Li-flange tse tloaelehileng tse ka sehloohong ke li-flange tse cheselitsoeng tse bataletseng le li-flange tse cheselitsoeng ka butt. Gasket e tloaelehileng ea rabara e loketse mocheso o ka tlase ho 120 ℃; Asbestos rabara gasket e loketse mocheso oa mouoane oa metsi o ka tlase ho 450 ℃, mocheso oa oli o ka tlase ho 350 ℃, khatello e ka tlase ho 5MPa, bakeng sa mokhoa o tloaelehileng oa ho senya, o sebelisoang haholo ke boto ea asbestos e hanyetsanang le acid.
Tlaase khatello e nyenyane bophara terata kgokagantswe flanges, khatello e phahameng le khatello e tlaase bophara bophara ba welded flanges, flange botenya le hokahanya bolt bophara le palo ea likhatello tse fapaneng li fapane.
Li-gaskets tse ngata li khaotsoe ho tloha lipoleiti tse seng tsa tšepe, kapa li entsoe ke lifeme tsa litsebi ho ea ka boholo bo boletsoeng, thepa ke boto ea rabara ea asbestos, boto ea asbestos, boto ea polyethylene, joalo-joalo; Hape e na le thuso ea tšepe e tšesaane (lakane ea tšepe, tšepe e sa hloekang) asbestos le lisebelisoa tse ling tse se nang tšepe tse phuthetsoeng tse entsoeng ka likhase tsa tšepe; Ho boetse ho na le mofuta oa leqeba la gasket le entsoeng ka theipi e tšesaane ea tšepe le leqeba la asbestos hammoho.
