Drill Pipes with 95% Remaining Body Wall and Extra Long Tool Joints and Special Grades are alsooffered upon Customer‘s request.

Drill Pipe and Tool Joints are manufactured from the finest quality steel available. Each step of themanufacturing process is performed with the highest degree of accuracy to meet or exceed APISpecifications as well as the Industry Standards.

Plain End Pipes and Tool Joint Forgings are ordered to specific metallurgical chemistries and arematched for physical properties, welding compatibility, weld strength and product integrity.

Plain end pipe is upsetted and heat-treated full length by theQuench and Temper process to achieve uniform mechanicalproperties. The upset profile is designed to blend with the insidediameter of the pipe body with a generous radius giving asmooth transition from the thicker cross section of the upset tothe pipe body. The smooth transition minimizes the stressconcentrations.

Tool Joint Forgings are turned, bored and faced prior to heattreatment by the Quench and Temper process to produce auniform microstructure, high ductility, and other mechanicalproperties in accordance with API Specifications. The heattreatment is done under controlled atmosphere for consistentquality. The hardness of every tool joint is checked by BrinellHardness Tester and recorded. The tensile and impactproperties are verified by destructive testing of a tool jointrepresenting each process batch. Every tool joint is subjected towet magnetic particle inspection, both transverse andlongitudinal, to insure the absence of defects.

Tools joints are attached to the drill pipe tube by friction weldingto produce a high integrity solid state weld connection betweenthe tool joint and the upset drill pipe tube. The process involvesthe rotation of one surface against a second surface at arelatively high speed and under heavy pressure. The frictionbetween the tool joint surface and the pipe surface generatesheat, causing the contact surfaces to reach a high temperature,below the melting temperature, at which they are forgedtogether, producing the weld. Every weld is monitored andrecorded in a strip chart.

Long and Smooth Internal Upset TaperMiu ≥ 140mmMiu-R ≥ 300mmMeet the NS-1 requirement,the quality of production has reached the top level in the world.

For each drill pipe component, complete product and process traceability ismaintained from the raw material to the completion of all the manufacturing . Forthe pin and box tool joints, the mill test certificates are confirmed by incomingtesting and each tool joint is provided with a unique product number and thisproduct number gives the traceability through out the manufacturing process. Thesame procedure is applied to the pipe for it's traceability.

Complete documentation is provided with each shipment detailing the full QualityControl records likeQualityClearenceCertificate/Length Tally Sheet/Drill StringAssembly Data which includes the product number of each component (Pin andBox and Pipe), heat numbers of each component, finished length, upset to upsetlength & weight of each pipe/Mill Test & Inspection Certificate which includeschemical analysis for all pipe and tool joints , mechanical results of pipe andupset and tool joints, and mechanical results of test welds/Non Destructive TestCertificate. Any other documentation per Customer's request can also beprovided.

Options available on customer's request:

Make and Break of Tool Joints: break the joints in by making up three times totheir recommended make-up torque. This option ensures proper initial make-upof tool joints which affects the life of the tool joint connections. Saves rig drilling time.

Extra Long Tool Joints: to provide increased space for connection rework and fortong handling.

Cold Rolling: of thread roots to create a pre-stress compression loading conditionwhich increases fatigue life by increasing resistance to crack initiation.

Hardfacing of Tool Joints / Internal Plastic Coating.

The finished Drill Pipe is externally coated with rust preventive varnish, attachedwith Thread Protectors and Skid Bundled with utmost care.Our integrated facility gives us the 'Competitive Edge' to manufacture and supplyDrill Pipe to your complete satisfaction.

The OD and ID weld rams are removed by shearing and machining. Post weldheat treatment of the heat affected zone between the drill pipe upset and the tooljoint is carried out to restore the properties of the weld zone. The post weld heattreatment is a Quench and Temper process by which the weld zone is first broughtto its austenitizing temperature, and then polymer quenched. An area wider thanthe weld zone is then re-heated by induction to tempering temperature. Every postweld 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 postweld heat treatment process consistently produces stronger, tougher, and moreuniform weld properties and a desirable microstructure which maximizes theresistance 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 stressrisers. Each weld area is 100% inspected using wet magnetic particle andultrasonic inspection techniques. Destructive testing of the weld covering tensile,yield, impact and bend test are carried out for every defined lot and aredocumented.

Drill CollarDrill collar is made of structure steel alloy forged or rolled from AISI4145H. Processing and thermal treatment of deep-holes.The drill collar is processed and made as per Standard API SPEC 7-1.Thermal treatment is conducted over the whole length of the products toensure that its mechanic performance can meet the provisions under theStandard API SPEC 7-1. Its Brinell hardness ranges between 285 and341. And impact energy of its Charpy V-shaped notch can be 40 ft-lb at atemperature below the surface of the pipe.Traceability: During the entire process of the making of a drill collar,complete data from performance tests for the processing of each partincluding roughcast, thermal treatment and connecting thread will be keptfor reference. A separate number will be affixed to each single part.Required testing procedures:All the drill collars will be tested according to the API Standard. Testing ofsurface dimensions and ultrasonic wave and magnetic particle testingover the whole length of a product will be included.Cold forming of thread bases: Cold rolling must be done for the bolt rootand elevator recess of a drill collar. Thus, the bearing capacity of theupper radius will be increased via reducing crack diffusion to increasefatigue strength of a drill collar and extend the service life.

Phosphating or brass plating: Phosphating or brass plating will be conductedfor all screw threads to increase their corrosion resistance and avoid threadjamming of drilling tools.

DRILL COLLAR DATA

Specified Sizes

Integral HWDP:Integral heavy weight drill pipe are made of AISI 4142H - 4145H alloystructural steel. Production complies with the provisions under theStandard SY/T 5146-1997. Connector screws comply with theprovisions of the Standard API SPEC 7-1. Heavy weight drill pipe is akind of drilling tool of medium weight which is similar to the drilling rod.Its wall thickness is greater than that of the drill rod but smaller thanthat of the drill collar. The prolonged tool joint is linked to the pipe withthick walls. Generally, it is placed between the drill rod and the drillcollar during the formation of the drilling string to prevent theunexpected change in the section of the drill string and reduce fatigueof the drill rod. It can be used for directional well drilling, to work quicklywhen the torque is rather low in order to cut wear and damage ofdrilling string. As its steel performance is lower than that of the drillcollar and the contact area on the well wall is small, differentialpressure jamming is rare.

DRILL PIPE PUP JOINTS:D.P. P. J. is important drill stem component for specialdrilling or testing operations. This short drill pipesection is used tolocate the top box of the drill string at a specified distance from the rigfloor.D.P. P. J. is manufactured either from round bar or bymachining heavy wall tubing from AISI-4145 H Material.

Note: Stress relief groove as per APl-7 can also be provided upon request

Square and Hex KellySquare or Hex Kelly's are made from AISI 4145 H modified alloy bar, quenched & temperedalong its entire length to deliver dependability & long service life. This gives hardnessrange of 285-341 BHN & a minimum IZOD impact value of 40 ft-Ib, at one inch belowthe surface at room temperature. Their heavy walls allow little flexibility; joint alignmentis held to close tolerances to help eliminate “working” at the joints & minimize jointfailure. Length of the top & bottom upsets permits recutting the threads several timesfor longer life. kelly bars are inspected ultrasonically, over their full length. AllKelly's are precision-bored by trepanning to provide true bores & are drifted to APIspecifications. Kelly ends & drive sections, internal diameters & connections aremachined & controlled to API specification.

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 goodanchor pattern preparatory to Coating. A two stage application of phenolic / epoxy liquidcoatings is sprayed on to the internal surface of the drill pipe in a controlled manner andthermal cured at each stage. This ensures uniform coating thickness and Qualitythroughout the length of the Drill Pipe

Thread Galling and Fracture Preventable Technology

Stress-relief features reduce the chance of failure due to the cyclic fatigueinherent in bending.Drill collarshave an API Stress-relief Groove on the pin and a Bore BackBox which remove unengaged threads in highly stressed areas of the drill collarjoint. This leads to fewer failures as bending occurs in the smooth surfaces,which are free from stress concentrations.

All hardbanding is done specically to meet as customer’s request andspecications.

The cold working on thread roots of the Drill Collars and HWDP inducingcompressive stresses with the help of externallyloaded roller will increase life of Drill Collar by protecting against bending stressin fatigue.
