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.

5


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

of each pipe.

● Mill Test & Inspection Certificate that includes chemical analysis

for all pipe and tool joints, mechanical results of pipe and upset

and tool joints and mechanical results of test welds.

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.

HEAVY WEIGHT DRILL PIPEOCTL 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 7-1. The central heavy wall tube is

manufactured from AISI 1340 steel or equivalent.

Features● OCTL Heavy Weight Drill Pipe is manufactured in compliance

with API Specification 7-1 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 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

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 l” oversize on the central upset

(fully flush on request). Hardbanding materials include crushed

sintered tungsten carbide of 14-24 mesh, Arnco 100 XTTMTMTMTMTM, Arnco

200XTTMTMTMTMTM, Arnco 300XTTMTMTMTMTM, Armacor-MTMTMTMTMTM, and TCS 8000TMTMTMTMTM or TCS

TitaniumTMTMTMTMTM.

● Internal Plastic Coating, if required (optional).

Quality ControlA 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 PipeSpiral 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.

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.

Tubing Manufacturing Schedule


for Threaded & Coupled Tubing

for Integral Tubing

19

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.

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.

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.
