    DESIGN

    Roschen drill pipes are designed with long and smooth transition from upset to tube body to reduce the stress concentrations due to the transition from the upset ID to the drill pipe ID.




    All drill pipe and tool joints are manufactured in our modern and technologically advanced manufacturing facility at Roschen. Each tool joint is forged, machined, processed, inspected and tested by qualified operators to ensure the quality meets or exceed API specifications and customer’s requirements.

    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.
