  • Apparatus for coating pipe threads
    Patent number: 4986210
    Abstract: Apparatus for coating the endmost threaded section of a pipe with corrosion resistant powder coating material by rotating the pipe and spraying the section to be coated with electrostatically charged, air-entrained powder through two stationary nozzles, one of which is directed at the section to be coated, and the other of which is directed at the chamfered end of the pipe. To prevent overspray of the powder from contacting the pipe adjacent to the area to be coated, a pair of air nozzles are directed at the area of the pipe adjacent to the area to be coated.
