Document Type and Number:
WIPO Patent Application WO/2013/089335
Kind Code:
A1
Abstract:
Provided are a heat insulation cover for pipe material and a fabrication method therefor. The disclosed method for fabricating a heat insulation cover for pipe material comprises the following steps: a) measuring pipe material and preparing drawings for forming a mold; b) fabricating a mold having the same size and shape as the pipe material based on the drawings; c) cutting an insulation material according to the size of the mold and temporarily fixing the insulating material to the mold; d) cutting a hot wire cloth according to the size of the mold, to which the insulating material is fixed, so as to surround the outer peripheral surface of the insulating material, sewing a hot wire to the cut hot wire cloth in a zigzag shape for fabricating a heating unit, and then temporarily fixing the heating unit to the mold; e) cutting an inner skin according to the size of the mold, to which the insulation material and the heating unit are temporarily fixed, and basting the inner skin while maintaining the thickness and the shape of the insulation material; f) connecting a temperature sensor for sensing the temperature of the pipe material and connecting a lead wire for supplying power to the hot wire; and g) cutting an outer skin for covering all the insulation material that surrounds the mold, the heating unit and the inner skin and then basting the outer skin.
