    HDD drill pipe

    5-2-5hdd-tools_01

    Material use OCTG, reliable performance;

    Using a unique tool joints twice thicker molding technology;

    Transition band is smooth , which can reduce resistance through the mud;

    Thread of joints liquid nitrogen treatment, surface hardness higher, thereby pipe life is longer.
