Flanges ndi zigawo zooneka ngati diski zomwe zimapezeka kwambiri mu engineering ya mapaipi.Flanges amagwiritsidwa ntchito pawiri komanso ndi ma flanges ofanana pa ma valve.Mu engineering ya mapaipi, flange imagwiritsidwa ntchito makamaka polumikizira mapaipi.Pakufunika kulumikiza chitoliro, unsembe zosiyanasiyana flange, otsika kuthamanga chitoliro angagwiritse ntchito waya flange, ntchito oposa 4 makilogalamu kuthamanga welded flange.Ikani gasket pakati pa ma flanges awiri ndikumangirira ndi mabawuti.Ma Flanges azovuta zosiyanasiyana amakhala ndi makulidwe osiyanasiyana ndipo amagwiritsa ntchito mabawuti osiyanasiyana.
Mapampu amadzi ndi ma valve, akalumikizidwa ndi mapaipi, magawo am'deralo a zida izi amapangidwanso mu mawonekedwe ofananirako a flange, omwe amadziwikanso kuti kulumikizana kwa flange.Onse mu ndege ziwiri mu periphery ntchito bawuti kugwirizana pa nthawi yomweyo chatsekedwa mbali kugwirizana, ambiri amatchedwa "flange", monga kugwirizana kwa mpweya chitoliro, mtundu uwu wa mbali angatchedwe "flange kalasi mbali".Koma kugwirizana uku ndi mbali chabe ya zipangizo, monga kugwirizana kwa flange ndi mpope madzi, si bwino kuitana mpope madzi "gawo flange".Zing'onozing'ono, monga mavavu, amatha kutchedwa "magawo a flange".
Chitsulo chosapanga dzimbiri flange gasket ndi mtundu wa mphete zopangidwa ndi zinthu zomwe zimatha kupanga mapindikidwe apulasitiki ndipo ali ndi mphamvu zina.Ma gaskets ambiri amadulidwa kuchokera ku mbale zopanda zitsulo, kapena zopangidwa ndi mafakitale akatswiri malinga ndi kukula kwake, zinthuzo ndi bolodi la asbestosi, bolodi la asbestosi, bolodi la polyethylene, etc.;Komanso mbale yopyapyala yachitsulo (chitsulo chachitsulo, chitsulo chosapanga dzimbiri) asibesito ndi zinthu zina zopanda zitsulo zokulungidwa ndi gasket yachitsulo;Palinso gasket yokhotakhota yopangidwa ndi chilonda chopyapyala chachitsulo chokhala ndi tepi ya asbestos.Wamba mphira gasket oyenera kutentha m'munsimu 120 ℃ nthawi;Asibesitosi mphira gasket ndi oyenera madzi nthunzi kutentha m'munsimu 450 ℃, mafuta kutentha m'munsimu 350 ℃, kupanikizika m'munsimu 5MPa nthawi, kwa TV zikuwononga ambiri, ambiri ntchito ndi asidi- zosagwira asibesitosi bolodi.Pazida zothamanga kwambiri ndi mapaipi, kugwiritsa ntchito mkuwa, aluminiyamu, zitsulo 10, zitsulo zosapanga dzimbiri zopangidwa ndi mtundu wa mandala kapena mawonekedwe ena azitsulo zachitsulo.Kulumikizana m'lifupi pakati pa high pressure gasket ndi kusindikiza pamwamba ndi yopapatiza kwambiri (kukhudzana kwa mzere), ndipo mapeto a processing pakati pa kusindikiza pamwamba ndi gasket ndipamwamba.
Otsika kuthamanga ang'onoang'ono awiri waya flange, kuthamanga ndi otsika kuthamanga awiri lalikulu ndi welded flange, osiyanasiyana kuthamanga flange makulidwe ndi kulumikiza bawuti awiri ndi chiwerengero ndi zosiyana.
