Isikhokelo esibanzi seBanga lesi-2 se-Steel Stoe
Funda malunga ne-A252 yentsimbi ye-2 yentsimbi:
I-A252 iBakala 2 lentsimbingumbhobho we-carbon ye-carbon yenzelwe ukusetyenziswa kwizicelo zoxinzelelo kunye nezicelo zesakhiwo. Inziwa ngokungqinelana ne-ASTM (uMbutho waseMelika wovavanyo kunye nezixhobo) kwimigangatho, iqinisekisa imigangatho ekumgangatho ophezulu kunye nokuchaneka komgangatho. Uchonge lweBanga 2 lubonisa ukuba umbhobho wentsimbi wenzelwe kusetyenziswa iindlela ze-Arc ezinamachaphaza okanye ezingenamthungo.
Ukubaluleka kokufumana i-arc ye-arc kabini
I-arc engaphantsi komhlaba, ekwabizwa ngokuba yi-DSAW, yinkqubo yokukhethekileyo yeWolding esetyenziselwa ukujoyina icandelo le-A252 yentsimbi ye-2. I-DSAW ibonelela ngeenzuzo ezininzi kwezinye iindlela ze-welding, kubandakanya ukuthembeka kwexabiso elifanelekileyo, isantya esiphezulu seWolding, ukugqwetha okuncinci, kunye nolawulo oluhle kakhulu lokufaka. Iqinisekisa iqhina elinamandla phakathi kwemibhobho, ibenza bangathathi ntweni ukuvuza, ukubongoza kunye nolwakhiwo.

Kutheni usebenzisa umbhobho wentsimbi ye-A252 kwiBanga le-2 yeeprojekthi ze-Swer?
I-1. Ukunqunyulwa okugqwesileyo: I-A252 Ibanga lesi-2 iBakala 2 linamandla amakhulu e-thensile, owenza ukuba ixhathise uxinzelelo lwangaphandle kunye noxinzelelo. Ukuqina kwabo kuqinisekisa ubomi obude beenkonzo, ukunciphisa isidingo sokutshintsha okanye ukulungiswa.
2. Ukuxhathisa i-Interrosion: IBakala lesi-2 lentsimbi le-2 yenzelwe ukumelana neemeko eziphantsi komhlaba, kubandakanya ukuvezwa kokuntywila, iikhemikhali kunye nokufuma, ngaphandle kokuthuka okanye ukungcola. Eli nqaku lonyusa ubomi benkonzo yemibhobho yogutyulo.
I-3. Iindleko zexabiso: IBakala lesi-2 lentsimbi inika isisombululo esinexabiso lokwakha umbhobho wokuthengisa. Iimfuno zabo zolondolozo eziphantsi kunye nobomi obude zinokugcina oomasipala kunye neekhontrakthi zeprojekthi ukonga ngokuhamba kwexesha.
Ukusetyenziswa kwe-A252 iBanga le-2 yentsimbi kwiNkulumbu-mbumbulo
I-A252 yentsimbi ye-2 ye-2 isetyenziswe ngokubanzi kwiiprojekthi zezibonelelo zothumo lwe-Sumhar, kubandakanya:
I-1. Inkqubo yokuThengisa yaseMabureji: IBakala 2 lentsimbi isetyenziswe ngokubanzi ekwakhiweni kwemibhobho yobuso bukaMasipala yokuhambisa amanzi amdaka kwiindawo zokuhlala kunye neendawo zorhwebo.
I-2. Inkqubo yokuHamba ye-Sewe ye-Sewe: I-Syries Bunds ifuna iinkqubo zogutyulo lwamanzi ukuhambisa amanzi amdaka aphuma kwiiyunithi zokuvelisa kunye nezinye izixhobo. I-A252 yentsimbi ye-2 yentsimbi ibonelela ngamandla ayimfuneko kunye nokuqina kolu hlobo lwesicelo semizi-mveliso.
Ukuququmbela:
Xa kuziwaUmgca wokuntywilaUkwakhiwa, i-A252 iBanga le-2 yentsimbi edibeneyo neTekhnoloji ye-DSAW ibonelela ngamandla angenakuthelekiswa nanto, ukuqina kunye nokusebenza ngokubanzi. Ukunganyangeki kwawo okhethekileyo, amandla aphezulu obugorha kunye nokusebenza kwexabiso kwenza ukuba ilungele iintlobo ezahlukeneyo zeziseko zoncedo. Ngokamkela ezi zixhobo ziphambili kunye neendlela ze-welding, izixeko zinokunyusa kakhulu iinkqubo zawo zokuhambisa iimpahla, zinciphise iindleko zokulondolozwa kwaye ziqinisekise ukuba umntu ococekileyo, osemngciphekweni wonke umntu.
