Iiflange ezinobubanzi obukhulu lunye uhlobo lweeflange, ezisetyenziswa kakhulu kwaye zikhuthazwa kwishishini lomatshini kwaye zamkelwe kakuhle kwaye zithandwa ngabasebenzisi. Iiflange ezinobubanzi obukhulu zisetyenziswa ngokubanzi, kwaye ububanzi bokusetyenziswa bunqunywe ngokweempawu ezahlukeneyo. Ziye zisetyenziswe kakhulu kwiimeko apho iimeko eziphakathi zincinci, ezifana ne-low-pressure non-purified compressed air and low-pressure circulating water. Inzuzo yayo kukuba ixabiso lincinci. Iiflange eziqengqelekayo zifanelekile ukudityaniswa kwemibhobho yentsimbi kunye noxinzelelo oluncinci olungadlulanga kwi-2.5MPa. Umphezulu wokutywina we-flange eqengqelekayo unokwenziwa ube luhlobo olugudileyo. Umthamo wokusetyenziswa kweeflange ezigudileyo kunye nezinye iindidi ezimbini zeeflange eziqengqelekayo nazo ziqhelekile ukusetyenziswa.

Iiflange ezinobubanzi obukhulu zinqunyulwa zibe yimichilo kunye neplate ephakathi kwaye zigqitywe kwisangqa. Emva koko inkqubo imigca yamanzi, imingxuma yebholiti, njl. Oku ngokuqhelekileyo i-flange enkulu, enokuba yi-7 yeemitha. Izinto eziluhlaza yipleyiti ephakathi kunye noxinano oluhle. Iiflange ezinobubanzi obukhulu zenziwe nge-carbon steel, insimbi engenasici, insimbi ye-alloy, njl.

Iimpawu zemveliso kunye nokusetyenziswa kwe-flanges enkulu-diameter zibonakaliswa ikakhulu kwiindawo ezingentla. Ukuba sonke sisebenza kwaye sisebenzisa iiflange ezinobubanzi obukhulu, sonke kufuneka siziqonde ezi mpawu banazo.

Kukho iintlobo ezintathu zeendawo zokutywina ze-flange ezinobubanzi obukhulu: iindawo zokutywina ezisicaba, ezifanelekileyo kwizihlandlo ezinoxinzelelo oluphantsi kunye neendaba ezingenayo inetyhefu; iindawo zokutywina eziconcave kunye neconvex, ezifanelekileyo ngamaxesha anoxinzelelo oluphezulu kancinci; ulwimi kunye nomphezulu wokutywina, olungele ukutsha, ukuqhuma, imidiya eyityhefu kunye noxinzelelo oluphezulu. Iyintoni inkqubo yomgangatho weeflange ezinobubanzi obukhulu?

Inkqubo yomgangatho weeflange ezinobubanzi obukhulu ngolu hlobo lulandelayo:
Iiflange ezinobubanzi obukhulu eziveliswa ngokusebenzisa iinkqubo ezahlukeneyo zineenzuzo kunye nokungona kwazo, kodwa oku akunjalo. Kwiiflange ezinobubanzi obukhulu ezenziwe ngamacwecwe aphakathi, unyango lwendawo edibeneyo lubaluleke kakhulu. Ukuba esi sikhundla asithungelwanga kakuhle, ukuvuza kuya kwenzeka. Kwiiflange ezinobubanzi obukhulu obubunjiweyo, kuya kubakho umaleko wesikhumba kwi-flange egqityiweyo emva kokuba iphumile. Ukuba umngxuma we-bolt ubethelwe kwindawo yoluhlu lwesikhumba, ukuvuza kwamanzi kuya kwenzeka xa uxinzelelo lusetyenziswa.
