1. Ukubuyela kweMfuno yeNtsimbi yeHlabathi kunye noKwahluka kweNgingqi
I-World Steel Association iqikelela ukuba imfuno yentsimbi yehlabathi iya kunyuka nge-1.2% ngo-2025, ifikelele kwi-1.772 yeebhiliyoni zeetoni, iqhutywa kukukhula okuqinileyo kuqoqosho olusakhulayo olufana ne-India (+8%) kunye nokuzinza kwiimarike eziphuhlileyo. Nangona kunjalo, imfuno yentsimbi yaseTshayina kulindeleke ukuba yehle nge-1%, ichaphazeleka licandelo lezindlu elicothayo kunye nemizamo karhulumente yokuphucula izakhiwo zoshishino49. Abahlalutyi bagxininisa ukuba utyalo-mali lweziseko zophuhliso zaseIndiya kunye nokwandiswa kweemoto zezona zinto ziphambili ezibangela ukukhula, ngelixa i-China igxile "kuphuhliso olusemgangathweni ophezulu" ngokuhlaziya imveliso eluhlaza kunye notshintsho lwekhonkco lokubonelela.
Ukuvezwa kweMveliso:
• Iipayipi ze-ASTM A53: Zisetyenziswa kakhulu ekuthuthweni kweoyile, igesi, namanzi ngenxa yokuqina kwazo kunye nokuthobela imigangatho yamazwe ngamazwe.
• Amaphepha entsimbi erhabaxa: Imfuno ephezulu yokwakha uphahla kunye ne-cladding, inconywa ngobomi bayo obungaphezu kweminyaka engama-20 kunye nokusebenza kakuhle kweendleko.
2. Izithintelo zeKhabhoni Zitshintsha Utshintsho kwiShishini
Icandelo lesinyithi lijongene nokuqina "kwemida yokukhupha ikhabhoni ye-ton-steel" phantsi kwe "Sicwangciso seMinyaka emihlanu se-15 saseTshayina," esinyanzela iinkampani ukuba zamkele ubuchwepheshe bekhabhoni ephantsi. Iingcali zigxininisa ukuba amaxabiso ekhabhoni kunye nokubhalwa kweempawu zekhabhoni kuya kuba yinto ebalulekileyo ekukhuphisaneni kwimarike. Amanyathelo afana nokwenza isinyithi esisekelwe kwi-hydrogen kunye nokuphuculwa kokusebenza okuqhutywa yi-AI aya ethandwa, kunye nabadlali abakhulu abanjengoBaowu Steel kunye ne-ArcelorMittal abakhokela iiprojekthi zovavanyo.
Ukubaluleka kweepayipi ze-ASTM A53 kwiShishini leNsimbi
Izicelo ezibanzi
Iipayipi ze-ASTM A53 zibonisa ukuguquguquka okumangalisayo kwiindlela ezahlukeneyo zokusebenza kumashishini afana nokuvelisa, ioyile negesi, ukubonelela ngamanzi, kunye nemibhobho. Zisebenza njengemijelo yamanzi afana namanzi, ioyile, negesi, kwaye zibalulekile kwizakhiwo zokwakha izakhelo, iibhulorho, kunye nemibhobho. Amandla eepayipi ze-ASTM A53 okulungiselela ukugqitywa komphezulu okugqwesileyo, amanqanaba, kunye neempawu zenza ukuba zibe yimfuneko ekuhlangabezaneni neemfuno ezahlukeneyo zeeprojekthi ezahlukeneyo.
Ukunyaniseka kwesakhiwo kunye nokuthembeka
Iipayipi ze-ASTM A53 zaziwa ngokuthembeka kwazo kwesakhiwo, nto leyo eyenza ukuba zibe lolona khetho luphezulu kwizicelo ezibalulekileyo. Ezi pipes ziyavavanywa kwaye zilandela iimfuno ezingqongqo zokuqina okuneeleyara, iimpawu zoomatshini, kunye nezakhiwo ezidityanisiweyo. Ukuqinisekiswa kokuthembeka okusisiseko okubonelelwa yizikhokelo zeepayipi ze-ASTM A53 kuqinisekisa ukuthembeka kunye namandla eeprojekthi zesakhelo, kongeza uphuculo olusebenzayo, kwaye kuqinisa ukusebenza kwayo kunye nokuthembeka phakathi kwabayili bezakhiwo, abasebenzi abaqeshiweyo, kunye nabachaphazelekayo.
Igalelo kuPhuhliso lweZiseko zoPhuhliso
Iipayipi ze-ASTM A53 zidlala indima ebalulekileyo ekwakhiweni kweziseko zophuhliso ngokubonelela ngezisombululo ezihlala ixesha elide nezingabizi kakhulu zokuhambisa ulwelo kunye nezakhiwo ezixhasayo. Zisetyenziswa kakhulu kuphuhliso lwasezidolophini, kwizakhiwo zoshishino, nakwiiprojekthi zeziseko zophuhliso zasemaphandleni. Iipayipi ze-ASTM A53 zinegalelo ekudalweni kweziseko zophuhliso ezizinzileyo nezizinzileyo, zivumela uphuhliso lwenethiwekhi yezothutho, iinkonzo, izakhiwo kunye nezinye izinto ezibalulekileyo kuluntu lwanamhlanje, ngaloo ndlela ziphucula umgangatho wobomi kunye nokuchuma koqoqosho.
