Impact-Protective Coating For Plastic Pipe
US Patent:
3948294, Apr 6, 1976
Filed:
Sep 16, 1974
Appl. No.:
5/506609
Inventors:
Gerald M. Magarian - Long Beach CA
Robert A. Thompson - Cerritos CA
Robert A. Thompson - Cerritos CA
Assignee:
Ameron, Inc. - Monterey Park CA
International Classification:
F16L 914
US Classification:
138141
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.
