ABSTRACT:
Stainless steel foil 31 is wound spirally on the circumference of a pipe body 30 from one end to another end of the pipe body 30 to overlap itself and the periphery of the pipe body 30 is covered with the overlapped layer to give a heat insulation pipe body. The stainless steel foil 31 is wound on the circumference of the pipe body 30 from one end thereof, while ceramic particles 32 are flame sprayed to the wound part of the stainless steel foil 31 to form a ceramic particle dotted layer 33. Then on the periphery of the stainless steel foil 31 with the ceramic particle dotted layer 33 formed, a part of the stainless steel foil subsequent to one end of said stainless steel foil is wound shiftedly toward an axis direction and at the same time the newly wound stainless steel foil part is flame sprayed with ceramic particles 32 to form a ceramic particle dotted layer 33 and these steps are repeated.
