Athlete's Connection/Teamlax, Lansing, Michigan. 0000097810 00000 n 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). It is my experience that the majority of seal damage is usually much less than .031 deep allowing for several refacings. Threads have two flanks (the sides of the thread). There are 17 NC connections with pitch diameters ranging from 1.1/16 (NC-10) to 7.3/4 inches (NC-77). Theme by Seos Themes.

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. With the same outside diameter and inside diameter, our DT connection torque capacity is about 40% higher than the API connection. Drill Pipe; Heavyweight Drill Pipe . endobj As Voltaire so eloquently put it: "One day everything will be well, that is our hope. The result is that drilling tools arent being inspected as often as they used to be allowing minor mechanical damage to get worse. This secondary torque shoulder is not a seal. Similarly, the API pin will make up to the double shouldered box. - 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. These premium connections have the same thread profile as the corresponding API connections. If I see mechanical damage to threads that I believe can be prevented by adjustments on the rig floor I report this to the rig manager.
