Iyini iFlange Futhi Yiziphi Izinhlobo zeFlange?

eqinisweni, igama likai-flangekuyi-translation. Yaqala ukwethulwa yiNgisi okuthiwa u-Elchert ngo-1809. Ngesikhathi esifanayo, waphakamisa indlela yokukhiphai-flangeNokho, ayizange isetshenziswe kabanzi esikhathini eside kamuva. Kuze kube sekuqaleni kwekhulu lama-20,i-flangeyayisetshenziswa kabanzi emishinini eyahlukahlukene yomshini kanye nokuxhumeka kwamapayipi.

Kuyini i-flange?
I-Flangeyaziwa nangokuthi idiski ye-flange convex noma ipuleti le-convex. Ngokuqondene nalabo ababandakanyeka ekufakweni kwemishini noma kobunjiniyela kwabalingani abancane, kufanele bajwayelane kakhulu ne-i-flange. Kuyizingxenye ezimise okwediski, ngokuvamile ezisetshenziswa ngamabili. Isetshenziswa kakhulu phakathi kwepayipi nevalvu, phakathi kwepayipi nepayipi naphakathi kwepayipi nemishini, njll. Yizingxenye ezixhumanisa ngomphumela wokuvala. Kunezinhlelo zokusebenza eziningi phakathi kwale mishini namapayipi, ngakho-ke lezi zindiza ezimbili zixhunywe ngamabhawodi, kanti izingxenye ezixhumanisayo ezinomphumela wokuvala zibizwa ngokuthii-flange.

Ngokuvamile, kunezimbobo eziyindilingai-flangeukudlala indima engaguquki. Isibonelo, uma usebenzisa endaweni yokuxhuma ipayipi, indandatho yokuvala ifakwa phakathi kwalezi ezimbiliamapuleti e-flangeBese uxhumano luqiniswa ngamabholithi. I-flange enengcindezi ehlukile inobukhulu obuhlukile namabholithi ahlukene. Izinto eziyinhloko ezisetshenziselwa i-flange yi-carbon steel, insimbi engagqwali kanye ne-alloy steel, njll.

Ngenxa yendima yayo ebalulekile kanye nokusebenza okuhle okuphelele,i-flangeisetshenziswa kabanzi embonini yamakhemikhali, i-petrochemical, umlilo kanye ne-drainage.

Njengohlobo lwesixhumi,i-flangeisetshenziswa kabanzi emhlabeni, okudinga indinganiso ehlangene. Isibonelo, kunezinhlelo ezimbili ezijwayelekile zeiphayiphi yeflange.

Ziyisistimu yeflange yamapayipi aseYurophu, okungukuthi uhlelo lweflange yamapayipi aseYurophu olumelwe yi-DIN yaseJalimane (kufaka phakathi iRussia), kanye nohlelo lweflange yamapayipi aseMelika olumelwe yiflange yamapayipi aseMelika.

Ngaphezu kwalokho, kunesistimu ye-JIS pipeline flange eJapan kanye nesistimu ye-flange yepayipi lensimbi i-GB eShayina, kodwa ubukhulu obuyinhloko busekelwe ohlelweni lwaseYurophu kanye nohlelo lwaseMelika.

Izinhlobo ze-flange
Isakhiwo se-i-flangeilula kakhulu. Yakhiwe ngamapuleti e-flange aphezulu naphansi, i-gasket ephakathi kanye nama-bolts amaningana namantongomane.

Kusukela encazelweni ye-i-flange, singazi ukuthi kunezinhlobo eziningii-flange, futhi ukuhlukaniswa kwayo kudinga ukuhlukaniswa ngobukhulu obuhlukene. Isibonelo, ngokwemodi yokuxhuma, i-flange ingahlukaniswai-flange ehlanganisiwe,i-flange yokushisela eyisicaba,i-flange yokushisela izinqe,i-flange yemikhono ekhululekilekanye no-ti-flange enezintambo, okuyi-flange evamile futhi.

I-Integral flange (UMA)ngokuvamile isetshenziswa epayipini elinomfutho ophezulu. Luhlobo lwemodi yokuxhuma i-flange, futhi lunentamo ende. Ngokuvamile lwakhiwa ngokukhipha i-integral okuhlanganisiwe okukodwa, futhi izinto ezisetshenziswayo ngokuvamile ziyinsimbi yekhabhoni, insimbi engagqwali, njll.

I-flange yokushisela eyisicabayaziwa nangokuthi i-tower welding flange. Iqedwa ngokushisela uma ixhunywa nomkhumbi noma ipayipi. Lolu hlobo lwe-flange yokushisela eyisicaba lunezici zokuhlanganiswa okulula kanye nentengo ephansi. Isetshenziswa kakhulu epayipini ngokucindezela okuncane nokudlidliza.

I-flange yokushisela izinqeyaziwa nangokuthi i-flange yentamo ephezulu. Umehluko omkhulu phakathi kwe-flange yokuwelda ye-butt kanye nezinye i-flange ukuthi inentamo ephezulu ephumayo. Ubukhulu bodonga lwentamo ephezulu ephumayo buzofana kancane kancane nobukhulu nobubanzi bodonga lwepayipi oluzohlanganiswa nokuphakama, okuzokwandisa amandla e-flange. I-flange ehlanganisiwe ye-butt isetshenziswa kakhulu ezindaweni ezinezinguquko ezinkulu zemvelo, njengokushisa okuphezulu, ukucindezela okuphezulu kanye nepayipi lokushisa eliphansi.

I-flange ekhululekileIyaziwa nangokuthi i-looper flange. Lolu hlobo lwe-flange lusetshenziswa kakhulu kwamanye amapayipi ensimbi angenawo ugesi kanye nensimbi engagqwali, futhi uxhumano lutholakala ngokushisela. Lungajikeleziswa. Futhi kulula ukuqondisa imbobo yebholidi, ngakho-ke lusetshenziswa kakhulu ekuxhumeni kwepayipi elikhulu futhi ngokuvamile kudingeka lihlukaniswe. Kodwa-ke, ukumelana kwengcindezi ye-flange ekhululekile akuphakeme. Ngakho-ke ingasetshenziswa kuphela ekuxhumeni kwepayipi elinengcindezi ephansi.

Kukhona imicu ku-ipuleti le-flangekwei-flange enezintambo, okudinga ukuthi ipayipi langaphakathi libe nentambo yangaphandle ukuze kufezwe uxhumano. Liyi-flange engashiseli, ngakho-ke linezinzuzo zokufakwa nokuhlukaniswa okulula uma kuqhathaniswa nezinye i-flange zokushisela. Endaweni yokushisa okuphezulu noma okuphansi, i-flange enentambo ayifanele ukusetshenziswa, ngoba intambo kulula ukuyivuza ngemva kokukhula kokushisa kanye nokufinyela okubandayo.
