Abstract: An interlock pipe joint includes a first and second tubular member. In some embodiments, an interrupted thread box and pin make up the interlock pipe joint. In other embodiments, a stepped interrupted thread box and pin make up the interlock pipe joint. In other embodiments, a twist-lock box and pin make up the interlock pipe joint. In some embodiments, an external or internal bushing is provided. In a method of operation, the first tubular member is inserted into the second tubular member by an axial insertion followed by a rotation to lock the pipe joint.

Abstract: An apparatus and associated methods for a pipe doping apparatus is disclosed. 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. The automated pipe doping apparatus may include an ejector coupled to the dope manifold, where the ejector positioned to supply a fixed volume of pipe dope from the dope manifold to a dope distribution line. The automated pipe doping apparatus may also include a pipe dope applicator, the pipe dope applicator fluidly coupled to the dope distribution line positioned to deposit pipe dope on a threaded connection.
