1. Isidingo Sensimbi Yomhlaba Wonke Sibuyela Emuva Ngokuhlukahluka Kwesifunda
I-World Steel Association ibikezela ukuthi isidingo sensimbi yomhlaba wonke sizokhuphuka ngo-1.2% ngo-2025, sifinyelele amathani ayizigidi eziyizinkulungwane ezingu-1.772, okubangelwa ukukhula okunamandla kwezomnotho osafufusa njenge-India (+8%) kanye nokuzinza ezimakethe ezithuthukile. Kodwa-ke, isidingo sensimbi saseShayina kulindeleke ukuthi sehle ngo-1%, sithonywe umkhakha wezindlu ohamba kancane kanye nemizamo kahulumeni yokuthuthukisa izakhiwo zezimboni49. Abahlaziyi baqokomisa ukuthi ukutshalwa kwezimali kwengqalasizinda yaseNdiya kanye nokwandiswa kwezimoto kuyizinto ezibalulekile ezibangela ukukhula, kuyilapho iShayina igxile “ekuthuthukisweni kwekhwalithi ephezulu” ngokukhiqiza okuluhlaza kanye nokuguqulwa kweketanga lokuhlinzeka.
Ukugqanyiswa Komkhiqizo:
• Amapayipi e-ASTM A53: Isetshenziswa kabanzi ekuthuthweni kukawoyela, igesi, kanye namanzi ngenxa yokuqina kwayo kanye nokuhambisana nezindinganiso zomhlaba wonke.
• Amashidi Ensimbi Ahlanganisiwe: Isidingo esikhulu sokwakha uphahla kanye nokufakwa kwendwangu, sinconywa ngokuphila kwazo iminyaka engaphezu kwengu-20 kanye nokusebenza kahle kwezindleko.
2. Izithiyo Zekhabhoni Zishintsha Ukwakheka Kwemboni
Umkhakha wensimbi ubhekene nokuqina "kwemikhawulo yokukhishwa kwekhabhoni yensimbi" ngaphansi "koHlelo Lweminyaka Emihlanu Lwe-15 lwaseShayina," okuphoqa izinkampani ukuthi zamukele ubuchwepheshe bekhabhoni ephansi. Ochwepheshe bagcizelela ukuthi amanani ekhabhoni kanye nokulebula kwezinyawo zekhabhoni kuzoba yinto ebalulekile ekuncintisaneni emakethe. Imizamo efana nokwenza insimbi esekelwe ku-hydrogen kanye nokuthuthukiswa kokusebenza kahle okuqhutshwa yi-AI iya ngokuya ithandwa, kanye nabadlali abakhulu abanjengoBaowu Steel kanye ne-ArcelorMittal abahola amaphrojekthi okuhlola.
Ukubaluleka Kwamapayipi E-ASTM A53 Embonini Yensimbi
Izicelo Ezibanzi
Amapayipi e-ASTM A53 abonisa ukuguquguquka okumangalisayo ezinhlobonhlobo zezicelo ezimbonini ezifana nokukhiqiza, uwoyela negesi, ukuhlinzekwa kwamanzi, kanye namapayipi. Asebenza njengemifudlana yoketshezi olufana namanzi, uwoyela negesi, kanye nokuba yizithasiselo ezibalulekile zesakhiwo sokwakha ozimele, amabhuloho, kanye namapayipi. Amandla amapayipi e-ASTM A53 okwamukela ukuqedwa okuhle kakhulu kwendawo, amamaki, kanye nemikhiqizo kuwenza abaluleke kakhulu ekuhlangabezaneni nezidingo ezahlukahlukene zamaphrojekthi ahlukahlukene.
Ubuqotho Nokuthembeka Kwesakhiwo
Amapayipi e-ASTM A53 aziwa ngobuqotho bawo besakhiwo nokuthembeka, okwenza abe ukukhetha okuphezulu kwezicelo ezibalulekile. Lawa mapayipi ayahlolwa futhi anamathela ezidingweni eziqinile zokuqina okunezingqimba, izakhiwo zemishini, kanye nezakhiwo ezihlanganisiwe. Isiqinisekiso sokuthembeka esiyisisekelo esinikezwa yiziqondiso zamapayipi e-ASTM A53 siqinisekisa ukuthembeka namandla amaphrojekthi ohlaka, sinezela ukuthuthukiswa okusebenzayo, futhi siqinisa ukusebenza kwawo kanye nokuthembeka phakathi kwabakhi bezakhiwo, izisebenzi eziqashiwe, kanye nababambiqhaza.
Igalelo Ekuthuthukisweni Kwengqalasizinda
Amapayipi e-ASTM A53 adlala indima ebalulekile ekwakhiweni kwengqalasizinda ngokuhlinzeka ngezixazululo eziqinile nezingabizi kakhulu zokuhambisa uketshezi kanye nezakhiwo ezisekelayo. Asetshenziswa kabanzi ekuthuthukisweni kwamadolobha, ezakhiweni zezimboni, kanye namaphrojekthi engqalasizinda yasemakhaya. Ipayipi le-ASTM A53 lisiza ekudalweni kwengqalasizinda eqinile futhi eqhubekayo, okwenza kube nokuthuthukiswa kwamanethiwekhi ezokuthutha, izinsiza, izakhiwo kanye nezinye izinto ezibalulekile emphakathini wanamuhla, ngaleyo ndlela kuthuthukiswe ikhwalithi yokuphila kanye nokuchuma komnotho.
