphery, leaving a similar amount protruding from the pipe face. A short flanged pipe section of identical I.
