That is a refacing rate of about under 10% and reject rate for machine shop recuts due to mechanical damage of under 1%. Command Tubular is a manufacturer of Standard API Connections and provides American Petroleum Institute (API) certified connections in a variety of pipe lengths, diameters and steel grades licensed for: In addition to industry API tool joint connections, Command Tubular offers its advanced CET and CDS connections when higher torque is needed. It is much less susceptible to shock and vibration than bearing stages. Standard makeup torques in PAC drill collars cause a pin neck tensile stress of 87,500 psi, compares to 62,500 psi in a similar sized NC connection. 127 0 obj <>stream VAM Services 2 0 obj 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.

D-Link DSL-2640B Router Port Forwarding Instructions As is common for all threaded connection types, RSC's are designed with a single purpose in mind, namely drilling. 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. In this post I will deal with the drill string connections only. 4.5 Drill Pipe Range III - DS40 Connection. Grade E D/P has a yield strength of 75,000 psi. The load flank which once the connection is made up takes all the load along with the torque shoulder(s). The result is that drilling tools arent being inspected as often as they used to be allowing minor mechanical damage to get worse. Tool joints are mainly screw-type connectors that join the individual joints of D/P. On a high torque connection There is an additional torque shoulder/mechanical stop at the end of the pin and back of the box. There was no additional damage to the connection. 780 0 obj <> endobj View Your Quote.

It is an NC pin with a rounded-out thread ank that gives a root radius of 0.057 inches (compared to the NCs 0.038 inches). 35 likes. Tool joint upset type is a part of the drill pipe specifications (specs). With millions of feet of drill pipe using Delta connections in the field, hundreds of wells drilled on land and offshore, and hundreds of thousands of individual connection inspections confirming its ruggedness, Delta is able to benefit your drilling operations while lowering your cost of ownership. I also have the capability to reface DS40 and CET43 connections using custom built refacing tools from Tubular inspection Products that are based on the Drilco tool. You can see the threads are all pushed back towards the seal signifying there has been to much weight put on the connection when being spun in and out. These are single shoulder connections: They only have one torque shoulder on both pin and box. These rates are pretty well what I see on all the rigs I do inspections for on a regular base. %PDF-1.6 % rMD`i1yL+GW;pV{}M>T]^TO%Kec Z;fttQSJrVj v4[T]_>O(AzzZ+VDjSM2"u~6~a~ C_L0V]?6u]QUSeyHVU>}S?rmVX'|, \yMDmjh9S+};zYfDu2o2c9Enu|/b{nA/*ed3cFIDe4. That is a legitimate question. 3 0 obj If it is then you will see stretched pin threads and belled boxes. In order for this to work the thread profiles need to match each other. Yes, some connections go together with other types under given circumstances. They offer good clearance, but often at the price of alarmingly low tensile and torsional capacity. 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 startxref They come in differentshapes and sizes from the many competing factories. In normal situations the thread wear would show a rounded thread crest and uniform wear. XPC Extreme-Profile Single Shoulder Connection 0000001728 00000 n 5,295 were here.

Now lets understand what is the main items that describe any drill pipe :if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'drillingmanual_com-medrectangle-4','ezslot_18',633,'0','0'])};__ez_fad_position('div-gpt-ad-drillingmanual_com-medrectangle-4-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'drillingmanual_com-medrectangle-4','ezslot_19',633,'0','1'])};__ez_fad_position('div-gpt-ad-drillingmanual_com-medrectangle-4-0_1');.medrectangle-4-multi-633{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:15px!important;margin-left:auto!important;margin-right:auto!important;margin-top:15px!important;max-width:100%!important;min-height:250px;min-width:250px;padding:0;text-align:center!important}. EPI is a tax-deductible U.S. 501 (c) (3) nonprofit charity. Our goal is, quite simply, to connect the lesbian community worldwide. 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. 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). PDF DRILL PIPE PERFORMANCE DATA SHEET - Complete Group With the advent of horizontal drilling and the use of top drives there have been two major changes in drilling tool damages. This is also a relatively new patented connection. This savings reduces tripping time and helps bring forth first oil, earning money for the operator and making a drilling contractors rig more attractive.
