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. There is no gap or change in the ID from the box to the pin, creating a smoother fluid flow with less turbulence and eliminating the opportunity for trapped cement and cuttings. The tendency for mud or cement trap in crevices are eliminated as well. 5.5 Drill Pipe Range II - HT55 Connection. Manufacturers compete for the best connection, and that will probably continue for some time. the NC-38 a GPPD of 3.80800 inches and so on. 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. 3 0 obj The number serves no real purpose other than identification because drill pipe does not have API regular connection. You can see the threads are all pushed back towards the seal signifying there has been to much weight put on the connection when being spun in and out. There is no apparent reason (except tradition) for their continued use, since superior NCs exist for most all applications. In all the years I have inspected drilling tools I have never seen a seal that has been filed cause washouts.
