It is my experience that the majority of seal damage is usually much less than .031 deep allowing for several refacings. Command Tubular is a manufacturer of Standard API Connections and provides American Petroleum Institute (API) certified connections in a variety of pipe lengths, diameters and steel grades licensed for: In addition to industry API tool joint connections, Command Tubular offers its advanced CET and CDS connections when higher torque is needed. That rule shouldnt be taken literally and the minimum amount of material should be removed in a single refacing. I refaced a total of 66 seals. To narrow it down further we are going to look at Rotary Shouldered Connections (RSC).

Makeup Torque Guidelines - Good COPPER-BASED thread compound is recommended for rotary-shouldered drill pipe connections by the OEM. High-strength connections designed for demanding drilling applications. In normal situations the thread wear would show a rounded thread crest and uniform wear. Let's take a look at how this works. With millions of feet of drill pipe using Delta connections in the field, hundreds of wells drilled on land and offshore, and hundreds of thousands of individual connection inspections confirming its ruggedness, Delta is able to benefit your drilling operations while lowering your cost of ownership. 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. %PDF-1.5 The actual weight of the 5 D/P in the above example is 20.89 lb/ft. WEP Settings or WPA Settings: Enter the wireless connection's security key. 0000038534 00000 n Standard makeup torques in PAC drill collars cause a pin neck tensile stress of 87,500 psi, compares to 62,500 psi in a similar sized NC connection. %%EOF GPDS and EIS are not interchangeable with each other. I completed a total of 12 inspections which resulted in the inspection of 166 6 1/2drill collars and miscellaneous subs and 430 4 (DS40) hevi-wate drillpipe. This allows smoother fluid flow with minimized turbulence and energy loss inside the connection. They offer good clearance, but often at the price of alarmingly low tensile and torsional capacity. Our family of companies is organized to provide expert solutions, equipment, and operational support to optimize your drilling and production operations. 0000038446 00000 n Grant Prideco Double Shoulder and EIS connections offer enhanced performance and interchangeability with API rotary-shouldered connections.

They were originally a proprietary product of Hughes Tool Company and are easily recognized by their shallow 90 degree thread angle. 8aeZH PjAN% s|Tr"D|ax:h w NXC?NGXP@{f*$L@wEyWg{\k~c]XIGU1j+\gBD[ lPthp8. Top drives are several times heavier than the old rotary table rigs swivel and kelly bar. 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. Also, the 6-5/8 FH was officially reinstated in 1993, no doubt because of its increasing popularity on 6-5/8 inch D/P. Management. Delta delivers improved overall performance compared to our XT connection but with the ease of use and lower cost of maintenance of an API connection.
