United States Patent | 3,612,082 |
Bates | October 12, 1971 |
An apparatus for connecting a service line to a main line while fluid is flowing through the main line. The apparatus includes a mandrel which holds a shaped charge. When the mandrel is brought into close proximity to the main line and detonated, the wall of the main line is perforated by the explosive action of the shaped charge to thereby establish flow communication between the main line and a valve means. This action enables a lateral, or service line to be connected to the valve means without disconnecting the flow of fluid through the main line.
