Asbestos-Cement Pipe Fitting And Method For Making It
US Patent:
4027901, Jun 7, 1977
Filed:
May 24, 1976
Appl. No.:
5/689340
Inventors:
Jay S. Forni - Danville CA
International Classification:
F16L 908
US Classification:
285 55
Abstract:
A fitting for asbestos-cement pipe is welded to the end of one cement-lined iron pipe section and extends axially for receiving the end of a second pipe section. The generally cylindrical fitting includes two steps at which its diameter decreases progressively toward the inner end of the fitting. The steps and decreased-diameter areas are formed by a disclosed spin-forming method which imparts superior strength and stability. In an outer cylindrical area, positioned against the outer step, is an annular bar which, with the inner step, forms an annular recess for receiving an annular elastomeric sealing gasket. When the second, spigot-ended pipe is assembled into the fitting, its outer surface compresses the sealing gasket against the fitting recess to seal the two pipes together positively and to retain the gasket securely against the forces of positive and negative pressures.
