JIS is a Japanese Industrial Standard for flanges. The JIS standard specifies the dimensions, materials, and technical requirements for various types of flanges used in piping systems.

The JIS standard includes several classes of flanges, including JIS 5K, JIS 10K, JIS 16K, JIS 20K, and JIS 40K flanges. The number after “JIS” in each class represents the nominal pressure rating of the flange in kilograms per square centimeter (kgf/cm²).

JIS 5K flanges are designed for low-pressure applications up to 5 kgf/cm², while JIS 10K flanges are suitable for medium-pressure applications up to 10 kgf/cm². JIS 16K flanges can handle higher pressures up to 16 kgf/cm², and JIS 20K flanges are rated for even higher pressures up to 20 kgf/cm².

Finally, JIS 40K flanges are designed for extremely high-pressure applications up to 40 kgf/cm². These flanges are typically used in oil and gas or petrochemical industries.

All JIS Flanges are available in various materials such as carbon steel, stainless steel, and alloy steel, depending on the application and specific requirements.
