Understanding JIS B2220 10K Flange Dimensions

When it comes to industrial piping systems, flanges play a critical role in ensuring the integrity and functionality of connections between pipes, valves, and equipment. Among various standards governing flange dimensions and specifications, the Japanese Industrial Standard (JIS) B2220 is of significant importance, particularly for the 10K class flanges. In this article, we will delve into the specifics of JIS B2220 10K flange dimensions, their application, and why they are essential in modern engineering.

What is JIS B2220?

JIS B2220 is a standardized specification established by the Japanese Industrial Standards that outlines the dimensions, pressure ratings, and material requirements for flanges used in piping systems. These flanges are categorized based on their pressure classes, with 10K indicating a specific pressure rating that defines the capabilities and limitations of the flange. The K symbolizes the class rating where flanges can endure a pressure of up to 10 kilograms-force per square centimeter (kgf/cm²) at elevated temperatures.

Dimensions of JIS B2220 10K Flanges

One of the primary aspects to consider when working with JIS B2220 10K flanges is their dimensions, which include outside diameter, bolt circle diameter, number of holes, hole diameter, and thickness. These dimensions are essential for ensuring compatibility with piping systems and other components.

Key Dimensions 1. Outside Diameter (OD) This is the total outer width of the flange, which significantly influences the strength and stability of the connection. For a JIS B2220 10K flange, the OD varies based on the nominal pipe size (NPS). 2. Bolt Circle Diameter (BCD) The diameter of the circle that passes through the centers of the bolt holes. The BCD ensures proper alignment and support for the flange when bolted to another flange or equipment.

3. Number of Holes The number of stud bolt holes varies depending on the size of the flange. For instance, a smaller flange may have fewer holes, while larger flanges require more.

4. Hole Diameter This dimension specifies the diameter of the bolt holes and is crucial for selecting the appropriate bolts that will secure the flange to another structure.

5. Thickness The flange thickness impacts its mechanical strength and ability to handle internal and external pressures.

Using this standardization, engineers can design fittings that align perfectly during installation, reducing the risk of leaks or failures.

Summary of Typical Dimensions To provide a clearer idea of JIS B2220 10K flange dimensions, here are some typical sizes

- 20A (Nominal Size) OD ~ 140 mm, BCD ~ 100 mm, Hole Diameter ~ 16 mm, Thickness ~ 13 mm. - 50A OD ~ 210 mm, BCD ~ 165 mm, Hole Diameter ~ 18 mm, Thickness ~ 16 mm. - 100A OD ~ 320 mm, BCD ~ 270 mm, Hole Diameter ~ 22 mm, Thickness ~ 20 mm.

It is essential to consult the relevant tables and charts to ensure precision when specifying dimensions.

Applications of JIS B2220 10K Flanges
