ABSTRACT:
A tool adapted for inserting and removing pitot tubes or other sensing elements through a hot tap into a fluid conveying pipeline is mounted to the side of the hot tap. A drive tube is slidably inserted into a protective enclosing tube, with the enclosing tube being attached to the hot tap and the drive tube being attached to the sensing element. Rotation of a threaded drive shaft causes a threaded bushing connected to the drive tube to move upward and downward within the enclosing tube depending on the direction of rotation. Downward movement of the drive tube inserts the sensing element into the pipeline through the hot tap and upward movement of the drive tube removes the sensing element from the hot tap.
