Yini i-flange futhi yiziphi izinhlobo ze-flange?

n iqiniso, igama lei-flangekuyinto eguqukayo. Yaqala ukubekwa phambili ngu-Englishman ogama lakhe lingu-Elchert ngonyaka we-1809. Ngasikhathi sinye, waphakamisa indlela yokuphonsai-flange. Kodwa-ke, ayisetshenziswa kabanzi esikhathini eside ngokuhamba kwesikhathi. Kuze kube ekuqaleni kwekhulu lama-20,i-flangeyasetshenziswa kabanzi emishini ehlukahlukene yemishini kanye nokuxhunywa kwamapayipi.

Yini i-flange?
I-flangeYaziwa nangokuthi i-Flange Convex Disk noma ipuleti le-convex. Ngokuqondene nalabo ababandakanyeka ekufakweni kwemishini noma yobunjiniyela babalingani abancane, kufanele bajwayele kakhului-flange. Yizingxenye ezenziwe nge-disk, ezisetshenziswa ngokuvamile ngababili.Isetshenziswa ikakhulukazi phakathi kwepayipi ne-valve, phakathi kwepayipi kanye nepayipi kanye nepayipi futhi phakathi kwemishini, njll. Yizo izingxenye ezixhumene nomphumela wokubopha uphawu. Kunezicelo eziningi phakathi kwale mishini namapayipi, ngakho-ke izindiza ezimbili zixhunywe ngama-bolts, kanye nezingxenye zokuxhuma ezinomphumela wokuvalwa kwazo zibizwai-flange.

Ngokuvamile, kukhona izimbobo eziyindilinga ku-i-flangeukudlala indima ethile. Isibonelo, lapho usebenzisa ngokuhlanganiswa kwepayipi, kufakwa indandatho yokubopha uphawu phakathi kwalezi ezimbiliAmapuleti we-Flange. Futhi-ke ukuxhumana kuqiniswa ngama-bolts. I-Flange enengcindezi ehlukile inobukhulu obuhlukile kanye nama-bolts ahlukile. Izinto eziphambili ezisetshenziselwa i-flange ziyinsimbi ye-carbon, insimbi engenasici kanye nensimbi, njll.

Ngenxa yendima yayo ebalulekile nokusebenza okuhle okuphelele,i-flangeisetshenziswa kabanzi kumakhemikhali, ama-petrochemical, umlilo kanye nezimboni zokudonsa amanzi.

Njengohlobo lwesixhumi,i-flangeisetshenziswa kabanzi emhlabeni, okudinga ukuhlanganiswa okuhlangene. Isibonelo, kunezinhlelo ezimbili ezijwayelekile zeI-Pipe Flange.

Banguhlelo lwe-european pipeline flange system, okungukuthi uhlelo lwe-european pipeline flange system olumelwe yiJalimane Din (kufaka phakathi iRussia), kanye nohlelo lwePipeline Pipeline olwelwe yi-American Ansi Pipe Flange.

Ngaphezu kwalokho, kukhona uhlelo lwe-ndip pipeline flange system e-Japan ne-Steel Pipe Plange System GB eChina, kepha ubukhulu bangempela bususelwa ohlelweni lwaseYurophu kanye nohlelo lwaseMelika.

Izinhlobo ze-flange
Isakhiwo sei-flangekulula kakhulu. Ihlanganiswe namapuleti aphezulu futhi aphansi we-flange, i-gasket ephakathi kanye nama-bolts amaningana namantongomane.

Kusuka encazelweni yei-flange, Siyakwazi ukuthi kunezinhlobo eziningi zei-flange, futhi ukuhlukaniswa kwalo kudinga ukwehlukaniswa ngezigaba ezahlukahlukene. Ngokwesibonelo, ngokuya ngemodi yokuxhuma, i-flange ingahlukaniswaI-Integrape Flange,I-Flat Welding Flange,I-Butt Welding Flange,I-Sleeve Sleeve Flangeno tHlanga i-flange, okuyi-flange evamile.

I-Flange ebalulekile (uma)ngokuvamile isetshenziswa epayipini ngengcindezi ephezulu. Kuluhlobo lwemodi yokuxhumana ye-Flange, futhi inentamo ende. Imvamisa yakhiwa ngokusakaza okuhlanganisiwe ngesikhathi esisodwa, futhi izinto ezisetshenzisiwe ngokuvamile zensimbi yekhabhoni, insimbi engenasici, njll.

I-Flat Welding Flangeyaziwa nangokuthi i-tower welding flange. Kuqediwe ukushibilika lapho kuxhuma ngomkhumbi noma ngepayipi. Lolu hlobo lwe-welding flange ethambile lunezimpawu zoMkhandlululo olula nentengo ephansi. Isetshenziswa ikakhulukazi epayipini ngengcindezi encane nokudlidliza.

I-Butt Welding Flangeyaziwa nangokuthi i-flange ephakeme yentamo. Umehluko omkhulu phakathi kweButt Welding Flange namanye ama-flanges ukuthi unentamo ephezulu evuthiwe. Ubukhulu bodonga lwentamo oluphezulu oluvelelayo luzofana kancane kancane njengobukhulu nobubanzi bodonga lwepayipi ukuze bubonakaliswe ngokuphakama, okuzokwandisa amandla we-flange. I-Butt Welded Flange isetshenziswa ikakhulukazi ezindaweni ezinezinguquko ezinkulu zemvelo, njengokushisa okuphezulu, ingcindezi ephezulu kanye nepayipi lokushisa eliphansi.

Hlukana ne-flangeyaziwa nangokuthi i-looper flange. Lolu hlobo lwe-flange lusetshenziswa kakhulu kwamanye amapayipi ensimbi angewona ama-forrrous namapayipi angenasici, futhi ukuxhumana kutholwe ukufudumala. Ingajikelezwa. Futhi kulula ukuvumelanisa umgodi we-bolt, ngakho-ke kusetshenziswa kakhulu ekuxhumaneni kwepayipi elikhulu elikhulu futhi kuvame ukuhlanganiswa. Kodwa-ke, ukumelana kwengcindezi kwe-flange evulekile akuphezulu. Ngakho-ke kungasetshenziselwa kuphela ukuxhumana kwepayipi eliphansi lengcindezi.

Kukhona imicu kuipuleti le-flangeyeintambo ethambile, okudinga ukuthi ipayipi langaphakathi liphinde libe nentambo yangaphandle ukuze ibone ukuxhumana. Kuyinto e-welding flange, ngakho-ke inezinzuzo zokufakwa okulula futhi ihlukaniswe ngokuqhathaniswa nenye i-welding flange. Emvelweni yokushisa okuphezulu noma okuphansi, i-filealed flange ayilungele ukusetshenziswa, ngoba intambo kulula ukuyivuza ngemuva kokunwetshwa kwe-thermal kanye nokukhokhwa okubandayo.
