FREEZING PREVENTION PIPE AND FREEZING PREVENTION METHOD
To provide a freezing prevention pipe and a freezing prevention method, that are low cost and can prevent a water supply pipe from freezing even in an extremely low temperature environment.SOLUTION: A freezing prevention pipe 1 comprises: a water supply pipe 2 made of resin; a cylindrical resin foamed body 3 that covers an outer peripheral surface of the water supply pipe 2; and an exterior pipe 4 made of resin that covers the outer peripheral surface of the resin foamed body 3, wherein a foaming ratio of the resin foamed body 3 is 20 to 50 times, the resin foamed body 3 is in close contact with the outer peripheral surface of the water supply pipe 2 and the inner peripheral surface of the exterior pipe 4 due to a press-fit structure, the resin foamed body 3 is a polystyrene foamed body, and the exterior pipe 4 is made of polyvinyl chloride.SELECTED DRAWING: Figure 1
【課題】低コストで、かつ、極低温環境下であっても水道管の凍結を防止できる凍結防止管および凍結防止方法を提供する。【解決手段】凍結防止管１は、樹脂製の水道管２と、水道管２の外周面を覆う円筒状の樹脂発泡体３と、樹脂発泡体３の外周面を覆う樹脂製の外装管４とを有し、樹脂発泡体３の発泡倍率が２０～５０倍であり、樹脂発泡体３は、圧入構造により水道管２の外周面および外装管４の内周面に密着しており、樹脂発泡体３がポリスチレン発泡体であり、外装管４がポリ塩化ビニル製である。【選択図】図１
