Pipe-coating apparatus

Claim 1

Apparatus for coating pipe comprising: a support tiltable from a first attitude to a second attitude, means for feeding elongated sections of pipe which are open at both ends to said support, receiving means for predeterminately locating a pipe section on said support when said support is in said first attitude, power-operated means for tilting said support from said first and said second attitude to position a pipe section disposed on said receiving means with its longitudinal axis oblique to the horizontal, power means for rotating said pipe about its longitudinal axis when disposed oblique to the horizontal, means for flowing coating material into the upper end of said pipe when disposed oblique to the horizontal as it is rotated to cause part of said coating material to become coated onto the inside surface of the wall of said pipe as the coating material flows through the pipe and in a manner whereby part of the coating material flows out of the lower end of the pipe, means located at the lower end of said pipe for receiving coating material from the lower end of the pipe and means for recirculating said received coating material to said means for flowing coating material into the upper end of said pipe, and automatic control means operative after a predetermined layer of said coating material becomes coated on the inside wall of a section of pipe disposed on said support for terminating the flow of coating material and controlling operation of said means for tilting said pipe to dispose said pipe horizontally whereby the coated pipe may be removed from said support.
