To theoretically analyze and confirm the repair performance of band-shaped repair materials with active water-stop function against common circular hole and crack defects in water supply pipelines, instruments including electronic tensile testing machines were utilized to measure and analyze their physical and chemical properties, such as shear bond strength on different substrates, water absorption rate after immersion, mass loss rate, and mechanical properties of the materials post immersion. Furthermore, for circular hole and crack defects, the repair effect was characterized by comparing the critical water-stop pressure of the repaired pipelines, and the repair parameters including the overlap width of the repair layer, the width of the repair material, the number of repair layers, the length of the repair layer extending beyond the defect, the shape and size of the pipeline leak orifice, and the water pressure during live-water repair were determined. To validate the physical strength of water-activated materials applied for pipeline leak repair, electronic tensile testing machines and other instruments were used to test the tensile strength and tear resistance of the materials, and their physical and chemical properties including water absorption rate after immersion and mass loss rate were analyzed. The characterization capability of intelligent sleeves for leak signals was elaborated based on the data from static pressure tests and dynamic water flow tests.
