TISCO Steel Group: Your Trusted Partner for Premium 2507 Super Duplex Pipes

TISCO Steel Group (Jiangsu) Co., Limited is a distinguished supplier and stockist of high-performance stainless steel materials. We hold strong partnerships with China’s top mills, including TISCO, Tsingshan, BAOSTEEL, and ANSTEEL, ensuring our clients receive mill-direct, certified-quality products that meet the most stringent international standards.

Our 2507 Super Duplex Stainless Steel Pipes represent the pinnacle of corrosion resistance and mechanical strength. This grade combines a dual-phase microstructure of austenite and ferrite, delivering yield strength that is approximately twice that of standard 316L or 317L austenitic steels. This makes it an ideal, cost-effective solution for applications where weight savings and superior performance are critical.

Key Advantages of 2507 Pipes:

  • Exceptional Corrosion Resistance: Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich environments, outperforming 316L and 904L.

  • High Strength: High mechanical strength allows for reduced wall thickness, leading to significant savings in material and weight.

  • Versatility: Suitable for a wide range of demanding applications.

Primary Applications:
Oil & Gas (downhole tubing, flow lines), Chemical & Petrochemical Processing, Offshore and Marine Systems, Desalination Plants, and Pollution Control Equipment.

FAQ

  1. What is the difference between Duplex 2205 and Super Duplex 2507?
    Super Duplex 2507 has higher chromium, molybdenum, and nitrogen content, providing superior strength and corrosion resistance, especially in aggressive chloride environments, compared to Duplex 2205.

  2. Do your 2507 pipes come with proper certification?
    Yes, every pipe is supplied with a complete Mill Test Certificate (MTC) conforming to ASTM A790/A790M, which verifies chemical composition and mechanical properties.

  3. Can you provide pipes matching ASTM A790 standard?
    Absolutely. Our 2507 pipes are produced to meet and exceed ASTM A790/A790M, the standard specification for seamless and welded ferritic/austenitic duplex stainless steel pipe.

  4. What is the PREN value of 2507 stainless steel?
    The Pitting Resistance Equivalent Number (PREN) for 2507 is typically >40, guaranteeing excellent resistance to pitting corrosion.

  5. What are the available forms (seamless or welded) and sizes?
    We supply both ASTM A790 seamless and ASTM A928 welded pipes. Standard outer diameters range from 1/2″ to 24″, with custom sizes available upon request.

  6. What is the minimum order quantity (MOQ)?
    Our standard MOQ is 1 ton, but we can accommodate smaller orders for sample testing and evaluation.

  7. What is the lead time for orders?
    For standard sizes and grades, lead time is typically 15-20 days. We will provide a precise timeline upon order confirmation.

  8. How do 2507 pipes perform in sulfuric acid environments?
    2507 offers good resistance to diluted sulfuric acid. However, for specific concentration and temperature conditions, please consult our technical team for detailed advice.

  9. What is the maximum operating temperature for 2507 pipe?
    It is generally recommended for use up to 300°C (572°F) to avoid embrittlement issues. For continuous high-temperature service, other grades may be more suitable.

  10. Do you offer processing services like cutting or beveling?
    Yes, we provide value-added services including precision cutting, end bevelling, and deburring to meet your project requirements ready for installation.

Additional Services

We provide value-added services including rough machining, heat treatment, cutting, machining, rolling, welding, and surface treatment to ensure your finished product is delivered ready for finishing. All forgings are rough machined according to your specifications and include Mill Test Reports (MTR), Mechanical and Physical Property Reports, as well as Ultrasonic, X-Ray, and Non-Destructive Testing (NDT) reports (as ordered or specified).
