Chojambula chokhazikika pa flangendi mtundu wa flange, womwe umagwiritsidwa ntchito kwambiri mumakampani opanga makina ndipo watamandidwa ndi ogwiritsa ntchito.Nkhaniyi ikupatsirani chidziwitso chatsatanetsatane chazabwino zina za khosi lotsetsereka pa kuwotcherera flange pamafakitale omwe mwasankha ndikulozera:
1. Monga kutsetsereka kwa hubbed pa flange kumakhala ndi khosi lalifupi lalifupi kuposambale flange kuti kuwotcherera,yomwe imadziwika kuti flange ya mbale, kuuma kwa flange kumakhala bwino kwambiri, kotero kungagwiritsidwe ntchito pa mapaipi omwe ali ndi mphamvu zambiri.
2. Khosi lathyathyathya kuwotcherera flange angagwiritsidwe ntchito ndi mitundu yambiri yosindikiza pamwamba kuposa mbale lathyathyathya kuwotcherera flange.M'mapaipi okhala ndi kupanikizika kwakukulu, nkhope ya concave ndi convex kapena nkhope yakufa ingagwiritsidwe ntchito kusindikiza.
3. The khosi lathyathyathya kuwotcherera flange zambiri ntchito otsika kuthamanga kapena sing'anga kuthamanga mapaipi, amene ndi mtundu wabwinoko kuwotcherera.Izi zili choncho chifukwa mapaipi ndi flange zimakhala zoyima komanso zosavuta kuyika, ndipo payipiyo imakhala yovuta kupendekera.
4. Khosi lathyathyathya kuwotcherera flange sikuti amangopulumutsa malo ndi kulemera, komanso amaonetsetsa kuti olowa si kutayikira ndipo ali ndi ntchito yabwino kusindikiza.Chifukwa chomwe kukula kwa flange kumachepetsedwa ndikuti kuchuluka kwa chisindikizo kumachepetsedwa, zomwe zidzachepetsa gawo la malo osindikizira.
(Hubbed Slip Pa Flange) (Plate flange yowotcherera)
Kugwiritsa ntchito kutsetsereka kwa khosi pa kuwotcherera flange ndikokulirapo, ndipo kuchuluka kwa ntchito kumatsimikiziridwa molingana ndi mawonekedwe osiyanasiyana.Ambiri a iwo ntchito pamene sing'anga zinthu ndi wofatsa, monga otsika kuthamanga osayeretsedwa wothinikizidwa mpweya ndi otsika kuthamanga kuzungulira madzi.Ubwino wake ndikuti mtengo wake ndi wotsika mtengo.
khosi lathyathyathya kuwotcherera flange ndi ntchito kwa mwadzina kuthamanga osiyanasiyana, amene nthawi zambiri ntchito kugwirizana kwa 0.6 — 4.0MPa zitsulo mapaipi.Kusindikiza pamwamba pa khosi lathyathyathya kuwotcherera flange kungapangidwe kukhala mitundu itatu: yosalala, mtundu wa concave convex ndi tenon groove.Khosi losalala lathyathyathya flange limagwiritsidwa ntchito kwambiri, ndipo mitundu iwiri ina ya khosi lathyathyathya yowotcherera flange imakonda kugwiritsidwanso ntchito.Ma flange a khosi amaphatikizapo mitundu yambiri ndi zitsanzo.Poyerekeza, kuwotcherera khosi flangesamagwiritsidwa ntchito powotcherera matako a flanges ndi mapaipi.Amagwiritsidwa ntchito kwambiri muukadaulo wazowotcherera, wokhala ndi mawonekedwe abwino komanso magwiridwe antchito.Iwo ali ndi dongosolo loyenera, mphamvu zazikulu ndi kuuma, amatha kupirira kutentha kwakukulu ndi kuthamanga kwakukulu, kupindika mobwerezabwereza ndi kusinthasintha kwa kutentha, ndipo amakhala ndi ntchito yodalirika yosindikiza.Kuthamanga kwawo mwadzina nthawi zambiri kumakhala 1-25MPa.
Komanso, kuwotcherera pakati pa khosi matako kuwotcherera flange ndi nozzle wa M'kalasi B kuwotcherera, pamene kuwotcherera pakati pa khosi lathyathyathya kuwotcherera flange ndi nozzle wa Class C kuwotcherera.Kuyesa kosawononga pambuyo pa kuwotcherera kumasiyana pakati pawo.
