System for and method of sealing a flowline with a metal seal after hot tapping

Abstract:

In embodiments, a hot tap clamping system comprises a clamp which fits over and secures against a pipe, an actuator interface, an actuator operatively in communication with clamp, and a hot tap assembly. In a further embodiment, a system for sealing a flowline with a metal seal after hot tapping comprises a sealer, a hot tap drill/plug running tool, and a metal seal plug which is typically configured for use in sealing a flowline, e.g. a pipe, with a metal seal after hot tapping where the metal plug seal is inserted into the pipe and engages with and seals as a hot tap.
