Drill Pipe
CMW
Use Drill Pipe Correctly
Align the Joints
Always carefully align the male and female ends of
pipe before screwing them together. Poor alignment
can damage the threads and destroy the usefulness of
the joint.
Clamp Pipe Correctly
Clamp on pipe when joint is centered between
wrenches. Clamp only on the tool joint of the drill pipe
as shown. This portion of the drill pipe is designed for
clamping and is considerably thicker and stronger than
the rest of the pipe.
See “Clamp Pipe” on page 92 for more information.
NOTICE: Clamping anywhere else on the pipe will
weaken the pipe. Pipe can later break, even when
operating under normal loads.
