    After upsetting, the pup joints undergo specific heat treatment cycles (Quenching and Tempering – Q&T). This process involves heating the steel to high temperatures and then rapidly cooling it (quenching), followed by reheating to a lower temperature (tempering). This refines the grain structure, enhances hardness, improves yield and tensile strengths, and ensures consistent mechanical properties throughout the joint, especially important for sour service grades (L80, C90, T95).

  5. CNC Machining & Threading:

    The heat-treated blanks are transferred to advanced CNC (Computer Numerical Control) lathes. Here, the pipe body is machined to precise outer diameter (OD) and inner diameter (ID) tolerances, and critical threads (EUE, NUE, BTC, or premium connections) are precisely cut. This ensures seamless make-up with standard tubing/casing and robust seal integrity.

    Process Highlight: CNC machining offers unparalleled precision, ensuring thread forms, tapers, and lead are perfectly within API 5B specifications, reducing galling and improving connection reliability.
  6. Coupling Attachment:

    For threaded and coupled designs, couplings are precisely manufactured and torqued onto one end of the pup joint. Couplings are often coated with anti-galling compound before make-up.

  7. Non-Destructive Testing (NDT):

    Each pup joint undergoes comprehensive NDT to detect any hidden defects. This includes:

    • Electromagnetic Inspection (EMI): Detects longitudinal and transverse defects, wall thickness variations.
    • Ultrasonic Testing (UT): Identifies internal flaws, laminations, and inclusions.
    • Magnetic Particle Inspection (MPI): Detects surface and near-surface discontinuities, especially critical after threading.
  8. Hydrostatic Pressure Testing:

    The pup joint is subjected to internal pressure testing to a specified level, typically 80% of the minimum yield strength, for a defined hold time. This verifies the integrity of the pipe body and the threaded connections under simulated operating pressures, ensuring no leaks or structural weaknesses.

    Quality Standard: Hydrostatic testing is a mandatory final check, ensuring that each pup joint can safely withstand the anticipated wellbore pressures, adhering to API 5CT and internal quality standards.
  9. Final Inspection & Surface Treatment:

    A final visual and dimensional inspection is performed. Threads are meticulously cleaned, greased with thread compound (e.g., API Modified), and protected with robust thread protectors. The entire pup joint may undergo surface treatment like painting or coating for corrosion protection during storage and transport.

  10. Marking & Packaging:

    Each pup joint is permanently marked with essential information including manufacturer's name, API monogram, grade, size, weight, heat number, and length, ensuring full traceability. They are then securely bundled and packaged for safe shipment.
