ROSCHEN HEAVY WEIGHT DRILL PIPE

Roschen manufactures heavy weight drill pipe from 2 7/8” OD to 6 5/8” OD in Range 2 and Range 3 lengths. Heavy Weight Drill Pipe can be supplied either in Conventional Friction Welded or Integral design in accordance with API Spec 7-1 and NS-1 specifications. Heavy Weight Drill Pipe can be supplied in Conventional Slick, Spiralled or Tri-Spiral forms. Apart from standard API and NS-1 grades, Roschen can supply Sour Service Heavy Weight Drill Pipe in friction welded or integral form.

STANDARD HEAVY WEIGHT DRILL PIPE

Roschen standard heavy weight drill pipe assembly is made up of pin and box tool joints and a heavy weight tube with center upset or wear pad.

This configuration helps to prevent stress concentration which could otherwise occur and allows directional drilling with controlled torque and reduce differential pressure sticking.

The service life of the Heavy Weight Drill Pipe is extended to maximize your investment by;

• Providing extra-long tool joint that increases tong space which allows more connection recuts.
• Reducing wear rate on tube OD through additional protection by the center upset or wear pad which keep the tube away from the hole.

HEAVY WEIGHT SPIRAL DRILL PIPE

Roschen heavy weight spiral drill pipe handles maximum stresses induced at tough drilling environments in vertical and directional wells.

The heavy weight spiral drill pipe shares many of the same features from the standard heavy weight drill pipe except that the pipe body has an enlarged center section with three spiral grooves.

The spiral design adds following advantages;

• Better reduction in differential sticking
• Increased weight and stiffness
• Minimizes wear
• Improves cutting circulation for better hole cleaning

ENHANCED FATIGUE RESISTANCE

Cold rolling on the thread roots of every connection is necessary to increase the connection’s ability to resist failure from cyclic stresses on the thread roots when stiffer heavy weight drill pipe undergoes repeated severe tensile and compressive stresses at drilling operation.

Cold rolling hardens the thread roots inducing compressive stress that minimise crack forming to increase fatigue resistance.

API Bore back on the box connection or stress relief groove on the pin connection can further enhanced fatigue resistance on conventional API connections.


HIGH PERFORMANCE ROTARY SHOULDER CONNECTIONS

Roschen offers its DS and 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 suits 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 are incorporated into Roschen heavy weight drill pipe to increase tong space to provide several recut to the connections.
