Drill Pipe
Use Caps and Plugs
Before transporting in dusty conditions or prolonged
storage, install caps and plugs to male and female
ends of pipe and to saver sub.
Replace Worn SaverLok
®
Body
Because each pipe comes in contact with the SaverLok body, check SaverLok body regularly for wear.
Compare condition of SaverLok body threads to condition of your drill pipe threads. Replace SaverLok
body any time when its thread condition is not better than thread condition of your drill pipe. Failing to
replace SaverLok body will result in damaged drill pipe. See “Change Auto Lubricator Pail” on page 235 for
replacement procedure.
Precondition a new SaverLok body the same way you do new pipe. See “Precondition New Pipe” on
page 171.
Rotate Pipe Order
Because the lead drill pipe is in the ground longer, it is subjected to higher shock loads and experiences
more wear. To help spread this wear evenly over all pipe, move the lead pipe from the previous job to the
back of the string, and move every other pipe forward one position.
