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). Frode Bjrheim is a specialist in drill pipe standards and lifting equipments with more than 30 years' experience in the oil & gas industry, both offshore and onshore.

dv%S. 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. That is a refacing rate of about 2% and reject rate for machine shop recuts due to mechanical damage of less than 1%. if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'drillingmanual_com-large-leaderboard-2','ezslot_10',622,'0','0'])};__ez_fad_position('div-gpt-ad-drillingmanual_com-large-leaderboard-2-0');So, the actual weight depends on the type of connection thread and pipe grade.

In summary, the Delta connection offers: With a deep stab in, more threads engaged through spinning, and a reduced tong-free length on the box tool joint OD, the Delta connection is as easy to run as an API connectiona sentiment confirmed by rig crews we visited.

The number serves no real purpose other than identification because drill pipe does not have API regular connection.

They are the load flank and the stabbing flank. 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.

Our award-winning DS40 is a compact, affordable and powerful digital photo printer that uses a high-resolution dye-sublimation processor to produce photos with impressive full-color details. In normal situations the thread wear would show a rounded thread crest and uniform wear. In general, D/Ps joints are available in three length ranges: API Drill Pipe Specifications (specs) is generally described 6 items. This did a great deal of damage and caused many washouts. 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. 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.

There are 17 NC connections with pitch diameters ranging from 1.1/16 (NC-10) to 7.3/4 inches (NC-77). Stress reliefs in the tools minimize bending loads on the break point allowing high flexibility. It is simply an NC connection with an additional torque shoulder at the pin tip. The API has established guidelines for drill pipe classification classes in API RP7G. They were originally a proprietary product of Hughes Tool Company and are easily recognized by their shallow 90 degree thread angle. Videos. 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.

In these scenarios the API box typically has a bore back (BB). Only in rare circumstances can you screw together two different types of premium connections . Although similar to other API connections, these connections incorporate an internal secondary torque shoulder. However, this is not as bad as it seems, since in drill collars PACs rarely survive tensile and torsional loads long enough to fail by fatigue anyway.

Innovative thread design Similar collar ID and OD to standard API NC connections Developed to eliminate twist offs and reduce NPT and maintenance costs associated with downhole failures, the XPC* extreme-profile single shoulder connection significantly increases fatigue life over standard API NC connections. - Ensure 360 DEGREES of coverage of the threads and torque shoulders. 0000057331 00000 n
This savings reduces tripping time and helps bring forth first oil, earning money for the operator and making a drilling contractors rig more attractive. PACs are very poor selections for drill collars. 0000057993 00000 n
This secondary torque shoulder is not a seal. On a high torque connection once torque is being applied the pin connection will stretch slightly until the secondary torque shoulders/mechanical stops come into contact with each other and then recommended makeup torque is achieved.
