<P>PROBLEM TO BE SOLVED: To provide an inorganic fiber corrugated heat insulation plate for elbow, which is improved in work efficiency and heat insulation effect to an elbow part of an air conditioning duct (spiral duct) major diameter pipe (cold/hot water pipe, steam pipe), and composed of each split piece. <P>SOLUTION: Each split piece obtained by expanding the inorganic fiber corrugated heat insulating board of a circumferential length matched to the elbow part is connected to the outer surface of the elbow part by a surface covering member and fitted along the elbow part, and the joint parts thereof are adhered by the adhesive tape of the surface covering material, whereby firm and close heat insulation of the elbow part can be performed without clearance. <P>COPYRIGHT: (C)2008,JPO&INPIT |
