ASME B 16.47 Series B Weld Neck Flange | Emirerri Steel

The ASME B 16.47 Series B Weld Neck Flange is a critical component in high-pressure and high-temperature piping systems. Its product description typically includes several key features and specifications to ensure compatibility and performance in various industrial applications. Here’s a general product description for an ASME B16.47 Series B Weld Neck Flange:

1. Material: The flange is constructed from high-quality materials such as carbon steel, stainless steel, or alloy steel, selected based on the requirements of the application and the operating conditions.
2. Dimensions: The flange conforms to the dimensional requirements specified in ASME B16.47 Series B standard. It features a larger diameter and thickness compared to Series A flanges to withstand higher pressures.
3. Design: The weld neck design features a long tapered hub, or neck, with a smooth transition to the pipe bore. This design minimizes stress concentration and ensures uniform distribution of stress during operation, reducing the risk of failure.
4. Pressure Rating: The flange is rated for specific pressure classes defined in the ASME B16.47 standard. Series B flanges typically have higher pressure ratings compared to Series A flanges, making them suitable for demanding applications where elevated pressures are encountered.
5. Raised Face: The flange typically features a raised face with a smooth surface finish to provide a sealing surface when bolted to a mating flange or fitting. This ensures a reliable and leak-free joint when properly installed.
6. Manufacturing Standards: The flange is manufactured in accordance with ASME B16.47 Series B standards, ensuring compliance with industry specifications and regulations.
7. Corrosion Resistance: Depending on the material selected, the flange may offer excellent corrosion resistance properties, making it suitable for use in corrosive environments.
8. Sizes: Available in a range of sizes to accommodate various pipe diameters and system requirements.
9. Applications: Commonly used in industries such as oil and gas, petrochemical, power generation, and process piping systems where high-pressure and high-temperature conditions are encountered.
10. Certifications: The flange may be accompanied by relevant certifications and documentation, such as material test reports (MTRs) and pressure test certificates, to ensure quality and traceability.

Overall, the ASME B16.47 Series B Weld Neck Flange is designed to meet the demanding requirements of industrial piping systems, providing reliable performance and long-term durability in challenging operating environments.
