Drill Pipe<br />
Make Up and Break Out Joints Correctly<br />
• Make up and break out joints slowly. Do not ram pipes together during makeup or force them apart<br />
during breakout. Carefully time rotation with carriage travel speed, and always connect and disconnect<br />
joints slowly and deliberately. This will help prevent thread crossing, galling, and shoulder swelling.<br />
• Torque joints fully. Once the joint is connected and the shoulder faces are touching, torque them to<br />
full machine torque. Improperly torqued joints will damage the shoulder faces and threads, and will<br />
cause joints to leak or break while drilling or backreaming.<br />
Do not Overwork the Pipe<br />
Never exceed the bend radius for your pipe. See “Recommended Bend Limits” on page 56. Do not<br />
oversteer.<br />
NOTICE: Bending pipe more sharply than recommended will damage pipe and cause failure.<br />
