<p><P>PROBLEM TO BE SOLVED: To provide a heat insulation hose of an intended length having connection port parts at both ends easily and surely by unwinding a long rolled heat insulation hose at a work site. <P>SOLUTION: In the heat insulation hose, a long synthetic resin pipe 10 is formed by connecting a plurality of short synthetic resin pipes 11 which are about 50 cm-1 m long provided with a large diameter connection port part 12 at an end and a small diameter connection port 13 at the other end by sequentially inserting and fitting the small diameter connection port part 13 to the large diameter port part 12 in a manner capable of being pulled out, and this long synthetic resin pipe 10 is coated by a foaming synthetic resin heat insulating coating material 20. A foaming synthetic resin heat insulating coating material part coating a connection part of the large connection port part 12 and the small diameter connection port part 13 in a part of a predetermined length from one end is divided from a cutting line 21 arranged at the part and thus the heat insulating hose in the intended length can be provided by separating the large connection port part 12 and the small diameter connection port part 13 at the part from each other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
