    API Reg DTH Drill Pipe Hdd Drill Rod For Blast Hole Drilling 1000mm - 9000mm


    Description of API Reg DTH Drill Pipe DTH Drill Rod For Blast Hole Drilling1000mm ~ 9000mm


    DTH Drill rod is made of high quality material detected by spectrograph, impact and tension test.
    With fully digitized processing line introduced from Japan with integral heat treatment equipment
    Anti adhesion thread with nitrogen treatment on surface make it easier for handling.
    Metallography detection, hardness test, magnaflux inspection, ultrasonic flaw detection, tensile test and impact test ensure products quality.
    Length: 1, 000mm ~ 9, 000mm;
    Diameter: 76mm (3") ~ 146mm (5-3/4");
    Wall Thickness: 5.5mm ~ 8mm;
    Connection Thread: 2 3/8", 2-7/8", 3-1/2", 4 1/2" API Reg. Or API IF Thread.


    Raw materials:


    We choose the best steel tubes in the market to manufacture our rods and pipes. Spot check will be conducted after the steel tubes delivered to company. We will make sure the compositions and specifications match the inspection report form the suppliers.


    Thread opening process:


    Accuracy of threads will determine the use effects and life time of drill rod and casings.
    CNC latches and form cutter are used in thread opening processing to minimize error made by anthropic factors.

    Heat treatment control:


    Heat treatment will greatly improve the material strength and increase the thread wear life of the rods and casings. We conduct either tru-wall or both ends heat treatment to the tube body. After heat treatment, strength, hardness, straightness and concentricity of the treated tubes will be tested in our lab.


    Additional thread treatment:


    Surface of the threads will be cleaned to remove burr adhered after threads are opened.
    Afterwards, the tread surface will be phosphated to improve surface conditions.
