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

Inconel flanges are a type of pipe fitting used to connect piping or equipment sections requiring an opening to be sealed or closed. They are made from inconel, a family of nickel-chromium-based alloys known for their high strength, excellent corrosion resistance & ability to withstand high temperatures and pressures. Inconel Flanges weight dimensions are in kg.

An inconel flange casting is typically a cast ring designed to connect the parts of a pipe or other machinery which requires a connecting joint. Most cast options are outdated and inconel flanges provided to modern specifications are made from plate or forged carbon steel or stainless steel. Before you buy inconel flanges, it is important to note that these flanges come in different measurements, diameters, sizes, types, and materials. Several types of inconel flanges are available for different types of uses. Therefore, you have to choose your product on a per-project basis. When we talk about the materials to use in your applications, a range of factors come into play. Therefore, some important aspects that are required to be considered while buying inconel flanges. For detailed measurements of inconel flanges, refer to dimensions chart below.

Inconel Flanges Types

• 1. INCONEL SLIP-ON FLANGES - The bore size of the inconel 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. For knowing more about inconel slip-on flanges dimensions, inconel flanges dimensions is presented below.
• 2. INCONEL WELD NECK FLANGES - Inconel 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. Refer to inconel flanges weight and dimensions chart PDF for detailed dimensions.
• 3. INCONEL BLIND FLANGES - Most piping systems require regular audit and blind/blank flanges are most usual inspection point. This inconel 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. Inconel flanges weight and dimensions chart gives very accurate measurements.
• 4. INCONEL THREADED FLANGES - You can build the inconel 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. Refer to Dimensions Chart for detailed dimensions.
• 5. INCONEL LAP JOINT FLANGES - Inconel 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. Inconel 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. Inconel flanges weight chart are in mm and kg.
• 6. INCONEL 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. Refer to dimensions chart for detailed weight and dimensions of inconel socket-weld flanges.

Inconel Flanges Specifications

Inconel Flanges specifications are accessible in numerous grades. The client’s selection of products needs to depend on the budget and project you need. However, top-quality products need to be costly and need to be sturdy. Usual material standards and grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500. Both Inconel 316/L Flanges and Inconel 304/L flanges are corrosion resistant alloys with a high, 95% alloy composition. Inconel 316 and Inconel 304 belong to the chromium-nickel category and are grades that handle standard corrosion. It needs to be tough, resists most basic chemicals, and hold more excellent resistance to numerous types of decay. Refer to weight and dimensions Chart for detailed specifications.
