For cased boreholes from a depth of 35 m and a diameter greater than 1500 mm, LEFFER HD has drill pipes in its portfolio that meet the requirements for particularly large drilling depths. Reinforced pipe connectors with backlash-free, conical pipe screws and greater wall thicknesses reduce wear on the drill pipe connectors and also ensure reliable transmission of vertical forces and torque.<\/p>\n\n\n\n
