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.
