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

Incoloy flanges are pipe flanges that are made from incoloy. Incoloy is a nickel-chromium-based superalloy, which is known for their excellent corrosion resistance and high-temperature strength. Incoloy flanges are important parts used in piping systems to connect pipes, valves, and equipment while providing easy access for maintenance and inspection. Incoloy flanges are made from several grade of incoloy alloys like Incoloy 800, Incoloy 800H, Incoloy 800HT, Incoloy 825, and Incoloy 925.Incoloy flanges weight and dimensions chart gives information about the composition.

Some of the advantages of using incoloy flanges are high strength, excellent corrosion resistance, strength and toughness, versatility and weldability. Incoloy 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. Incoloy 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 incoloy alloys come in different grades, each with its own set of properties and usefulness for specific applications. The selection of incoloy grade depends on the corrosive environment, temperature, pressure, and other factors involved in the application.

Incoloy Flanges Types

• 1. INCOLOY SLIP-ON FLANGES - The bore size of the incoloy 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. Incoloy slip-on flanges weight and dimensions chart gives detailed data about these flanges.
• 2. INCOLOY WELD NECK FLANGES - Incoloy 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. Incoloy weld neck flanges weight and dimensions chart gives detailed data about these flanges.
• 3. INCOLOY BLIND FLANGES - Most piping systems require regular audit and blind/blank flanges are most usual inspection point. This incoloy 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. Incoloy blind flanges weight and dimensions chart gives detailed data about these flanges.
• 4. INCOLOY THREADED FLANGES - You can build the incoloy 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. Incoloy threaded flanges weight and dimensions chart gives detailed data about these flanges.
• 5. INCOLOY LAP JOINT FLANGES - Lap joint flanges is 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. Incoloy 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. Incoloy lap joint flanges weight and dimensions chart gives detailed data about these flanges.
• 6. INCOLOY 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. Incoloy socket-weld flanges weight and dimensions chart gives detailed data about these flanges.

Incoloy Flanges Specifications

Incoloy flanges specifications are accessible in numerous grades. Incoloy 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. Incoloy 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.
