Weld neck flange is a kind of disc part in pipe fitting, it is most common in pipeline engineering. Weld neck flange construction is convenient, high flange strength, good bearing conditions. Weld neck flange suitable for high temperature and high pressure and low temperature process pipeline can be the most widely used flange, weld neck flange is used in pairs.In pipeline engineering, weld neck flange is mainly used for the connection of pipes. Install one flange for each pipes that need to be connected.The low pressure pipe  use a wire flange ,use weld neck flange for over 4KG pressure, two pieces of flange with a sealing point ,and then bolt fastening .
