Abstract
An energy-absorbing protective coating is bonded to the exterior of a plastic pipe. Preferably, the coating is a layer of low-cost, crushable, multicellular, inorganic particles, such as natural volcanic lightweight aggregate, expanded shale, expanded clay, pumice, slag, or furnace cinder, embedded in a thin film of plastic resin. The particles crush by breaking upon impact, which absorbs the energy of the impact and protects the pipe from damage.
