PURPOSE: A pipe system of a blow molding is provided to overcome the limit of air pressure by using a low and a high-speed air pressure and to maximize the production efficiency of goods by reducing curing time. CONSTITUTION: A pipe system of a blow molding is composed of a first speed control valve(210) connected to both a first blow valve(110) and a second blow valve(120) connected to one end of an airline(100) inserted by a predetermined air pressure, the first speed control valve connected to a third blow valve(130) coupled with a first blow pin(310), a fourth blow valve(140) and a second speed control valve(220) linked to a second blow pin(320) in the middle of the airline connected with the first and the second blow valve, and a particle collecting box(400), a fifth blow valve(150), and a third speed control valve(230) connected to a cooling line in sequence on the airline coupled with the second speed control valve.
