Abstract
Disclosed is a method, system and apparatus for use in remotely and internally tapping a conduit. The method is performed, at least partially, by an automatic mechanism or robot configured to effectively perform the tasks and various steps of the method. The method includes the steps of: (a) lining a conduit with a liner; and (b) inserting an automatic mechanism into an internal portion of the liner, wherein the automatic mechanism (i) locates a service tap connection point; and (ii) at least partially engages a fitting device within an internal surface of the service tap entry portion, thereby providing fluid communication between a service tap internal passageway and an internal portion of the liner. An automatic mechanism, a fitting device and an insert element are also disclosed.
