Integral Flange

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. Ukuxhumeka kwe-Flange kuwukuxhumana okungalahleka. Ngokusho kwezingxenye ezixhunyiwe, ingahlukaniswa ibe yi-container flange kanye ne-pipe flange. Ngokusho kohlobo lwesakhiwo, kukhona ama-flanges abalulekile, ama-flange avulekile nama-flanges anezintambo. Ama-flange ajwayelekile ahlanganisa ama-flange welding flat kanye nama-flange welding we-butt. Amaflange ane-flat-welded 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 ephezulu yokucindezela kanye nendawo yokuvala incane kakhulu (ukuxhumana komugqa), futhi ukuqedwa 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.
