A weld neck flange is categorized into two types: one used in pipes, and a long flange used in process plants. The second type is not suitable for pipelines. Our weld neck flanges used in pipes are able to withstand both high and low temperatures, high pressure, and temperature fluctuations. They are normally used to connect a nominal pressure class (PN) of more than 2.5MPA in pipes and valves, and are often used to transport flammable and explosive media through a pipeline.
