摘要：The invention relates to a method for providing reconnection to a ferrule (1) ofa service line via a bore (2) of the ferrule (1) from within a bore (3) of a lined host pipe (4)adapted to carry a fluid, comprising the steps of locally enlarging a bore (2 or 3) of amember of the ferrule/host pipe system (1, 4), lining the host pipe with a liner (5),locating the ferrule (11) from within the lined host pipe (4), forming a passage for fluidthrough the liner (5) to the ferrule (1), and forming a seal with the system whereby toobviate leakage of fluid between the liner and host pipe. The host pipe (4) can be a mainsuch as a water, oil or gas main, and the service line can be a branch pipe to carry saywater from the host pipe (4) into a building such as a dwelling. A standard-sized localenlargement in the ferrule/host pipe system can be formed. This thus ensures uniformityand where local enlargement of the bore of the ferrule is used, one operation can beused in whatever size of ferrule is inserted in the host pipe. Thus, it is often the case thatdifferent sizes of ferrule are used adjacent one another in a length of host pipe.
