Amapayipi amapayipi akha unqenqema oluphumela ngaphandle kusukela ekugcineni kwepayipi. Zinezimbobo eziningana ezivumela ama-flange amapayipi amabili ukuba ahlanganiswe ndawonye, akha uxhumano phakathi kwamapayipi amabili. I-gasket ingase ifakwe phakathi kwama-flange amabili ukuze kuthuthukiswe uphawu.
Amapayipi amapayipi ayatholakala njengezingxenye ezihlukene ukuze zisetshenziswe ekuhlanganiseni amapayipi. I-flange yepayipi ixhunywe unomphela noma i-semi-unomphela ekupheleni kwepayipi. Ibese isiza ukuhlanganisa nokuhlakazwa kwepayipi kwelinye ipayipi lepayipi.
Ama-flange amapayipi ahlukaniswa ngokuya ngokuthi anamathiselwe kanjani kwipayipi:
Izinhlobo zamapayipi flange zihlanganisa:
- Weld intamo flangesizinqe zishiselwe ekugcineni kwepayipi, zihlinzeka nge-flange elungele izinga lokushisa eliphezulu nokucindezela.
- Ama-flange anemicuube nentambo yangaphakathi (yesifazane), ipayipi elinentambo lifakwe kuyo. Lokhu kulula ukukuhlanganisa kodwa akulungele ukucindezela okukhulu nezinga lokushisa.
- Ama-flange ane-socket-weldedube nembobo engenalutho enehlombe ngaphansi. Ipayipi lishuthekwa embobeni ukuze liqhunyiswe ehlombe bese lishiselwa endaweni ngokushiselwa kwefillet ngaphandle. Lokhu kusetshenziselwa amapayipi amancane obubanzi asebenza ngomfutho ophansi.
- Ama-Slip-on flangesfuthi ube nomgodi ongenalutho kodwa ngaphandle kwehlombe. Ama-weld we-fillet asetshenziselwa ipayipi ezinhlangothini zombili ze-flange.
- Ama-flange agqitshiwe cukuphikiswa kwezingxenye ezimbili; i-stubend kanye ne-backback flange. I-subend i-butt-welded kuze kube sekupheleni kwepayipi futhi ihlanganisa i-flange encane engenazo izimbobo. I-backing flange ingashelela phezu kwe-stubend futhi inikeze izimbobo zokubhotela kwenye i-flange. Lolu hlelo luvumela ukuhlukaniswa ezindaweni ezivaliwe.
- I-flange eyimpumputheama-s awuhlobo lwepuleti elingenalutho eliboshelwe kwelinye i-flange yepayipi ukuze kuhlukaniswe ingxenye yamapayipi noma ukunqamula amapayipi.
