Abstract : Tests on protective coating materials for steel pipe are a continuing effort to evaluate their relative resistance to the erosive forces produced by silt-, sand-, and gravel-laden water. Exposures simulated by the test conditions sometimes occur in siphon pipes having earth-lined canals upstream. Additional tests were conducted to evaluate the erosion resistance of epoxy mortars, epoxy coal-tar paints, and some of the newer synthetic resin materials. Other tests were made to evaluate the performance of sandfilled conventional paints and to ascertain the erosion effect on unlined steel pipe and an asbestos-cement pipe. Erosion resistance of the materials is compared with coal-tar enamel which is one of two materials generally specified for lining buried steel pipe. Erosion resistance is, of course, only one of many factors considered in the selection of a protective lining for steel pipe. (Author)
