Abstract: An apparatus and associated methods for an automated pipe doping apparatus. The apparatus may include a pump fluidly coupled to a reservoir and a dope manifold, the pump positioned to pump pipe dope from the reservoir to the dope manifold; an ejector coupled to the dope manifold, the ejector positioned to supply a fixed volume of pipe dope from the dope manifold to a dope distribution line; and a pipe dope applicator, the pipe dope applicator fluidly coupled to the dope distribution line positioned to deposit pipe dope on a threaded connection. In some embodiments, the pipe dope applicator may be a fan-pattern nozzle. In other embodiments, the pipe dope applicator may be a mold-type applicator. In other embodiments, the pipe dope applicator may be a brush-type applicator.
