Drill Pipe

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.
NOTICE: Clamping anywhere else on the
pipe will weaken the pipe. Pipe can later
break, even when operating under normal
loads.
