发明名称 Installation tool for plastic coated pipe
摘要 A tool and method for joining together two sections of plastic coated rigid metal pipe without applying pressure to the plastic coating to avoid damage thereto. The tool has a tubular body with an internally threaded open end which is loosely threaded onto one end of a section of pipe. A friction plate mounted on a threaded shaft within the body is advanced into pressure engagement with the peripheral end edge of the pipe to rotate the pipe through the frictional contact therebetween upon rotation of the body by a tool. The friction plate is loosely mounted on the shaft to compensate for irregularities in the end edge of the pipe. Rotating the tubular body in the opposite direction will disengage the friction plate from contacting the end edge of the pipe without rotating the pipe.
