WN Flange factory believes that flange is a kind of disc-shaped part, which is mainly used between pipelines and valves, between pipelines and pipelines, and between pipelines and equipment. It plays the role of mutual connection and sealing, and is generally used in pairs.

　　WN Flange factory According to the different connection methods, flanges can be divided into: integral flanges, flat welding flanges, butt welding flanges, loose flanges and threaded flanges.

　　WN Flange factory Integral flange: It is a flange connection method, which is mostly used in pipelines with high pressure, and is integrated with the equipment, such as valves, and the production process is generally integral casting.

　　Flat welding flange: Also known as tower welding flange, it is a flange connected to a container or pipeline by welding. It has the characteristics of simple structure and easy assembly. It is mostly used in medium and low pressure containers or pipelines with low vibration.

　　WN Flange factory Butt welding flange: also known as high neck flange, the obvious feature is a raised trumpet-shaped high neck, which is suitable for high temperature, high pressure, low temperature or environments with large temperature and pressure fluctuations.

　　Looper flange: Also known as loose flange, it can be made of different materials from containers or pipes, which is convenient for saving precious metals, and is mostly used in stainless steel and non-ferrous metal pipes with low pressure.

　　WN Flange factory Threaded flange: The inner hole of the flange is threaded, and it is matched with the external thread of the pipe to achieve connection without welding. It has the characteristics of convenient installation and maintenance, and can be used in high pressure environments, but it is not suitable for extremely high temperature, extremely low temperature or Environments with drastic temperature changes.
