ASTM A182 F304L / UNS S30403 / 1.4306 BLRF Stainless Steel Blind Flange
Stainless steel 304L blind flanges are commonly used in piping systems to seal the end of a pipeline or a valve. Stainless steel 304L blind flanges can be used in high-temperature and high-pressure applications, as they have excellent resistance to corrosion and oxidation. Blind flanges are also known as blanking flanges, and they are used to close off the end of a pipe or fitting.
