The  XZ6600 horizontal directional drill successfully completed the 1833m long crossing of the Dongxing branch line of the supporting gas pipeline of Sinopec, and the first drill in the Sinopec pipeline laying project perfectly traversed 1200m.

The construction plan of double drilling rigs to drill through is used for directional operation. The two drilling rigs must be drilled from the two ends to ensure the accuracy of direction control. In the reaming stage, the dual drilling rigs are used to rotate together to increase the torque over a long distance and provide Professional mud ratio and drilling tool transformation ensure the rationalization of various operating indicators and minimize the risk of custody.

To the industry’s surprise, the XCMG XZ6600 did not use a pipe pusher when towing the pipe. It only relied on the water suspension method to reduce the weight and friction of the custody, so that all links were closely linked, and the custody was very smooth. At present, the project has successfully hosted two drills, with an average duration of 1 month per drill.
