Letlapa, le tsejwang hape joalo ka letlapa. Flange ke karolo e kopanyang li-shafts 'me e sebelisetsoa ho hokahanya liphaephe; Ho boetse ho na le li-flanges tse kenang le ho tsoa ha lisebelisoa, tse sebelisetsoang ho hokahanya lisebelisoa tse peli, tse kang li-flange tsa gearbox. Khokahano ea flange kapa lenonyeletso la flange le bolela khokahano e ka tlosoang e entsoeng ke motsoako oa li-flanges, li-gaskets le liboutu tse hokahaneng hammoho joalo ka sebopeho sa tiiso. Pipeline flange e bua ka flange e sebelisetsoang ho kenya liphaephe lisebelisoa tsa liphaephe, 'me ha e sebelisoa ho lisebelisoa, e bua ka liphahlo tse kenang le tsa ho tsoa tsa lisebelisoa. Ho latela maemo a fapaneng a khatello a li-valve, li-flange tse nang le maemo a fapaneng a khatello li hlophisoa ka har'a liphaephe tsa liphaephe. Ntlheng ena, baenjiniere ba Majeremane ba tsoang Ward WODE ba hlahisa maemo a 'maloa a tloaelehileng a khatello ea flange ho latela litekanyetso tsa machaba:

Ho ea ka ASME B16.5, li-flange tsa tšepe li na le litekanyetso tse 7 tsa khatello: Class150-300-400-600-900-1500-2500 (li-flange tse lumellanang le naha li na le PN0.6, PN1.0, PN1.6, PN2.5, PN4 .0, PN6.4, PN10, PN16, PN25, lintlha tsa PN32Mpa)

Tekanyo ea khatello ea flange e hlakile haholo. Li-flange tsa Class300 li ka mamella khatello e kholo ho feta Class150 hobane li-flange tsa Class300 li hloka ho etsoa ka lisebelisoa tse ngata ho mamella khatello e kholo. Leha ho le joalo, matla a khatello ea li-flange a susumetsoa ke lintlha tse ngata. Tekanyo ea khatello ea flange e hlahisoa ka liponto, 'me ho na le mekhoa e fapaneng ea ho emela tekanyo ea khatello. Mohlala, meelelo ea 150Lb, 150Lbs, 150 #, le Class150 ea tšoana.
