The Direct Pipe® technology combines the advantages of Microtunnelling and HDD and can be applied in all ground conditions. In one step only, a Microtunnelling TBM excavates the borehole and the prefabricated pipeline is installed using a Pipe Thruster in the launch pit. This allows safe and fast installation of pipeline crossings and landfalls. A new distance world record was set in 2020 in New Zealand, where a 48” pipeline has been installed on a length of 2,021 meters. Direct Pipe® is available in diameters ranging from 24” to 60”, using a newly developed slurry jet pump system for small diameters.
