IMarike yeHlabathi yeDuctile Iron Pipe: Imbono Ethembisayo

Ihlabathi liphelaumbhobho wesinyithi othambileyoImarike iza kukhula ngokuthe chu. Olu kukhula luqhutywa zizinto ezimbini eziphambili: ukonyuka kotyalo-mali kwiziseko zophuhliso kunye nesidingo sokutshintsha imibhobho emidala. Imibhobho yentsimbi ye-ductile lukhetho oluthembekileyo lokubonelela ngamanzi, ukuhanjiswa kwegesi, kunye nokusetyenziswa kwemizi-mveliso. Kuqikelelwa ukuba imfuno yemibhobho ye-ductile iya kunyuka ngesantya sokukhula sonyaka esidibeneyo (CAGR) se-6% ukuya kuthi ga ngo-2030. I-China ngumthengi omkhulu, ebala ngaphezulu kwe-40% yokusetyenziswa kwehlabathi.
Ezinye iisayizi zepayipi eziphambili ziya zithandwa kakhulu. Umzekelo,Umbhobho wesinyithi othambileyo oyi-100mmkunye nemibhobho yesinyithi ethambileyo ene-intshi ezi-6 isetyenziswa ngakumbi kwiiprojekthi zikamasipala kunye neenkqubo zokhuseleko lwamanzi emaphandleni. Kwiimarike ezinkulu zaseAsia, ixabiso lemibhobho yesinyithi ethambileyo ene-150mm okwangoku liphakathi kwe-$520 kunye ne-$590 ngetoni. Eli xabiso lichaphazeleka lixabiso lezinto eziluhlaza kunye netekhnoloji yemveliso. Ixabiso lemibhobho yesinyithi ethambileyo likwachaphazeleka zizinto ezichasene nokugqwala kunye nobukhulu beendonga zemibhobho. Iimveliso zeklasi zeK9 ezisebenza kakuhle zibiza kakhulu ngenxa yemigangatho yomgangatho engqongqo.
Inkxaso yomgaqo-nkqubo ikwanceda imakethi ukuba ikhule. "Isicwangciso se-14 seminyaka emihlanu saseTshayina" kunye nophuhliso lweziseko zehlabathi phantsi kweBelt and Road Initiative ziyayinyusa imfuno yeepayipi zentsimbi ezithambileyo. Iiprojekthi zokuhlaziya izixeko kunye nokutshintshwa kweepayipi ezindala kugcina imfuno yezi payipi izinzile. Kwangaxeshanye, ukuphuculwa kwetekhnoloji ekusetyenzisweni kwe-smart casting kunye nokuvelisa okuluhlaza kwenza iimveliso zikhuphisane ngakumbi.

Umthamo weepayipi zesinyithi ezithuthwayo kumazwe angaphandle kulindeleke ukuba ukhule nge-10% rhoqo ngonyaka. UMzantsi-mpuma we-Asia kunye noMbindi Mpuma zivela njengemimandla ebalulekileyo yokukhula.
Ukuqukumbela, imakethi yemibhobho yesinyithi ethambileyo ixhamla kwinkxaso eqinileyo yomgaqo-nkqubo kwaye ineendlela ezahlukeneyo zokusetyenziswa. Nangona kunokubakho imingeni emincinci ngenxa yokuguquguquka kwamaxabiso ezinto eziluhlaza, umbono wexesha elide ulungile. Iimveliso eziphambili ezifana nemibhobho yesinyithi ethambileyo eyi-100mm kunye ne-6-intshi ziya kukhokela ukukhula kwemarike. Oku kuthetha ukuba ikamva lemakethi yemibhobho yesinyithi ethambileyo libonakala liqaqambile, kunye nokukhula okuqhubekayo kunye nophuhliso kwiminyaka ezayo.
Kumashishini akwishishini lemibhobho yesinyithi ethambileyo, kufuneka anikele ingqalelo kwezi ndlela. Angagxila ekuveliseniedumileyoumbhobho we-ductileubukhulukunye nokuphucula iteknoloji yabo yemveliso ukuze ihlangabezane nemigangatho ephezulu yomgangatho. Ngokwenza njalo, banokusebenzisa ithuba lemarike ekhulayo kwaye bafumane iziphumo zoshishino ezingcono. Kwakhona, ngokukhula kweemarike zokuthumela ngaphandle, iinkampani zinokuhlola amathuba amatsha eMzantsi-mpuma Asia nakuMbindi Mpuma. Ngokubanzi, imakethi yepayipi yesinyithi ethambileyo inika amathuba amaninzi okukhula nempumelelo.
