Characteristics and Construction of JIS 10K Flange:
1. Shape and Design:
- JIS 10K flanges have a round shape with bolt holes around the perimeter for mounting to pipes or other components. These flanges are designed with a flat face or a raised face (RF), depending on the application and the type of gasket used.
- Raised Face (RF) is a common design for JIS 10K flanges to increase the contact area with the gasket, ensuring a tighter connection and preventing leaks.
2. Materials:
- JIS 10K flanges can be made from a variety of materials depending on the application and the type of fluid being transported. The most common materials include:
- Carbon Steel: Carbon steel flanges are an economical and strong choice for many low- to medium-pressure applications.
- Stainless Steel: For applications requiring corrosion or high-temperature resistance, stainless steel is often used.
- Alloy Steel: Used for applications with very high pressures or temperatures.
- PVC, CPVC, and Plastic Materials: Used for special applications, such as chemical pipes or clean water piping systems.
3. Size and Classification:
- JIS 10K flanges are available in various sizes to suit the pipe diameter and required application. These flange sizes typically comply with the JIS B2220 standard, which regulates the dimensions and classification of pipe flanges in Japan.
- JIS 10K flanges also have standardized thicknesses and bolt hole diameters and can be used for various types of pipe and equipment connections.
4. Connection Type:
- JIS 10K flanges can be used for various connection types, such as butt welds (welding the pipe directly to the flange), socket welds (the pipe is inserted into the flange socket and welded), and threaded flanges (threaded flanges used on pipes that also have threads).
5. Gaskets and Installation:
- To create a tight and secure connection, JIS 10K flanges are typically installed with gaskets tailored to the flange material and size. Commonly used gaskets are rubber, metal, or graphite gaskets, depending on the application requirements.
- Bolts used to connect flanges to pipes or other equipment must be strong enough to withstand the pressure exerted by the fluid in the pipe.
