ANSI B16.5 Nickel Alloy Flanges Weight, Dimensions Chart in mm, kg, PDF online

Nickel alloy flanges are pipe flanges that are made from various alloys of nickel. These alloys are known for their excellent resistance to corrosion, high-temperature performance, and superior mechanical properties. This gives nickel alloy a blend of the desirable properties of both nickel and other elements which form an alloy. Nickel alloy flanges are necessary parts used in piping systems to connect pipes, valves, and equipment while providing easy access for maintenance and inspection. There are various nickel alloys available, each with its unique properties. Some common nickel alloys used in flange manufacturing include Inconel, Monel, Hastelloy, and Nickel 200/201. The choice of alloy depends on the specific requirements of the application. Nickel alloy flanges weight and dimensions chart PDF gives more information about the various composition.

Some of the advantages of using nickel alloy flanges are high strength, excellent corrosion resistance, strength and toughness, and weldability. Nickel alloy flanges are used in a large variety of applications, including oil and gas, chemical processing, marine, power generation, pulp and paper, food and beverage and pharmaceuticals. These flanges come in all sorts of sizes and configurations, including raised face flanges, flat face flanges, and ring type joint flanges. These sizes and configurations are discussed further in weight and dimensions chart PDF in mm and kg units. This chart is available below. It is important to note that nickel alloys are available in different types, each with its own set of properties and usefulness for specific applications. The selection of nickel alloy grade depends on the corrosive environment, temperature, pressure, and other factors involved in the application.

Nickel Alloy Flanges Types

• 1. NICKEL ALLOY SLIP-ON FLANGES - The bore size of the nickel alloy slip-on flange as a standard is slightly larger than the outside diameter of the connecting pipe, as the pipe has to slide inside the flange then needs to be connected by the execution of the fillet weld around the border. Nickel alloy slip-on flanges weight and dimensions chart gives detailed data about these flanges.
• 2. NICKEL ALLOY WELD NECK FLANGES - Nickel alloy weld neck flanges are helpful in high/low-temperature applications and high-pressures that require an unlimited fluid flow conveyed by the piping system. These butt-weld end connection flanges are most usual in industrial applications to ensure a high strength connection between assemblies. Nickel alloy weld neck flanges weight and dimensions chart gives detailed data about these flanges.
• 3. NICKEL ALLOY BLIND FLANGES - Most piping systems require regular audit and blind/blank flanges are most usual inspection point. This nickel alloy blind flanges, when selected according to the suitable pressure class, can easily handle the tension caused by the liquid’s operating pressure and pressure flowing through the pipe. They are useful to ‘blank off’ valves, pipelines, etc. in almost all applications. Nickel alloy blind flanges weight and dimensions chart gives detailed data about these flanges.
• 4. NICKEL ALLOY THREADED FLANGES - You can build the nickel alloy threaded flanges without welding, and hence it is easy to remove. You do not have to use it for usages where bending stresses involve high pressure or temperatures. A seal weld is useful in combination with times. Nickel alloy threaded flanges weight and dimensions chart gives detailed data about these flanges.
• 5. NICKEL ALLOY LAP JOINT FLANGES - Nickel alloy lap joint flanges are a type of slip-on flange but made for connecting to a stub end for rotation. Lap joints are helpful to keep carbon/low alloy steel pipes with additional mechanical properties. Nickel alloy lap joint flanges are similar to slip-on flanges but are characterized by the radius-rounded interior edge of the flange face and generally come with a taller hub. Nickel alloy lap joint flanges weight and dimensions chart gives detailed data about these flanges.
• 6. NICKEL ALLOY SOCKET-WELD FLANGES - Smaller diameter socket weld and counter bore flanges handle the applications with high pressures like steam lines but with restricted spacing. You must ensure toughness possess internal welds—the bore of the pipe and flange match provides a good flow connection. Nickel alloy socket-weld flanges weight and dimensions chart gives detailed data about these flanges.

Nickel Alloy Flanges Specifications

Nickel alloy flanges specifications are accessible in numerous grades. Nickel alloy flanges are manufactured in accordance with a variety of standards, including ASTM A182, ASTM A815, ANSI/ASME B16.5, DIN 55014 and BS EN 1092-1, with pressure ratings from Class 150, 300, 600, 2500 and beyond. Nickel alloy flanges are available in a wide range of sizes to accommodate different pipe diameters and system requirements. Refer to weight and dimensions chart PDF given in mm and kg, for knowing more in details about flange sizes and specifications.
