Order Details

High-Performance ASTM B564 UNS N06625 Blind Flange for Corrosive Service

The ASTM B564 UNS N06625 Blind Flange supplied for this project is manufactured from forged Alloy 625, a nickel-chromium-molybdenum alloy widely recognized for its outstanding resistance to corrosion and oxidation.

Compared with conventional stainless steel flanges, ASTM B564 UNS N06625 Blind Flange products maintain excellent mechanical strength under elevated temperatures while resisting pitting, crevice corrosion, chloride attack, and stress corrosion cracking. These characteristics make them an ideal choice for offshore platforms, seawater systems, sour gas facilities, and aggressive chemical processing plants.

For Singapore’s marine climate and industrial applications, selecting an ASTM B564 UNS N06625 Blind Flange helps improve pipeline reliability and reduce maintenance costs over the equipment lifecycle.

Manufactured to ASME B16.5 Requirements

Every flange in this shipment was produced according to ASME B16.5 dimensional and pressure specifications. Haihao Group performs comprehensive inspections throughout production to ensure each component fully complies with customer requirements.

Quality control includes:

• Raw material verification
• Dimensional inspection
• Machining accuracy inspection
• Raised Face (RF) sealing surface examination
• Surface finish inspection
• Marking verification
• Final visual inspection before packing

These inspection procedures ensure every ASTM B564 UNS N06625 Blind Flange provides reliable sealing performance and installation compatibility in critical piping systems.

Why Choose UNS N06625 Blind Flanges?

UNS N06625 (Alloy 625) offers numerous advantages over conventional carbon steel and standard stainless steel materials.

Key benefits include:

• Exceptional resistance to seawater corrosion
• Superior resistance to chloride-induced pitting
• Excellent performance in oxidizing and reducing environments
• High tensile and fatigue strength
• Outstanding weldability
• Excellent high-temperature oxidation resistance
• Long service life with minimal maintenance

These properties make ASTM B564 UNS N06625 Blind Flange products particularly suitable for offshore engineering, LNG facilities, desalination plants, refineries, and chemical processing systems.
