Flange ndi gawo lopangidwa ndi diski, lomwe limapezeka kwambiri mu engineering ya mapaipi, ma flanges amagwiritsidwa ntchito awiriawiri.Popanga mapaipi, Flanges amagwiritsidwa ntchito makamaka polumikizira mapaipi.M'mapaipi omwe amafunika kulumikiza, Zida zosiyanasiyana zimaphatikizapo flange.opereŵera-Kupanikizika mapaipi angagwiritse ntchito waya flanges ndi kuwotcherera flanges ndi mavuto aakulu kuposa 4 kg.Onjezani mfundo zosindikizira mkati mwa flanges ziwiri, mutangolimbitsa ndi mabawuti.Ma Flanges okhala ndi zovuta zosiyanasiyana amakhala ndi makulidwe osiyanasiyana ndipo amagwiritsa ntchito mabawuti osiyanasiyana.Pampu yamadzi ndi valavu zikalumikizidwa ku payipi, mbali zina za zidazi zimapangidwiranso mawonekedwe ofanana, omwe amatchedwanso kulumikizana kwa flange.Magawo onse olumikizira omwe amatsekedwa ndi kutsekedwa m'mphepete mwa ndege ziwirizi amatchedwa "flanges".Mwachitsanzo, kugwirizana kwa mapaipi mpweya wabwino, mbali zimenezi angatchedwe "flange mbali".Koma kugwirizana uku ndi mbali chabe ya zipangizo, Monga malemba pakati pa flange ndi mpope, Sikophweka kutchula mpope 'zigawo flange'.Zing'onozing'ono monga ma valve Dikirani, nthawi zonse zimatchedwa 'magawo a flange'.
Ntchito zazikuluzikulu ndi:
1. Lumikizani payipi ndi kusunga ntchito yosindikiza ya payipi;
2. Kuwongolera kusinthidwa kwa gawo lina la mapaipi;
3. Ndi zophweka disassemble ndi fufuzani chikhalidwe mapaipi;
4. Kuthandizira kusindikizidwa kwa gawo lina la mapaipi.

chitsulo chosapanga dzimbiri flange PN
PN ndi kukakamiza mwadzina, kusonyeza kuti unit ndi MPa mu international unit system ndi kgf/cm2 mu engineering unit system.
Kutsimikiza kwa kukakamizidwa mwadzina sikuyenera kukhazikitsidwa kokha pa kukakamiza kwakukulu kogwira ntchito, komanso kutentha kwapamwamba kwambiri kwa ntchito ndi makhalidwe akuthupi, osati kungokhutiritsa kuti kukakamizidwa mwadzina ndi kwakukulu kuposa kukakamiza kugwira ntchito.Mtundu wina wa flange ndi DN, ndipo DN ndi chizindikiro chosonyeza kukula kwa flange.
