Blind flanges are used to seal the end of high pressure openings. They are commonly used for capping the flow of gas or liquid through a combination of oil and gas products. Blind flanges also allow for easy access to the equipment in case work must be done inside the flow. They are oftentimes used for high pressure applications. Test flanges are commonly known for their 9/16th UNF and ½ inch NPT. While a Blind Flange will commonly not have any holes.
