First, JIS B2220 is a steel flange standard widely used in Japan. According to this standard, the nominal pressure of steel flanges can be divided into three levels: 10K, 16K and 20K. This standard specifies the shape, size and connection mode of flanges, as well as related material requirements and inspection methods. It ensures the tightness and reliability of flanged connections and is suitable for different industrial fields.

Japanese standard steel pipe flange is a common pipe connection, and its manufacturing standard is crucial to the safety and reliability of the pipeline system. The Japanese Industrial Standardization Organization has developed several standards for steel pipe flanges for different types and pressures to ensure that their manufacturing process complies with the specifications.

Second, JIS B2238 is a standard for axially sealed welded flanges with nominal pressures of 2K and 5K. This type of flange plays an important role in some special applications, which ensures the safety and reliability of the system by welding the piping system and using an axial seal design.

In addition, JIS B2291 and JIS B2292 are two standards for high pressure flanges. JIS B2291 is suitable for high pressure spiral connection flanges with nominal sizes from 10A to 150A, while JIS B2292 is suitable for high pressure smooth connection flanges with nominal sizes from 50A to 300A. These standards have strict requirements for high pressure piping systems, including the size of the flange, material, connection and sealing performance.

In general, selecting the appropriate manufacturing standard for steel pipe flanges is an important part of ensuring the safe and reliable operation of pipe systems. Different standards are suitable for different types and pressures of pipe connections, depending on the specific pipe application and pressure level, choosing the right standard can ensure the maximum performance and reliability of the pipe. Following these standards, the pipeline system can operate properly and meet the relevant safety requirements, thus ensuring the smooth operation of industrial production.
