    N80 API Threading Drill Rod 4 1/2 Inch Drill Pipe For Water Well Drilling

    N80 API Threading Drill Rod 4 1/2 Inch Drill Pipe For Water Well Drilling

    Introduction


    Drill pipe is a portion of the overall drill string. The drill string consists of both drill pipe and the bottom hole assembly (BHA), which is the tubular portion closest to the bit. The BHA will be made of thicker walled heavy weight drill pipe (HWDP) and drill collars, which have a larger outside diameter and provide weight to the drill bit and stiffness to the drilling assembly. Other BHA components can include a mud motor, measurement while drilling (MWD) apparatus, stabilizers, and various specialty downhole tools. The drill stem includes the entire drill string, plus the kelly that imparts rotation and torque to the drill pipe at the top.


    FEATURES + OPTIONS:
    In addition to the standard manufacturing processes where customer required, Roschen is able to perform hardbanding, internal coating, thread cold roll and make & break to the highest quality standard.


    TOOL JOINT MAKE & BREAK:
    Factory make & break performed in controlled procedure ensure product consistency. This help to save valuable rig time and cost while reducing risk of mishandling incident and rig downtime.


    SURFACE PROTECTION:
    Phosphate coating are applied to all threads and seal shoulders of connections to improve anti galling and corrosion.

    Roschen can supply internal plastic coating according to customer requirements. The coating forms a protective layer in the pipe ID to prevent corrosion and thus extend the life span of the pipe in the drilling environment.

    ENHANCED FATIGUE RESISTANCE:
    Cold rolling of thread roots has demonstrated the beneficial effects to improve fatigue resistance of the connections by minimizing crack initiation.

    HIGH PERFORMANCE ROTARY SHOULDER CONNECTION:
    Roschen offers its RS-DS and RS-MT series double shoulder connections which outperform conventional API connections to meet the needs of deep, extended and challenging wells with greater torsional capacities.

    INCREASE DRILL PIPE LIFE:
    Hardbanding on the tool joint or wear pad extends the service life of drill pipe. It can be applied in several configurations to suit clients’ requirements. Hardbanding is applied under closely controlled conditions resulting in a uniform, low porosity, wear resistant surface.

    Roschen is authorised to apply market proven hardbanding products including ARNCO 100XT / 300XT, Tuboscope TCS8000 / TCSTI, Duraband NC, Tuffband NC and Castolin OTW 12.

    Extra length tool joints can be incorporated into Roschen drill pipe to increase tong space to provide several recut to the connections.

    Roschen has selected specially engineered metallurgy for its tool joints and tubes. Tool Joints are manufactured from AISI 4137H steel with increased hardenability giving a very uniform microstructure and excellent mechanical properties through the cross section of the tool joint.

    All Roschen Tubes are supplied by Tianjin Pipe Corporation (TPCO) which is a leadingglobal producer of seamless tubes with modern state-of-the-art facilities. TPCO produces the Green Tubes according to Roschen’s chemistry and the tubes are then Austenitized, Quenched and Tempered in Roschen’s own Heat Treatment plant. All mechanical testing is carried out in our own laboratory on site.
