Blind flanges, also known as blank flanges or dummy flanges, are a type of flange that is used to seal the end of a pipe or a valve. Blind flanges are typically round or square in shape and have no opening in the center. They are attached to the pipe or valve using bolts and nuts, creating a tight and secure seal.

Blind flanges are commonly used in applications where there is a need to close off a section of a piping system or a valve. They are also used as test caps to check the pressure and integrity of a pipeline during hydrostatic testing.

Blind flanges are available in a wide range of materials, including carbon steel, stainless steel, and various alloys. The choice of material will depend on the specific application and the requirements for strength, corrosion resistance, and other properties.

Blind flanges are commonly used in industries such as oil and gas, chemical processing, and power generation. They are also used in applications where cleanliness and hygiene are critical, such as in the food and pharmaceutical industries.
