Kuchokera kutanthauzira kwaflange, tingadziwe kuti pali mitundu yambiri yaflange, ndipo gulu lake liyenera kukhala losiyanitsidwa ndi miyeso yosiyanasiyana.Mwachitsanzo, malinga ndi njira yolumikizira, flange ikhoza kugawidwaflange yofunika,flat kuwotcherera flange,matako kuwotcherera flange,flange yomasukandi tmtundu wa flange, omwenso ndi flange wamba.

Integral flange (IF)Nthawi zambiri amagwiritsidwa ntchito popanga mapaipi okhala ndi kuthamanga kwambiri.Ndi mtundu wa flange kugwirizana mode, ndipo ali ndi khosi lalitali.Nthawi zambiri amapangidwa ndi nthawi imodzi yophatikizika, ndipo zinthu zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala zitsulo za carbon, zitsulo zosapanga dzimbiri, etc.

Flange kuwotcherera flangeamadziwikanso kuti tower welding flange.Imamalizidwa ndi kuwotcherera polumikizana ndi chotengera kapena payipi.Mtundu woterewu wa flange wowotcherera uli ndi mawonekedwe a msonkhano wosavuta komanso mtengo wotsika.Amagwiritsidwa ntchito makamaka papaipi ndi kupanikizika kochepa komanso kugwedezeka.

Kuwotcherera matako flangeamadziwikanso kuti high khosi flange.Kusiyana kwakukulu pakati pa flange yowotcherera matako ndi ma flanges ena ndikuti ili ndi khosi lalitali lotuluka.Makulidwe a khoma la khosi lalitali lotuluka pang'onopang'ono lidzakhala lofanana ndi makulidwe ndi m'mimba mwake wa khoma la chitoliro kuti likhale lopangidwa ndi kutalika, zomwe zidzawonjezera mphamvu ya flange.Butt welded flange imagwiritsidwa ntchito makamaka m'malo omwe ali ndi kusintha kwakukulu kwa chilengedwe, monga kutentha kwambiri, kuthamanga kwambiri komanso payipi yotsika kutentha.

Kutaya flangeamadziwikanso kuti looper flange.Mtundu uwu wa flange umagwiritsidwa ntchito kwambiri pazitsulo zina zopanda chitsulo ndi zitsulo zosapanga dzimbiri, ndipo kugwirizanako kumachitika ndi kuwotcherera.Ikhoza kuzunguliridwa.Ndipo ndikosavuta kugwirizanitsa dzenje la bawuti, motero limagwiritsidwa ntchito kwambiri polumikiza mapaipi akulu akulu ndipo nthawi zambiri amafunikira kupasuka.Komabe, kukana kwamphamvu kwa flange yotayirira sikuli kwakukulu.Choncho chitha kugwiritsidwa ntchito polumikiza payipi yotsika kwambiri.

Pali mitundu inambale ya flangechaulusi flange, zomwe zimafuna kuti chitoliro chamkati chimakhalanso ndi ulusi wakunja kuti uzindikire kugwirizana.Ndi flange yopanda kuwotcherera, kotero ili ndi ubwino wa unsembe ndi disassembly yabwino poyerekeza ndi flange zina kuwotcherera.M'malo otentha kwambiri kapena otsika, flange yokhala ndi ulusi siyenera kugwiritsidwa ntchito, chifukwa ulusiwo ndi wosavuta kutulutsa pambuyo pa kufalikira kwa kutentha ndi kuzizira kozizira.
