PROBLEM TO BE SOLVED: To provide a pipe insulator 10 which requires no device, fixture, submaterial or the like, and facilitates mounting work when the pipe insulator 10 is mounted onto a pipe P. SOLUTION: While a cylindrical wall part is formed in an uneven shape in which a part contacting the outer peripheral surface of a pipe P and a part separating therefrom are alternatively arranged, the uneven parts are successively formed in an axial direction of a cylinder. By so doing, a folded crease of the unevenly formed cylindrical wall part is widened, which eliminates necessity of a device, a fixture, a submaterial and work related to them. By turning the face contact into a line contact with respect to the outer peripheral surface of the pipe P, slide resistance is substantially reduced so that the mounting work onto the pipe P can be facilitated. After the mounting onto the pipe P, an air layer is formed between the pipe P and the pipe insulator 10 to exhibit heat insulation effect. As a result, the thickness of the pipe insulator can be made thinner than that of conventional one. COPYRIGHT: (C)2006,JPO&NCIPI
