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.

Oil Country Tubular Ltd.
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.
Threads are precision machined on CNC lathes. All connections
are 100% inspected for thread parameters and phosphatized either
with Zinc or Manganese for antigalling treatment.
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 OD and ID weld rams are removed by shearing and machining.
Post weld heat treatment of the heat-affected zone between the drill
pipe upset and the tool joint is carried out to restore the properties of
the weld zone. The post weld heat treatment is a Quench and Temper
process by which the weld zone is first brought to its
austenitizing temperature,
and then polymer quenched.
An area wider than the weld
zone is then re-heated by
induction to tempering
temperature. Every post weld
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
OD and ID. Precision machining and grinding provides a surface
finish that is free of stress risers. Each weld area is 100% inspected
using wet magnetic particle and ultrasonic inspection techniques.
Destructive testing of the weld covering tensile, yield, impact and
bend tests are carried out for every defined lot and are
documented.
The Quality Control involves sampling at defined and random
intervals for process control.
All the tests and inspection
results and product traceability
data are fully documented and
maintained in a computerized
data base. At any time, the
Customer can be provided with
a comprehensive account of
his product.
DRILL PIPE
TraceabilityFor 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.
Complete documentation is provided with each shipment detailing
the full Quality Control records covering,
● Quality Clearance Certificate
● Length Tally Sheet
● Drill String Assembly Data, which includes the product number
of each component (Pin and Box and Pipe), heat numbers of
each component, finished length, upset to upset length & weight

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.
The finished Drill Pipe is externally coated with rust preventive
varnish, attached with Thread Protectors and Skid Bundled with
utmost care.

DRILL COLLARSOCTL Drill Collars (Slick and Spiral) are manufactured from AISI 4145
H Chromium Molybdenum Alloy Steel and are fully heat treated to a
Brinell Hardness range of 285-341 BHN and have a minimum Charpy
V-notch Impact strength of 40 ft-lbs. at 70° F and a minimum elongation
of 13%. The mechanical properties meet or exceed API Specification 7-1,
requirements. The physical properties are guaranteed one inch below the
surface at ambient room temperature.
CNC Machines. All API connections comply with dimensional requirements
specified in API Spec 7-1 and guidelines presented in API RP 7G.
The thread roots as well as elevator and slip recess upper radii are
systematically cold rolled to improve fatigue resistance of the
connections by minimizing crack initiation. To improve resistance to
galling all connections are phosphatized and coated with an API
thread compound. The connections are provided with pressed steel
or cast steel thread protectors.
Spiral Drill CollarsTo avoid differential pressure sticking in the hole, the surface of
drill collars can be provided with three spiral grooves reducing the
contact area with the wall of the hole. The spiral grooves let mud
circulate freely around the Drill Collar to equalize pressure and
prevent a seal from forming. Loss of weight is approximately 4%,
compared to Slick Drill Collars.

API Stress Relief Features and API Bore
Back Box decrease the frequency of
fatigue failures by improving the bending
strength of pin and box connections,
thereby, reducing high stress
concentrations. Stress relief features are
machined in compliance with API
Specification 7-1. Connections NC23, NC
26 (2 m IF) and NC 31 (2 o IF) do
not have sufficient metal to accommodate
stress relief features.
Slip and Elevator recesses improve
handling efficiency and safety. The
upper radius of the elevator recess is
cold-rolled. Slip and Elevator recesses
can be used together or separately. Slip
and Elevator Recesses are machined in
compliance with API RP 7G guidelines.
On enquiries and orders, please specify:Outside Diameter, Bore, Length, Connection Size and Type, API Stress Relief Features on Pin and Box ends, Slick or Spiral,Hard banding (band location and width), Slip or Elevator Recesses, Pressed or Cast Steel Thread Protectors, and any special features.

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

The Premium Connections include RFC Flush OD Liner and RSS IntegralJoint Casing, in addition to many other Premium Connections that arelicensed to OCTL from time to time. OCTL takes pride in being a sourcefor Premium Connections of high quality with a competitive edge, besidesoffering repair facilities for the Premium Connections. The facility includesSwaging and Expander required for certain Premium Connections.
The finest quality steel is used for the manufacture of Casing. Each stepof the manufacturing process is performed with the highest degree ofaccuracy to meet or exceed API Specifications as well as the IndustryStandards.
Plain End Pipes and Coupling Stocks in green condition (un-heat treated)are ordered to specific metallurgical chemistries and dimensionalrequirements as per OCTL metallurgical Specifications from reputed APIApproved Mills only.
Plain End Pipe is upsetted (for Extreme Line Casing only) and heat-treatedby the Quench and Temper process. Each Heat Lot is tested for mechanicalproperties. The heat treated Casing is 100% inspected non-destructivelyprior to threading. The Coupling Stock follows the same process prior tothreading.
The threading on the Pipe and the Couplings is done on CNC machinesand 100% gaging of all the critical dimensional parameters is done andrecorded as part of the manufacturing records. The finished Couplings aregiven antigalling treatment (Zinc or Manganese) prior to Buck-on operation.
The Couplings are Bucked-on to the pipe at their specific designed buck-on torques which are recorded.
All Casing are subjected to Hydrostatic Testing as required by APISpecifications.
The finished Casing is externally coated with rust preventive varnish,attached with Thread Protectors prior to shipment.23

SERVICESServices include Tool Joint Hardfacing (SmoothX®/ Super SmoothX®/
CASING PLUS®/ ARMACOR MTM/ ARNCO 100XTTM, ARNCO 200XTTM,
ARNCO 300XTTM/ TCS 8000TM/ or TCS TitaniumTM), Make and Break
of Tool Joints, Internal Plastic Coating of Drill Pipe and Tubing,
Reconditioning of Drill Pipe, Re-threading of Drill Pipe, Heavy Weight
Drill Pipe, Drill Collars, Tubing and Casing and Field Inspection.
Reconditioning of Drill Pipe
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.
Rethreading of Casing and Tubing
Rethreading of Casing and Tubing involves inspection of the pin
threads and the couplings for thread damages. The defective pins are
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.
Tool Joint Hardfacing
SmoothX® : provides a smooth surface with little or no exposed
carbide to minimize the tool joint wear.
Super SmoothX® : for applications requiring maximum casing
protection provided by a “machine or grind finish” surface.
CASING PLUS® : for a very hard but smooth surface that
simultaneously protects both the tool joint and the casing in
which it is run.
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
Break the joints in by making up three times to their
recommended make-up torque. This option ensures proper initial
make-up of tool joints which affects the life of the tool joint
connections. Saves rig time.
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.
