فلنج ASME B16.5 B564 UNS N04400

استاندارد ASME B16.5 طرح های مختلف فلنج را پوشش می دهد، از جمله:

  • فلنج گردن جوش: برای سیستم های فشار بالا که از طریق جوش متصل می شوند ترجیح داده می شود.
  • فلنج لغزنده: نصب آسان، مناسب برای کاربردهای کم فشار.
  • فلنج کور: برای آب بندی انتهای لوله ها استفاده می شود.
  • فلنج رزوه ای: از طریق رزوه متصل می شود و نیازی به جوشکاری ندارد.
  • فلنج مفصل دام: جفت شده با انتهای خرد برای جداسازی آسان.

خواص مکانیکی:

تراکم8.80-8.84 g/cm³Slightly higher than stainless steel
استحکام کششی450-827 MPa (as processed)Can reach ~1241 MPa after cold working
قدرت تسلیم170-758 MPaImproves significantly with cold work
ازدیاد طول30-50%Excellent ductility and toughness
مقاومت در برابر دماUp to 600°C (continuous in air)Corrosion rate <0.026 mm/a in steam

مقاومت در برابر خوردگی:

N04400 performs exceptionally well in the following environments:

  • Acidic Media: Resistant to sulfuric acid (≤85%), hydrofluoric acid, and hydrochloric acid (≤20%), making it one of the few materials capable of withstanding hydrofluoric acid.
  • Alkaline Environments: Exhibits excellent resistance to hot concentrated alkalis (e.g., sodium hydroxide).
  • Seawater and Brine: Resistant to chloride stress corrosion cracking, with a corrosion rate below 0.025 mm/a, commonly used in marine engineering equipment.
  • High-Temperature Corrosion: Stable in anhydrous ammonia environments up to 585°C, suitable for nuclear industry equipment.

ملاحظات انتخاب و استفاده

معیارهای انتخاب:

  • Match pressure class (e.g., Class 600+) with medium corrosivity, temperature, and pressure;
  • Prefer RTJ sealing faces for high-pressure systems.

Installation & Maintenance:

  • Use bolts of the same material (e.g., Monel 400) to avoid galvanic corrosion;
  • Regularly inspect sealing faces; graphite or PTFE gaskets are recommended.

برنامه های کاربردی معمولی

The versatility of N04400 makes it widely applicable in several key industries:

  • Marine Engineering: Seawater desalination equipment, pump shafts, propellers, and offshore platform structures.
  • Chemical and Petrochemical: Reactors, heat exchangers, storage tanks, and pipelines for acid/alkali transport.
  • Nuclear and Aerospace: Nuclear reactor cooling systems, aircraft engine components, and fuel systems.
  • Energy and Shipbuilding: Oil drilling platforms, ship valves, and seawater cooling systems.
  • Machining and Welding
  • Machining Characteristics: Can be formed via cold/hot working; cold working significantly increases strength but requires attention to machining shrinkage allowances to maintain precision.
  • Welding Processes: Compatible with TIG, MIG, and manual arc welding. Recommended filler materials include EniCu-7 or ERNiCu-7, with welded joint performance closely matching the base metal.

International Grade Equivalents

  • United States: UNS N04400 (ASTM B164)
  • Germany: 2.4360 (DIN)
  • China: NS311 (GB)
  • Japan: NW4400 (JIS).

More Information about ASME B16.5 B564 UNS N04400 Flange

Design and Manufacturing

  • Forming Process: Forging (as per ASTM B564), ensuring material density and mechanical properties;
  • Pressure Ratings: Commonly Class 150 to Class 900, suitable for medium-to-high-pressure systems;
  • Sealing Face Machining: High-precision turning ensures sealing reliability (e.g., RF face roughness Ra ≤3.2μm).

Performance Advantages

  • Corrosion Resistance Lifespan: 5-10 times longer than standard stainless steel flanges in chloride or acidic environments;
  • High-Temperature Stability: Strength retention >80% at 400°C, suitable for heat exchange systems;
  • Cost-Effectiveness: Higher initial cost but lower maintenance frequency, offering better long-term value than carbon steel flanges.

Pressure–Temperature Ratings for B564 UNS N04400

سوالات متداول

  • Dimensional Compatibility: ASME B16.5 flanges do not directly match EN standard flanges and may require adapter rings or custom gaskets.
  • Material Equivalence: UNS N04400 corresponds to the European standard 2.4360 (DIN), with nearly identical chemical composition and properties.
  • Applicability: Performs well in wet hydrogen environments ≤260°C. For higher temperatures, Inconel 625 (UNS N06625) is recommended.
  • Reference Standard: Follow ASME B16.5 based on design pressure/temperature (e.g., Class 300 ≈ 50 bar @ 100°C).
  • Corrosion Allowance: Increase by 1-2 pressure classes (e.g., from Class 150 to Class 300) for corrosive media.
  • Mandatory: Use Monel 400 or Inconel 600 bolts to prevent galvanic corrosion with carbon steel.

منابع بیشتر:

UNS N04400 flanges are ideal for harsh environments (acidic, seawater, high-temperature) but require strict compliance with ASME/ASTM standards. Selection should consider media properties, pressure-temperature profiles, and lifecycle costs. For budget-limited projects, 316L + anti-corrosion coatings may be used in non-critical sections.
