In addition, there is a problem that the position of the adhesive packing material 3 is displaced, the adhesive packing material 3 is partially protruded from the outer peripheral surface of the divided portion, and the appearance is damaged.

The present invention was made in order to solve the above-mentioned problems of the prior art. It is used for water pipes, hot water pipes, various special pipes, pipe joints, valves, etc. When it is attached to a pipe member), the adhesive packing material can be easily attached to a predetermined position of the abutting end of the heat insulating cover material, which is a dividing surface, and one set of heat insulating cover material can be integrated. It is an object of the present invention to provide a heat insulating cover for piping members that does not damage the heat.

Alternatively, the ends, which are the dividing surfaces of the pair of heat insulating cover members, can be easily butted together in a predetermined position, and the adhesive packing material can be easily attached to the predetermined positions of the end members. An object of the present invention is to provide a heat insulating cover for a piping member, which can integrate a pair of heat insulating cover materials and does not impair the appearance.
