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.

API Drill Pipe 2 3/8" to 6 5/8" OD Fatigue Resistance Drill Rods High Performance 1


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.



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.
