ABSTRACT:
A tapping band allowing for interconnection of fluid conduits without any interruption to fluid flow includes means (1A and 1B) adapted, in use, to be disposed around a first pipe (2) and having an outlet (3) extending substantially normally therefrom, the outlet (3) in turn defining the locale intended for tapping. The outlet (3) includes a slot (9) for receiving and releasably retaining a sealing member, in the form of a valve blade (10). The arrangement is such that, once in position relative to the conduit (2), a suitable drilling means is employed for tapping into the conduit (2) via the outlet (3), with the valve means then acting to seal the outlet (3) once the tapping means has been withdrawn. A secondary conduit (20) can then be joined to conduit (2) in any known manner and, when joined, the valve blade (10) can be withdrawn from the slot (9), thereby allowing fluid to pass from conduit (2) into conduit (20).
