ABSTRACT:
This invention is a new device for installing press fit couplings to join steel pipelines. This apparatus is a joining press which fits inside the pipes to be joined and grabs them on their inside surfaces. It then pulls the pipes together, forcing the pipe ends into the coupling. The invention is comprised of two hydraulically operated grippers to grip the pipe and a hydraulically operated cylinder to pull the pipes together. The entire press is controlled using only two hydraulic lines. The grippers can be retracted and the apparatus moved within the pipeline from one joint to the next.
