Ukubaluleka kweSawn kunye nombhobho odityanisiweyo kwiZibonelelo zale mihla, kumbindi weCangzhou, kwiPhondo laseHebei, kuhleli ilitye lentsimbi elililitye lembombo kwishishini lombhobho wentsimbi ukusukela ekusekweni kwayo ngo-1993. Phakathi kweemveliso zayo ezininzi kukho imibhobho esarha kunye ne-welded, icandelo elibalulekileyo leziseko zophuhliso lwale mihla, ngakumbi kuthutho lwamanzi aphantsi komhlaba.
Ngaphantsi komhlabaSaw Welded Umbhobhozibalulekile ekuthuthweni kwamanzi ngokufanelekileyo nangokuthembekileyo kwiindawo ngeendawo. Ziyintsika yeziseko ezingundoqo zethu zale mihla, ziqinisekisa ukuba amanzi acocekileyo afikelela ezindlini, kumashishini nakwiindawo zolimo. Ukukhethwa kwezinto eziphathekayo kule mibhobho kubalulekile, njengoko kufuneka baxhathise uxinzelelo lwendalo ephantsi komhlaba ngelixa begcina ingqibelelo yabo yexesha elide. Olunye ukhetho oludumileyo kwezi zicelo ngumbhobho wentsimbi wekhabhoni odityaniswe ngokuvunguza, owaziwa ngamandla kunye nokuqina kwawo.
Umbhobho wentsimbi we-S235 JR ojikelezayo kunye ne-X70 SSAW (i-Spiral Submerged Arc Welded) umbhobho womgca ziimveliso ezimbini eziqhelekileyo ezisetyenziswa ngokubanzi kwiinkqubo zemibhobho yamanzi angaphantsi komhlaba. Umbhobho we-S235 JR uthathwa kakhulu ngenxa yeempawu zayo ezibalaseleyo zoomatshini, okwenza ukuba ulungele usetyenziso oluhlukeneyo, kubandakanywa nokuthuthwa kwamanzi. Ikhono layo lokuchasa ukuguqulwa phantsi koxinzelelo liqinisekisa ukuba lihlangabezana neemfuno zezibonelelo eziphantsi komhlaba.
Namhlanje, ngenxa yenkqubo ekhawulezileyo yokwakhiwa kweedolophu, inkqubo ethembekileyo yokuhanjiswa kwamanzi angaphantsi komhlaba iye yaba ngundoqo ekuqinisekiseni ukuphila kwabantu. Njengeshishini eliphambili kushishino lokwenziwa kwePipe yentsimbi, iplanti yentsimbi ethile kwisiXeko saseCangzhou, kwiPhondo laseHebei, ibonelele ngomgangatho ophezulu wemibhobho yeSaw Welded kwiziseko ezingundoqo zehlabathi ukususela ekusekweni kwayo ngo-1993.
1. Amandla aphezulu kunye nokumelana nokubola kuqinisekisa ukhuseleko lokuhamba kwamanzi ixesha elide. Umbhobho ojikelezayo we-S235 JR: Ibonisa ukuxhathisa okugqwesileyo kwi-deformation deformation kwaye ifanele imimandla enzima yejoloji, iqinisekisa ukusebenza okuzinzileyo kwexesha elide lombhobho. Umbhobho we-X70 SSAW: Yenziwe ngentsimbi ephezulu kunye neteknoloji ye-welding ye-spiral, ayinyanzeli uxinzelelo kunye ne-corrosion-resistant, ilungele ukuhanjiswa kwamanzi okude kunye neendawo ezinzima.
2. Ubuchwephesha obuphezulu obudityaniswe nolawulo olungqongqo lwekhwalithi lwenza inkqubo yombhobho ezinzileyo. Lo mzi-mveliso wamkela itekhnoloji ye-spiral submerged arc welding (SAW) ukuphumeza imveliso esebenzayo yobubanzi obukhulu, iityhubhu ezinodonga olucekethekileyo, ukwandisa ukusetyenziswa kwezinto ngelixa uqinisekisa amandla. Ngentsebenziswano neqela lobuchwephesha labantu abangama-680 kunye nomgca wemveliso yanamhlanje oxabisa i-yuan yezigidi ezingama-680, siqinisekisa ukuba yonke ipayipi yentsimbi idibana nemigangatho yamazwe ngamazwe, inegalelo kuphuhliso lweziseko eziluhlaza. Ngokuphuculwa kweemfuno zolawulo lobutyebi bamanzi emhlabeni jikelele, imibhobho edityanisiweyo ye-sawld ye-Cangzhou Steel Plant iya kuqhubeka nokubonelela ngezisombululo ezihlala ixesha elide kunye neendleko eziphantsi kumasipala, ukuthutha amanzi ezolimo kunye nezoshishino, ukukhuthaza ukwakhiwa kweziseko zokulondoloza amanzi ezizinzileyo.
imibhobho esarha kunye newelded eveliswe yiCangzhou Steel Mills yinxalenye ebalulekileyo yeenkqubo zamanzi aphantsi komhlaba. I-S235 JR kunye ne-X70 spiral imibhobho edityanisiweyo ye-arc edityanisiweyo, eneempawu ezibalaseleyo zoomatshini kunye nokuchasana nezinto ezisingqongileyo, zibalulekile ekuqinisekiseni ukuthuthwa kwamanzi okufanelekileyo. Ukujonga phambili, ukubaluleka kwezi mveliso kuya kuqhubeka nokukhula, kuqaqambisa imfuno yoshishino lombhobho wentsimbi kwimveliso ekumgangatho ophezulu kunye nezisombululo ezintsha.
