PURPOSE: A pipe system of a blow molding is provided to use a low-pressured air amplifier without a high-pressured compressor, to grasp easily mechanical troubles, and to improve the production efficiency of goods by simplifying an electrical control. CONSTITUTION: A pipe system of a blow molding is composed of a first speed control valve(210) connected between a first blow valve(110) and a second blow valve(120) coupled to one end of an airline(100) inserted by a predetermined air pressure, a third blow valve(130) connected to the first speed control valve and a first blow pin(310), a second speed control valve(220) linked to both a fourth blow valve(140) and a fifth blow valve(150) on the airline connected with the first and the second blow valve, a second blow pin(320) connected to the second speed control valve, a particle collecting box(190), a pressure gauge(400), a sixth blow valve(160), and a third speed control valve(230) connected to a cooling line in sequence on the airline connected to the second speed control valve, and an air amplifier(600), a seventh blow valve(170), and an eighth blow valve(180) coupled consecutively on other end of the airline.
