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.
