Iyini I-Flange Futhi Yiziphi Izinhlobo Ze-Flange?

n eqinisweni, igama likai-flangeiwukuguqulwa kwamaletha.Yaqala ukubekwa phambili iNgisi okuthiwa u-Elchert ngo-1809. Ngesikhathi esifanayo, yahlongoza indlela yokulingisai-flange.Nokho, ayizange isetshenziswe kabanzi esikhathini eside kamuva.Kuze kube sekuqaleni kwekhulu lama-20,i-flangeyayisetshenziswa kabanzi emishinini ehlukahlukene kanye nokuxhunywa kwamapayipi.

Iyini i-flange?
I-Flangeyaziwa nangokuthi i-flange convex disk noma ipuleti le-convex.Ngokuqondene nalabo abenza ukufakwa kwemishini noma kobunjiniyela kozakwethu abancane, kufanele babajwayele kakhului-flange.Iyingxenye emise okwediski, ngokuvamile esetshenziswa ngababili.Isetshenziswa kakhulu phakathi kwepayipi nevalvu, phakathi kwepayipi nepayipi naphakathi kwepayipi nezinto zokusebenza, njll. Izingxenye ezixhumeka ngokuvala uphawu.Kunezinhlelo zokusebenza eziningi phakathi kwalezi mishini namapayipi, ngakho-ke izindiza ezimbili zixhunywe ngamabhowuthi, futhi izingxenye zokuxhuma ezinomphumela wokuvala zibizwa ngokuthi.i-flange.

Ngokuvamile, kunezimbobo eziyindilingai-flangeukudlala indima engashintshi.Isibonelo, uma usebenzisa ekuhlanganyeleni kwepayipi, indandatho yokuvala yengezwa phakathi kokubiliamapuleti flange.Bese-ke ukuxhumana kuqiniswa ngamabhawodi.I-flange enengcindezi ehlukene inogqinsi oluhlukene namabhawodi ahlukene.Izinto eziyinhloko ezisetshenziselwa i-flange yi-carbon steel, insimbi engagqwali ne-alloy steel, njll.

Ngenxa yendima yayo ebalulekile kanye nokusebenza okuhle okubanzi,i-flangeisetshenziswa kakhulu ezimbonini zamakhemikhali, ze-petrochemical, zomlilo kanye nezikhipha amanzi.

Njengohlobo lwesixhumi,i-flangeisetshenziswa kabanzi emhlabeni, okudinga izinga elihlangene.Isibonelo, kunezinhlelo ezimbili ezijwayelekile zeipayipi flange.

Ziwuhlelo lwe-European flange yamapayipi, okungukuthi i-European pipeline flange system emelwe yi-German DIN (kuhlanganise ne-Russia), kanye nohlelo lwe-American pipeline flange olumelwe i-American ANSI ipayipi flange.

Ngaphezu kwalokho, kukhona uhlelo lwe-JIS lwamapayipi e-flange e-Japan kanye ne-steel pipe flange system GB e-China, kodwa ubukhulu obuyinhloko busekelwe ohlelweni lwaseYurophu kanye nohlelo lwaseMelika.

Izinhlobo ze-flange
Isakhiwo se-i-flangeilula uma kuqhathaniswa.Yakhiwa amapuleti e-flange aphezulu naphansi, i-gasket ephakathi namabhawodi amaningana namantongomane.

Kusukela encazelweni yei-flange, singakwazi ukuthi kunezinhlobo eziningii-flange, futhi ukuhlukaniswa kwayo kudinga ukuhlukaniswa kubukhulu obuhlukahlukene.Isibonelo, ngokuya ngemodi yokuxhuma, i-flange ingahlukaniswa ibeflange ebalulekile,flat Welding flange,i-butt welding flange,i-sleeve flange evulekilekanye ti-flange ehlutshiwe, okuyi-flange evamile.

I-Integral flange (IF)ngokuvamile isetshenziswa epayipini elinengcindezi ephezulu.Iwuhlobo lwemodi yokuxhumeka kwe-flange, futhi inentamo ende.Ivamise ukwakhiwa ngokubunjwa okuhlanganisiwe kwesikhathi esisodwa, futhi izinto ezisetshenziswayo ngokuvamile ziyi-carbon steel, insimbi engagqwali, njll.

I-flat welding flangeyaziwa nangokuthi i-tower welding flange.Igcwaliswa ngokushisela lapho ixhunywa ngomkhumbi noma ngepayipi.Lolu hlobo lwe-flange welding welding lunezici zokuhlangana okulula kanye nentengo ephansi.Isetshenziswa kakhulu epayipini elinengcindezi encane kanye nokudlidliza.

I-butt welding flangeyaziwa nangokuthi i-high neck flange.Umehluko omkhulu phakathi kwe-butt welding flange namanye ama-flange ukuthi inentamo ephakeme ephumile.Ubukhulu bodonga lwentamo ephakeme ephumayo kancane kancane buzofana nobukhulu kanye nobubanzi bodonga lwamapayipi okumele luhlanganiswe nokuphakama, okuzokwandisa amandla e-flange.I-butt welded flange isetshenziswa kakhulu ezindaweni ezinezinguquko ezinkulu zemvelo, njengezinga lokushisa eliphezulu, umfutho ophezulu kanye nepayipi lokushisa eliphansi.

I-flange evulekileyaziwa nangokuthi i-looper flange.Lolu hlobo lwe-flange lusetshenziswa kakhulu kwamanye amapayipi ensimbi angeyona ayoni kanye nensimbi engagqwali, futhi uxhumano lwenziwa ngokushisela.Ingaphendukiswa.Futhi kulula ukuvumelanisa imbobo yebhawodi, ngakho-ke isetshenziswa kakhulu ekuxhumekeni kwepayipi elikhulu lobubanzi futhi ngokuvamile lidinga ukuhlakazwa.Kodwa-ke, ukumelana nokucindezela kwe-flange okuxekethile akuphakeme.Ngakho-ke ingasetshenziswa kuphela ekuxhumekeni kwepayipi elinomfutho ophansi.

Kukhona izintambo ku-ipuleti le-flangekwei-flange enentambo, okudinga ukuthi ipayipi langaphakathi libe nentambo yangaphandle ukuze ibone ukuxhumana.I-non welding flange, ngakho-ke inezinzuzo zokufakwa okulula nokuhlakazeka uma kuqhathaniswa namanye ama-flange wokushisela.Emvelweni wokushisa okuphezulu noma okuphansi, i-flange ene-threaded ayifanele ukusetshenziswa, ngoba intambo kulula ukuvuza ngemva kokunwetshwa okushisayo nokufinyela okubandayo.
