The minimum strength can be converted to a more usable strength in pounds by multiplying the minimum yield in psi by the cross-sectional area of the metal. You don't want an unexpected shoulder separation and an uncontrollable leak when drilling a deviated well.. The original high-performance rotary-shouldered connections. Secondly you see much more minor thread damage now because of the shear weight of the top drive. 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. Loading Originals. There is no gap or change in the ID from the box to the pin, creating a smoother fluid flow with less turbulence and eliminating the opportunity for trapped cement and cuttings. - Ensure 360 DEGREES of coverage of the threads and torque shoulders. 5 Drill Pipe Range II - DS50 Connection. Torque advantage over API and runs easier than the competition, providing the optimum solution to reach total depth as fast as possible. Wide variety of thread connections Safety Joints Safety Joints are designed for high bending flexibility. However, here we shall mention only API drill pipe Specifications only for thread types, but we will give you simple introduction to other thread types.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'drillingmanual_com-large-mobile-banner-1','ezslot_14',640,'0','0'])};__ez_fad_position('div-gpt-ad-drillingmanual_com-large-mobile-banner-1-0'); In 1968 NC connections were introduced by API to cover a multitude of needs from macaroni tubing to 12 inch drill collars. 0 That is a refacing rate of about 2% and reject rate for machine shop recuts due to mechanical damage of less than 1%. With up to 50% faster makeup than the XT connection, Delta saves up to 4 seconds on each connection makeup and breakout. In addition to industry API tool joint connections, Command Tubular offers its advanced CET and CDS proprietary high torque double shoulder connections when higher torque is needed. That means that they have an extra torque shoulder in the nose of the pin and in the bottom of the box. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

Each joint of drill pipe consists of the tube body and the Tool Joint (connection). PAC connections continue to be very popular for 2-3/8 inch drill pipe as well as small diameter drill collars. Some premium connections are compatible with API connections, even though one of them has a double shoulder and the other not. The stabbing flank on the other hand does not come into contact with its opposing stabbing flank when made up, there is actually a space to channel away excess thread compound and debris while the connection is being made up (Rotary shoulder connections do not seal in the threads). Also you can see there was no original damage to the load flank it was all on the stabbing flank showing the previous damage was caused by too much weight on the connection at make up or break out. endobj You may delete and block cookies from this site, but parts of the site may not function as a result. It is my experience that the majority of seal damage is usually much less than .031 deep allowing for several refacings. Higher torque. Exterior wear includes OD wear, dents and mashes, slip area crushing, cuts, pitting and corrosion. The CDS connection can be made up with API numbered connections and some other available double shoulder connections. NC means Numbered Connection and the number signifies the Gauge Point Pitch Diameter (GPPD) of the connection. Also the heavier the drilling tool the more severe the damage, drill collars and hevi-wate drill pipe seeing the most thread damage. Products TSC's Drill Pipe product range includes sizes from 2-7/8" diameter pipe to 6-5/8" diameter pipe. This is a patented design for tool joint pins. 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. To narrow it down further we are going to look at Rotary Shouldered Connections (RSC). 0000104695 00000 n INSPECTION SERVICES LTD. These included the NC-50 (old 4.1/2 IF) the NC-46 (old 4.1/2 XH) and NC-38 (old 3.1/2 IF). Since downhole stress can be additive to makeup stress, PAC connections are that much closer to failure even as they pass through the rotary. 0000002034 00000 n Streamlined GPDS and EIS connections provide 20 to 50% more torque than API rotary-shouldered connections of the same dimensions. % 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. They offer good clearance, but often at the price of alarmingly low tensile and torsional capacity. Environmental Topics and Definitions Applicable to NOV, We Power the Industry that Powers the World, 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, Streamlined design to allow using larger drill pipe size, reducing vibrations for better borehole quality. Specifications The Grant Prideco Double Shoulder (GPDS) and EIS connections are high-performance rotary-shouldered tool joint connections available for drill pipe ranging in size from 2 to 6 in.

DIR-2640-US. The rule for refacing rotary shoulder connections is to remove not more than 1/32 inch(.031) from a pin or box seal at any one refacing and not more than 1/16 inch(.062) cumulatively. The number serves no real purpose other than identification because drill pipe does not have API regular connection. I have been repairing minor seal damage like this for over 30 years without issues. 0000088143 00000 n The majority of damage today is caused by external wear. Allows drill pipe with a minimum wall thickness of 55% with all wear on one side. The drill string data sheets tell us what the pipe can endure internally in the drill string before it bursts or collapses. %PDF-1.6 % These are single shoulder connections: They only have one torque shoulder on both pin and box. trailer The load flank which once the connection is made up takes all the load along with the torque shoulder(s). However, the 5 1/2 FH was officially resurrected about 10 years later. 0000009762 00000 n That rule shouldnt be taken literally and the minimum amount of material should be removed in a single refacing. Let's take a look at how this works. . 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. Theme by Seos Themes. As the grade (minimum yield strength) increases the actual weight increases because the upset has more metal in it. Manufacturers compete for the best connection, and that will probably continue for some time.

This did a great deal of damage and caused many washouts. hb``d``E01%%$QM(f`dg2e|d1C3Xfc0y;Pn7[1KQ0D04(?``8!un>7@FCOD These premium connections have the same thread profile as the corresponding API connections. In summary, the Delta connection offers: Extreme torque (with as much as 20% more than XT) for drilling more extended-reach wells Enhanced hydraulics (~30-40% reduction in pressure losses compared to API) to promote faster drilling with more downhole tool power and improved hole cleaning 0000112799 00000 n 5.5 Drill Pipe Range II - HT55 Connection. The M-DS40-XYZ Compact Metric Dovetail Linear Stage is preferred for small 14 mm XYZ travel applications where set, lock, and forget is required. It is simply an NC connection with an additional torque shoulder at the pin tip. The longer internal secondary shoul-der on the nose of pin provides additional torsional strength. This provides a bigger shoulder area, thus allowing a higher makeup torque. giEnk3)A[C6{:kRmzY,+D8?O.t]LG0BZ/$He$h6K?aBUJ:yW|71? endstream endobj 130 0 obj <>stream <>/Metadata 932 0 R/ViewerPreferences 933 0 R>> Ask your drilling equipment provider whether they permit it. description date rev. xref Each description item is explained in more detail below.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'drillingmanual_com-box-4','ezslot_8',634,'0','0'])};__ez_fad_position('div-gpt-ad-drillingmanual_com-box-4-0'); Which is simply the plain end (tube) outside diameter.
