PURPOSE: A spray pipe for spraying liquid phase chemical is provided to selectively replace various connection pipes according to circumference of a work place. CONSTITUTION: A spray pipe for spraying liquid phase chemical comprises a connection member which is connected to a flexible hose supplying contraction air; a connection pipe controlling the length of a spray pipe by being inserted into one end of the hose connection member; a nozzle housing(13a) which accommodates a spray nozzle by being connected to the end of the connection pipe; a nozzle pipe(14) which is coupled to the nozzle housing; and a chemical transfer pipe(15) which penetrates through the inside of the nozzle pipe, connection pipe, and hose connection member. The connection member is coupled and fixed to the connection pipe by being fixed with screws which inserted into one end of the connection pipe to penetrates through the inside thereof. The nozzle pipe comprises a spray hole(14f) which has a screw part for connection with the nozzle pipe, and sprays chemical powder out, from the center hole of an air-guiding cone in the center of one side. The nozzle pipe comprises the air-guiding cone, a chemical control valve which is located in a connection part with the connection pipe, and a valve handle(13b). |
