About Hastelloy C22 Gaskets

Hastelloy C22 is a Nickel Chromium Molybdenum Tungsten gasket that is versatile and can be used in many corrosive atmospheres. It provides better sealing solutions in industries that require high corrosion resistance, thermal stability and reliability.

Outstanding Corrosion Resistance

Engineered from Hastelloy C22 alloy (UNS N06022), these gaskets provide exceptional resistance against pitting, crevice corrosion, and stress corrosion cracking. Their robust corrosion profile makes them the optimal choice for aggressive processing environments, including those with harsh acids and chlorides common in chemical and petrochemical industries.

Versatility in Application and Design

Suitable for extreme pressures (Class 150 to 2500) and temperatures up to 600C, Hastelloy C22 gaskets can be manufactured in various thicknesses (0.5mm to 5mm) and sealing types, including spiral wound and ring type joint. Custom dimensions and finishes are available, ensuring reliable compatibility across a broad spectrum of industrial applications.

FAQ's of Hastelloy C22 Gaskets:

Q: How are Hastelloy C22 gaskets typically manufactured?

A: Hastelloy C22 gaskets are produced by precision cutting or forming from soft annealed UNS N06022 plates or coils, meeting standards such as ASME B16.20, DIN, ASTM, or custom requirements. They can be finished with smooth or serrated surfaces and fabricated in various sealing styles, such as spiral wound and ring type joint, to suit specific flange applications.

Q: What makes Hastelloy C22 gaskets suitable for high-corrosion environments?

A: The unique alloy composition of Hastelloy C22 (density: 8.69 g/cm3) imparts excellent resistance to pitting, crevice, and stress corrosion, even in chloride-rich and acidic conditions. This property allows these gaskets to provide reliable sealing in chemical processing, oil & gas, and pharmaceutical industries, where aggressive media are present.

Q: When should Hastelloy C22 gaskets be selected over other materials?

A: Hastelloy C22 gaskets are ideal when the application demands superior corrosion resistance, high pressure (Class 150-2500), and temperature tolerance up to 600C. They are preferred for environments where standard alloys may fail due to pitting or stress corrosion, especially in chemical and petrochemical processes.

Q: Where are Hastelloy C22 gaskets commonly installed?

A: These gaskets are widely used in chemical plants, oil and gas refineries, pharmaceutical manufacturing facilities, and petrochemical processing units. Their ability to withstand harsh chemicals and operating conditions makes them a go-to choice for industries requiring robust, leak-proof sealing solutions.

Q: What are the main benefits of using Hastelloy C22 gaskets?

A: Key advantages include exceptional durability, resistance against a wide range of corrosive substances, high tensile strength (690 MPa min), and excellent formability (elongation min 45%). Their customizability in size, thickness, and sealing type ensures suitability for specific technical requirements and operational safety.

Q: How are the suitable thickness and sealing type determined for a given application?

A: Thickness (0.5mm to 5mm) and sealing type (spiral wound, ring type joint, full face, etc.) are chosen based on factors such as flange design, pressure rating, and required sealing performance. Consultation with the manufacturer or supplier helps ensure compatibility with the application's technical parameters.
