ABSTRACT:
A thermal insulation device for insulating irregularly shaped objects such as pipe flanges and fittings is described which comprises a flexible thermal insulation member of specified dimensions adhered to a cover sheet and also containing detection means for detecting leakage from the flange or fitting to be insulated. The device is removably attached to the flange or fitting by securing means. The device thus provides efficient thermal insulation of pipe flanges, fittings and the like while permitting easy and prompt detection of any leakage from within the structure.
