ABSTRACT:
When a pipe confining fluid under pressure develops a leak, a selected respective pipe repair assembly is used to stop the leak, while the pipe continues trying to confine the fluid under pressure. There is no need to shut down operations. A cylinder, provided in two longitudinal sections, with one section having an opened central valve and an inner sealing gasket with a hole matching the entry of the opened central valve, is secured around the pipe and over the leaking area. During the positioning of this pipe repair assembly, a half cylindrical sleeve with an upstanding end tab, and a hole with a partial length central longitudinal opening is provided for protective initial interior placement over the sealing gasket. This tab fits into an end notch on one longitudinal section, to thereby position the hole with a partial length central longitudinal opening in horizontal alignment with the opening of the valve. As so arranged and presecured, without complete tightening, this pipe repair assembly is moved sideways along the pipe and over the leak, placing the open valve over the leak. The exiting fluid is then directed out of the valve. Thereafter, the half cylindrical sleeve is withdrawn, having completed its protection of the sealing gasket from the fluid under high pressure leaving the pipe through the leak. Then the pipe repair assembly is tightened and the valve is closed, stopping the leak.
