The Direct Pipe system is designed for pipeline applications, combining the processes of micro-tunneling and horizontal directional drilling.

Using the Direct Pipe system, says the company, a micro-tunneling machine “can both excavate a hole in a single, almost continuous work phase and simultaneously install a prefabricated pipe string.” Potential obstacles are removed by the machine’s cutting wheel and cone crusher. The force necessary for tunneling is provided by the pipe thruster, which pushes the pipeline forward with four clamping segments that hold the pipe from outside. The force is transmitted via the pipeline to the cutter head of the micro-tunneling machine.
