    Wireline Heat Treatment HWT / Q Series Geological Core Drilling Rod And Casing Tubes ​



    Description:

    Our wireline drill rods are all manufactured by CNC machines under DCDMA standard. They're made of

    high quality alloy steel with heat-treated. We also can produce various sizes of casing tubes.
    Drill pipes will be manufactured from seamless steel tube by cold drawn.
    The material is XJY850 / 30CrMnSiA which is one of the best material for geological drilling in China.

    Coring rods are crafted from quality heat treated materials ensuring superior wear resistance, strength,

    and toughness in the most demanding applications.

    Rods and casing are manufactured under stringent industry standards, and are field tested under a variety

    of conditions.

    All rods are designed to be compatible with other rods manufactured to DCDMA standards.




    Specifications:

    1. high quality alloy tube
    2. thru-wall heat treated tube body
    3. consistent concentricity, straightness
    4. tapered threads




    Raw materials:
    SINOCOREDRILL only 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.

    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.

    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.


    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.
