Haihao Group Delivers ASTM B564 UNS N06625 Flanges to Singapore for High-Corrosion Industrial Service

Haihao Group has successfully completed the production and shipment of a batch of ASTM B564 UNS N06625 flanges for a valued customer in Singapore. The order includes both welding neck flanges (WN Flanges) and socket weld flanges (SW Flanges) manufactured in strict accordance with ASME B16.5.

Designed for demanding industrial environments, these nickel alloy flanges offer outstanding resistance to chloride corrosion, oxidation, and high-temperature service, making them suitable for offshore platforms, petrochemical plants, chemical processing facilities, LNG projects, and other aggressive applications.

Throughout the manufacturing process, Haihao Group followed rigorous quality control procedures to ensure every ASTM B564 UNS N06625 flange fully complied with the customer’s specifications before shipment.

Why ASTM B564 UNS N06625 Flanges Are Preferred

The primary material used for this project is ASTM B564 UNS N06625, a nickel-chromium-molybdenum alloy widely recognized for its excellent performance in highly corrosive and elevated-temperature environments.

Compared with conventional stainless steel flanges, ASTM B564 UNS N06625 flanges provide several advantages:

• Exceptional resistance to pitting and crevice corrosion
• Outstanding oxidation resistance at elevated temperatures
• High mechanical strength over a wide temperature range
• Excellent fatigue and thermal cycling performance
• Superior weldability without significant post-weld cracking
• Long service life in offshore and chemical processing systems

These characteristics make ASTM B564 UNS N06625 flanges an ideal choice for critical piping systems where long-term reliability is essential.

Manufacturing in Compliance with ASME B16.5

All flanges in this shipment were manufactured according to ASME B16.5, ensuring dimensional accuracy, pressure integrity, and interchangeability with international piping systems.

Haihao Group’s manufacturing process includes:

• Certified raw material inspection
• CNC precision machining
• Dimensional inspection
• Raised face machining
• Surface protection before shipment
• Final visual and documentation review

Every ASTM B564 UNS N06625 flange underwent comprehensive quality verification before packing.

Secure Packaging for International Transportation

To prevent damage during overseas transportation to Singapore, Haihao Group adopted enhanced export packaging.

Packaging Item	Implementation
Flange Protection	Plastic protective caps installed on all sealing faces
Export Packing	Strong fumigation-free wooden cases
Surface Protection	Carefully protected against scratches and impact
Shipment Identification	Clear product marking for easy installation

Proper packaging helps maintain the integrity of every ASTM B564 UNS N06625 flange throughout international logistics.
