Uxinzelelo oluphezulu lweFlange

I-flange yoxinzelelo oluphezulu lusetyenziswa ngokubanzi isixhobo sokudibanisa kwindawo yoshishino, esetyenziselwa ukudibanisa iipayipi, iivalve, iiflange kunye nezinye izixhobo. I-flange ephezulu yoxinzelelo yenza uxhulumaniso oluqinileyo ngokuqiniswa kweebholiti kunye namantongomane, ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo kwenkqubo yombhobho.

Ukuhlelwa kwemveliso

Iiflange zoxinzelelo oluphezulu zinokuhlelwa ngokweentlobo ezahlukeneyo ngokusekwe kuyilo kunye nokusetyenziswa kwazo, ezinye zazo eziqhelekileyo:

1. Weld Neck Amadangatye: I-Welding flanges isetyenziswa ngokuqhelekileyo kwindawo yokushisa ephezulu kunye noxinzelelo oluphezulu, kunye noyilo lwabo olude lwentamo lunceda ukusabalalisa uxinzelelo kunye nokuphucula amandla okudibanisa.
2. Iiflange eziyimfama: Iiflange ezingaboniyo zisetyenziselwa ukutywina elinye icala lenkqubo yombhobho kwaye ngokuqhelekileyo zisetyenziselwa ukugcinwa, ukulungiswa, okanye ukutywinwa kwemibhobho.
3. Slip Kwiiflange: Ukutyibilika kwiiflange kulula ukuyifaka kwaye iqhele ukusetyenziselwa uxinzelelo oluphantsi kunye nezicelo ezingabalulekanga, ezifanelekileyo kuqhagamshelo lwexeshana.
4. Umsonto flanges: Iiflange zemisonto zifanelekile kwiindawo ezinoxinzelelo oluphantsi kwaye ziqhele ukusetyenziselwa ukudityaniswa kwemibhobho encinci.
5. I-Socket Weld Flanges: I-Flat welding flanges idibaniswe nge-welding kwaye ifanelekile kubukhulu obuncinci kunye neenkqubo zoxinzelelo oluphantsi.
6. I-Flange Cover: Isetyenziselwa ukukhusela umphezulu wokudibanisa i-flange kwiimpembelelo zangaphandle zendalo kunye nokwandisa ubomi benkonzo ye-flange.

Inqanaba loxinzelelo

Ukulinganiswa koxinzelelo lwe-high-pressure flanges luphawu olubalulekileyo lokuyila kunye nokuvelisa, okubonisa uxinzelelo oluphezulu olunokuthi uxhulumaniso lwe-flange lukwazi ukumelana. Amanqanaba oxinzelelo aqhelekileyo aquka:

I-1.150 pound flanges: ifanelekile kwizicelo eziphantsi koxinzelelo, njengeenkqubo zokubonelela ngamanzi.
I-2.300 pound flanges: ukulinganiswa koxinzelelo oluphakathi, olusetyenziswa ngokuqhelekileyo kwizicelo zoshishino jikelele.
I-3.600 pound flanges: isetyenziswe kwiindawo eziphakamileyo zoxinzelelo ezifana neekhemikhali kunye namashishini epetroleum.
I-4.900 pound flanges: Izicelo zoxinzelelo oluphezulu, ezifana neenkqubo zokuhambisa umphunga.
I-5.1500 pound flanges: Ngezicelo ezikhethekileyo phantsi kweemeko zoxinzelelo oluphezulu kakhulu.
I-6.2500 pound flanges: ekhethekileyo kakhulu kwizihlandlo ezikhethekileyo kunye noxinzelelo oluphezulu.

Umgangatho wamazwe ngamazwe

Ukuveliswa kunye nokusetyenziswa kweeflange ezinoxinzelelo oluphezulu kulawulwa luluhlu lwemigangatho yamazwe ngamazwe ukuqinisekisa umgangatho wabo, ukhuseleko kunye nokuthembeka. Eminye imigangatho eqhelekileyo yamazwe ngamazwe iquka:

I-ASME B16.5: Umgangatho we-flange opapashwe yi-American Society of Mechanical Engineers (ASME) iquka iindidi ezahlukeneyo kunye noxinzelelo lweeflanges.
I-EN 1092: Umgangatho waseYurophu, ochaza uyilo kunye neemfuno zokwenziwa kweeflange zentsimbi.
I-JIS B2220: umgangatho woshishino waseJapan, ukucaciswa kweeflange ezinemisonto.
I-DIN 2633: Umgangatho waseJamani, kubandakanya izibonelelo zemilinganiselo kunye noyilo loqhagamshelo lweflange.
I-GB / T 9112: iMigangatho yeSizwe yaseTshayina, echaza imilinganiselo, isakhiwo, kunye neemfuno zobugcisa beeflange.

Ukulandela imigangatho yamazwe ngamazwe ehambelanayo xa ukhetha kwaye usebenzisa iiflange zoxinzelelo oluphezulu linyathelo elibalulekileyo ekuqinisekiseni ukhuseleko lwenkqubo kunye nokusebenza.

Ngokubanzi, i-high-pressure flanges, njengezinto eziphambili zokudityaniswa kwemibhobho, zidlala indima ebalulekileyo kwiinkalo zoshishino kunye nemveliso. Ngokuqonda iintlobo zabo ezahlukeneyo, amanqanaba oxinzelelo, kunye nemigangatho yamazwe ngamazwe, kunokwenzeka ukuba ukhethe kangcono kwaye usebenzise iiflange eziphezulu zoxinzelelo ezifanelekileyo kwiimfuno ezithile, ngaloo ndlela uqinisekisa ukusebenza kakuhle kunye nokhuseleko lwenkqubo.
