Whtat is Stainless Steel Blind Flange?
A Stainless Steel Blind Flange is a type of pipe flange that is used to shut off or block the end of a pipe or vessel. It is a solid disk or plate with a bolt hole in the center and a raised face on one side. The raised face creates a tight seal when the flange is attached to the end of a pipe or vessel using bolts. Blind flanges are typically used in piping systems where the end of a pipe needs to be blocked off for maintenance or safety purposes. They are popular in industries such as oil and gas, chemical, and pharmaceuticals because they offer a tight and secure seal that is resistant to corrosion and high temperatures. Stainless steel is a popular material choice for blind flanges because of its durability, resistance to corrosion, and ability to withstand high pressure and temperature environments.
