A pup joint is a pipe of non-standard length used to adjust the length of tubular strings to its exact requirement. API casing and tubing pup joints are manufactured according to API Spec 5CT using prime API monogrammed, seamless oil country tubing.

Tubing pup joints are used to connect or adjust the length of the tubing string in oil and gas wells. Typically shorter than standard tubing (0.5m-3m), they feature high strength, corrosion resistance, and excellent sealing properties.

• Adjust tubing string length to meet well depth requirements
• Replace damaged oil pipe sections
• Serve as adapter joints and sealing sections

• Pipe body standard: API Spec-5CT compliant for material, mechanical properties, and dimensional tolerances
• Thread standard: API Spec-5CT compliant for thread accuracy, strength, and sealing performance

The most common type, suitable for general oil extraction and transportation scenarios with conventional connection requirements.

Features external threads (PIN) on both ends for connecting two oil pipes or fittings with internal threads (BOX).

Enhanced wall thickness through specialized processes for improved strength and pressure resistance in high-pressure applications.

• 1-year quality guarantee with free maintenance for any manufacturing defects
• Lifetime technical support and fittings availability
• 24/7 responsive after-sales service with immediate technical assistance
