Every system has its limits! Originally developed for the DN150 / 6" - DN315 / 12" range, this milling robot can be used in the linered pipe of that dimensions up to 87° bends (also 2x 45°). The device can also be used in DN125 / 4" pipes, but there up to max. 45° and depending on the liner used! In order to avoid possible snagging of the robot when retracting during operations, we recommend URGENTLY to remove larger wrinkle formations, especially on the inside of bends, with the cutter already when driving over the lined pipeline. If you would also like to convince yourself of the excellent sheet travel of our system, we would be happy to arrange a product demonstration with you!
