At the same time, API declared that the IF and Full Hole (FH) lines were obsolete. 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). This allows smoother fluid flow with minimized turbulence and energy loss inside the connection. With the advent of horizontal drilling and the use of top drives there have been two major changes in drilling tool damages. 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. Safety Joints - TTS Drilling Solutions 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. About this Guide. PDF DP/LS Performance Sheet - Workstrings International At Odfjell Well Services we constantly hear from people who ask us why certain drill pipes don't go together. All rights reserved B.H.A. 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. Why can't we as an industry just pick the best one and go with it? Besides, the dimensions (diameter and length) of the secondary shoulder need to allow it. sz}KTnG_hFxm; =TbuxW.eqzxiy})8uXvBVv|iZJ%RsGv*CEPOBmCOxJ60zJM%J c9jh]t7gCt{VSc As the pin and box connections are being screwed together in theory there should be no weight or tension on the connection. %PDF-1.5 It is an NC pin with a rounded-out thread ank that gives a root radius of 0.057 inches (compared to the NCs 0.038 inches). l I HAD FOLLOW A COMPANY RECOMMENDATION FROM THE WEBSITE TO USE SILEX NETWORK ADAPTOR, I STILL UNABLE TO PRINT ANY IMAGE FROM THE PC TO THE DS40 PRINTER. %PDF-1.6 % ?m dv%S. This is a patented design for tool joint pins. On the other hand there were inspection companies in the past that used a grinder with a soft disc on it to flatten galls and polish seals on a regular base.

That is a legitimate question. Whenever I start scanning, the software EPSON scanner works fine but it will . Streamlined GPDS and EIS connections provide 20 to 50% more torque than API rotary-shouldered connections of the same dimensions.
