About JIS Standards
JIS (Japanese Industrial Standards) are national standards in Japan that are developed and reviewed by the Japanese Industrial Standards Committee (JISC). These standards are among the most important and authoritative in Japan. JIS covers a broad range of industrial fields, including civil engineering, machinery, electrical appliances, automotive, steel, non-ferrous metals, chemicals, textiles, paper, medical safety equipment, aviation, and information technology.
JIS standards are divided into 19 categories, with over 10,000 active standards in place as of 2007. The JIS standard system includes product standards (such as shape, size, quality, performance), method standards (such as testing, analysis, measurement), and basic standards (such as terms, symbols, and units).
About Flanges
A flange is a mechanical component used to connect pipes, valves, pumps, and other equipment. Flanges are widely used in pipeline systems to connect two components securely. They typically consist of a flange plate, gasket, and bolts, which form a detachable sealing structure. Flanges are used to connect pipes or other devices and are available in various types: threaded flanges, welded flanges, and clamp flanges.
Flanges are usually paired for connection, and the pressure rating determines the thickness and bolt size. Low-pressure pipelines can use threaded flanges, while welded flanges are used for higher pressure applications. The gasket in between the two flanges ensures a secure and leak-proof connection. Various types of flanges are used in different industries, including pumps and valves, where they are matched to the required flange shape and pressure rating.
