Ipuleti lensimbi eligoqekile laseShayina lifaneleka kanjani kumaphrojekthi engqalasizinda eMelika Ephakathi? Ukuhlaziywa okuphelele kwamamaki abalulekile njenge-Q345B

Izinto ezibalulekile ezithengwe eShayina eMelika Ephakathi kanye nezicelo zazo

(I) Insimbi enamandla aphezulu, ene-alloy ephansi: Q345B
I-Q345B iyinto "okumelwe ibe nayo" kumaphrojekthi engqalasizinda aseMelika Ephakathi. Njengoba inamandla okukhiqiza angu-345 MPa, ihlanganisa ukushibilika okuhle kakhulu kanye nokumelana nokushayisana. Ihambisana nezindinganiso ze-GB/T futhi inesitifiketi se-ISO9001.

Emisebenzini emibili emikhulu yokwandisa amapayipi endle eNicaragua, kwathengwa amathani ayi-1,471.26 e-Q345B hot-rolled Larsen steel sheet piles ngesikhathi esisodwa. Lawa asetshenziselwa ukwakha isisekelo samapayipi endle angamakhilomitha angu-87.2, iziteshi zokupompa ezinhlanu, kanye nesitshalo esisodwa sokuhlanza indle. Atholakala ngobude obuyi-9m, 12m, kanye no-15m, afanelana kahle nokujula okudingekayo kwephrojekthi engaphansi komhlaba. Inzuzo eyinhloko yale nto ukuqina kwesakhiwo sayo ezindaweni ezishisayo nezinemvula, kuyilapho inikeza isilinganiso sentengo nokusebenza esidlula kakhulu esemikhiqizo efanayo yendawo.

(II) Insimbi Yesakhiwo Sekhabhoni Esezingeni Eliphezulu: Uchungechunge lwe-SPHT1 kanye ne-SAE

I-SPHT1: Njengensimbi yokunyathela ngaphansi kwezindinganiso ze-JIS zaseJapan, i-SPHT1 isibe yindlela ekhethwayo yokwakha ingqalasizinda eDominican Republic ngenxa yokuqina kwayo okuphezulu kanye nokuqina. I-Royal Steel ngaphambilini yayenze ngokwezifiso amathani angu-900 e-SPHT1 hot-rolled coil yeklayenti laseDominican. Ngemva kokwenza ngcono amapharamitha okunyathela kanye nokucutshungulwa okwengeziwe kube amapayipi, i-SPHT1 yasetshenziswa ekwakhiweni kwamapayipi asemadolobheni. Amandla ayo alinganiselayo kanye nokwakheka kwayo kwenza yafanelekela izidingo ezivamile zokubeka amapayipi eMelika Ephakathi.

I-SAE 1006/1008: Lezi zinsimbi ezimbili ezigoqwa nge-hot-rolled ezinekhabhoni ephansi ziyizinto eziyinhloko zokukhiqiza izingxenye zesakhiwo ezilula. I-Royal Steel Group yake yathumela amathani ayi-14,000 ama-coil e-SAE 1008 agoqwa nge-hot-rolled eBrazil.

(III) Insimbi Yesakhiwo Esishintsha Isimo Sezulu: A588 Gr B
Insimbi yokushisa i-A588 Gr B, enesendlalelo sayo sokugqwala esiziphilisayo, ithole isabelo semakethe ezindaweni ezinomswakama ophezulu kanye nezindawo ezigqwala kakhulu ezitholakala ezingxenyeni zaseMelika Ephakathi.
IMexico yake yangenisa amathani angu-3,000 amapuleti ensimbi ashiswayo e-A588 Gr B avela enkampanini yethu ukuze asetshenziswe ekwakhiweni kwengqalasizinda yamabhuloho asogwini kanye nechweba.

(IV) Insimbi Yekhabhoni Ejwayelekile: Izimpahla Eziyisisekelo ze-SS400 kanye ne-ASTM A36
I-SS400 (izinga elijwayelekile laseJapan) kanyeI-ASTM A36(izindinganiso zaseMelika) "ziyizinto ezibalulekile ezisetshenziswayo" embonini yaseMelika Ephakathi. Njengoba zinamandla okukhiqiza angu-245 MPa kanye no-250 MPa, ngokulandelana, zifanelekela izingxenye zesakhiwo ezithwala umthwalo ophansi kanye nokukhiqizwa kwemishini ejwayelekile. Amakhasimende aseColombia aseRoyal Steel Group athenga kakhulu amapuleti ensimbi anephethini angu-3.0mm enziwe nge-SS400 ukuze avimbele ukushelela ezindaweni zokuthutha nezokwakha.
