DRILL PIPE
Drill Pipe
Proper break-in is probably the most important factor affecting the life of
the tool joint connection. Here are some recommendations to follow:
1. Proper make-up torque is determined by the connection type, size,
OD and ID and may be found in torque tables. If a torque range is
given, maximum recommended makeup torque should be applied
when possible.
2. Make up connections slowly, preferably using chain tongs. High
speed kelly spinners or the spinning chain used on initial make-up
can cause galling of the threads.
3. Tong them up to the predetermined torque using a recently
calibrated torque gauge to measure the required line-pull.
Note: Monitor breakout torque. It should be less than or no greater
than make-up torque. If it is greater, the connection should be
cleaned, inspected and repaired, before it is made up again.
4. Breakout, visually inspect, redope and make up two more times
before running in hole. Always use backup tongs to make and
break connections.
5. Stagger breaks on each trip so that each connection can be checked,
redoped and made up every second or third trip, depending on the
length of drill pipe and size of rig.
A new string of drill pipe deserves good surface handling equipment and
tools. Check slips and master bushings before damage occurs to the tube.
(See the IADC Drilling Manual for correct measurements).
Do not stop the downward movement of the drill stem with the slips. This
can cause crushing or necking down of the drill pipe tube. The drill pipe can
also be damaged by allowing the slips to ride the pipe on trips out of the
hole.
Good rig practices will help eliminate time consuming trips in the future,
looking for washouts or fishing for drill pipe lost in the hole. For more
information refer to the IADC Drilling Manual.

Notes:
1. The use of outside diameters (OD) smaller than those listed in the table may be acceptable on Slim Hole
(S.H.) tool joints due to special service requirements.
2. Make-up torque values may be lower than those published in API RP7G Latest Edition. The make-up
values are lower due to the combined torsional and tensile loads found in service conditions.

Types of Grant Prideco Double-Shouldered
Connections
Double-shouldered connections offered by NOV Grant Prideco include:
• HI TORQUE® (HT™) – First generation double-shouldered connection
providing approximately 40% more torque capacity than API
connections of equivalent dimensions. Not interchangeable with
API connections.
• eXtreme® Torque (XT®) – Second generation double-shouldered
connection providing approximately 65% more torque capacity than
API connections of equivalent dimensions. Not interchangeable with
API connections. Primary differences exist between HT and XT connections are XT has a shallow taper and a fatigue-resistant thread
form.
– eXtreme® Torque with Metal-to-Metal Seal (XT-M™) –
Industry's first gas-tight pressure rated rotary-shouldered
connection with a metal-to-metal seal. The radial seal provides
a pressure rating of 15,000 psi internal, and 10,000 psi external.
This provides torque capacity similar to that of XT connections.
Not interchangeable with API connections.
The figure below illustrates the taper difference between HT® and XT®
connections.
HT
XT
• Grant Prideco Double Shoulder® (GPDS®) – Double-shouldered
connection that is interchangeable with API connections and
provides approximately 40% more torque capacity than API
connections of equivalent dimensions.
12
• TurboTorque® – Third generation double shoulder connection
providing approximately 80% more torque capacity than API
connections of equivalent dimensions, and 10-15% over XT®.
Not interchangeable with API connections. Primary benefits
for TurboTorque connections include: it saves time, cuts costs;
increases torque capacity; optimizes hydraulics; improves
clearance and fishability; reduces risk of failure; and extends life
of the connection itself.
– TurboTorque-M™ with Metal-To-Metal Seal – Gas-tight
pressure-rated rotary shoulder connection. The radial seal
provides a pressure rating of 20,000 psi internal, and
10,000 psi external. Torque capacity is similar to that of
TurboTorque connections. Not interchangeable with API
connections.

TurboTorque connections are the first in the industry to provide
a Turbo-MUT™. Also known as "torque-on-demand", Turbo-MUT
provides an additional 8% of torque capacity for those unusual
drilling situations when additional torque is required. Most of the
testing and design validation for the TurboTorque family were
conducted on connections made up to the Turbo-MUT value.

The following sections provide general guidelines for running and handling doubleshouldered connections. Connection-specific procedures are available directly from
NOV Grant Prideco and can be downloaded from: www.nov.com/grantprideco
Picking Up Pipe with Double-Shouldered
Connections for the First Time
• Visually examine the thread protectors for damage such as dents or
crushing. If any thread protectors are damaged, inspect the threads
on that joint for damage.
• If the joints were shipped to the rig with rust preventive on the
threads, it must be removed. Use soap and water, steam or a
degreasing solvent such as Varsol. No residue should remain on the
threads after cleaning.
• If the joints were shipped to the rig with thread compound, it is
not necessary to remove the thread compound unless a problem
is suspected.
• Inspect the threads for damage or for foreign material.
• Before the joints are put in service, the threads, the primary make-up
shoulders and secondary make-up shoulders must be coated with a
good quality rotary-shouldered connection thread compound.
Tool Joint Break-in
Most drill pipe connections are broken in during manufacture. The
following break-in procedure is recommended for connections which
have not been broken in during manufacture.
Step 1: Make up the joints to the maximum recommended make-up
torque, and then break them out. If the break-out torque is
less than the make-up torque, the joints do not have to be
separated.
Step 2: Make up the joints again to the same make-up torque and
break them out. Separate the pin and box and reapply thread
compound.
Step 3: Make up the joints again to the same make-up torque and they
are ready for service.
Note: The break-out torque should be less than the make-up
torque. If the break-out torque is more than the make-up torque,
separate the joints and inspect them for damage.

Special Considerations When Running XT®,
TurboTorque®, XT-M™ and TurboTorque-M™
Connections
• Check to ensure the counterbalance on the top drive is working
properly and provides a minimum amount of weight applied to the
connection during stabbing and make-up.
• Ensure the bore through the top drive bell stabbing guide (top drive
flipper) is no more than ½” larger in diameter than the box tool joint
diameter.
• Because of the shallow taper, connections do not stab as deep into
the box as API connections. Alignment of the pin to the box when
stabbing and spinning up is more critical for shallow taper connections.
• Proper alignment, along with slow initial make-up of the starting
threads is necessary with XT and XT-M connections. Use chain tongs
or slow speed spinners when spinning in the starting threads. Highspeed spinners may be used after the starting threads are engaged.
• Minor thread damage may occur within the starting threads. This is
not detrimental to the connection and protruding metal should be
removed with a soft grinding wheel or a file.
• A stabbing guide is required when running XT, XT-M and
TurboTorque-M™ connections and alignment should be verified
before spinning up. A stabbing guide is recommended for HT®,
GPDS®, and TurboTorque connections.
21
TAB 2 RSHandbook_DSC.indd Sec1:21
11/18/2010 5:37:09 PM
Application of Thread Compound to
Double-Shouldered Connections
• All contacting surfaces – the threads, the primary shoulders, secondary shoulders and 15° metal seal (XT-M™, TurboTorque-M™) – must
be coated with a good quality rotary-shouldered connection thread
compound. Copper-based thread compounds are recommended
because of the anti-galling resistance, the repeatability of frictional
characteristics and the generally higher friction coefficient (yielding
less stress in the connection for equivalent MUTs). Standard API
thread compounds are sufficient.
• Some drilling fluids or drilling fluid additives may affect the frictional
properties of the tool joint and thread compound. If this is the case,
rinse the drilling fluid off the connections before applying thread
compound.
• Remove drilling fluid from the secondary shoulder and 15° metal seal
(XT-M, TurboTorque-M) of the box before making up the connection
for the trip in the hole. Trapped drilling fluid can promote corrosion
of the secondary shoulders.
• Racking the pipe will wipe thread compound off the secondary
shoulder and pin nose. If pins are doped coming out of the hole,
reapply compound to the secondary shoulder before the connections
are made-up.
NOTE: For XT-M and TurboTorque-M connections, localized corrosion
or pitting may occur on the 15° metal seal if racked back without
thread compound applied to it. This is more common with completion fluids than common drilling fluids. Apply a liberal and even
coat of quality thread compound to the 15° seal when racking back
XT-M and TurboTorque-M connections.

Tong Height
• Bucking up tool joints with tongs can put high bending loads in
the pipe.
• Review the IADC Drilling Manual Latest Edition or Tong Height Figure
in API RP7G Latest Editon about height of tool joint above slips to
prevent bending pipe during tonging.

Alignment when Making up Connections
• Galling and other damage can occur during stabbing and spinning
connections up.
• A stand of pipe can weigh between 1,500 lbs and 2,300 lbs. At initial
contact, the weight could be supported by the sharp edge of one
thread against the flank of the mating thread (see figure below). This
can cause high contact stresses and may wipe the thread compound
off.
• Slight misalignment of the pin and box can cause further increases in
the stresses when spinning up.
• The “whipping” action of spinning pipe can cause high loads on
threads.
NOTE: Alignment of the pin to the box when stabbing and spinning
up is more critical for XT® and XT-M™ connections. A stabbing guide
is required when running XT and XT-M. Alignment for all connections should be verified before spinning up.

Contact of sharp edge of
pin thread on box flank
Tripping
• Alternate breaks when tripping so that each joint will be broken-out
every third trip.
• Monitor break-out torque.
• The break-out torque should be less than the make-up torque. High
break-out torque is an indication of down-hole make-up or thread
damage.
• Do not let the end of the pin strike the box make-up shoulder when
stabbing the pin in the box. Stabbing guides are required for XT and
XT-M connections, and recommended for all other Grant Prideco

Standing Pipe Back
• Using normal drill pipe care and handling practices, no special care
is required to protect the pin nose when standing the pipe back. The
pin nose is not a seal. Minor damage to the pin nose from standing
the pipe back does not affect the connection’s performance. Remove
protruding metal with a soft grinding wheel or standard file.
• It is not necessary to use thread protectors when standing the pipe
back.
• Do not use pressed steel thread protectors when standing pipe back.
They could allow the weight of the stand to be supported by the
primary make-up shoulder of the connection on the sharp edge of
the thread protectors.
• Apply a liberal and even coat of quality thread compound to the
15° metal seal when racking back XT-M™ and TurboTorque-M™
connections.
Sharp edge of thread
protector can damage
shoulder.

Downhole Make-up
• Downhole make-up can be detected by high break-out torque. The
break-out torque should be less than the make-up torque.
• If downhole make-up is suspected, punch mark the pin and box next
to the make-up shoulders when tripping into the hole (after the connection is made up).
• If downhole make-up occurs, the position of the punch marks will
change.
• Downhole make-up can cause
– Compressed box counterbores
– Compressed pin noses
Milled hardness flat
Punch marks
Apply punch marks in line
with hardness flat to make
them easier to find.

The following sections provide information and general guidelines regarding the field
inspection of Grant Prideco double shoulder connections and are not intended to
replace NOV Grant Prideco Field Inspection Procedures and Drawings.
Connection type-specific Field Inspection Procedures and connection type and sizespecific Field Inspection Drawings are available direct from NOV Grant Prideco and can
be downloaded from: www.nov.com/grantprideco.com
Make-up Shoulder and Bevel Diameter
• The primary make-up shoulders provide the seal for the connection
(HT®, XT®, GPDS®, TurboTorque®). For XT-M™ and TurboTorque-M™,
the primary seal is the 15° metal seal and the backup seal is the
primary make-up shoulder.
• The primary make-up shoulders and 15° metal seal (XT-M,
TurboTorque-M) should be inspected frequently using current NOV
Grant Prideco Field Inspection Procedures for the applicable
connection type.
• Proper operation and correct shoulder loads depend on the pin
length and box depth of double shoulder connections being within
specifications. The pin length and box depth are shown on the Field
Inspection Drawing for the particular size and type connection.
• No more than 1/32” should be removed from either the primary or
secondary make-up shoulder at any one refacing. No more than 1/16”
cumulatively should be removed from either the primary or
secondary make-up shoulder. The correct pin length and box depth
must be maintained when resurfacing make-up shoulders.
• The NOV Grant Prideco benchmark and Xmark™ benchmark are
references for checking how much material has been removed from
make-up shoulders.
• The surface finish of the primary make-up shoulder should be 150
RMS or better.
• When NOV Grant Prideco double shoulder connections are refaced,
the bevel does not need to be remachined.
• The pin nose is not a seal, it is a mechanical stop. The pin nose must
be free of raised metal or other imperfections that could prevent
proper make up or cause galling. Pin nose damage can be repaired
with a hand file.
• Refacing is not allowed for metal seals and must be redressed by an
NOV GRP licensed machine shop.

Checking Pin Length
• The pin length can be checked with a dial indicator or depth
micrometer. If the pin length is short by 1/32 inch or less, the pin
can be repaired by resurfacing the primary shoulder.
• If the pin length is short by more than 1/32 inch, the pin must be
recut.
• If the pin length is too long by 1/32 inch or less, the pin can be
repaired by resurfacing the pin nose.
• If the pin length is too long by more than 1/32 inch, the pin must
be recut.
If the pin nose does not contact the gauge when used as shown in the
figure, the length should be inspected with measuring instruments that
determine the actual distance between the shoulders.
30
TAB 2 RSHandbook_DSC.indd Sec1:30
11/18/2010 5:37:11 PM
Checking Box Depth
• The box depth can be checked with a dial indicator or depth micrometer. If the box depth is short by 1/32 inch or less, the box can be
repaired by resurfacing the secondary shoulder.
• If the box depth is short by more than 1/32 inch, the box must be
recut.
• If the box depth is too long by 1/32 inch or less, the box can be
repaired by resurfacing the primary shoulder.
• If the box depth is too long by more than 1/32 inch, the box must be
recut.
If the primary shoulder does not contact the gauge when used as
shown in the figure, the depth should be inspected with measuring
instruments that determine the actual distance between the shoulders.

11/18/2010 5:37:11 PM
Special Considerations When Inspecting XT®,
TurboTorque®, XT-M™ and TurboTorque-M™
Connections
• For XT and XT-M, the stab flank to crest radius of the starting four to
five threads of the pin and box connections round off during break-in
and normal operation. Minor thread damage may occur within these
starting threads. This is not detrimental to the connection and protruding metal should be removed with a soft grinding wheel or a file.
• The XT-M and TurboTorque-M connections contain a 15° metal seal
near the pin and box secondary shoulders. This is the primary sealing
surface for the connection.
– Round pit type defects up to 1/32” in diameter and not
exceeding 1/32” in depth are permissible.
– Multiple pits of this type are acceptable provided there is at
least a 1” separation between pits, along the circumference of
the seal.
– Circumferential lines or marks are acceptable provided they
cannot be detected by rubbing a fingernail across the surface.
– Areas highlighted in the figure below are the non-contacting
areas of the seal. Damage or pitting is permitted in these areas
of the seal provided the balance of the contact surface is
without damage exceeding the requirements above.
– XT-M and TT-M connections may not be refaced. Damages
exceeding requirements for the threads, seal and/or shoulder
faces require the connection to be redressed by Grant Prideco
licensed machine shops.

Heavy Weight Drill Pipe
Heavy Weight drill pipe (HWDP) was developed to provide a gradual
transition from heavy drill collars to relatively lightweight drill pipe. By
providing a gradual change in weight and rigidity, HWDP reduces
connection fatigue problems and increases drill stem service life. And,
because it bends more easily than drill collars, it simplifies directional
control in high-angle and horizontal drilling. HWDP has less wall contact
than drill collars, reducing differential sticking tendencies. Spiraled HWDP
configurations further decrease differential sticking tendency while
helping to remove cuttings out of the annulus. NOV Grant Prideco offers
three types of HWDP configurations to meet the challenge of severe
drilling conditions.

Drill Collars
Care And Maintenance
Initial Make Up
Even though quality connections are heavily coated with phosphate, thread
damage is not always prevented. A generous and thorough application of
high-quality thread dope (40 to 60 percent metallic zinc minimum) will
help prevent galling.
New connections should be “walked in” with chain tongs. Always use the
recommended make-up torque for the thread design. Exercise care to
maintain calibrated torque measuring and indicating gauges for future use.
After initial make-up, break-out the connection, visually inspect, redope
and make-up two more times before running in the hole.
Note: Monitor break-out torque – it should be less than or no
greater than make-up torque. If it is greater, the connection
should be cleaned, inspected and repaired before it is made up
again.
Maintenance
Use thread protectors on both connections when handling drill collars.
Alternate different joints on each trip. Clean and inspect the individual
connections.
DRILL
COLLARS
Qualified personnel should periodically conduct a magnetic particle/black
light inspection. Collars that are left idle or put in storage should be
cleaned, inspected, repaired and rust-proofed as necessary before installing thread protectors.
Hardbanding Repair and Re-Application
Extreme caution should be used when welding drill collar material in the
field. This material is high alloy steel; carefully heat-treated to provide
optimum performance. When repair welding or hardbanding, use proper
preheat, interpass and post-heat temperatures to prevent cracking and
metallurgical degradation of the collar.
Your NOV Grant Prideco licensed repair facility can provide welding repair
service to factory specifications to ensure weld area integrity. Contact your
representative today, or visit www.GrantPrideco.com for more information.

Care and Maintenance
Bending Strength Ratios
Sizes less than six inches should have a Bending Strength Ratio (BSR) of
2.25:1 to 2.75:1. For conditions that require high RPM and small collars
compared to the hole size, use 2.25:1 to 3.00:1. If the RPM is kept low
and the collars are closer to the hole size, use 2.25:1 to 3.20:1. In corrosive
environments, use 2.50:1 to 3.00:1.
The current industry BSR calculation for single-shoulder rotary-shouldered
connections are not applicable for double-shouldered connections (HT®,
XT®, GPDS®) as appropriate target ranges are yet to be defined due to limited industry experience and testing of available types/sizes.

Notes: Torque figures preceded by an asterisk indicate that the weaker member for the corresponding outside diameter (OD) and bore is the BOX. For all other torque values the weaker member is the PIN.
Normal torque range is tabulated value plus 10%. Higher torque values may be used under extreme
conditions.

Notes: 1. Basis of calculations for recommended make-up torque assumed the use of a thread compound
containing a 0.08 coefficient of friction, applied thoroughly to all threads and shoulders, and
using the modified Jack Screw formula in Appendix A, paragraph A.8 and a unit stress of 62,500
psi in the box or pin, whichever is weaker.
2. In each connection size and type group, torque values apply to all connection types in the group,
when used with the same drill collar outside diameter and bore, i.e. 2 3/8, API IF, API NC 26, and 2
7/8 Slim Hole connections used with 3 1/2 x 1 1/4 drill collars all have the same minimum make-up
torque of 4,600 ft-lb, and the BOX is the weaker member.
3. Make-up torque for 2 7/8 PAC connection is based on 87,500 psi stress and other factors listed in
note 1.
4. Make-up torque for H-90 connection is based on 56,200 psi stress and other factors listed in note 1.

Notes:
1. The minimum size drill collar, calculated from the Lubinski and Hock equation, with the specific sizes of
hole and casing combination, is too large for conventional fishing tools. When the minimum drill collar
diameter is too large to washover and/or catch with an overshot, other steps should be taken. Some of
the possibilities are as follows:
• Use turned down casing couplings.
• Use integral joints on casing.
• Under-ream the hole.
• Run smaller size casing.
2. Use a packed hole assembly instead of a pendulum.
3. Not API standard size drill collar.

General Notes on Subs
1. Other lengths may be specified by the customer, example 48 inches.
2. Fishing neck (tong space) length, unless specified otherwise, is one
half the overall length of the sub. For example, 18 inch fishing neck
(tong space) on a 36 inch sub; 24 inch on a 48 inch sub.
3. Bevel Diameters:
A. If the connection is to screw onto a piece of Drill Pipe (pipe, D/P)
use the bevel diameters listed on drawing HB1003 in the “Bevel
Dia.” section of the Machining Handbook.
B. If the connection is a Bit Box (with or without a float bore) use the
bevel diameters listed in column B in the top chart of drawing
HB1017 “Float Bore” in this section of the Machining Handbook.
C. If the connection is to screw onto a Drill Collar (Collar, D/C) use
the bevel diameters listed at the bottom of the drawing of the
specified connection.
4. Float bore not applicable for double-shouldered connections

Picking Up a New Kelly
Under ideal conditions, a new Drive Bushing assembly should be used
when picking up a new kelly. If this is not possible, the following checklist should be performed:
1. Inspect surfaces on Drive Bushing rollers for wear. Example: For a
5 1/4 inch Hex, if wear exceeds 1/8 inch, reverse the rollers.
2. Check clearance between roller face and side of kelly. Example: For
a 5 1/4 inch Hex, if clearance is more than 1/8 inch, inspect roller
assembly and Kelly Bushing for excessive wear.
3. Inspect bottom taper of Drive Pins for wear and damage. Replace
as necessary.
4. Inspect for clearance between upper and lower halves, replace if
clearance is zero.
Note: A worn out Drive Bushing can severely damage a new kelly.

Well Control
Height of Kick (ft) = Pit Gain ÷ Annular Capacity in Bbls/ft
Density of Kick Fluids (ppg) = MW – [(SICP-SIDPP) ÷ Height of Kick ÷
0.052]
Approximate Typical Fluid Densities: Gas-2ppg, Oil-7ppg, Water-9ppg
Lag Time Rule of Thumb: Pressure changes from choke movement will take
about two seconds per 1000’ of depth to travel down the annulus and up
the drill pipe to the DP gauge.
Sacks of Barite needed to Weight-Up Mud = Bbls Mud x 14.7 x (KWMOWM) ÷ (35.4-KWM)
Volume Increase in Bbls from adding Barite = Sacks Added ÷ 14.9
Volume Increase in Bbls from adding Barite = (Gel) = Sacks Added ÷ 8.75
Triplex Pump Output (bbls/stk @ 100%) = 0.000243 x Stroke Length x
(Liner Dia)2
Duplex Pump Outlet (bbl/stk @ 100%) = 0.000162 x Stroke x
[(2 x Liner Dia2) - Rod Dia2]
Annular Capacity (bbls/ft) = (ID2hole - OD2pipe) ÷ 1029

Formulas Used In Well Control
and Drilling Operations
Calculating Pressure, psi and Pressure Gradients, psi/ft
1. Determine pressure gradient, psi/ft
(Mud Weight, ppg) x (0.052) = psi/ft
2. Determine hydrostatic pressure, psi (H.P.)
(Mud Wt., ppg) x (0.052) x (T.V.D., ft) = psi
3. Maximum allowable shut in casing pressure
Maximum
Allowable Mud Wt., ppg
Mud Wt.
in use
ppg
x (0.052) x (TVD, ft.) = psi

Converting Pressures, psi into mud weight, ppg
Anytime a pressure is to be converted to mud weight use the following formulas
• Mud Weight, ppg (MW)
(Pressure, psi) ÷ (0.052) ÷ (TVD, ft) = Mud Weight, ppg
• Kill Weight Mud, ppg (KWM)
(SIDPP, psi) ÷ (0.052) ÷ (TVD, ft) + (O.M.W.) = Kill Wt., ppg
• Equivalent Mud Weight, ppg (EMW)
(pressure, psi) ÷ (0.052) ÷ (TVD, ft) = EMW, ppg
• Equivalent Circulating Density, ppg (ECD)
Annular
Pressure
Loss, psi
÷ (0.052) ÷ (TVD, ft) + (OMW) = ECD, ppg
• Maximum Allowable Mud Weight, ppg (MAMW)
Leak-Off
Pressure
Loss, psi
÷ (0.052) ÷ (TVD, ft) +
Test
Mud
Weight
= MAMW, ppg
• Converting Pressure Gradient, psi/ft to Mud Wt, ppg
(Pressure Gradient, PSI/ft.) ÷ (0.052) = Mud Wt, ppg
OMW - original mud weight
SIDPP - shut in drill pipe pressure
TVD - true vertical depth
