Clamp Pipe
Clamp on pipe when joint is centered between
wrenches (1 and 2). Always clamp on the larger
diameter areas on either side of the tool joint
face.
Turning shaft can kill you or crush arm or leg. Stay away.
To help avoid injury: Only clamp pipe at reinforced end. Clamping anywhere else on the
pipe will weaken the pipe. Pipe can later break, even when operating under normal loads.
NOTICE: Wrenches can open after engine shutdown. Ensure that any downhole tool or pipe in tool joint
vises is attached to spindle or removed before transport.
NOTICE: Clamping pipes on top of female
threads can damage threads. Only clamp
female pipe ends behind the threads.
