Frequently Asked Questions (FAQs) about ANSI B16.47 Series A Flanges

1. What is ANSI B16.47 Series A?: ANSI B16.47 Series A is a standard that covers large diameter flanges (NPS 26 to NPS 60), specifically designed for high-pressure piping systems. These flanges are generally thicker and have larger bolt circles than Series B.
2. What flange types are available in ANSI B16.47 Series A?: Only two flange types are covered: Weld Neck Flanges and Blind Flanges.
3. What pressure classes are available in ANSI B16.47 Series A?: Series A flanges are available in Class 75, 150, 300, 400, 600, and 900 pressure ratings.
4. How is Series A different from Series B?: Series A flanges have a larger bolt circle diameter and fewer bolt holes than Series B, offering better load distribution for high-pressure applications. Series B is more compact and often used for lower pressure.
5. What materials are ANSI B16.47 Series A flanges manufactured in?: These flanges are available in Carbon Steel, Stainless Steel, Duplex Steel, Super Duplex, Inconel, Monel, Hastelloy, Copper Nickel, Alloy 20, and other exotic alloys.
6. Are gasket types standard for ANSI B16.47 Series A?: Yes, standard gaskets like spiral wound gaskets with metallic or non-metallic fillers are used depending on the pressure class and application.
7. Can these flanges be customized?: Yes, custom dimensions, facing types (RF, FF, RTJ), and coatings can be provided based on specific project requirements.
8. Are ANSI B16.47 Series A flanges suitable for offshore applications?: Absolutely. Their robust construction and high-pressure handling capability make them ideal for offshore oil & gas and petrochemical industries.
9. Do you offer third-party inspection and material certificates?: Yes, we offer EN 10204 3.1/3.2 certificates and third-party inspection from agencies like TUV, BV, Lloyds, SGS, and others.
10. Where are these flanges commonly used?: They are used in power generation, petrochemical, oil & gas, water treatment, and heavy industrial piping systems where large diameter, high-pressure flanges are required.
