What types of Alloy 20 flanges are available?

Alloy 20 flanges are available in various types to meet different piping requirements. Common types include weld neck flanges, slip-on flanges, blind flanges, socket weld flanges, threaded flanges, and lap joint flanges. These flanges come in different sizes, pressure ratings, and facing options, allowing for versatile installation and assembly of piping systems.

Can Alloy 20 flanges be used in cryogenic applications?

Yes, Alloy 20 flanges can be used in cryogenic applications. They maintain their mechanical properties and corrosion resistance at extremely low temperatures, making them suitable for applications in industries such as liquefied natural gas (LNG) processing, cryogenic storage, and refrigeration.

What is the maximum temperature limit for Alloy 20 flanges?

Alloy 20 flanges have a maximum recommended temperature limit of around 925°C (1700°F). Operating above this temperature may lead to a reduction in mechanical properties, including strength and toughness. It is crucial to consider the specific temperature requirements and consult the manufacturer’s specifications for the appropriate selection of Alloy 20 flanges.
