ROSCHEN DRILL PIPE
Roschen manufactures the complete range of API drill pipe products from 2 3/8” OD to 6 5/8” OD in Range 2 and Range 3 sizes up to 48 feet in length. In addition to standard API 5DP specifications, DP-Master also manufactures drill pipe in accordance with the following industry specifications:
1. NS-1
2. NOSRSOK
3. TH HILL
4. IRP 1.8 Sour Service
5. Customer Specific Specifications
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.
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.
