Supplier's note

  1. Technical Breakthroughs:

    • API 5CT Compliance: Ensures compatibility with oil country tubular goods standards for drilling safety.
    • 1% Tolerance Precision: Enables seamless connections in high-pressure hydraulic systems.
    • Custom Thread Configurations: Reduces installation time by 20% compared to traditional field-welded joints.

  2. Version Selection Guidance:

    • Base Model (J55): Ideal for shallow drilling or low-pressure applications where cost efficiency is prioritized.
    • Advanced Model (K55): Suitable for moderate-depth drilling or chemical pipelines requiring enhanced durability.
    • Pro Model (N80): Designed for ultra-deep drilling or high-pressure gas transport, offering triple the corrosion resistance of standard steel pipes.

With the Pro Model’s 63,700 psi yield strength, operators can safely handle abrasive fluids in offshore drilling. Pair its thick walls with LTC threading for a 30% faster assembly process, reducing downtime in critical operations.

Note: Performance metrics are relative to the Base Model’s specifications.
