1. What is a Tubing Pup Joint? Roles, Classifications & Key Technical Parameters

Tubing Pup Joint is a short pipe section with threaded ends, strategically used in oilfield well completions, connections, and repairs. By adjusting the total length of the tubing string or casing string, pup joints allow for easier assembly, rig configuration, and make-up operations. Key classifications include:

  • Pup Joint Oil and Gas Grade: Designed for high-pressure, high-temperature (HPHT) oilfield environments with optimal mechanical and corrosion resistance.
  • Tubing Pup Joint: Short sections for production tubing, often requiring ISO 11960 and API 5CT compliance standards.
