ABSTRACT:
A branch apparatus for a pipe and a branch method using the same connect a branch pipe installed to a place requiring a fluid such as a gas, a chemical substance and water to a main pipe through which the fluid flows. The branch apparatus for a pipe and the branch method using the same make a laying depth of the main pipe be identical with that of the branch pipe by horizontally installing a branch apparatus, and thus make the branch pipe receive both a low vibration and a small load from the ground. The branch apparatus includes a T-type pipe having a horizontal pipe whose both ends are opened and a vertical pipe connected to an upper part of a center of the horizontal pipe; a reinforcement plate welded to the main pipe for being welded to one end of the horizontal pipe of the T-type pipe; a flange which is welded to an upper part of the vertical pipe of the T-type pipe, and has female screw lines in a center thereof; and a plug coupled with the center of the flange.
