Abration of heavy-duty coated steel pipes due to littoral drift was studiedexperimentally and theoretically. Since steel pipes coated with anti-abrationurethane are very lower in abration rate than steel pipes, they are thought tobe suitable for use in coastal zone with severe sand transport. Abration rateis nearly proportional to collision energy of sand particle. Sand collisionenergy is related with the ratio of particle size to pipe diameter.
