Slip-on Flanges SORF Nickel Alloy Flanges for High Pressure Enveronment Pipe Flanges

Nickel alloy threaded flanges are a type of flange designed to be joined to a piping system by threading. They are commonly made from various nickel alloys to enhance their ability to withstand a range of corrosive environments, high temperatures, and pressures. Here are some details about nickel alloy threaded flanges:

Materials of Construction
Nickel alloy threaded flanges are made from nickel-based alloys known for their excellent corrosion resistance and strength at high temperatures.

The most common nickel alloys for flanges include:

• Alloy 200/201 (UNS N02200/N02201): Pure nickel with good mechanical properties and excellent resistance to many corrosives, particularly halides.
• Alloy 400 (UNS N04400): Known as Monel 400, has excellent corrosion resistance in a range of acidic and alkaline environments and is especially suitable for reducing conditions.
• Alloy 600 (UNS N06600): Known as Inconel 600, resistant to a wide range of corrosive substances and high temperatures.
• Alloy 625 (UNS N06625): Known as Inconel 625, has high strength and toughness from cryogenic temperatures to 1800°F (982°C), and is oxidation and corrosion-resistant.
• Alloy 825 (UNS N08825): Known as Incoloy 825, resistant to many corrosive environments and has good mechanical properties at both room and elevated temperatures.
• Alloy C276 (UNS N10276): Known as Hastelloy C276, has excellent resistance to a wide variety of chemical process environments.

Features

• Threaded Connection: They have threads inside the bore which match the external threads on the pipe. This allows for a connection without welding. This is particularly useful in explosive or hazardous environments where welding is not advisable.
• Ease of Assembly: They can be assembled without welding, making them convenient for use in maintenance or assembly of systems where welding is not possible or difficult.
• Pressure Classes: Threaded flanges typically come in various pressure classes, depending on the specific nickel alloy and the standards they conform to (e.g., ANSI/ASME B16.5).

Specifications

• Standards: They are manufactured in accordance with standards like ANSI/ASME B16.5, B16.36, MSS SP-44, API 6A, and others depending on industry and application requirements.
• Sizes: Typically available from 1/2 inch to 24 inches in diameter, though larger sizes can be custom made.
• Pressure Ratings: Pressure ratings for nickel alloy threaded flanges can range from 150 to 2500 pounds or higher, depending on size and material grade.

Applications

• Nickel alloy threaded flanges are used in applications that require flanges capable of handling harsh environments such as:
• Chemical processing
• Petrochemical industry
• Oil and gas exploration and processing
• Power generation
• Marine environments
• Heat exchangers and condensers
