Inkqubo yokwenziwa kwemibhobho ye-SMLS engenamthungo
Ukukhethwa kweMathiriyeli ekrwada:Umgangatho ophezulu wekhabhoni yentsimbi ukhethwa njengezinto eziluhlaza kwimibhobho yentsimbi yekhabhoni engenamthungo. Umxholo wekhabhoni kwintsimbi yinto ephambili ekunqumeni iimpawu zayo kunye nokufaneleka kwezicelo ezahlukeneyo.
Ukufudumeza nokugqobhoza:Impahla ekrwada ifudunyezwa kubushushu obuphezulu kwaye emva koko igqojozwe ukwenza iqokobhe elinomngxuma. Le nkqubo ibalulekile ekudaleni ubume bokuqala bombhobho kwaye ngokuqhelekileyo iphunyezwa ngeendlela ezinjengokugqobhoza okujikelezayo, ukukhutshwa, okanye ezinye iindlela ezikhethekileyo.
Ukuqengqeleka kunye nobungakanani:Iqokobhe elihlatyiweyo liqhuba iinkqubo zokuqengqeleka kunye nokulinganisa ukunciphisa ububanzi kunye nobukhulu bodonga ukuya kwimilinganiselo efunekayo. Oku kuphunyezwa kusetyenziswa uthotho lwezingqusho eziqengqelekayo kunye nemilinganiselo yokusila ukufikelela kwimilo efunekayo kunye nemilinganiselo.
Unyango loBubushushu:Umbhobho we-carbon steel ongenamthungo uphantsi kweenkqubo zonyango lobushushu ezifana nokucima, ukunyanzeliswa, okanye ukucima kunye nokufudumala ukunyusa iimpawu zayo zomatshini kunye nokususa naluphi na uxinzelelo olushiyekileyo. Unyango lokushisa lukwanceda ekufezekiseni i-microstructure efunwayo kunye neempawu ze-carbon steel.
Uvavanyo kunye noHlolo:Kuyo yonke inkqubo yokuvelisa, umbhobho wekhabhoni ongenamthungo uhamba ngeendlela ezahlukeneyo zokuvavanya ezingonakalisi kunye nezonakalisayo zokuqinisekisa ukuba ihlangabezana nemigangatho yomgangatho ofunekayo. Oku kunokubandakanya uvavanyo lwe-ultrasonic, uvavanyo lwe-hydrostatic, uvavanyo lwangoku lwe-eddy, kunye nokuhlolwa okubonakalayo.
Ukugqiba kunye noKwaleka:Emva kokuba umbhobho ongenamthungo udibana neenkcukacha ezifunekayo, uqhuba iinkqubo zokugqiba ezifana nokulungelelanisa, ukusika, kunye nokuphela kokugqiba. Ukongezelela, umbhobho unokufakwa ngezinto zokukhusela ezifana ne-varnish, ipeyinti, okanye i-galvanizing ukunyusa ukuxhathisa ukubola, ngakumbi kwimeko ye-carbon steel.
Uhlolo lokugqibela kunye nokuPakisha:Umbhobho ogqityiweyo wensimbi ongenamthungo uhlolwa okokugqibela ukuqinisekisa ukuba uhlangabezana nayo yonke imigangatho yomgangatho kunye neemfuno zabathengi. Emva koko ipakishwe ngononophelo kwaye ilungiselelwe ukuthunyelwa kumthengi.

Uvavanyo lweHydrostatic
umbhobho ongenamthungo uya kumelana novavanyo lwe-hydrostatic ngaphandle kokuvuza ngomthungo we-weld okanye umzimba wombhobho.
