Why ASME B16.47 Exists:
ASME B16.47 was developed to meet the demands for flanges in large pipeline systems. As the industry’s need for large-diameter and high-pressure pipeline systems has increased, standardized flange sizes and design requirements needed to accommodate larger dimensions and different operational conditions. ASME B16.47 provides a standard specifically designed to address these needs, ensuring performance and reliability of flanges in larger pipelines.
ASME B16.5:
Applicable to flanges ranging from NPS 1/2 to 24 inches.
Pressure ratings include 150, 300, 600, 900, 1500, and 2500.
ASME B16.47:
Applicable to flanges ranging from NPS 26 to 60 inches.
Designed to meet the needs for larger size flanges.
Pressure ratings include 75, 150, 300, 400, 600, 900, and 1500.
Wat is het verschil tussen ASME B16.47 Serie A en B?
This table outlines the key differences between Series A and Series B flanges to help you choose the appropriate flange type.
| Functie | Series A | Series B |
| Thickness, Weight, and Strength | Thicker, heavier, and stronger, capable of handling more external loading. Generally more expensive. | Thinner, lighter, suitable for lighter loads. |
| Bevestigingsmiddelen | Requires fewer large fasteners, with a larger bolt circle diameter. | Requires more but smaller fasteners, with a smaller bolt circle diameter. |
| Flensvlaktypen | Defines raised face weld neck and blind flanges, and includes ring-type joint (RTJ) flanges from Class 300 to Class 900. | Also defines raised face weld neck and blind flanges but does not include RTJ flanges. |
| Sollicitatie | Suitable for new pipeline projects or equipment due to higher load capacity and strength. | More commonly used for refurbishment or replacement jobs. |
| Other Names | MSS SP44 | API 605 |
