The neck welded flange (WN Flange) is suitable for various high-temperature and high-pressure pipeline systems, and its common functions include the following aspects:

1. Connecting pipelines: A weld neck flange is a type of pipeline connector commonly used to connect two pipelines used for transporting liquids or gases, serving as a connecting device to ensure the normal flow of liquids or gases.

2. Improve safety: Using welding neck flanges to connect pipelines can improve the safety and stability of the pipeline, and reduce the risk of leakage in the pipeline system.

3. Adaptation to high temperature and high pressure: The welded neck flange can withstand high temperature and high pressure, and is suitable for various high temperature and high pressure working environments to ensure the normal operation of the pipeline system.
