Pup Joints

The primary use of the pup joint 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.

Command Tubular pup joints are manufactured from the highest quality API seamless tubing, per API specifications 5CT latest edition and are machined from integral bars of chromium molybdenum alloy steel. Pup joints with tool joint OD less than

6 7/8” have minimum yield strength of 110,000 psi. Pup joints with tool joint OD less than 6 7/8” or larger have minimum yield strength of 100,000 psi. Our pup joints are available from 2 feet to 25 feet in lengths however, standard lengths are 5, 10, 15 and 20 feet. Additional sizes are available upon request and can be ordered to match standard drill pipe dimensions.

Note: Drill Collar Grade Pup Joints are not suitable for H2S service.

Thread Protectors

In choosing a thread protector the drill collar OD range and the drill stem component connection size and type are some of the first things to consider. Command Tubular offers pressed-steel thread protectors, plastic protectors and cast steel lifting bails.

Pressed-Steel Thread Protectors

Command Tubular’s heavy duty plastic thread protectors are fitted to drill pipe and other products to protect threads during transit and storage. Thread protectors should always be used to protect both the pin and the box connection when drill stem components are being shipped or stored at the warehouse or location. Thread protectors are available in three types:



  • Cast Steel, with lifting bail, are made from steel casting that meet ASTM specification A27 Grade 60 – 30 (60,000 psi tensile – 30,000 psi yield) and are equipped with heavy-duty bails suitable for picking up and laying down a drill collar with a cat line. Threads and shoulders are precision machined.
  • Pressed-Steel light-duty protectors are suitable for shipping and storing threaded drill stem components only.
  • Plastic light duty protectors are suitable for shipping and storing threaded drill stem components only.
