Perform Regular Drill Pipe Care
Precondition New Pipe
Repeat this procedure three times for each piece of pipe before it is used the first time:
1. Hand-lubricate entire surface of threads and shoulders of both ends of pipe with copper base tool
joint compound. See page 120 for correct lubricant.
2. Join pipe and tighten joint.
3. Break joint.
4. Move pipe back to box.
Lubricate Joints Before Each Use
Lubricate threads and shoulders of male joints with copper base tool joint compound. This prevents rust
and reduces wear on shoulders and threads. See page 120 for correct lubricant.
Clean the Threads
Clean the threads as needed with high-pressure water and detergent.
NOTICE: Failure to follow this procedure could result in fused joints. Pipe will be damaged or destroyed.
NOTICE: Do not use gasoline or other petroleum-based solvents. This prevents tool joint compound
from sticking to the joints and will reduce thread life.
