JIS B2220 Flange

JIS B2220 is a Japanese Industrial Standard (JIS) that specifies the dimensions, materials, and technical requirements for steel pipe flanges used in various industrial applications. These flanges are commonly used in Japan and other countries that adopt the JIS standards. The JIS B2220 standard provides a standardized system for the design and manufacture of flanges, ensuring compatibility and interchangeability between different components.

Key features and specifications of JIS B2220 flanges:
1. Flange Types: JIS B2220 defines various types of flanges, including slip-on flanges, blind flanges, weld neck flanges, socket weld flanges, and threaded flanges. Each type serves a specific purpose in pipeline and piping system connections.

2. Pressure Ratings: JIS B2220 flanges are available in different pressure ratings, such as 5K, 10K, 16K, 20K, and 30K. These ratings indicate the maximum pressure the flange can withstand in a given application, with 5K being the lowest and 30K the highest.

3. Materials: The standard specifies the materials for manufacturing JIS B2220 flanges, including carbon steel, stainless steel, and alloy steel. The choice of material depends on the specific requirements of the application, such as resistance to corrosion, temperature, and pressure.

4. Flange Faces: JIS B2220 flanges feature raised face (RF), flat face (FF), and ring type joint (RTJ) flange faces, each suitable for different gasket types and sealing applications.

5. Dimensions: The standard provides detailed dimensions for flanges, including the outer diameter, bolt circle diameter, bolt hole size, and thickness. These dimensions ensure that flanges of the same size and pressure rating are interchangeable.

6. Installation: JIS B2220 flanges are typically installed using bolts and gaskets. The number and size of bolts and the type of gasket depend on the flange type and pressure rating. Proper installation is essential to ensure a leak-free and secure connection.

7. Application: JIS B2220 flanges are commonly used in various industries, including petrochemicals, oil and gas, water treatment, and shipbuilding. They are essential components in piping systems, allowing for the easy assembly and disassembly of pipes and equipment.
