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

Tantalum flanges are pipe flanges that are made from tantalum. Tantalum flanges are typically joined to pipes using a flanged joint, in which the flange is bolted to the pipe. This process creates a strong, leak-tight joint. Tantalum flanges are important parts used in piping systems to connect pipes, valves, and equipment while providing easy access for maintenance and inspection. Tantalum flanges weight and dimensions chart gives information about the composition.

Some of the advantages of using tantalum flanges are high strength, excellent corrosion resistance, high temperature resistance, outstanding purity, high melting point, and good ductility. Tantalum flanges are available in different pressure ratings to accommodate various pressure and temperature conditions. Tantalum flanges are available in a range of sizes and dimensions to fit different piping configurations and flow requirements. All these sizes are curated in detail in tantalum weight and dimensions chart PDF in mm and kg. Tantalum 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.

Tantalum Flanges Types

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

Tantalum Flanges Specifications

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