Flanges, kapena ma flanges, ndi ma symmetrical disk-ngati ma diski omwe amagwiritsidwa ntchito kulumikiza mapaipi kapena zida zomangira shaft.Nthawi zambiri amakonzedwa ndi ma bolts ndi ulusi.Kuphatikizapo chigongono cha flange ndi chitsulo chosapanga dzimbiri, ndikuwonetseni mwachidule kulumikiza kwa flange ndi chitoliro cha njira zingapo.
Mtundu woyamba:lathyathyathya welded zitsulo flange
Flat welded zitsulo flangesndi oyenera kugwirizana kwa mipope mpweya zitsulo amene kuthamanga mwadzina si kuposa 2.5Mpa.Kusindikiza pamwamba paflat welded zitsulo flangesitha kupangidwa kukhala yosalala, mtundu wa concave-convex ndi mtundu wa tenon groove.Ntchito kuchuluka kwa yosalalaflat-welded flangeamagwiritsidwa ntchito makamaka pazikhalidwe zapakatikati, monga mpweya woponderezedwa wosayeretsedwa komanso madzi ozungulira otsika.Ubwino wake ndikuti mtengo wake ndi wotsika mtengo.
Chachiwiri, matako-welded zitsulo flange
Matako-kuwotcherera zitsulo flangekwa flange ndi kuwotcherera chitoliro, kapangidwe kake ndi wololera, mphamvu ndi stiffness lalikulu, akhoza kupirira kutentha ndi kuthamanga mkulu ndi mobwerezabwereza kupinda ndi kusinthasintha kutentha, odalirika kusindikiza, mwadzina kuthamanga kwa 0,25 ~ 2.5Mpa matako-kuwotcherera flange ntchito concave ndi otukukira kusindikiza kusindikiza pamwamba.
Chachitatu, socket kuwotcherera flange
Socket welding flanges nthawi zambiri amagwiritsidwa ntchito pamapaipi okhala ndi PN≤10.0MPa ndi DN≤40.

Mtundu wachinayi, flange ya manja omasuka
Flange ya manja omasukaimadziwika kuti looper flange, yomwe imagawidwa kukhala wowotcherera mphete looper flange,flange looper flangendi matako kuwotcherera looper flange.Nthawi zambiri ntchito sing'anga kutentha ndi kuthamanga si mkulu ndi sing'anga dzimbiri ndi wamphamvu.Sing'angayo ikapsa kwambiri, mbali ya flange yomwe imalumikizana ndi sing'anga (flanged nipple) ndi zida zapamwamba monga chitsulo chosapanga dzimbiri chomwe sichimamva dzimbiri, pomwe mbali yakunja imamangidwa ndi mphete ya flange ya zinthu zotsika kwambiri. ngati chitsulo cha carbon kuti mukwaniritse kusindikiza.
Chachisanu, integral flange
Integral flangesnthawi zambiri flanges ndi zipangizo, mapaipi, zovekera chitoliro, mavavu, etc., anapanga kukhala chimodzi, mtundu uwu amagwiritsidwa ntchito zida ndi mavavu.
Kukumbutsa aliyense, chifukwa cha chitsulo chosapanga dzimbiri flange chigongono ndi chubu sleeve kugwirizana njira ndi osiyana, ndondomeko makhalidwe ndi osiyana kwambiri, tikhoza kusankha malinga ndi zosowa zawo zenizeni kusankha zigawo zoyenera flange, musakhale aumbombo kwa mphindi mtengo. ndi ngozi zodziwika bwino zachitetezo pamapaipi onse.
