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

Entry @ -24% requires 40’ to level off
Open Pit Danger
Never enter “any” pit with live drill string (machine must be shut off!)
Keep all rigging to a minimum
Use proper slings, duct pullers, shackles and swivels.
