ASTM A182 blind flanged is used to connect with two pipes. Pipe is fixed on a flange. Then put a gasket between flanges and using bolt to fasten together. Blind flange can be sorted into threaded blind flange and welding blind flange. Welding blind flange is used for high pressure large diameter pipe while threaded blind flange can be only used for low pressure small diameter pipe.
