WT™ Drill Pipe Features
WT™ Drill Pipe Performance Data
Exceptional Torque Strength Combined with a Slimmer OD-ID Envelope – Excellent for Top Drives
Hydraulic efficiency is improved by
maintaining a large ID through the tool
joint. Restrictive IDs are eliminated
because torque strength is not limited
by the thickness under the last
engaged thread of the pin.
PIN
Exceptional torque strength for
drilling in highly deviated holes is
developed through the simultaneous
engagement of opposing flanks of the
WT. The thread flanks provide the
positive torque stop.
A wear indicator is provided by the
separation at the box face. After
extended use, wear in the connection
will permit additional travel of the pin
into the box. A thread wear indicator is
a protrusion on the pin face which is
designed to amply deform showing
adequate signs of a nearly worn out
connection. The bevel provides an
indication of OD wear. The tool joint
retains full rated tension and torque
strength down to the bevel diameter.
Stress created by torque is distributed throughout the length of the
thread. The thread stab flank provides
the reaction surface to the equal and
opposite force generated on the
thread load flank when torque is
applied. The reaction surface on
conventional tool joints, the torque
shoulder, is eliminated. This prevents
the concentration of stress at the last
pin thread inherent in conventional
tool joints.
Excellent for highly deviated,
extended reach, and horizontal applications where high bending loads
exist. Pre-loading both stab and load
flanks at make-up allows the WT to
cycle between the tension and compression associated with bending with
minimal pin to box movement.
Stress reduction grooves, machined
in the root of the large step of the pin,
provide a path for excess thread compound to escape. This helps to reduce
high stress levels associated with
over-doping.
The tapered, two-step thread
profile stabs deep and makes up
easily. Trouble free make-up is developed with the rugged, coarse pitch
thread and steep taper. The WT tool
joint exhibits the same field proven
stabbing and make-up characteristics
of the old Hydril Type “IF”, Type “SH”,
and Type “F” drill pipe tool joints.
Plastic coating can be applied
to the end of pin and box shoulder
since the pin end does not contact
the box shoulder. Plastic coating is
protected since this shoulder gap will
not close up before the wear indicator. With the large ID through the tool
joint, wireline damage and coating
discontinuities are reduced.
BOX
Worldwide repair and accessory
threading facilities are available to
ensure peak performance and maximum life.

Torque strength is independent of
the tool joint OD. With the torque
strength developed by the flanks of
the WT, drilling wear on the OD or ID
of the tool joint will not reduce torque
strength. The torque strength rating of
the drill string is retained for the life of
the tool joint.
Pipe body sealing capability for
both internal and external pressure is
provided by the WT and lubricant.
Damaged threads can be field
repaired, significantly reducing shop
repair frequency. There is no torque
shoulder seal that can unload during
high tension load applications. The
WT retains sealing performance under
high axial loads.

WT™ Drill Pipe Features
WT™ Drill Pipe Performance Data
Exceptional Torque Strength Combined with a Slimmer OD-ID Envelope – Excellent for Top Drives
Hydraulic efficiency is improved by
maintaining a large ID through the tool
joint. Restrictive IDs are eliminated
because torque strength is not limited
by the thickness under the last
engaged thread of the pin.
PIN
Exceptional torque strength for
drilling in highly deviated holes is
developed through the simultaneous
engagement of opposing flanks of the
WT. The thread flanks provide the
positive torque stop.
A wear indicator is provided by the
separation at the box face. After
extended use, wear in the connection
will permit additional travel of the pin
into the box. A thread wear indicator is
a protrusion on the pin face which is
designed to amply deform showing
adequate signs of a nearly worn out
connection. The bevel provides an
indication of OD wear. The tool joint
retains full rated tension and torque
strength down to the bevel diameter.
Stress created by torque is distributed throughout the length of the
thread. The thread stab flank provides
the reaction surface to the equal and
opposite force generated on the
thread load flank when torque is
applied. The reaction surface on
conventional tool joints, the torque
shoulder, is eliminated. This prevents
the concentration of stress at the last
pin thread inherent in conventional
tool joints.
Excellent for highly deviated,
extended reach, and horizontal applications where high bending loads
exist. Pre-loading both stab and load
flanks at make-up allows the WT to
cycle between the tension and compression associated with bending with
minimal pin to box movement.
Stress reduction grooves, machined
in the root of the large step of the pin,
provide a path for excess thread compound to escape. This helps to reduce
high stress levels associated with
over-doping.
The tapered, two-step thread
profile stabs deep and makes up
easily. Trouble free make-up is developed with the rugged, coarse pitch
thread and steep taper. The WT tool
joint exhibits the same field proven
stabbing and make-up characteristics
of the old Hydril Type “IF”, Type “SH”,
and Type “F” drill pipe tool joints.
Plastic coating can be applied
to the end of pin and box shoulder
since the pin end does not contact
the box shoulder. Plastic coating is
protected since this shoulder gap will
not close up before the wear indicator. With the large ID through the tool
joint, wireline damage and coating
discontinuities are reduced.
BOX
Worldwide repair and accessory
threading facilities are available to
ensure peak performance and maximum life.

Torque strength is independent of
the tool joint OD. With the torque
strength developed by the flanks of
the WT, drilling wear on the OD or ID
of the tool joint will not reduce torque
strength. The torque strength rating of
the drill string is retained for the life of
the tool joint.
Pipe body sealing capability for
both internal and external pressure is
provided by the WT and lubricant.
Damaged threads can be field
repaired, significantly reducing shop
repair frequency. There is no torque
shoulder seal that can unload during
high tension load applications. The
WT retains sealing performance under
high axial loads.

WT™ Drill Pipe Features
WT™ Drill Pipe Performance Data
Exceptional Torque Strength Combined with a Slimmer OD-ID Envelope – Excellent for Top Drives
Hydraulic efficiency is improved by
maintaining a large ID through the tool
joint. Restrictive IDs are eliminated
because torque strength is not limited
by the thickness under the last
engaged thread of the pin.
PIN
Exceptional torque strength for
drilling in highly deviated holes is
developed through the simultaneous
engagement of opposing flanks of the
WT. The thread flanks provide the
positive torque stop.
A wear indicator is provided by the
separation at the box face. After
extended use, wear in the connection
will permit additional travel of the pin
into the box. A thread wear indicator is
a protrusion on the pin face which is
designed to amply deform showing
adequate signs of a nearly worn out
connection. The bevel provides an
indication of OD wear. The tool joint
retains full rated tension and torque
strength down to the bevel diameter.
Stress created by torque is distributed throughout the length of the
thread. The thread stab flank provides
the reaction surface to the equal and
opposite force generated on the
thread load flank when torque is
applied. The reaction surface on
conventional tool joints, the torque
shoulder, is eliminated. This prevents
the concentration of stress at the last
pin thread inherent in conventional
tool joints.
Excellent for highly deviated,
extended reach, and horizontal applications where high bending loads
exist. Pre-loading both stab and load
flanks at make-up allows the WT to
cycle between the tension and compression associated with bending with
minimal pin to box movement.
Stress reduction grooves, machined
in the root of the large step of the pin,
provide a path for excess thread compound to escape. This helps to reduce
high stress levels associated with
over-doping.
The tapered, two-step thread
profile stabs deep and makes up
easily. Trouble free make-up is developed with the rugged, coarse pitch
thread and steep taper. The WT tool
joint exhibits the same field proven
stabbing and make-up characteristics
of the old Hydril Type “IF”, Type “SH”,
and Type “F” drill pipe tool joints.
Plastic coating can be applied
to the end of pin and box shoulder
since the pin end does not contact
the box shoulder. Plastic coating is
protected since this shoulder gap will
not close up before the wear indicator. With the large ID through the tool
joint, wireline damage and coating
discontinuities are reduced.
BOX
Worldwide repair and accessory
threading facilities are available to
ensure peak performance and maximum life.

Torque strength is independent of
the tool joint OD. With the torque
strength developed by the flanks of
the WT, drilling wear on the OD or ID
of the tool joint will not reduce torque
strength. The torque strength rating of
the drill string is retained for the life of
the tool joint.
Pipe body sealing capability for
both internal and external pressure is
provided by the WT and lubricant.
Damaged threads can be field
repaired, significantly reducing shop
repair frequency. There is no torque
shoulder seal that can unload during
high tension load applications. The
WT retains sealing performance under
high axial loads.

WT™ Drill Pipe Features
WT™ Drill Pipe Performance Data
Exceptional Torque Strength Combined with a Slimmer OD-ID Envelope – Excellent for Top Drives
Hydraulic efficiency is improved by
maintaining a large ID through the tool
joint. Restrictive IDs are eliminated
because torque strength is not limited
by the thickness under the last
engaged thread of the pin.
PIN
Exceptional torque strength for
drilling in highly deviated holes is
developed through the simultaneous
engagement of opposing flanks of the
WT. The thread flanks provide the
positive torque stop.
A wear indicator is provided by the
separation at the box face. After
extended use, wear in the connection
will permit additional travel of the pin
into the box. A thread wear indicator is
a protrusion on the pin face which is
designed to amply deform showing
adequate signs of a nearly worn out
connection. The bevel provides an
indication of OD wear. The tool joint
retains full rated tension and torque
strength down to the bevel diameter.
Stress created by torque is distributed throughout the length of the
thread. The thread stab flank provides
the reaction surface to the equal and
opposite force generated on the
thread load flank when torque is
applied. The reaction surface on
conventional tool joints, the torque
shoulder, is eliminated. This prevents
the concentration of stress at the last
pin thread inherent in conventional
tool joints.
Excellent for highly deviated,
extended reach, and horizontal applications where high bending loads
exist. Pre-loading both stab and load
flanks at make-up allows the WT to
cycle between the tension and compression associated with bending with
minimal pin to box movement.
Stress reduction grooves, machined
in the root of the large step of the pin,
provide a path for excess thread compound to escape. This helps to reduce
high stress levels associated with
over-doping.
The tapered, two-step thread
profile stabs deep and makes up
easily. Trouble free make-up is developed with the rugged, coarse pitch
thread and steep taper. The WT tool
joint exhibits the same field proven
stabbing and make-up characteristics
of the old Hydril Type “IF”, Type “SH”,
and Type “F” drill pipe tool joints.
Plastic coating can be applied
to the end of pin and box shoulder
since the pin end does not contact
the box shoulder. Plastic coating is
protected since this shoulder gap will
not close up before the wear indicator. With the large ID through the tool
joint, wireline damage and coating
discontinuities are reduced.
BOX
Worldwide repair and accessory
threading facilities are available to
ensure peak performance and maximum life.

Torque strength is independent of
the tool joint OD. With the torque
strength developed by the flanks of
the WT, drilling wear on the OD or ID
of the tool joint will not reduce torque
strength. The torque strength rating of
the drill string is retained for the life of
the tool joint.
Pipe body sealing capability for
both internal and external pressure is
provided by the WT and lubricant.
Damaged threads can be field
repaired, significantly reducing shop
repair frequency. There is no torque
shoulder seal that can unload during
high tension load applications. The
WT retains sealing performance under
high axial loads.
