Pup joints

Pup joints adjust the overall length of the drill string so it lands at a specific depth and positions tool joints at the rig floor or top drive. They are made either from API 5CT seamless tubing or machined from integral chromium-molybdenum alloy bars. Pup joints with tool joint OD below 6-7/8" have a minimum yield of 110 ksi; 6-7/8" and larger, 100 ksi. Lengths from 2 to 25 ft are available; standard lengths are 5, 10, 15 and 20 ft. Drill-collar-grade pup joints are not suitable for H2S service.

Thread protectors

Thread protectors should always be fitted to both pin and box when drill stem components are shipped or stored. Three types are available:

Cast steel with lifting bail (ASTM A27 Grade 60-30) – suitable for picking up and laying down drill collars with a cat line
Pressed steel – light duty, for shipping and storage
Plastic – light duty, for shipping and storage
