Rig Alignment

Rig Alignment Should be

Checked and Adjusted.

Check Saver Subs Daily

Check for thread wear and rotary shoulder damage

Life-Reducing Damage

Spiral Gouging

!

Over-Tightening

Improper tightening and Over Bending

Over- Tightening Lack of tool joint compound

Exceeding Bend Radius

Tool Joints

Inner Rotary Shoulder

Outer Rotary Shoulder

Inadequate Torque

Shoulder separates when pipe is bent

Pin carries the bending load

Fretting from movement in the joint
