8 pagesDate: June 10, 2020


The article considers the problem of rehabilitation of utility pipelines of public water supply systems. The article analyzes the results of the experiments for determining the strength characteristics of Scotchkote® 2400 protective corrosion resistant coating of pipes, that were carried out in the laboratory of the Water Supply and Sanitation Department of the Moscow State University of Civil Engineering with Instron 3345 electromechanical tensile testing machine. The effectiveness of Scotchkote® 2400 liner relative to restoring and improving the strength and hydraulic characteristics of worn water pipelines. The author comes to the conclusion that Scotchkote® 2400 liner is a substantial alternative to cement-sand and other internal coatings, since in many respects it surpasses them owing to the ability of colmatage sealing of large diameter holes; high wear resistance; smooth surface; ability to endure high hydraulic pressures. The coating does not overlap service connections and only slightly reduces the diameter of the restored pipelines. Based on the conducted research the characteristics of Scotchkote® 2400 liner spraying technology are presented compared to the basic methods of trenchless pipeline reconstruction.

Mathematical processing of the results of experimental studies of the physical and mechanical characteristics of Scotchkote® 2400 liner is given. As a result of the studies, the calculated values ​​of the protective coating thicknesses for partially worn and worn out pipelines have been obtained and recommended.
