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

Monel flanges are flanged connectors or attachments made from Monel, a high-performance nickel-copper alloy known for its excellent corrosion resistance and durability. These flanges are used to connect pipes, valves, pumps, and other equipment in various industries where resistance to harsh environments is essential. Monel flanges are typically manufactured from Monel alloy grades, with Monel 400 (UNS N04400) and Monel K-500 (UNS N05500) being the most common choices. These alloys consist primarily of nickel and copper, with small amounts of other elements like iron, manganese, carbon, and silicon. Monel K-500 also includes aluminum and titanium for increased strength. Monel flanges weight and dimensions chart gives information about the composition.

They are also available in a range of sizes and ratings to meet the needs of different applications. Monel flanges weight and dimensions chart PDF explains all these sizes and ratings in mm and kg units. Monel flanges are joined to pipes using a welding process known as butt welding. In butt welding, the ends of the pipe and flange are aligned and welded together. This creates a strong and durable joint that is resistant to leakage and corrosion. Some of the advantages of using monel flanges are high strength, excellent corrosion resistance, good weldability, resistance to high temperatures and pressures, better fatigue resistance than other types of stainless steel, cost-effective solution for many applications. Monel 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.

Monel Flanges Types

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

Monel Flanges Specifications

Monel flanges specifications are accessible in numerous grades. Monel 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. Monel flanges are available in a wide range of sizes to accommodate different pipe diameters and system requirements. Refer to monel flanges weight and dimensions chart PDF given in mm and kg, for knowing more in details about flange sizes and specifications.
