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.
IMPORTANT: The first pipe drilled must be
in a straight line with the unit. A misaligned
pipe can damage threads on each pipe that
is added.
NOTICE: Clamping anywhere else on the
pipe will weaken the pipe. Pipe can later
break, even when operating under normal
loads.
