Drill Pipe Break In Procedures

When using new drill pipe for the first time, it is important to take care not to damage the threads and also to reduce initial wear.

Below are some procedures and suggestions to avoid thread problems. Most thread problems that we have encountered occur with the first couple of uses of new drill pipe.

Inspect the lower connection in the top sub to make sure the threads are in good condition. By good condition, the connection should be free from breaks and rough spots on the threads and the threads are not too worn. If you are putting on a new string or a significant number of new drill pipe, a new top sub is recommended.
Remove the thread protectors from the drill rod and clean off any tool joint compound. Inspect the connections for damage that may have occurred during transit. A damaged thread protector may be a sign of a damaged thread. Apply new, good quality tool joint compound – free from dirt or other containments.
Prior to making the connection at the table, cover the connection in the table, and blow out the drill pipe. The tubes are heat treated and thereby may contain scale. Although the scale is removed during production, more may be present from the bumps and handling during transit. Scale does not go well with DTH hammers.
Make and break the connections slowly a couple of times. These should thread together easily and only require torque during the last 1/8” or so. If there is resistance sooner, you may want to back off and inspect for damage or perhaps check your rig alignment. Afterwards, clean off the tool joint compound and inspect for damage. If OK, reapply compound.
It is recommended that extra care be taken during make up the first few holes.
