Abstract (en)

[origin: WO9945307A1] A ferrule is inserted into an opening (18) formed in a wall of a lined pipe (1, 14) such that a tubular body (4) of the ferrule extends through the opening (18) and the liner (2) is trapped between the pipe (1, 18) and a flange (5) which is supported adjacent one end of the body (4). The ferrule is transported along the interior of the lined pipe from an open end of the pipe to adjacent the opening, the position of the ferrule relative to the opening being assessed visually. A tool is inserted through the opening to engage the ferrule body which is then pulled through the opening from outside the pipe and secured in position such that the flange (5) abuts the liner (2).
