IHS 1420 internal hydraulic power unit
IHP is internal hydraulic hub allows positioning of pipe-pipe, pipe-tee and pipe-flange joints. The pipe fixing is accomplished by two sets of expansion jaws controlled by a hydraulic pump. Heads can be expanded independently. IHPs are used in pipeline construction, both during prefabrication and in field work. Thanks to the special centering design it is possible to carry out a complete welding cycle without the need for graft welds and pulling the centerpiece out of the pipe. This is a particularly important feature in automatic welding. Includes manual hydraulic pump, 15 m hydraulic hose, 15 m long twist rod for pushing / pulling the center of the pipe.
