As the pin and box connections are being screwed together in theory there should be no weight or tension on the connection. Below are photos of a DS40 pin connection that I completed minor repairs on and then was subsequently used to drill four horizontal wells. The GPDS and EIS design also provides a true flush ID through the mated tool joint assembly. PAC connections continue to be very popular for 2-3/8 inch drill pipe as well as small diameter drill collars.

With regularly scheduled field inspections of your bottom hole assembly that includes minor repairs to threads and seals there is no reason why a string of drilling tools shouldnt last until the drilling program is complete with minimal rejects. Every time that seal is refaced takes life away from that connection. In these scenarios the API box typically has a bore back (BB). Command Tubular supports all of its connections around the world by providing quality support, local licensees for repair and accessory manufacturing. To start the conversation again, simply ask a new question. These are single shoulder connections: They only have one torque shoulder on both pin and box.

With more relaxed inspection criteria and 50% more opportunity to reface the connection, Delta shows a very low recut rate and requires 30% less material to recut the connection. Regulars continue to be the connections for BHA components, even though they are inferior to NCs of the same bending strength ratio because they have a sharper root radius. The load flank which once the connection is made up takes all the load along with the torque shoulder(s). - Be LIBERAL with the thread compound in the box, the base of the box, and on the pin using a copper-based or a compatible thread compound. The number serves no real purpose other than identification because drill pipe does not have API regular connection. Built for durability and performance by the industry's leading drill pipe manufacturer, Supporting our customers is our highest priority. The D/P is inspected periodically to detect cracks, pits,reduction in wallthicknessandother defects. Faster drilling. Although similar to other API connections, these connections incorporate an internal secondary torque shoulder. They were originally a proprietary product of Hughes Tool Company and are easily recognized by their shallow 90 degree thread angle. PDF DS Connections - rdt-usa.co They offer good clearance, but often at the price of alarmingly low tensile and torsional capacity. Every day, the oil and gas industrys best minds put more than 150 years of experience to work to help our customers achieve lasting success. Get help by chat, email or phone. To narrow it down further we are going to look at Rotary Shouldered Connections (RSC). Once the opposing seals/primary torque shoulders and thread load shoulders on the pin and box connections come into contact with each other torque is then applied until recommended makeup torque is achieved. Allows D/P with a minimum wall thickness of 65% with all wear on one side so long as the cross-sectional area is the same as premium class, that is to say, based on notmore than 20% uniform wall reduction. x}[se%r,TN94)QyQ6$h}~F5>WW/=}b`FV>Oo>Qz8l ydjPD=dpGop&1_;c!o^CeCN?>}A&5+ A=}g8}  .?B>y~;A VQidaeyt#.#vWW/3MqqCw 3str{Oz\igxKwx6H'J'Gqp1Qp'4>ajZFdcFMq0w.e^WZe~,LG[?4`. >s. <> It is also my observation that if you can keep a connection in the field working the thread flanks and torque shoulders will harden up from the cold working that occurs every time the connection is made up making them more resistant to mechanical damage. 3 0 obj Only in rare circumstances can you screw together two different types of premium connections . Tool joints are mainly screw-type connectors that join the individual joints of D/P. Rejected a total of 12 subs (mostly saver and drill thru subs), 3 drill collars, and 5 hevi-wate drillpipe for excessive thread or seal damage. . I HAD FOLLOW A COMPANY RECOMMENDATION FROM THE WEBSITE TO USE SILEX NETWORK ADAPTOR, I STILL UNABLE TO PRINT ANY IMAGE FROM THE PC TO THE DS40 PRINTER. Inspection methods include electromagnetic inspection of pipe body to locate cracks and pits, sonic inspection to measure wall thickness, visual inspection to detect mashes and caliper measurements. This provides a bigger shoulder area, thus allowing a higher makeup torque. I completed a total of 34 inspections which resulted in the inspection of 650 6 1/2drill collars and miscellaneous subs and 546 4 1/2 (DS40) hevi-wate drillpipe. In summary, the Delta connection offers: Extreme torque (with as much as 20% more than XT) for drilling more extended-reach wells Enhanced hydraulics (~30-40% reduction in pressure losses compared to API) to promote faster drilling with more downhole tool power and improved hole cleaning 0000113012 00000 n At the same time, API declared that the IF and Full Hole (FH) lines were obsolete. uGPDS is an enhanced version of the GPDS connection that enables either higher torque capacity or further enhanced hydraulics. In general, D/Ps joints are available in three length ranges: API Drill Pipe Specifications (specs) is generally described 6 items. Safety Joints - TTS Drilling Solutions Thread stretch is a normal part of making up any rotary shoulder connection as long as the point of elasticity is not passed. Videos. AC3000 High Power Wi-Fi Tri Band Router. 0000057067 00000 n 802.1X. With the same outside diameter and inside diameter, our DT connection torque capacity is about 40% higher than the API connection. We have the people, capabilities, and vision to serve the needs of a challenging and evolving industry. 0000112877 00000 n Stress reliefs in the tools minimize bending loads on the break point allowing high flexibility. The CDS connection can be made up with API numbered connections and some other available double shoulder connections. On the pin the first three or four starting threads and the final two threads near the seal and on the box the first two threads near the seal and the last three or four vanishing threads at the back of the box are not engaged (high torque connections designed with less thread taper have more engaged threads). <> The same drill pipe with a CDS40 connection will have a premium minimum OD of 4 3/4. In addition, monitoring of the first 108,000 connection inspections showed Delta requires 3.1 times fewer recuts than XTmeaning cheaper repair bills, fewer pipe movements for repair, and simply less pipe needed as contingency. Management. The CDS connections life is extended by being able to wear to a smaller OD while maintaining a torsional capacity greater than 80% of the drill pipe tube. Contact Support. As Voltaire so eloquently put it: "One day everything will be well, that is our hope. 58 0 obj <>stream That is a refacing rate of about 2% and reject rate for machine shop recuts due to mechanical damage of less than 1%. See the list below for thread types that can be used together. These premium connections have the same thread profile as the corresponding API connections. The classes are summarized as follows:New:No wear and has never been used.Premium:Uniform wear and a minimum wall thickness of 80% of original wall thickness.Class 2:Allows D/P with a minimum wall thickness of 65% with all wear on one side so long as the cross-sectional area is the same as premium class, that is to say, based on notmore than 20% uniform wall reduction.Class 3:Allows drill pipe with a minimum wall thickness of 55% with all wear on one side.Api drill pipe specifications (Wear Classification), Please consider that any articles or Ads here related to Forex, Banking, any Adult sites & any Dating Websites are haram.

As an example a 4 G105 15.7 lbs/ft drill pipe with 5 x 2 7/16 NC40 connections has a premium class minimum OD of 5. That means that they have an extra torque shoulder in the nose of the pin and in the bottom of the box. The GPDS and EIS connections increased torsional strength enables tool joint dimensional optimization more suitable for the pipe body torsional strength. Examples of this are Vam Eis, DSTJ, GPDS, etc. Choose the Dynamic IP Address option from the WAN Settings pull-down menu. 0 In Michigan for a project and working across multiple universities.
