Abstract: PROBLEM TO BE SOLVED: To provide a heat insulating tube for hot/cold water suitable for a base material for heat insulating piping or the like and having further excellent workability.
SOLUTION: This heat insulating tube is provided with a flexible tube (1) made of synthetic resin and a heat insulating material (2) covering the outer periphery of the tube (1). The heat insulating material (2) comprises woven or non-woven fabric made of synthetic resin, and is further covered with a wrapping tape (3). On the outer periphery of the tube (1), an air layer shielded from outside is constituted. Since the thin heat insulating material (2) is covered with the thin wrapping tape (3), this structure further reduces the outer diameter and enhances degrees of freedom in terms of execution of works.
