Descriptions of ANSI/ASME B16.47 SERIES A Weld Neck Flanges and Blind Flanges:
ASME B16.47 is a standard that governs large diameter steel pipe flanges, including blind flanges and weld neck flanges. The standard is divided into two series: Series A and Series B. The previous API 605 flanges are now classified as Series B flanges under ASME B16.47.
This standard applies to flanges ranging from NPS 26 (Nominal Pipe Size) through NPS 60 and provides dimensions and ratings in both metric and inch units.
ASME B16.47 not only includes its own provisions but also incorporates two other related standards: MSS SP-44 (Steel Pipeline Flanges) and API 605 (Large Diameter Carbon Steel Flanges). Consequently, the flanges specified in MSS SP-44 are designated as ASME B16.47 Series A flanges, while those specified in API 605 are categorized as ASME B16.47 Series B flanges within this standard.

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.
