Patent ID: 7082960

Claim:
A pipe tapping apparatus, by which a sub-pipe branches from a main pipe through an electric heat-welding process and a tapping process is executed using a cutting drill, comprising: a base pipe, comprising: a saddle-shaped socket part to be in close contact with an upper portion of an outer surface of the main pipe to pass a fluid therein; and a bending part coupled to the saddle-shaped socket part while being in close contact with a lower portion of the outer surface of the main pipe; a coupling pipe to be coupled to the sub-pipe extending to a predetermined place in which the supplied fluid is used, with a ball valve provided in the coupling pipe to control a flow of the fluid passing through the coupling pipe; an electric heat-welding pipe to couple the coupling pipe to the base pipe, the electric heat-welding pipe comprising a first heating wire which is provided in the electric heat-welding pipe to weld the electric heat-welding pipe to the base pipe, and a second heating wire which is provided in the electric heat-welding pipe to integrate the coupling pipe with the electric heat-welding pipe; and a first positioning unit removably coupled to an end of the coupling pipe, with a first through hole provided in a center of the first positioning unit, thus guiding a process of tapping the main pipe using the cutting drill passing through the first through hole of the first positioning unit.
