Make Up and Break Out Joints Correctly
• Make up and break out joints slowly. Do not ram pipes together during makeup or force them apart
during breakout. Carefully time rotation with carriage travel speed, and always connect and disconnect
joints slowly and deliberately. This will help prevent thread crossing, galling, and shoulder swelling.
• Torque joints fully. Once the joint is connected and the shoulder faces are touching, torque them to
full machine torque. Improperly torqued joints will damage the shoulder faces and threads, and will
cause joints to leak or break while drilling or backreaming.
Do not Overwork the Pipe
Never exceed the bend radius for your pipe. See “Recommended Bend Limits” on page 50. Do not
oversteer.
NOTICE: Bending pipe more sharply than recommended will damage pipe and cause failure.
