Blind pipe flanges are pipe flanges used to seal the end of a piping system or pressure vessel openings to prevent flow. Blind pipe flanges are commonly used for pressure testing the flow of liquid or gas through a pipe or vessel. Blind pipe flanges 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. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 96". Coastal Flange provides Blind pipe flanges in all material grades, specifications and sizes. |
Blind pipe flanges are typically provided with a raised face, flat face, or RTJ facing.
