PN10 DN50 Blind Flanges

Yes, you are correct. A blind flange, also known as a blank flange or flange blind plate, is a type of flange that has a solid plate with a bolt pattern on one side and a gap or opening in the middle. It is used to block the end of a pipeline or vessel, effectively closing it off and preventing the flow of fluids.One of the main purposes of a blind flange is to provide a temporary or permanent seal to isolate a section of the pipeline. This can be useful during maintenance, repair, or when a specific section of the pipeline needs to be blocked off. By using a blind flange, any potential leakage or fluid flow can be avoided.Blind flanges are different from other types of flanges, such as welding neck or slip-on flanges, as they do not have an opening or connection for a pipe or fitting. The blind plate is typically attached to the pipeline or vessel by bolts, allowing for easy installation and removal when necessary.Blind flanges come in various materials, including carbon steel, alloy steel, stainless steel, and even plastic, depending on the specific application requirements. The material choice is influenced by factors such as pressure, temperature, corrosion resistance, and the type of fluid or substance being transported.In summary, blind flanges are a specialized type of flange used to close off the end of a pipeline or vessel. They provide both sealing and easy removal capabilities, making them convenient for maintenance and temporary closure purposes.
