AEA Blind Flanges are used to seal the end of a piping system or pressure vessel openings to prevent flow. They are commonly used for pressure testing the flow of liquid or gas through a pipe or vessel. They also allow easy access to the pipe in the event that work must be done inside the line. Blind pipe flanges are often used for high pressure applications.
