These pipe flanges are used to seal the end of piping systems or pressure vessel openings. They are commonly used for testing the flow of gas or liquid through a pipe or vessel. Blind pipe flanges also allow for easy access to the pipe in case work must be done inside the line. They are oftentimes used for high pressure applications. Slip on Pipe flanges with a hub have published specifications that range from 1/2″ thru 96″. We provide these types of flanges in all material grades, specifications and sizes.
Blind pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for blind pipe flanges, the standard height is 1/16″ for blind pipe flanges under 400#. For blind pipe flanges of 400# and up, the standard blind pipe flange raised face height is 1/4″.
