Largest supplier of lacrosse equipment in Mid-Michigan. Manufacturers compete for the best connection, and that will probably continue for some time. The API has established guidelines for drill pipe classification classes in API RP7G. Hopefully it will be of use to you - whether you're a rookie or a veteran. Our goal is, quite simply, to connect the lesbian community worldwide. The minimum OD varies with what grade and weight the drill pipe is. %%EOF 5.5 Drill Pipe Range II - HT55 Connection. 5 Drill Pipe Range II - DS50 Connection. This is also a relatively new patented connection. 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. This secondary torque shoulder is not a seal. giEnk3)A[C6{:kRmzY,+D8?O.t]LG0BZ/$He$h6K?aBUJ:yW|71? 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. The number serves no real purpose other than identification because drill pipe does not have API regular connection. The first is that with the use of mud motors right from surface almost all the rotary and bending stresses have been removed from the drill string and you do not see the metal fatigue in the form of critical damage like cracks and internal sharp bottom transverse pitting rings you used to with conventional rotary drilling. FAQs. 0000023284 00000 n With more relaxed inspection criteria and 50% more opportunity to reface the connection, Delta shows a very low recut rate and requires 30% less material to recut the connection. 0000088143 00000 n 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. 0000033645 00000 n 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.

At the same time, API declared that the IF and Full Hole (FH) lines were obsolete. These are single shoulder connections: They only have one torque shoulder on both pin and box. As the most balanced drill pipe connection we have ever put to market, Delta offers a cost of maintenance comparable to that of an API connection while providing improved performance. If they do, take care to use the makeup torque values for the weakest connection. Join our global family and become part of the company thats leading innovation within the upstream oil and gas industry. Before you try to screw different connections together, do the following. But take the necessary precautions. Threads also see a lot of minor damage from mishandling and depending on the location and severity of that damage in many easily be repaired. This gives torsional capacities 40-60 percent higher than the original NC. The tendency for mud or cement trap in crevices are eliminated as well.
