Ukubaluleka kwePipe ezisikiweyo nezihlanganisiweyo kwiZiseko zoPhuhliso zanamhlanje, entliziyweni yeCangzhou, kwiPhondo laseHebei, kukho umzi-mveliso wentsimbi obe sisiseko soshishino lwemibhobho yentsimbi ukusukela oko yasekwa ngo-1993. Le nkampani igubungela iimitha zesikwere ezingama-350,000, inempahla iyonke eyi-680 yezigidi zeerandi, kwaye iqeshe abasebenzi abazinikeleyo abangama-680. Phakathi kweemveliso zayo ezininzi kukho imibhobho esikiweyo nehlanganisiweyo, into ebalulekileyo kwiziseko zophuhliso zanamhlanje, ngakumbi ekuthuthweni kwamanzi angaphantsi komhlaba.
Ngaphantsi komhlabaUmbhobho oWeldingwe ngoSawzibalulekile ekuthuthweni kwamanzi ngokufanelekileyo nangokuthembekileyo kwiindawo ezahlukeneyo. Zenza umqolo weziseko zethu zanamhlanje, ziqinisekisa ukuba amanzi acocekileyo afikelela emakhaya, kumashishini nakwiindawo zezolimo. Ukukhetha izinto ezisetyenziswa kwezi mibhobho kubalulekile, njengoko kufuneka zimelane noxinzelelo lwendalo engaphantsi komhlaba ngelixa zigcina ukuthembeka kwazo ixesha elide. Enye yezona ndlela zidumileyo zokusetyenziswa kwezi zicelo yipayipi yentsimbi yekhabhoni ewelded nge-spirally, eyaziwa ngamandla ayo nokuqina kwayo.
Umbhobho wentsimbi ojikelezayo we-S235 JR kunye nombhobho womgca we-X70 SSAW (Spiral Submerged Arc Welded) ziimveliso ezimbini eziqhelekileyo ezisetyenziswa kakhulu kwiinkqubo zemibhobho yamanzi angaphantsi komhlaba. Umbhobho we-S235 JR uxatyiswa kakhulu ngenxa yeempawu zawo ezintle zoomatshini, nto leyo eyenza ukuba ufaneleke kwiintlobo ngeentlobo zezicelo, kuquka ukuthuthwa kwamanzi. Amandla awo okumelana nokuguquguquka phantsi koxinzelelo aqinisekisa ukuba ayahlangabezana neemfuno zezixhobo ezingaphantsi komhlaba.
Namhlanje, ngenkqubo yokufudukela kwabantu ezidolophini ekhawulezileyo, inkqubo yokuhambisa amanzi angaphantsi komhlaba ethembekileyo ibe sisitshixo sokuqinisekisa ubomi babantu. Njengeshishini eliphambili kwishishini lokuvelisa iipayipi zentsimbi, isityalo esithile sentsimbi kwiSixeko saseCangzhou, kwiPhondo laseHebei, besisoloko sibonelela ngeepayipi zeSaw Welded ezisebenza kakuhle kwiziseko zophuhliso zehlabathi ukusukela oko sasekwa ngo-1993. Iipayipi zaso zentsimbi ezijikelezayo ze-S235 JR kunye neepayipi ze-spiral ze-X70 ezifakwe kwi-arc welded, ezineempawu zazo ezibalaseleyo zoomatshini, ziye zaba zizixhobo eziphambili kwiiprojekthi zokugcina amanzi angaphantsi komhlaba.
1. Amandla aphezulu kunye nokumelana nokugqwala kuqinisekisa ukhuseleko lokudluliswa kwamanzi ixesha elide. Umbhobho ojikelezayo we-S235 JR: Unokumelana okuhle kakhulu nokuguquguquka koxinzelelo kwaye ufanelekile kwiindawo ezintsonkothileyo zejoloji, ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kombhobho. Umbhobho we-X70 SSAW: Wenziwe ngentsimbi enamandla aphezulu kunye netekhnoloji yokudibanisa i-spiral ephucukileyo, umelana noxinzelelo kwaye umelana nokugqwala, ufanelekile ukudluliswa kwamanzi okude kunye neendawo ezinzima.
2. Ubuchwepheshe obuphambili obudibene nolawulo oluqinileyo lomgangatho budala inkqubo yemibhobho ezinzileyo. Le fektri isebenzisa ubuchwepheshe be-spiral submerged arc welding (SAW) ukuze kufezekiswe imveliso efanelekileyo yeetyhubhu ezinkulu, ezinodonga oluncinci, ukuphucula ukusetyenziswa kwezinto ngelixa kuqinisekiswa ukuba zinamandla. Ngokubambisana neqela leengcali labantu abangama-680 kunye nomgca wemveliso wanamhlanje oxabisa i-680 yezigidi zeeyuan, siqinisekisa ukuba yonke imibhobho yentsimbi iyahlangabezana nemigangatho yamazwe ngamazwe, inegalelo kuphuhliso lweziseko eziluhlaza. Ngokuphuculwa kweemfuno zolawulo lwamanzi kwihlabathi liphela, imibhobho edityaniswe ngesarha yeCangzhou Steel Plant iya kuqhubeka nokubonelela ngezisombululo ezihlala ixesha elide nezingabizi kakhulu zothutho lwamanzi lukamasipala, lwezolimo nolwemizi-mveliso, ikhuthaza ukwakhiwa kweziseko ezizinzileyo zolondolozo lwamanzi.
imibhobho egayiweyo neyongiweyo eyenziwe yiCangzhou Steel Mills iyinxalenye ebalulekileyo yeenkqubo zamanzi angaphantsi komhlaba. Imibhobho eyongiweyo ye-S235 JR kunye ne-X70 spiral submarine arc, eneempawu zayo ezintle zoomatshini kunye nokumelana nezinto ezingqongileyo, ibalulekile ekuqinisekiseni ukuthuthwa kwamanzi ngokufanelekileyo. Ukujonga phambili, ukubaluleka kwezi mveliso kuya kuqhubeka kukhula, kugxininisa imfuneko yeshishini lemibhobho yentsimbi yokuvelisa okusemgangathweni ophezulu kunye nezisombululo ezintsha.
