What is a JIS B2220 threaded flange?

A JIS B2220 threaded flange is a type of flange commonly used in piping systems. It is defined by the JIS B2220 standard, which specifies flanges used in Japan for various industrial applications. These flanges are designed with threaded holes to allow for easy installation onto pipes without the need for welding.

Design and Features

The JIS B2220 threaded flange features a set of internal threads on the inside of the flange, enabling it to be screwed onto a matching threaded pipe or fitting. This design eliminates the need for welding, making it easier to install and remove, especially in applications where welding may not be suitable or feasible.

Threaded flanges, including those made to the JIS B2220 standard, are commonly used for medium- to low-pressure systems. They provide a reliable connection for pipes carrying liquids, gases, and other materials, and are often preferred in situations where welding might be difficult due to space constraints or the materials being used.

Material and Applications

JIS B2220 threaded flanges can be made from a variety of materials, such as carbon steel, stainless steel, and alloy steels, depending on the requirements of the specific application. These materials offer excellent strength, corrosion resistance, and durability, ensuring that the flanges perform well under different operating conditions.

These flanges are widely used in industries like oil and gas, water treatment, and chemical processing, where secure, leak-proof connections are crucial.

Advantages of JIS B2220 Threaded Flanges

Ease of Installation: Threaded flanges are easier to install and remove compared to welded flanges, which makes them ideal for systems that require frequent disassembly or maintenance.

No Need for Welding: Since threaded flanges do not require welding, they are ideal for use with materials that cannot be welded easily or when welding is not feasible.

Reliability: When properly installed, threaded flanges provide secure and leak-proof connections, making them suitable for a wide range of applications.

Corrosion Resistance: Depending on the material used, threaded flanges can offer excellent corrosion resistance, making them suitable for harsh environments.

The JIS B2220 threaded flange is a versatile and reliable component in piping systems, offering a secure connection without the need for welding. Its ease of installation, combined with the wide range of materials available, makes it an excellent choice for various industrial applications. Whether used in the oil and gas, water treatment, or chemical industries, the JIS B2220 threaded flange ensures strong, leak-proof connections for safe and efficient operation.
