Erosion Studies of Pipe Lining Materials - Fifth Progress Report

摘要

This is the fifth report on laboratory tests to evaluate the erosion resistance of the inner surface of water-bearing pipe. Erosion resistance is defined as the resistance to the wearing effect produced by abrasive particles such as would be encountered in steel pipe carrying sand or sand- and gravel-laden water. Erosive conditions are simulated by rotating a lined pipe containing a sand-water or gravel-water slurry. Coal-tar enamel has good erosion resistance and is used as the standard for comparing other materials. Seventeen RPM pipe liners, concrete, steel, synthetic and natural rubber sheet, PVC, polyethylene, and ABS pipe had better erosion resistance than coal-tar enamel; four RPM liners, three RTRP liners, and one vinyl resin liner for asbestos-cement pipe were less resistant. Results from four previous progress reports are included.
