New Drill Pipe Make Up Procedure

Proper initial make-up is probably the most important factor affecting the life of the tool joint connections.

Here are some recommendations to follow:

1. Proper make-up torque is determined by the connection type, size, OD and ID and may be found in torque tables

2. Make-up connections slowly, preferably using chain tongs. (High speed kelly spinners or the spinning chain used on initial make-up can cause galling of the threads.)

3. Tong them up to the predetermined torque using a properly working calibrated torque gauge to measure the required line-pull.

4. Breakout, clean, visually inspect, re-dope and (repeat 1-3). Always use the backup tongs to make and break connections.

5. Stagger breaks on each trip so that each connection can be checked, re-dope and made up every second or third trip, depending on the length of drill pipe and size rig.

A new string of drill pipe deserves good surface, handling equipment and tools. Check slips and master bushings before damage occurs to the tube.

Do not stop the downward movement of the drill stem with the slips. This can cause crushing or necking down of the drill pipe tube. The drill pipe can also be damaged by allowing the slips to ride on the pipe during trips out of the hole.

Always use back-up tongs to make and break connections and rotate breaks when tripping.

Good rig practices will help eliminate time-consuming trips in the future, looking for washouts or fishing for drill pipe lost in the hole.

Comment by Odion Ikhajiagbe on April 20, 2011 at 1:04pm: Hi guys,

Please can someone explain to me why we could have new 5 drill pipe with double shouldered tool joint (DSTJ50) with crack at box upset area considering the fact that we had only run in hole for the first time.

Fact; the pipes had only been used for drilling operation except for the fact that at some point we used them as push pipe we had a fish in hole.

Comment by Adrian Hadley on April 20, 2011 at 4:57pm: Something else to watch for when making up Double Shouldered connections, make sure the secondary shoulder (torque shoulder) is being cleaned and doped. I see a lot of rigs just doping the threads. The Torque Shoulder, at the bottom of the pin seems to be especially neglected. Not cleaning and doping both shoulders may contribute to high breakout torque.

Comment by solberg on April 20, 2013 at 11:16am: What about choice of pipe dope? Lead, copper, zinc, other? How does the type of pipe dope affect torque and thread life?
