Abstract
A pipe repair assembly for sealing leaks in pipelines that transmit oil, chemicals, steam and the like, is disclosed. The assembly is in the form of a two-part sleeve which forms an enclosure or box over a section of leaking pipe. The sleeve includes a pre-fitted sealing jacket to provide a snug fit over the pipe contour. Optionally, the assembly may have a channel or groove transverse to the longitudinal axis of the sleeve and spaced inwardly of the ends of the sleeves for receiving a floating metal ring and a ring of sealant material. The floating ring, sealant ring and sealing jacket are all compressed when bolts connecting the two parts of the sleeve are secured.
