Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Oil & Gas Drilling Support: Designed as OCTG (Oil Country Tubular Goods) casing and tubing for high-pressure applications in petroleum extraction, ensuring structural integrity in wellbores.
  • Industrial Structural Use: Thick-walled carbon steel construction (ASTM/GB standards) enables robust support in infrastructure projects requiring corrosion resistance and pressure tolerance.

Key features

  • 1. Material Technology: ASTM & API 5CT Compliant Carbon Steel

    • With ASTM and API 5CT certified carbon steel construction, ensure structural integrity and corrosion resistance in petroleum drilling environments. The non-alloy material meets strict industry standards for harsh conditions, outperforming non-certified alternatives*.

  • 2. Interactive Design: BTC Coupling for Secure Assembly

    • The Bevelled Thread and Crest (BTC) coupling design enables rapid, leak-proof connections, simplifying on-site installation compared to traditional threaded systems. Reduces assembly time by ~30% in field deployments*.

  • 3. Performance Parameters: Thick-Wall Construction & Tight Tolerances

    • With thick walls and N80/L80 grade steel, withstand extreme pressures (up to 15,000 psi) in deep drilling operations. 1% tolerance ensures precise fitment, exceeding standard pipe accuracy by 50%*.

  • 4. Scenario Solutions: Customizable for Deep Drilling Projects

    • Engineered for oil/gas well casing and tubing applications, these pipes adapt to diverse geological conditions. Thick walls and round section shapes optimize performance in high-pressure, corrosive environments versus general structure pipes*.

  • 5. Certification Standards: CE & API 5CT Compliance

    • Certified to CE, ASTM, and API 5CT standards, ensuring safety and quality for commercial oilfield operations. Meets global regulatory requirements, unlike uncertified alternatives*.

Supplier's note

  1. Technical Breakthroughs:

    • API 5CT Compliance: Ensures safety and performance in oil/gas drilling.
    • N80/L80 Grades: Triple the pressure tolerance of standard pipes, ideal for deep-sea drilling.
    • BTC Couplings: 20% tighter seals than traditional threads, reducing leakage risks.

  2. Version Selection Guide:

    • Base Model: Suitable for standard construction projects requiring basic pressure resistance (e.g., water pipelines).
    • Advanced Model: Optimal for harsh environments (e.g., offshore drilling) with enhanced corrosion and pressure handling.
    • Pro Model: Designed for extreme applications like ultra-deep wells, where 30% thicker walls and epoxy coatings guarantee longevity.

Example Use Case: The Pro version’s 11.5mm wall thickness and epoxy coating enable safe handling of corrosive chemicals in refineries, paired with BTC couplings to ensure zero leakage during high-pressure operations.
