How do you use a blind flange?
A blank flange, also known as a blind flange, is a type of flange that is used to close the end of a pipe, vessel, or valve. It is essentially a flat, disk-shaped plate with no center opening, and it is designed to block off a pipeline or a connection point temporarily.
What is a blank flange used for?
Blank flanges are used in pressure testing of piping systems. By installing a blank flange at one end of the system, pressure can be applied, and the system’s integrity can be tested. This is especially useful during construction or after repairs to ensure that the piping system can withstand the intended pressure without leaks.
During construction or modifications to a pipeline, blank flanges can be used as temporary blockages. This allows work to be carried out on a specific section of the system without affecting the overall flow in the rest of the pipeline.
Blank flanges come in various sizes, materials, and pressure ratings, and the choice of a particular blank flange depends on the specifications of the piping system and the conditions under which it will be used.
How do you use a blind flange?
Select a blind flange that matches the size, pressure rating, and material specifications of the piping system or equipment to be installed. Make sure it meets the requirements of your specific application.
Before installation, inspect the blind flange for any damage, defects or irregularities. Make sure the gasket surface is clean and free of debris.
Verify that pipes or openings on equipment are closed and clear of debris. If there is contact or flange surface, make sure it is in good condition.
Place the blind flange where the pipe or equipment terminates, fitting the bolt holes of the blind flange with the bolt holes of the existing flange. The flange of the blind plate should be located at a similar point facing the inside of the pipe or equipment.
