Abstract

A pipe doping system for applying pipe dope to the external threads of a pin end member may comprise a pump fluidly coupled to a dope-containing 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 and positioned to supply a fixed volume of pipe dope from the dope manifold to a dope distribution line; a dope applicator, the dope applicator fluidly coupled to a dope distribution line positioned to deposit pipe dope on the external threads, the dope applicator being located apart from the ejector and including a nozzle positioned to receive a flow of pipe dope from the dope distribution line and apply the pipe dope onto the threaded connection. The system may include a power source to increase the pressure of the pipe dope as it is dispensed by the ejector.
