摘要：A method and apparatus for removing a novel type of coupler from a coatedjoint of pipe. The coupler joins two pipes together during a coating operation and alsoprotects the ends of the pipe from application of the coating. The coupler puller utilizesan elongated telescoping arm having clamp structure at one end for grasping thecoupler and then pulling it relative to the joint of pipe. The arm is mounted for rotationabout a horizontal axis and, when necessary, the arm can be reciprocated in a verticalplane to fracture the coating and thus loosen the coupler. The arm is also mounted forrotation in a horizontal plane so that once the coupler is removed from the pipe the armcan be swung through an arc of 180 DEG to deposit the coupler at a point removed fromthe area of the coated pipe.
