In these scenarios the API box typically has a bore back (BB). As is common for all threaded connection types, RSC's are designed with a single purpose in mind, namely drilling. Access the most up-to-date technical documents and brochures for our Grant Prideco products. 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 0000038534 00000 n All TSC API grades meet or exceed the standards. 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. The D/P is inspected periodically to detect cracks, pits,reduction in wallthicknessandother defects. %PDF-1.7 This gives torsional capacities 40-60 percent higher than the original NC. - 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. 2 0 obj Premium connections Premium connections are like cell phone chargers. This improvement is achieved at higher cost, reduced availability and sacrificed field repairability. Some premium connections are compatible with API connections, even though one of them has a double shoulder and the other not. Removed 1 cracked drilling tools from service. Management. 0000088304 00000 n 0000113251 00000 n What might come as a surprise to many is that no API RSC is pressure rated with regards to gases and liquids. 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.

The reason for their popularity habit and the belief that changing to NCs would cost more than it would be worth. That means that they have an extra torque shoulder in the nose of the pin and in the bottom of the box. OWS expands its Premium Threading portfolio in Eastern Europe, Shifting the Focus to Advanced Casing/Liner Deployment Technologies, The DrillRdillo eliminates a trip and saves client $100k, The DrillRdillo casing scraper: The story so far [Infographic], API connections (American Petroleum Institute). %PDF-1.4 % 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. It is for reference only and should not be construed as a recommendation. Command Tubulars CET and CDS connections offers technically advanced solutions for even the most demanding drilling conditions. Technical Specifications. On this page I will briefly go over the mechanics of a rotary shoulder connection and the type of damage that is found and what I believe is the cause of that damage and the actions that I take to correct that damage if possible. Thread Type Compatibility In order for two components to fit properly, thread types must be compatible. 3 0 obj 4.5 Drill Pipe Range III- Delta 425 Connection. Therefore, in this article we shall discuss API drill pipe specifications (specs), description, classification & drill pipe connection thread types. They are manufactured with a proprietary thread designed to prevent unwanted back-off failures. PAC connections continue to be very popular for 2-3/8 inch drill pipe as well as small diameter drill collars. 0 Ironically, SSTs are rarely found in BHA components where their larger thread root radius would be most bene cial. The GPDS and EIS design also provides a true flush ID through the mated tool joint assembly. <> Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. The most common damage is to see a raised burr form on the thread crest and minor galling on the stabbing flank side of the threads. 0000112799 00000 n Connection/Tube Torsional Ratio Tool Joint Connection Type DS40 OD mm Material Yield Strength MPa 896 Tensile Yield Strength kdaN OD mm 133.4 Torsional Yield Strength ft-lbs ID mm 68.3 Recommended Makeup Torque ft-lbs Pin Shoulder Angle deg 18 Pin Tool Joint Length mm 356 Box Tool Joint Length mm 356 Drill Pipe Assembly Shoulder-Shoulder Length . <>>> The GPDS and EIS connections increased torsional strength enables tool joint dimensional optimization more suitable for the pipe body torsional strength. 4 0 obj <> endobj endstream endobj 5 0 obj <> endobj 6 0 obj <>/ProcSet[/PDF/Text/ImageC]/XObject<>>>/Rotate 0/Type/Page>> endobj 7 0 obj <>stream Powered by ASTOUNDZ, 7-1 and 7-2 (ISO 10424-1:2004 and ISO 10424-2:2007), Best in class performance and optimized operational characteristics required of high torque connections to drill the well designs of today, Available on all sizes of drill pipe, heavy-weight drill pipe and collars for use on work strings, slimhole drillstrings and frac strings, 5 turns to make-up is the fastest of any high torque connection, 170% 200% of the torsional strength of API connections, Provides increased torque with the addition of an optimized secondary torque shoulder, Reduces the amount of repairs required to less than 1% per well drilled, Cuts rig NPT during tripping operations by 50% over competitive high torque connections, A smooth ID through the connection, which can be made with smaller ODs and larger IDs than standard connections while maintaining higher torque capacities.

API connections go under many names: Regular IF (Internal Flush) FH (Full Hole) NC (Numeric Connection). The API bore back box stress relief feature is standard for the box connection on Heavy Weight Drill Pipe with NC38 and larger connections, helping to extend the service life of the connection; Cold rolling the thread roots on all Heavy Weight Drill Pipe connections increases the connection's ability to resist fatigue cracking; I completed a total of 12 inspections which resulted in the inspection of 166 6 1/2drill collars and miscellaneous subs and 430 4 (DS40) hevi-wate drillpipe. Non-API Drill Pipe Connection Thread Types H-90 Connections Removed 2 cracked drilling tools from service. 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. 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}. RSC's can endure high pressures under favourable conditions. Solving Problems. That rule shouldnt be taken literally and the minimum amount of material should be removed in a single refacing.
