Abstract: The invention relates to a permanent method of repairing leaking, damaged, or weakened pipe by grit blasting the pipe (10), followed by wrapping it with a fiber reinforced composite material (12), then installing two half oversized steel sleeves (14). After that the non-gaseous matter is removed by fresh water and compressed air or inert gas. An epoxy or cementitious grout or combination of both is finally injected into annular chamber 20 of the sleeves through pre-installed inlet port (16) and outlet port (18). The epoxy or cementitious is then allowed to cure. The terminal end of the steel sleeves may be sealed using a pair end flanges (32) matingly securable to a pair of terminator bodies (45).
Abstract: An apparatus to seal terminal ends of the two half oversized sleeves, positionable on the external circumferential side of affected riser pipes. The apparatus comprises of a pair of flange bodies integral to the two half oversized sleeves and a pair of terminator bodies. Each flange body includes a semi-circular collar with a plurality of bores and a semi-circular lip. The terminator body includes a semi-circular collar with a plurality of bores and a semi-circular recess structured and configured to receive the respective semi-circular lip. Two semi-circular graphite strips are introducible into the semi-circular recess. The terminator body is secured against the flange body by tightening of nuts and bolts introduced between the bores in the flange body and the terminator body.
