DRILL PIPE
OCTL offers a complete range of Drill
Pipe with Tool Joints attached from
2 m" OD to 5 a" OD according to
API Specification 5DP and guidelines
presented in API RP7G and Premium
Specifications.
Drill Pipes with 95% Remaining Body Wall and Extra Long Tool
Joints and Extra Long Internal Taper and Special Grades are also
offered upon Customer’s request. ‘Holiday Free’ Internal Plastic
Coating is also offered upon Customer’s request.
OCTL Drill Pipe and Tool Joints are manufactured from the finest
quality steel available. Each step of the manufacturing process is
performed with the highest degree of accuracy to meet or exceed
API Specifications as well as the Industry Standards.
Plain End Pipes and Tool Joint Forgings are procured to specific
metallurgical chemistries and are matched for physical properties,
welding compatibility, weld strength and product integrity.
Plain end pipe is upsetted and heat-treated full length by the
Quench and Temper process to achieve uniform mechanical
properties. The upset profile is designed to blend with the inside
diameter of the pipe body with a generous radius giving a smooth
transition from the thicker cross section of the upset to the pipe
body. The smooth transition minimizes the stress concentrations.
The heat-treated pipe is tested for tensile and impact properties and
are 100% non-destructively inspected for possible longitudinal and
transverse defects, wall thickness and grade verification. Dry
magnetic particle inspection of the upset ends is done to ensure
that the upsets are free from defects. The OD & ID and face of the
upsets are CNC machined for a clean surface as part of pipe
preparation prior to welding.

Tool Joint Forgings are turned, bored and faced prior to heat
treatment by the Quench and Temper process to produce a
uniform microstructure, high ductility, and other mechanical
properties in accordance with API Specifications. The heat
treatment is done under controlled atmosphere for consistent
quality. The hardness of every tool joint is checked by Brinell
Hardness Tester and recorded. The tensile and impact properties
are verified by destructive testing of a tool joint representing each
process batch. Every tool joint is subjected to wet magnetic particle
inspection, both transverse and longitudinal, to insure the absence
of defects.

heat treatment is monitored
and recorded in a strip chart.
Each weld is 100% inspected
for hardness to confirm that they were adequately tempered. The
post weld heat treatment process consistently produces stronger,
tougher, and more uniform weld properties and a desirable
microstructure, which maximizes the resistance to stress and fatigue.
Surfaces adjacent to the weld line are smooth finished on both the

Tool Joints are attached to the drill pipe tube by friction welding to
produce a high integrity solid state weld connection between the
tool joint and the upset drill pipe tube. The process involves the
rotation of one surface against a second surface at a relatively
high speed and under heavy pressure. The friction between the
tool joint surface and the pipe surface generates heat, causing the
contact surfaces to reach a high temperature, below the melting
temperature, at which they are forged together, producing the
weld. Every weld is monitored and recorded in a strip chart.

The Quality Control involves sampling at defined and random
intervals for process control.
All the tests and inspection

The OD and ID weld rams are removed by shearing and machining.
Post weld heat treatment of the heat-affected zone between the drill

Traceability
For each drill pipe component,
complete product and process
traceability is maintained from the raw
material to the completion of all the
manufacturing. For the pin and box
tool joints, the mill test certificates are confirmed by incoming
testing and each tool joint is provided with a unique product
number and this product number gives the traceability through out
the manufacturing process. The same procedure is applied to the
pipe for it’s traceability.

HEAVY WEIGHT DRILL PIPE
OCTL Heavy Weight Drill Pipe consists of two extra long tool joints
and one central heavy wall tube. The tool joints are friction
prevent fluid cutting and two 3” wear pads on central upset to
prevent wear on the pipe section. The hardbanding is completely
welded to the central heavy wall tube. The tool joints are
manufactured from AISI 4145 H modified material, fully heat
flush on both tool joints and l” oversize on the central upset
(fully flush on request). Hardbanding materials include crushed
treated to 285 – 341 Brinell hardness and 40 ft-lbs. minimum
Charpy V-notch Impact strength. All other physical properties
sintered tungsten carbide of 14-24 mesh, Arnco 100 XTTM, Arnco
200XTTM, Arnco 300XTTM, Armacor-MTM, and TCS 8000TM or TCS
conform to API Specification 7-1. The central heavy wall tube is
manufactured from AISI 1340 steel or equivalent.

Features
Quality Control
●
OCTL Heavy Weight Drill Pipe is manufactured in compliance
A rigorous quality assurance program is maintained at every
with API Specification 7-1 and API RP 7G.
● Bore Back on Box ends and API Stress Relief Groove on Pin
manufacturing step. Each Heavy Weight Drill Pipe joint is fully
inspected by an ultrasonic unit full length. The Mechanical
ends are standard for all sizes.
● Thread roots are cold worked on all sizes for durability.
Properties, dimensions, and thread inspections are recorded on the
Inspection Certificate. Every connection is 100% dimensionally
●
All connections are phosphatized to help prevent galling during
make-up, coated with API thread compound and provided with
pressed steel or cast steel thread protectors with lifting bails.
●
To optimize wear resistance, hardbanding is standard on tool
joints 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

Tubing Manufacturing Schedule
for Threaded & Coupled Tubing
for Integral Tubing
TUBING
OCTL offers the complete range of API Tubing
including Integral and Threaded and Coupled
(non-upset and external upset with 8 Round or 10
Round APIconnection), from sizes 2 m" OD to 4
½” OD in all grades according to API
Specification 5CT and also Premium Connections.
The Premium Connections include Two Step Premium Connections including RTS-6/
RTS-6PR/ RTS-8/ RTS-8PR/ RSU-6/ RSU-8 and many other Premium Connections
that are licensed to OCTL from time to time. OCTL takes pride in being a source for
Premium Connections of high quality with a competitive edge, besides offering
repair facilities for the Premium Connections.
The finest quality steel is used for the manufacture of Tubing. Each step of the
manufacturing process is performed with the highest degree of accuracy to meet or
exceed API Specifications as well as the Industry Standards.
Plain End Pipe and Coupling Stocks in green condition (un-heat treated) are
procured to specific metallurgical chemistries and dimensional requirements as per
OCTL Metallurgical Specifications from reputed API Approved Mills only. Plain End
Pipe is upsetted (where required) and heat-treated by Quench and Temper process.
Each Heat Lot is tested for mechanical properties. The heat treated Tubing is 100%
inspected non-destructively prior to threading. The Coupling Stock follows the same
process prior to threading.
The threading on the Pipe and the Couplings is done on CNC machines and 100%
gaging of all the critical dimensional parameters is done and recorded as part of
the manufacturing records. The finished Couplings are given antigalling treatment
(Zinc or Manganese) prior to Buck-on operation. There is an on-line antigalling
treatment facility with tilt tables and phosphating tanks for both ends of Premium
Tubing. Computerized Torque Moitoring System is utilized for Buck-on operation.
The Couplings are Bucked-on to the pipe at their specific designed buck-on torques
which are recorded. All Tubing are subjected to Hydrostatic Testing as required by
API Specifications.
Internal Plastic Coating of Tubing can also be provided at customers’ option. The
finished Tubing is externally coated with rust preventive varnish, installed with
Thread Protectors and Skid Bundled with utmost care. Complete documentation is
provided with each shipment detailing the full Quality Control records.

CASING PLUS® : for a very hard but smooth surface that
Reconditioning of Drill Pipe
simultaneously protects both the tool joint and the casing in
which it is run.
Reconditioning of Drill Pipe involves full pipe body inspection as per
the guidelines of API RP7G, inspection of Tool Joints and inspection
of the critical area covering the weld zone and the internal fade out
area from the upset to the pipe body.
The worn out and damaged tool joints are cut off and new tool joints
are friction welded to the accepted pipe, machined and post weld heat
treated, hardness tested and inspected using wet magnetic particle
inspection and ultrasonic methods. The new tool joints can also be
provided with Hardfacing.
Rethreading of Drill Pipe/ Heavy Weight Drill Pipe/ Drill Collars
Rethreading involves the machining of the damaged Pin or Box and
cutting new threads in accordance to API Specification 7-1, subject to
availability of Tong Space.
ARNCO 100XTTM, ARNCO 200XTTM, ARNCO 300XTTM : Provides low
coefficient of friction to reduce casing wear, as well as provide a
high resistance to rapid abrasive wear on the tool joint.
ARMACOR MTM : Provides a low coefficient of friction and high
wear resistance to prevent casing wear as well as abrasive wear on
the tool joint.
TCS 8000TM : Chromium- alloy hardbanding material reduces wear
on tool joints and on well casings.
TCS TitaniumTM : Contains Titanium- carbides which are harder
than Tungsten- carbides increasing tool joint protection and is
casing friendly.
Make and Break of Tool Joints
Rethreading of Casing and Tubing
Break the joints in by making up three times to their
recommended make-up torque. This option ensures proper initial
Rethreading of Casing and Tubing involves inspection of the pin
threads and the couplings for thread damages. The defective pins are
make-up of tool joints which affects the life of the tool joint
connections. Saves rig time.
cut off and new pin connections are machined and the damaged
couplings are replaced with new couplings. The pipe is hydrostatically
tested as per the API Specifications.
Field Inspection
Field Inspection of Oil Country Tubular Goods as per the API
Specifications and Customer requirements is part of OCTL activities.
Internal Plastic Coating
Internal Plastic Coating of Drill Pipe improves the performance and
life of the drill pipe.
The Drill Pipe is thermal cleaned and the internal surface is blasted
with grit for a good anchor pattern preparatory to Coating. A two
stage application of phenolic / epoxy liquid coatings is sprayed on to
the internal surface of the drill pipe in a controlled manner and
thermal cured at each stage. This ensures uniform coating thickness
and Quality throughout the length of the Drill Pipe.
