Heat treatment for the weldzone
Drill pipes are manufacturedas part of an integratedprocess
accomplished in fullyequipped state-of-the-artfacilities at
TenarisNKKTubes.
Drill pipes and tool joints are assembled by frictionwelding.
After removal ofweld bead, each heat affectedzone is quench and
temperedin a unique system to recovermechanical properties.Welded
areas are inspected byUT and MPI.
Quality and Manufacturing
Investment in quality andtechnology is a permanentcommitment
atTenarisNKKTubes, which holds ISO 9001, ISO14001, API Spec. 7 and
API5D certifications.
All employees are fullyinstructed in the importanceof quality
and rigorousquality management systemsare applied in our
operations.
All products are manufacturedin accordance with
customersspecifications and the mostdemanding

FEATURESInterchangeability with APItool joint.
High torque resistance.
Same running speed as API tool joint.
Longer durability & lowerrepair ratio than API
tooljoint.
Bigger ID and/or smaller ODwhich translates intoimproved
hydraulics and/orfish ability.
Suitable for sour drilling(due to minimal hoop stressin box and
lower tensilestress in pin).

HIGH TORQUE RESISTANCENK DSTJTM has excellenttorsional
strengthcompared to API tool joint. NK DSTJTM is suitable fordeep
well drilling, extended reach well or horizontal well drilling.
Variousapplications, smaller OD and larger ID are available.
Make-up TestDiagram on the right showstorque resistance
testssupporting the performanceoffered by NK DSTJTM tooljoint. The
results reflect ahigher performance of theNK DSTJTM NC50 over the
API NC50. This figure shows
the make-up torque curve of both tool joints (6 5/8 x 2 3/4).
Difference, as seen,is remarkable. In the case NK DSTJTM NC50 would
beattached to API S135 5 x19.5 ft-lbs drill pipe, pipebody would
yield before the tool joint does.

FEM AnalysisIn the case of API NC50, very high VME stress
andcompression stress are foundnear external shoulder area and it
is supposed that shoulder deformation will start soon.
NK DSTJTM NC50 clearlyindicates improvedperformance in
comparisonto standard API tool joint.

Hardfacing
TenarisNKKTubes can supply varieties of hardfacing
usingaccumulated technology and experience and also provides
commercially available hardfacing such as ARNCO series,ARMACOR,
etc.
Tool joint break-in
Upon customers request, TenarisNKKTubes will conduct the
break-in of tool joints to eliminate the rig handling timeand
ensure that the process is carried out in a
controlledenvironment.
Accessories
TenarisNKKTubes can supply drill pipe accessories such asdrill
collars, heavy weight drill pipes, and others from
qualifiedsub-suppliers.
SERIES 1000Fine particle hardfacing
SERIES 3000Coarse particle hardfacingwith standard density
SERIES 4000Coarse particle hardfacingwith high density
SERIES 6000 & 8000Hardfacing extends 3 3/4" over the wear
area of thetool joint with fingerprotection on the taperedelevator
shoulder. The superior wear resistanceand minimal casing
wearproperties of SERIES 6000are due to its uniqueapplication
method. SERIES8000s fine surface canminimize casing wear.
After completing therequired make and breakcycles, the tool
joints shallbe separated and cleanedthoroughly.
Connections shall be visuallyinspected for threaddamages.

Proprietary Hardfacing
Apply an even coat of 50%zinc-base thread compoundon pin and
box.
After making up hand tight,the assembled componentswill be made
up at thespecified torque and thenbroken out.

If required, TenarisNKKTubes will provide a certificate for
break-in of tool joints.
