Flange production standard
Flange is a commonly used pipe connector for connecting pipes and equipment and has the characteristics of firm connection and reliable sealing. The production standards of flanges are usually formulated by relevant standard organizations or industry organizations to ensure that the quality, size and performance of flanges meet the requirements. The following are some common flange production standards:
1. ANSI/ASME standard: A standard jointly formulated by the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME), including ANSI/ASME B16.5, ANSI/ASME B16.47, etc., covering the size of the flange, material and pressure rating.
2. DIN standard: The standard formulated by the German Institute for Standardization (DIN), including DIN 2501, DIN 2533, etc., is commonly used in Europe and covers the size, material and pressure level of the flange.
3. JIS standard: The standard formulated by the Japan Industrial Standardization Society (JIS), including JIS B2220, JIS B2210, etc., is commonly used in Japan and covers the size, material and pressure level of the flange.
4. BS standard: The standard formulated by the British Standards Association (BS), including BS 4504, BS 10, etc., is commonly used in the United Kingdom and some Commonwealth countries, covering the size, material and pressure level of the flange.
5. ISO standard: The standard formulated by the International Organization for Standardization (ISO), including ISO 7005, ISO 9624, etc., is an international general standard, covering the size, material and pressure level of the flange.
These standards specify the size of the flange, the arrangement of the bolt holes, the shape of the flange face, the thickness of the flange, the requirements of the material, and the pressure rating of the flange. According to the specific application requirements, it is very important to choose the appropriate flange standard to ensure the reliability and safety of installation and use.
