I-ASTM A572 vs ASTM A992 Iibhanti zeFlange ezibanzi: Umahluko oPhambili, Uthelekiso lwaMandla kunye noKhetho oluBalaseleyo

Kwizakhiwo zezakhiwo zentsimbi zanamhlanje,Iimitha ze-Windima njengelungu eliphambili elimelana nomthwalo kwisakhelo, nto leyo ukukhethwa kwezinto ezisetyenzisiweyo kunefuthe elikhulu kukhuseleko kunye neendleko zesakhiwo. Ngowuphi umahluko omkhulu phakathi kwemigangatho emibini edumileyo ekhankanyiweyo kwimarike ngoku -I-ASTM A572 Ibanga lama-50kwayeI-ASTM A992Abasebenzi bezobugcisa beRoyal Steel ngabona batoliki bachanekileyo.

I-A992: Umgangatho weshishini owenzelwe ngokukodwa iinjini "ezibanzi"

Ibanga lama-50 le-A572, nangona lidumile kwishishini lentsimbi, i-ASTM A992 'ngumgangatho wegolide' weImisebe ye-Wnamhlanje.

Umahluko kwi-Press kunye nohlobo lweMveliso: I-A572 yinkcazo ngokubanzi yeepleyiti, iibha kunye nezinye iiprofayili kodwa i-A992 yeyokuba iibheringi ezibanzi ezijikelezileyo ezishushu.

Ukuphuculwa kweeKhemikhali: I-A992 iqinile ngakumbi ngokweekhemikhali, nto leyo ekhokelela kumgangatho ophezulu wentsimbi ngokongezwa kwezinto ezincitshisiweyo (vanadium, niobium, copper kunye nickel).

Uthelekiso lwentsebenzo engundoqo: Kutheni i-A992 ithatha indawo ye-A572 kancinci kancinci?

Kuyilo lwesakhiwo, i-A992 ibonisa iingenelo ezibalulekileyo:

Ulawulo lweSilinganiselo sokuThamba esiVumelekileyo: I-A992 icacisa umlinganiselo ophezulu wokukhupha amandla kwi-tensile ratio ongekho ngaphezulu kwe-0.85. Olu buchule bugqwesileyo lwenza ukuba ibe ngcono kwizakhiwo ezithandwa ziinyikima, nto leyo evumela ukufunxwa kwamandla ngcono.

UkuxinanaNgenxa yomda ophezulu ongqongqo we-A992 kwi-carbon equivalent, ukuwelda kwayo ebaleni kuzinzile ngakumbi kune-A572, nto leyo enciphisa ngempumelelo umngcipheko wokuqhekeka kwe-weld.

Amandla Ukungaguquguquki: I-A992 icacisa amandla okuvelisa aphantsi angama-50 ksi (malunga ne-345 MPa) kwaye imisela umda wamandla okuvelisa aphakamileyo, iqinisekisa ukuqikelela ngokuchanekileyo uxinzelelo ngexesha loyilo lwesakhiwo.

Ubonelelo lwemarike kunye nesatifikethi esiphindwe kabini

Njengomthengisi wentsimbi ohamba phambili kwihlabathi liphela, iRoyal Steel iqaphele oku kulandelayo kwimisebenzi yayo yokuthumela ngaphandle:

Umgangatho Omiselweyo: Kwiimarike zezixhobo zokwakha ezikumgangatho ophezulu zaseMntla Melika naseLatin America,Intsimbi yeFlange ebanzingokubanzi ithathwa njenge-A992.

Isatifikethi esiphindwe kabini: Uninzi lwentsimbi ye-A992 ekumgangatho ophezulu kwimarike ikwahlangabezana neemfuno ze-A572 Grade 50. Oku kuthetha ukuba abathengi abathenga i-A992 badla ngokufumana iipropati ezibonakalayo eziphezulu xa kuthelekiswa ne-A572.

Ingcebiso yeRoyal Steel

"Xa ukhethaimiqadi yeflange ebanzi, ukuba iprojekthi yakho ibandakanya ukuwelda okuntsonkothileyo okanye ikwindawo enokubangelwa yinyikima, i-A992 lukhetho lokuqala olungenakuphikiswa,” yatsho intloko yeSebe lezoRhwebo lwaMazwe ngaMazwe leRoyal Steel.

Okwangoku,Intsimbi yasebukhosini yaseTshayinaigcina amashumi amawaka eetoni zeenkcukacha ze-A992 kunye ne-A572 kwisitokhwe kumazibuko afana neTianjin, Qingdao, kunye neShanghai. Ngamava eminyaka eli-12 ekuthumeleni isinyithi kwamanye amazwe, asiboneleli nje kuphela ngeemveliso ezikumgangatho ophezulu ezihlangabezana nemigangatho ye-ASTM yase-US, kodwa sikwabonelela ngenkxaso yobugcisa eyenzelwe wena ngokusekelwe kwiimfuno zeprojekthi zabathengi bethu.
