Ipayipi lensimbi engagqwali elishiselwe akhiwa ngokwakha amashidi ensimbi ngendlela yeshubhu bese eshisela umthungo. Zombili izinqubo ezakheke ngokushisayo nezibandayo zisetshenziselwa ukudala amashubhu angenasici, inqubo ebandayo ikhiqiza isiphetho esibushelelezi kanye nokubekezelelana okuqinile kunokwakheka okushisayo. Zombili izinqubo zakha ipayipi lensimbi engagqwali elimelana nokugqwala, elibonisa amandla aphezulu nokuqina.

Ipayipi lensimbi engagqwaliibuye ihlanzwe kalula futhi ifakwe inzalo futhi ingashiselwa kalula, yenziwe ngomshini, noma igotshwe ukuze kwakheke umumo ogobile. Le nhlanganisela yezinto yenza ipayipi lensimbi engagqwali libe yisinqumo esihle kakhulu sokwenziwa kwesakhiwo, ikakhulukazi lezo lapho amashubhu engase achayeke khona endaweni egqwalayo.

Ngomhla lu-1 kuNovemba 2024, i-US International Trade Commission (USITC) yaqala ukubuyekezwa kwesithathu kokushona kwelanga kokulahlwa kwelanga (AD) kanye nemisebenzi ephikisanayo (CVD) kumapayipi okucindezela ensimbi engenasici ashiselwe avela e-China, kanye nokubuyekezwa kokushona kwelanga kwesibili kwe-AD. imisebenzi emikhiqizweni efanayo evela e-Malaysia, Thailand, nase-Vietnam, ukuze kunqunywe ukuthi ukukhanselwa kwama-oda akhona e-AD kanye ne-CVD emikhiqizweni yesihloko kungenzeka yini kuholele ekutheni ukuqhubeka noma ukuphindeka kokulimala kwempahla embonini yase-US phakathi nesikhathi esingabonwa ngaphambili.

Ngomhla zi-4 kuNovemba, uMnyango Wezohwebo wase-US (USDOC) umemezele ukuqaliswa kokubuyekezwa kokushona kwelanga kwe-AD yesithathu kanye ne-CVD emikhiqizweni yezihloko ezivela e-China, kanye nokubuyekezwa kwesibili kokushona kwelanga kwe-AD emikhiqizweni efanayo evela e-Malaysia, Thailand, nase-Vietnam.

Izinhlangothi ezinentshisekelo kufanele zithumele impendulo yazo kulesi saziso ngolwazi oludingekayo kuze kube umnqamulajuqu wangomhla zi-2 kuZibandlela wezi-2024, futhi ukuphawula kokwanela kwezimpendulo kufanele kufakwe ngoJanuwari 2, 2025.

300 series gradeinsimbi engagqwaliikhiqizwa ibe uhla lwemikhiqizo ehlanganisa amashubhu ensimbi, amapayipi ensimbi, neminye imikhiqizo ehlukahlukene. Womabili amashubhu ensimbi angu-304 kanye nangu-316 angama-alloys asekelwe ku-nickel okulula ukuwanakekela, amelana nokugqwala, futhi agcina amandla nokuqina emazingeni okushisa aphezulu.

Ukunquma ukuthi yiliphi ibanga lensimbi elilungele uhlelo lwakho lokusebenza kuncike ekusetshenzisweni okuhlosiwe kanye nezici zemvelo ezifana nezinga lokushisa noma ukuchayeka ku-chloride.

• Uhlobo lwensimbi engu-304 alukwazi ukugqwala futhi kulula ukulucolisa, okulwenza lube uhlobo oluvame kakhulu lwensimbi engagqwali esetshenziselwa amashubhu nezinye izingxenye zensimbi. Amashubhu ensimbi engagqwali angu-304 avame ukusetshenziswa ekwakheni nasekuhlobiseni izinhlelo zokusebenza.
• Thayipha insimbi engagqwali engu-316 ifana ne-304 engagqwali ngoba iphinde imelane nokugqwala futhi kulula ukuyihlanza. I-316 i-stainless, kodwa, inenzuzo encane ngoba kodwa imelana kakhulu nokugqwala okubangelwa i-chloride, amakhemikhali, nezinyibilikisi. Lesi sici esengeziwe senza insimbi engagqwali engu-316 ibe yisixazululo esithandwayo lapho kukhona ukuchayeka njalo kumakhemikhali noma izinhlelo zokusebenza zangaphandle lapho kukhona ukuchayeka kusawoti. Izimboni ezaziwayo zisebenzisa i-316 insimbi engagqwali zihlanganisa izimboni, ukuhlinza, nezasolwandle.
