PURPOSE:To attain to enhance the detection accuracy of the leakage of water by judging the leakage of water by the blotch of a coloring material, by adhering a tape prepared by printing, coating or impregnating paper or a fiber with a water-soluble coloring material to the joint part of piping. CONSTITUTION:A water leakage detecting tape 1 prepared by printing, coating or impregnating paper or a fiber with a water-soluble coloring material is adhered to the outer peripheral surface of the joint part of pipe members 2, 3 formed by clamping both tube members 2, 3 by a bolt 5 in such a state that a packing 4 is interposed between both tube members 2, 3. The adhesion of the tape 1 is performed by preliminarily applying an adhesive such as a size to the peripheral edges of the back surface of the tape 1 over the entire periphery thereof. In order to easily discriminate the blotting of the tape 1, a proper picture pattern or line is displayed on the surface of the tape by ink or a paint. |
