Drill Pipe Pup Joints, Lift Plugs & Lift Subs


LIFT PLUGS

Lift Plugs are small easy-to-handle subs that make up to the top of the drill collars. They have a lifting flange that serves as a safety stop when drill collars without elevator recesses are being tripped out of the hole. The center section of the Lift Plugs are bored out to reduce weight for easy handling.

DRILL PIPE PUP JOINTS

AOS pup joints are machined from integral bars of chromium molybdenum alloy steel heat treated to drill collar specifications. Pup joints with tool joint OD less than 6 7/8” have a minimum yield strength of 110,000 psi. Pup joints with tool joint OD 6 7/8”and larger have a minimum yield strength of 100,000 psi.

Pup joints are available in 5’, 10’, 15’ and 20’ lengths and can be ordered to match standard drill pipe dimensions. The primary use of the pup joints is to adjust the overall length of the drill string to land at a specific depth while staying within the working area of the Kelly.
