摘要： A pipe threading arrangement includes a launch body (13) and a parachute (15) within tube (12). The parachute is launched into pipe (2) via slide valve (1) and brings with it a threading cable (19). At a remote location within the pipe (2) the parachute is stopped by a catch arm (8) with associated catch finger (5). The parachute is deflated and retrieved, together with the threading cable, via the slide valve into the catch body (4).

摘要： A replacement pipe is installed within an existing service pipe (1) by first advancing a sealing means (6,8) along the existing pipe to a position adjacent its junction with a main pipe (2), then deploying the sealing means to seal against the inner surface of the existing pipe) in the example shown, by pumping sealant (10) into the space between the seal body (6) and the pipe (1), and subsequently advancing the replacement pipe along the existing pipe. The space between the two pipes is then filled with sealant and finally the sealing means is opened, in the example shown by withdrawing a guide rod (5) and its collar (7) on which the sealing means was advanced into position.
