Descriptions of ANSI/ASME B16.47 SERIES A Weld Neck Flanges and Blind Flanges:
ASME B16.47 is a standard for large diameter steel pipe flanges, which is further divided into two series: Series A and Series B. The standard covers blind flanges and weld neck flanges. Series B flanges were previously referred to as API 605 flanges.
ASME B16.47 specifies the dimensions and ratings for flanges sized from NPS 26 (Nominal Pipe Size) through NPS 60. The standard provides both metric and inch units for dimensions and ratings.
The ASME B16.47 standard incorporates two other standards: MSS SP-44 (Steel Pipeline Flanges) and API 605 (Large Diameter Carbon Steel Flanges). As a result, MSS SP-44 flanges are designated as ASME B16.47 Series A flanges, while API 605 flanges are designated as ASME B16.47 Series B flanges within this standard.

Features of ASME B16.47 Carbon Steel Weld Neck Flanges and Blind Flanges:
ANSI B16.47 Series A flanges are large diameter steel flanges designed and manufactured according to the specifications outlined in the ANSI B16.47 standard:
Size Range: ANSI B16.47 Series A flanges are available in nominal sizes ranging from 26 inches to 60 inches. These flanges are specifically designed for larger pipe connections.
Pressure Ratings: ANSI B16.47 Series A flanges are designed to withstand high-pressure applications. The pressure ratings for Series A flanges typically range from Class 150 to Class 900. The pressure rating determines the maximum allowable pressure that the flange can handle.
Facing Types: ANSI B16.47 Series A flanges can have different facing types, including raised face (RF) and ring-type joint (RTJ). The facing type determines the sealing surface and the compatibility with gaskets.
Bolt Holes: ANSI B16.47 Series A flanges have a specific number of bolt holes depending on the flange size and pressure rating. The bolt holes are used to attach the flange to the mating flange or equipment using bolts.
Materials of Construction: ANSI B16.47 Series A flanges are typically made from carbon steel, alloy steel, or stainless steel, depending on the application requirements. The material selection ensures the flanges' strength, corrosion resistance, and compatibility with the process fluid or gas.
Standards Compliance: ANSI B16.47 Series A flanges comply with the standards set by the American National Standards Institute (ANSI). Compliance with these standards ensures the interchangeability and compatibility of flanges manufactured by different vendors.
Grades of Carbon Steel Flanges:
American standard carbon steel flanges are flanges made of carbon steel and are widely used in industries such as petroleum, chemical, natural gas, shipbuilding, construction, and water conservancy. Its carbon steel grades are usually divided into the following parts:
1.Q235: Q235 is a commonly used carbon structural steel grade specified in the Chinese national standard GB/T 700. It is often used in general engineering structures and manufacturing industries. In carbon steel flanges, Q235 material is commonly used for pipeline systems operating at low pressure, low temperature, and non-critical stress environments.
2.A105: A105 is a carbon steel material specified in the American ASTM standard, complying with ASTM A105/A105M requirements. A105 material has good weldability and mechanical properties, making it suitable for use in a wide temperature range from low to high temperatures. It is commonly used for pipeline systems and valve connections under high temperature and high-pressure conditions.
3.A350 LF2: A350 LF2 is also a carbon steel material specified in the ASTM standard, complying with ASTM A350/A350M requirements. LF2 indicates low-temperature service, and this material has good low-temperature toughness and crack resistance. It is commonly used for pipeline systems and valve connections under low-temperature conditions.
4.A694 F42/F52/F60/F65/F70: These material grades are specified in the ASTM A694 standard for carbon steel materials used in high-strength, low-temperature, or normal temperature high-pressure pipeline systems and valve connections. Different grades of materials have different strengths and corrosion resistance properties, suitable for various working conditions.
5.ASTM A181 Gr.1/Gr.2: These carbon steel flange material grades are suitable for pressure vessels, valves, and pipeline fittings under low pressure and low temperature conditions. They have good machinability and mechanical performance.
6.ASTM A516 Gr.70: Gr.70 is a commonly used medium carbon steel grade, known for its good weldability and machinability, suitable for manufacturing flanges and pipe fittings, among others.
7.A216 WCB: A216 WCB is a carbon steel casting material specified in the American ASTM standard, complying with ASTM A216/A216M requirements. WCB stands for cast carbon steel, and it is commonly used for carbon steel flanges that require casting in general engineering structures and manufacturing industries.
These material grades mentioned above are only a part of the commonly used ones, and there are other material grades in practical applications. When selecting the material grade for carbon steel flanges, it is necessary to consider engineering requirements, temperature, pressure, medium, and the requirements of relevant standards to ensure that the flange material meets the corresponding performance and safety requirements.
