Japanese standard flange

1、 What is a Japanese standard flange

Japanese standard flange, also known as JIS flange or Nissan flange, is a component used to connect pipes or fittings of different specifications. Its main components are flanges and sealing gaskets, which have the function of fixing and sealing pipelines. Japanese standard flanges are standardized products that use JIS B 2220 standard specifications and have internationally standardized characteristics.

2、 The structure and characteristics of Japanese standard flanges

The Japanese standard flange generally consists of two flanges and a sealing gasket. The flange is usually made of steel material, and the sealing gasket is made of rubber, polytetrafluoroethylene, or metal material. Its structure has the following characteristics:

1. flanges are divided into disc flanges and barrel flanges. Disc flanges are suitable for connecting pipelines, while barrel flanges are suitable for connecting valves and equipment.

2. There are various types of sealing gaskets, which have properties such as corrosion resistance, high temperature resistance, and pressure resistance. The selection of sealing gaskets should be based on the pipeline medium and working environment.

3. The Japanese standard flange plate tightly connects the two flanges through bolts, ensuring good mechanical and sealing performance.
