Ngaphantsi komgangatho we-SANS 1123, kukho iindidi ezininzi zokutyibilika kwiiflange, ukuwelda iiflange zentamo,iiflange ezihlangeneyo,iiflange ezingaboniyokwayeiiflange ezinemisonto.
Ngokwemigangatho yobungakanani, i-SANS 1123 yahlukile kwimigangatho eqhelekileyo yaseMelika, yaseJapan kunye neYurophu. Esikhundleni seKlasi, i-PN kunye ne-K, i-SANS 1123 ithatha ukumelwa okukhethekileyo: eyahlukileyo, 600/2, 1000/2, 1600/2, 250/2, 4000/2, iflange eyimfama yi 600/8, 1000/8, 1600/8, 2500/8, 4000/8, iflange enemisonto yi600/ I-4, i-1000/4, i-1600/4, i-2500/4, i-4000/4, i-flange ekhululekile ingenziwa ngokwezifiso.
I-SANS 1123 flange ikufutshane ne-European flange ephawulwe nge-PN, kwaye izinga loxinzelelo lwayo lusuka kwi-250 kPa ukuya kwi-4000 kPa, eguqulelwe kumlinganiselo woxinzelelo ophawulwe nge-PN, oko kukuthi i-PN 2.5 ukuya kwi-PN 40, kodwa ubushushu bayo obusebenzayo bu - I-10 ℃ ukuya ku-200 ℃, kwaye uluhlu olusebenzayo lobushushu luncinci. Emva kokuqinisekiswa, kwafunyaniswa ukuba, xa kuthelekiswa ne-BS EN 1092-1 flange, phantsi kobukhulu obufanayo kunye nodidi oluhambelana noxinzelelo, nangona ezinye iiflange ezinkulu ze-SANS 1123 flange zincinci, i-flange yangaphandle ububanzi, i-bolt hole iziko. isangqa sesangqa, iiseti ze-fastener kunye neenkcukacha zomsonto, ezimisela ukuba iiflange ezimbini zinokulungiswa zizibophelelo, ngokusisiseko zilingana nobukhulu boqhagamshelo lweflange, Ngoko ke, i-SANS 1123 flange ngokusisiseko ihlangabezana neemfuno zamabakala ahlukeneyo emathiriyeli yombhobho kule projekthi.
Ngenxa yokuba inqanaba lobuchwephesha bemveliso yemibhobho yentsimbi yaseMzantsi Afrika isemva kwamazwe aphuhlileyo aseYurophu nase-United States, izalathisi zobugcisa zemibhobho yentsimbi eveliswe ngokwemigangatho yaseMzantsi Afrika ziphantsi kwaye noxinzelelo lokuthwala umthamo ulinganiselwe, intsimbi yaseMzantsi Afrika. umgangatho wombhobho wale projekthi usetyenziselwa kuphela imibhobho yentsimbi yekhabhoni enobushushu obuphantsi kunye noxinzelelo oluphantsi, kunye nemibhobho yentsimbi yekhabhoni enoxinzelelo loyilo ＞ 2.5 MPa okanye ubushushu boyilo ＞ 100 ℃ kunye nayo yonke imibhobho yensimbi engenasici ithatha imigangatho yaseMelika. Ukwakheka kweekhemikhali kunye nesalathiso samandla sezinto zombhobho wensimbi kwimigangatho yemibhobho yentsimbi yaseMzantsi Afrika kunye nemigangatho yemibhobho yensimbi yaseMelika inomahluko othile, kwaye eminye imibhobho yentsimbi inobubanzi obuhlukeneyo bangaphandle (jonga iThebhile 1, njenge-DN65). Nangona ingxaki yomahluko ekubunjweni kwezinto eziphathekayo zombhobho wensimbi kwizinto zombini eziphelweni ze-weld zingasombululwa ngokukhethwa kweentonga ze-welding kunye nokuphuculwa kwenkqubo ye-welding, kunye nengxaki yokwahlukana kwi-diameter yangaphandle ye-welding. umbhobho wentsimbi kuzo zozibini iziphelo ze-butt weld ungasonjululwa ngokucheba okuguquguqukayo, ngaphandle kwamathandabuzo oku kuzisa ubunzima obuninzi kulwakhiwo lombhobho kwaye akuhambisani nesiqinisekiso somgangatho wolwakhiwo. Uqhagamshelo lokutywina lunokuphunyezwa ngentsebenziswano yeflange, igasket kunye nefastener. I-gasket iyahlula ama-flange kuzo zombini iziphelo, kwaye i-fastener ayifuni izinto ezifanayo zeeflange kuzo zombini iziphelo. Ngoko ke, umahluko phakathi kokubunjwa kwezinto eziphathekayo kunye nobubanzi bangaphandle beepayipi zensimbi kuzo zombini iziphelo zingasombululwa. Emva koko, ukudityaniswa kwemibhobho yensimbi enemigangatho eyahlukeneyo ngokuqhelekileyo kwenzeka kwindawo apho ibakala lezinto zombhobho litshintsha. Amalungu anjalo awaninzi, kwaye ukusetyenziswa kweeflange akuyi kongeza iindleko ezininzi kwiprojekthi.
