The sealing surface of the weld neck flange can be made of smooth type, concavo-convex type and tongue and groove type. The smooth application of smooth butt weld neck flange is most suitable for medium conditions such as low-pressure non-purified compressed air, Low pressure circulating water, its advantage is the price is cheaper. The butt is suitable for pipelines with high pressure or temperature fluctuations or high temperature, high pressure and low temperature piping, and is also used to transport expensive, flammable and explosive media.
