Flange Classification:
1. Lisebelisoa tsa Flange: tšepe ea carbon, tšepe e entsoeng ka tšepe, tšepe ea alloy, tšepe e sa hloekang, koporo le motsoako oa aluminium.
2. Ka mokhoa oa ho etsa lihlahisoa, e ka aroloa ka flange e entsoeng ka maiketsetso, flange e entsoeng, e nang le welded flange, joalo-joalo.
3. Ho ea ka tekanyo ea tlhahiso, e ka aroloa ka maemo a naha (GB) (Lekala la maemo a indasteri ea lik'hemik'hale, maemo a petroleum, motlakase oa motlakase), American Standard (ASTM), German standard (DIN), Japanese standard (JB) , joalo-joalo.

Sesebelisoa sa Flange
Flat welded steel flange:e loketseng bakeng sa khokahano ea phala ea tšepe ea carbon le khatello ea lebitso e sa feteng 2.5Mpa.Bokaholimo ba tiiso ea flange e bataletseng ea welding e ka etsoa ka mefuta e meraro: mofuta o boreleli, mofuta oa concave-convex le mofuta oa leleme-le-groove.Ts'ebeliso ea flange e boreleli ea tjheseletsa ke eona e kholo ka ho fetisisa, 'me e sebelisoa haholo maemong a mahareng a mahareng, joalo ka moea o hatelitsoeng o sa hloekang oa khatello e tlase le metsi a potolohang ka khatello e tlase.Molemo oa eona ke hore theko e batla e le theko e tlaase.
Butt welding steel flange:E sebelisetsoa ho cheselletsa butt ea flange le phala.E na le sebopeho se utloahalang, matla a phahameng le ho tiea, e khona ho mamella mocheso o phahameng le khatello e phahameng, ho khumama khafetsa le ho feto-fetoha ha mocheso, 'me e na le ts'ebetso e tšepahalang ea ho tiisa.The butt welding flange e nang le khatello ea lebitso la 0.25-2.5Mpa e nka sebaka se tiisitsoeng sa concave-convex.
Socket welding flange:e sebelisoang hangata liphaepheng tse nang le PN≤10.0Mpa le DN≤40;
Li-flange tse hlephileng:li-flange tse hlephileng hangata li tsejoa e le li-looper flanges, li-welding ring ring looper flanges, li-flanging looper flanges le butt welding looper flanges.Hangata e sebelisoa tabeng eo mocheso o bohareng le khatello e sa phahametseng 'me bohareng bo senya haholoanyane.Ha sehare se senyeha ho feta, karolo ea flange e kopanang le medium (flanging short joint) e entsoe ka thepa ea boemo bo holimo e thibelang ho bola joalo ka tšepe e sa hloekang, 'me ka ntle e hatelloa ke mehele ea flange ea thepa ea boemo bo tlaase e kang. tšepe ea carbon.ho fihlela tiiso;
Integral flange:Hangata flange e kopantsoe le lisebelisoa, liphaephe, li-valve, joalo-joalo Mofuta ona o atisa ho sebelisoa ka thepa le li-valve.
