Extension Drill Rod FEATURES:
• Strictly controlled manufacturing processes
• Substantial increase in tensile and torsional strengths
• Improved fatigue resistance
• Customisable configurations
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.
