Custom screen DPM-DS pin and box connection made up to a smooth bore, without gap or change in ID transition at the secondary make-up shoulder. One thing I do though is when it comes to galled seals with raised burrs that do not meet the requirements to be refaced, manufacturers recommend not filing the gall flat but to reface the seal instead (raising repair costs). 0000112955 00000 n Team uniforms and spirit wear. Theme by Seos Themes. 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. 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). endobj SST boxes are identical to NC boxes of the same size. 5 Drill Pipe Range II - NC50 Connection. Available drill pipe, heavy-weight drill pipe and collars in all sizes from 2 3/8-12.drillstrings and frac strings. In normal situations the thread wear would show a rounded thread crest and uniform wear. 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. Both connections offer a versatile alternative to standard API connection designs when higher operational torque and tool joint wear allowance are desired, and they are fully interchangeable with corresponding API NC or FH counterparts. Refacing should be a last resort when repairing minor seal damage. Although similar to other API connections, these connections incorporate an internal secondary torque shoulder. Contact your Grant Prideco representative about our uLtimate Series connections for more detailed information. <> All this damage is being caused on the drilling floor and by evaluating the mechanical damage to connection threads and seals you should be able to determine the cause of the mechanical damage and make corrections. %PDF-1.6 % The drill string data sheets tell us what the pipe can endure internally in the drill string before it bursts or collapses. 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.

The load flank which once the connection is made up takes all the load along with the torque shoulder(s). 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. 0000001396 00000 n <]/Prev 117280>> Only comedy club in town with the nation's top comedians PROVEN to make you laugh! Sometimes these are experienced drillers who have been in the industry for years. Removed 1 cracked drilling tools from service. In this post I will deal with the drill string connections only. Top drives are several times heavier than the old rotary table rigs swivel and kelly bar. This additional strength provides the required torque for drilling to extended depths or in more demanding environments. However, the 5 1/2 FH was officially resurrected about 10 years later. It is much less susceptible to shock and vibration than bearing stages. 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; So here comes a post with the need-to-know basic stuff about drilling connection types. With the Technology on todays high tech drilling rigs specifically designed to make up and break out drilling tool rotary shoulder connections you shouldnt see the number of rejected tools going to machine shops for thread and seal repairs that you do. <>/Metadata 932 0 R/ViewerPreferences 933 0 R>> It is also a good idea to monitor the damage to the top drive saver sub working pin it will tell you if there is a problem by its wear pattern.

Tool joints are mainly screw-type connectors that join the individual joints of D/P. I won't be talking about connections for casing or tubing. The majority of damage today is caused by external wear. 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. 24 Connection mode Description Wi-Fi Connects to a Wi-Fi router (requires additional network setup steps, see link at end of topic) 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. %PDF-1.7 Thanks to the financial capital provided by our investors, we're able to continue developing innovative products and solutions to the oil and gas industry that lead a safer, more environmentally friendly future.

The result is that drilling tools arent being inspected as often as they used to be allowing minor mechanical damage to get worse. As the grade (minimum yield strength) increases the actual weight increases because the upset has more metal in it. 4 threads per inch (.250 lead) . I refaced a total of 66 seals. If it is then you will see stretched pin threads and belled boxes. Also, the 6-5/8 FH was officially reinstated in 1993, no doubt because of its increasing popularity on 6-5/8 inch D/P. Feel free to use this compatibility matrix as a guide when trying to figure out what goes together with what: So until a genius invents the perfect quick connection, we just have to accept the status quo and live with it.

Let's take a look at how this works. On a high torque connection There is an additional torque shoulder/mechanical stop at the end of the pin and back of the box. But why all these connection types? <> Do you need to talk with drilling experts and have a free consultion? PAC connections continue to be very popular for 2-3/8 inch drill pipe as well as small diameter drill collars. Drill Pipe; Heavyweight Drill Pipe . DIR-2640-US. There are 17 NC connections with pitch diameters ranging from 1.1/16 (NC-10) to 7.3/4 inches (NC-77). Interchangeability means that the connections will mate together, make up, and function; however, the performance properties will be limited to those of an API connection. The service provider assigns a global IP address from a pool of addresses available to the service provider. There is no apparent reason (except tradition) for their continued use, since superior NCs exist for most all applications.

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. Keep in mind for example a 4 1/2XH pin like the one bellow has over 4 meters worth of threads if they were stretched out. - 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. One the world cant live without. I determine the refaceability of a connection by referencing the pin or box bench mark and if a bench mark is not present (some machine shops dont re-apply bench marks when recutting) I measure the pin length or box counterbore length to assess refaceability.
