OCTL Heavy Weight Drill Pipe consists
of two extra long tool joints and one central heavy
wall tube. The tool joints are friction welded to the
central heavy wall tube. The tool joints are manufactured
from AISI 4145 H modified material, fully heat treated
to 285 _ 341 Brinell hardness and 40 ft-lbs. minimum
Charpy V-notch Impact strength. All other physical properties
conform to API Specification 7. The central heavy wall
tube is manufactured from AISI 1340 steel or equivalent.

OCTL
Heavy Weight Drill Pipe is manufactured in compliance
with API Specification 7 and API RP 7G.
Bore Back
on Box ends and API Stress Relief Groove on
Pin ends are standard for all sizes.
Thread roots
are cold worked on all sizes for durability.
All connections
are phosphatized to help prevent galling during
make-up, coated with lubricant and provided
with pressed steel thread protectors or cast
steel thread protectors with lifting bails.
To optimize
wear resistance, hardbanding is standard on
tool joint connections and central upset.
Standard hardbanding
includes one 4" wear pad on both pin and
box end, plus one 1" pad on taper section
of box to prevent fluid cutting and two 3"
wear pads on central upset to prevent wear on
the pipe section. The hardbanding is completely
flush on both tool joints and 1/8" oversize
on the central upset (fully flush on request).
Hardbanding materials include crushed sintered
tungsten carbide of 14-24 mesh, Arnco 100 XT™
or Arnco 200XT™, Armacor-M™, TCS
8000™ or TCS Titanium™
Internal Plastic
Coating, if required (optional).

| Quality
Control: |
A
rigorous quality assurance program is maintained
at every manufacturing step. Each Heavy Weight
Drill Pipe joint is fully inspected by an ultrasonic
unit full length. The Mechanical Properties,
dimensions, and thread inspections are recorded
on the Inspection Certificate. Every connection
is 100% dimensionally inspected and recorded.
|
| |
| Spiral
Heavy Weight Drill Pipe: |
Spiral
Heavy Weight Drill Pipe consists of three spiral
upsets equally spaced between the tool joints.
Spiral Heavy Weight Drill Pipe features more
weight per foot and better hole cleaning characteristics
than standard Heavy Weight Drill Pipe, providing
optimum performance in severe drilling conditions.
