[0001] The utility model relates to the field of flanges with good sealing performance for glass fiber reinforced plastic storage tanks, in particular to a flange with good sealing performance. Background Art

[0002] Flanges are used in pairs, and are parts that connect shafts to each other. They are a common way to connect pipes, connecting different pipes, equipment or accessories. In many applications, flange connections need to have good sealing properties to prevent fluid leakage or external media from entering the system.
