Why Choose ASTM B564 UNS N06625 Flanges?
ASTM B564 UNS N06625 flange products are manufactured from a nickel-chromium-molybdenum alloy that performs exceptionally well in severe service environments where stainless steel may not provide sufficient corrosion resistance.
Key advantages include:
- Excellent resistance to chloride-induced pitting and crevice corrosion
- Outstanding oxidation resistance at elevated temperatures
- High tensile and fatigue strength
- Superior resistance to stress corrosion cracking
- Excellent weldability without sacrificing mechanical properties
- Long-term reliability in offshore and chemical processing applications
Because of these properties, ASTM B564 UNS N06625 flanges are widely specified for offshore platforms, LNG facilities, petrochemical plants, desalination systems, marine engineering, and power generation projects.
Manufactured to ASME B16.5 Requirements
Every flange supplied for this Singapore project was manufactured in accordance with ASME B16.5, ensuring dimensional accuracy, sealing performance, and full compatibility with international piping systems.
Haihao Group’s manufacturing process includes:
| Manufacturing Stage | Quality Control |
| Raw Material Inspection | Certified ASTM B564 UNS N06625 material verification |
| Precision Machining | CNC machining to ASME B16.5 dimensions |
| Dimensional Inspection | 100% inspection before final acceptance |
| Raised Face Machining | Accurate RF sealing surface finish |
| Final Inspection | Visual examination, marking, and documentation review |
Every ASTM B564 UNS N06625 flange was inspected before shipment to ensure compliance with customer specifications.
Export Packaging Designed for International Delivery
To ensure the flanges arrived in excellent condition, Haihao Group applied export-grade packaging procedures.
| Packaging Item | Details |
| Sealing Face Protection | Plastic protective caps installed on all RF faces |
| Surface Protection | Carefully protected against scratches and handling damage |
