ASTM B 564 UNS N08020 / Alloy 20 WNRF Flange Nickel Alloy Weld Neck Flange

ASTM B564 UNS N08020 / Alloy 20 Weld Neck Flange is a premium, high-integrity piping component designed for the most demanding corrosive and high-pressure services. Its strength, durability, and exceptional chemical resistance make it a critical solution in industries where failure is not an option.

When to Specify Alloy 20? Specify Alloy 20 when you need:

Proven resistance to sulfuric acid and phosphoric acid.
Good general corrosion resistance where 316L is failing.
Resistance to Chloride Stress Corrosion Cracking.
A cost-effective solution that avoids the high cost of more exotic alloys like Hastelloy.

Key Features & Advantages

Superior Strength in Harsh Environments: The combination of the robust weld neck design and the high-strength Alloy 20 forging makes it capable of withstanding high pressures and temperatures in corrosive service.
Excellent Weldability: The "weld neck" is designed to be butt-welded directly to the pipe, creating a strong, reliable joint. Alloy 20 itself is readily weldable using compatible filler metals (e.g., ER320LR, ENi-6620).
Long Service Life: Its exceptional resistance to a wide range of corrosives minimizes maintenance, downtime, and replacement costs.
Smooth Flow Path: The tapered hub allows for a smooth transition from the pipe to the flange, reducing turbulence and pressure drop

Application

This flange is used in industries where standard stainless steels (304/316) fail due to corrosion.

Chemical Processing Industry (CPI): Reactors, tanks, and piping handling sulfuric acid, phosphoric acid, and other aggressive chemicals.
Pharmaceutical Industry: For processes involving high-purity and corrosive intermediates.
Food and Beverage Processing: Especially in applications with acidic ingredients and chlorinated cleaning agents.
Oil & Gas (Upstream & Midstream): Handling of sour gases (H₂S) and other corrosive wellstream components.
Pulp & Paper Industry: Digesters and bleaching equipment.
Plastic Manufacturing: Plants producing synthetic fibers and polymers.
