Products name: 2-3/8" EUE 8RD X 8FT J55 TUBING PUP JOINT PXP
Size: 2-3/8"
Thread: EUE( UP TBG)
Grade: J55
Length: 8ft
A tubing pup joint is a specialized short-length pipe segment used in petroleum engineering to fine-tune the length of tubing strings during well completion or workover operations. Its primary function is to ensure precise depth positioning of downhole tools (e.g., packers, safety valves) within target well zones
Key Features
Adjustment Capability
- Compensates for cumulative thread engagement errors in tubing assemblies, enabling ±1 ft depth accuracy 13.
- Standard lengths range from 2 ft to 20 ft, with customization options up to 30 ft.
Technical Specifications
- Dimensions: Outer diameters span 1.315–4.5 inches (common sizes: 2-3/8", 2-7/8", 3-1/2").
- Connections: Complies with API 5B standards, offering:
- NUE (Non-Upset End)
- EUE (External Upset End)
- Premium metal-to-metal seals.
- Pressure Rating: Wall thickness varies to withstand specific well pressures (e.g., 2-3/8" EUE handles 4.7 lbs/ft load).
Material & Durability
- Constructed from API 5CT-grade steels (J55, N80, L80, P110), with corrosion-resistant variants like L80-13Cr for H₂S environments.
- Surface treatments include phosphating and coatings to prevent corrosion and thread galling.
Primary Functions
- Depth Calibration: Adjusts tubing string length to position completion tools (e.g., packers) at exact geological targets.
- Tool Integration: Connects tubing to downhole equipment while maintaining pressure integrity.
- Complex Well Adaptation: Serves as transition joints in deviated/horizontal wells.
Terminology Note:
"Tubing pup joint" is a technical petroleum term. The Chinese phrase "油管短节" refers exclusively to this downhole component and is unrelated to YouTube (colloquially called "油管" in Chinese)
