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.
