ASME B16.47 SER.B API605 CLASS150 Carbon steel blind flange
Description
Carbon steel blind flange is a flange without hole in the middle, which is used to seal the pipe plug. The function is the same as that of welded head and threaded pipe cap, except that blind flange and threaded pipe cap can be removed at any time, while welded head cannot.
Carbon steel blind flange is easy to use and can withstand large pressure. Carbon steel blind flange is widely used in industrial pipeline. In the family, if the pipe diameter is small and low pressure, the blind flange is not commonly used, but the threaded pipe cap is used.
