It serves as a terminal closure component, playing a critical role during maintenance, inspection, or system expansion.<\/p>\n<h3>Main Applications<\/h3>\n<ol>\n<li>Pipe Closure: Seal pipe ends to prevent medium leakage<\/li>\n<li>System Isolation: Isolate specific pipe sections during maintenance<\/li>\n<li>Pressure Testing: Closure during pipeline pressure tests<\/li>\n<li>Future Connection: Reserve connection points for pipeline expansion<\/li>\n<\/ol>\n<h3>Structural Features<\/h3>\n<ul>\n<li>Solid construction with no center hole<\/li>\n<li>Thicker than other flanges of same specification<\/li>\n<li>Bolt connection to mating flange<\/li>\n<li>Available in RF, FF, or RTJ sealing faces<\/li>\n<\/ul>\n<h3>Types<\/h3>\n<ul>\n<li>Standard Blind: Regular thickness<\/li>\n<li>Heavy Duty Blind: For higher pressure<\/li>\n<li>Spectacle Blind: One side blind, one side ring for frequent switching<\/li>\n<li>Spade Blind: Inserted between mating flanges<\/li>\n<\/ul>\n<h3>\u062a\u0635\u0646\u064a\u0641\u0627\u062a \u0627\u0644\u0636\u063a\u0637<\/h3>\n<p>Class 150-2500 (ASME) or PN6-PN100
