Hydraulic tube pulling units series TP
The hydraulic tube pulling units TECHNODATA type TP 10, TP 15 and type TP 30 are devices for pulling tubes out of the expanded area of the tube sheet. The unit consists of a portable hydraulic aggregate and a hydraulic pulling device, connected with a hydraulic hose pack.
The pulling devices consist of the combined expanding- and pulling cylinder and has to be completed with the needed pulling tools ( expanding sleeve, expanding mandrel and distance sleeve ).
The expanding sleeve with the expanding mandrel is inserted into the tube to be pulled.
Controlled by the hydraulic system the expanding sleeve is pressed by the expanding mandrel to the tube wall. After that the expanding piston and the pulling piston are set under pressure and the tube will be pulled out of the expanded area.
The pressure of the expanding sleeve is adjusted manually by preadjustment of the expanding mandrel and by adjusting the hydraulic working pressure.
After the pulling procedure the tools are removed to the start position and the next tube can be pulled.
