Method of hot tapping into a pipe

摘要

A hot tapping assembly for hot tapping into a multiple string configuration to obtain access to the production tubing without removing outer layers of casing, the hot tapping assembly including a hot tapping clamp and a hot tapping seal assembly. In one embodiment, the hot tapping clamp includes a clamp plate having an access bore. The clamp plate can engage with an outer surface of a pipe. In another embodiment, the hot tapping seal assembly can engage with the hot tapping clamp, and includes a hot tapping tubular that can engage with the outer surface of the pipe through the hot tapping clamp's access bore.

1. A method of hot tapping into a pipe, the method comprising:
mounting a hot tapping clamp assembly around an outer surface of a pipe, the hot tapping clamp assembly comprising a front clamp plate having a front access bore; drilling, through the front access bore, an access hole in the outer surface of the pipe to access a first internal pipe; mounting a hot tapping seal assembly to the front clamp plate, the hot tapping seal assembly comprising a hot tapping seal; contacting, through the front access bore, the hot tapping seal to an outer surface of the first internal pipe; hot tapping the outer surface of the first internal pipe through the hot tapping seal; and wherein the mounting connection between the hot tapping seal assembly and the front clamp plate creates a force to cause a seal between the hot tapping seal and the outer surface of the pipe.
