I-Flange enezintambo

I-Flange ibizwa nangokuthi i-flange noma i-flange.

Ingxenye exhuma ipayipi kanye nepayipi komunye nomunye ixhunywe ekupheleni kwepayipi.Kunezimbobo kuma-flange, futhi amabhawodi enza ama-flange amabili axhumeke ngokuqinile.Ama-flanges avaliwe ngama-gaskets.Ukufakwa kwamapayipi ane-flanged kubhekisela ekufakweni kwamapayipi ngama-flanges (ama-lugs noma amasokhethi).Ingenziwa ngokusakazwa (engaboniswa esithombeni), noma ingakhiwa ngokuxhuma okunentambo noma ukushisela.Ukuxhumeka kwe-Flange (i-flange, i-joint) iqukethe ama-flanges, i-gasket nama-bolts amaningana namantongomane.I-gasket ibekwe phakathi kwezindawo zokuvala zama-flange amabili.Ngemva kokuqinisa i-nati, ingcindezi ethile endaweni ye-gasket ifinyelela inani elithile futhi ikhubaze futhi igcwalise ukungalingani kwendawo yokuvala ukuze wenze ukuxhumana kuqine futhi kungabonakali ukuvuza.Uxhumano lwe-Flange luwuxhumano olususekayo.Ngokusho kwezingxenye ezixhunyiwe, ingahlukaniswa ibe yi-container flange ne-pipe flange.Ngokusho kohlobo lwesakhiwo, kukhona ama-flanges abalulekile, ama-flange avulekile kanye nama-flanges anezintambo.Ama-flange ajwayelekile ahlanganisa ama-flange welding flat kanye nama-flange welding we-butt.Ama-flange ashiselwe phansi anokuqina okubuthakathaka futhi afanele izikhathi ezinengcindezi p≤4MPa;ama-flange ane-butt-welded abizwa nangokuthi ama-flange aphezulu anentamo eqinile futhi afanelekele izikhathi ezinengcindezi ephakeme kanye nezinga lokushisa.Kunezinhlobo ezintathu ze-flange yokubekwa uphawu kwendawo: indawo eyisicaba yokuvala, efanelekile ngezikhathi ezinomfutho ophansi kanye nemidiya engenabuthi;i-concave-convex sealing surface, ifanele izikhathi ezinengcindezi ephakeme kancane;ulimi kanye nendawo yokuvala imisele, ilungele ukuvutha nokuqhuma , Imidiya enobuthi kanye nezikhathi zokucindezela okukhulu.I-gasket iyindandatho eyindilinga eyenziwe ngezinto ezingakhiqiza ukuguqulwa kwepulasitiki futhi inamandla athile.Iningi lama-gaskets lisikwa kumapuleti angewona awensimbi, noma enziwe amafektri ochwepheshe ngokuya ngosayizi oshiwo.Izinto zokwakha amapuleti enjoloba ye-asbestos, amapuleti e-asbestos, amapuleti e-polyethylene, njll.;amapuleti ensimbi amancane (insimbi emhlophe, insimbi engagqwali) asetshenziselwa ukususa i-asbestos I-gasket ehlanganiswe ngensimbi eyenziwe ngezinto ezingezona ezensimbi;kukhona futhi i-gasket yesilonda esivunguzayo eyenziwe nge-tape yensimbi encane kanye ne-asbestos tape.Ama-gasket enjoloba avamile afanele izikhathi lapho izinga lokushisa lingaphansi kuka-120°C;ama-gasket enjoloba ye-asbestos afanele izikhathi lapho izinga lokushisa lomhwamuko lingaphansi kuka-450°C, izinga lokushisa likawoyela lingaphansi kuka-350°C, futhi ukucindezela kungaphansi kuka-5MPa, futhi ngokuvamile kugqwala.Indawo esetshenziswa kakhulu ibhodi le-asbestos elingazweli ne-asidi.Emishinini yokucindezela okukhulu namapayipi, ama-gaskets ensimbi ohlobo lwe-lens noma ezinye izimo ezenziwe ngethusi, i-aluminium, insimbi engu-10, nensimbi engagqwali.Ububanzi bokuxhumana phakathi kwe-gasket ye-high-pressure kanye nendawo yokuvala incane kakhulu (ukuxhumana komugqa), futhi ukuphela kokucubungula kwendawo yokuvala kanye ne-gasket kuphakeme kakhulu.

I-flange ihlukaniswe ngoxhumano oluhlanganisiwe (uxhumano lwezintambo) i-flange, i-welding flange kanye ne-clamping flange.Kukhona ama-wire flanges nama-ferrule flange amadayamitha amancane anengcindezi ephansi.Ama-flange ashiselwe asetshenziselwa ukucindezela okuphezulu kanye namadayamitha amakhulu okucindezela okuphansi.Ubukhulu bama-flanges kanye nobubanzi kanye nenani lama-bolts axhumayo ahlukene ngezingcindezi ezahlukene.
