Ulusi wa flange ndi flange wosamangika, womwe umalumikizidwa ndi chitoliro cha ulusi pokonza dzenje lamkati la flange kukhala ulusi wa chitoliro.Poyerekeza ndi lathyathyathya kuwotcherera flange kapena matako kuwotcherera flange, ulusi flange ali ndi makhalidwe ya unsembe yabwino ndi kukonza, ndipo angagwiritsidwe ntchito mipope amene salola kuwotcherera munda.Aloyi chitsulo flange ali ndi mphamvu zokwanira, koma si kophweka kuwotcherera, kapena kuwotcherera ntchito si bwino, ulusi flange akhoza kusankhidwa.Komabe, kutentha kwa chitoliro chikasintha mwachangu kapena kutentha kuli kopitilira 260 ° C koma kutsika kuposa -45 ° C, tikulimbikitsidwa kuti musagwiritse ntchito flange ya ulusi kuti mupewe kutayikira.

Chophimba cha Flange chimatchedwanso blind flange, mbale yakhungu.Iyi ndi flange yopanda dzenje pakati, yomwe imagwiritsidwa ntchito kusindikiza pulagi ya chitoliro.Ntchitoyi ndi yofanana ndi ya welded olowa ndi ulusi chitoliro kapu.Kusiyana kwake ndikuti flange yakhungu ndi kapu ya chitoliro yolumikizidwa imatha kuchotsedwa nthawi iliyonse, koma mutu wowotcherera sungathe kuchotsedwa.Pali mitundu yambiri ya malo osindikizira, kuphatikizapo athyathyathya, otukumula, opindika ndi opingasa, malo a tenon ndi groove komanso malo olumikizana ndi annular.

American standard flanges ndi zigawo zomwe zimagwirizanitsa mapaipi ndi mapaipi ndi mapeto a mapaipi.Ma flanges aku America omwe amawotcherera matako amapangidwa ndikupangidwa m'njira ziwiri.American muyezo matako kuwotcherera flange akhoza kugawidwa mu khosi American muyezo matako kuwotcherera flange ndi sanali khosi American muyezo matako kuwotcherera flange malinga ndi mikhalidwe ya khosi.American standard butt welding flange imakhala ndi mbale ziwiri za flange ndi ma flange gaskets.Mawotchi a Flange amangiriridwa palimodzi kuti amalize kulumikizana.American flange ili ndi mabowo, ndipo mabawuti amalumikiza ma flange awiri mwamphamvu.Flange imasindikizidwa ndi gasket.
