The branch tee for sprinkler pipes includes a branch tee body () having a cylindrical shape, a first outlet () disposed on one end of the branch tee body () and connected to a pipe of a closed sprinkler head, an inlet () disposed on the branch tee body () and connected to a water supply pipe, a second outlet () disposed on the branch tee body () and connected to a pipe of an open sprinkler head, a piston valve disposed in the branch tee body () and simultaneously controlling opening and closing of each of the first outlet () and the second outlet () while moving in a longitudinal direction of the branch tee body () due to a fluid pressure difference in the branch tee body () when fire occurs, and an inner wall groove () defined in an inner wall of the branch tee body () between the piston valve and the first outlet ().
