Ipleyiti yesinyithi eqengqelekayo yaseTshayina ifaneleka njani kwiiprojekthi zeziseko zophuhliso kuMbindi Melika? Uhlalutyo olupheleleyo lweeklasi eziphambili ezifana ne-Q345B

Izinto eziphambili ezithengwe eTshayina kuMbindi Melika kunye nokusetyenziswa kwazo

(I) Intsimbi enamandla aphezulu, eyomeleleyo nephantsi: Q345B
I-Q345B yinto "ekufuneka ibe nayo" kwiiprojekthi zeziseko zophuhliso zaseMbindi Melika. Ngamandla okuvelisa angama-345 MPa, idibanisa ukudityaniswa okugqwesileyo kunye nokumelana nempembelelo. Ihambelana nemigangatho ye-GB/T kwaye inesiqinisekiso se-ISO9001.

Kwiiprojekthi ezimbini ezinkulu zokwandiswa kwemibhobho yamanzi amdaka eNicaragua, zizonke iitoni ezili-1,471.26 zeepali zesinyithi zeLarsen ze-Q345B eziqengqelekayo ezishushu zithengiwe ngaxeshanye. Ezi zasetyenziselwa ukwakhiwa kwesiseko seepayipi zemanzi amdaka ezingama-87.2 eekhilomitha, izitishi zokumpompa ezintlanu, kunye nesityalo esinye sokucocwa kwamanzi amdaka. Zifumaneka ngobude obuziimitha ezili-9, ezili-12, kunye ne-15, zihambelana ngokugqibeleleyo nobunzulu obufunekayo beprojekthi engaphantsi komhlaba. Inzuzo ephambili yale nto kukuzinza kwesakhiwo sayo kwiimeko zemozulu ezishushu nezinemvula, ngelixa inikezela ngomlinganiselo wexabiso nokusebenza ogqitha kakhulu lowo weemveliso zasekuhlaleni ezifanayo.

(II) Intsimbi yoLwakhiwo lweKhabhoni ekumgangatho ophezulu: SPHT1 kunye nothotho lweSAE

I-SPHT1: Njengentsimbi yokunyathela phantsi komgangatho we-JIS yaseJapan, i-SPHT1 iye yaba lolona khetho lukhethwayo lokwakha iziseko zophuhliso eDominican Republic ngenxa yokuqina kwayo okuphezulu kunye nokuqina. I-Royal Steel ngaphambili yayilungiselela iitoni ezingama-900 ze-SPHT1 coil eshushu eqengqelekayo kumthengi waseDominican. Emva kokuphucula iiparameter zokunyathela kunye nokucubungula ngakumbi kwiipayipi, i-SPHT1 yasetyenziswa ekwakheni iipayipi zasezidolophini. Amandla ayo alinganayo kunye nobuchule bayo benze ukuba ifaneleke kwiimfuno zokubeka iipayipi rhoqo eMbindi Melika.

I-SAE 1006/1008: Ezi ntsimbi zimbini ezirhuqwayo ezishushu ezinekhabhoni ephantsi zizinto eziphambili zokwenza izinto zokwakha ezikhaphukhaphu. I-Royal Steel Group yakha yathumela iitoni ezili-14,000 zeekhoyili ezishushu ze-SAE 1008 eBrazil.

(III) Intsimbi yoLwakhiwo lweMozulu: A588 Gr B
Intsimbi yokupholisa i-A588 Gr B, enomaleko wayo wokugqwala ophilisayo, ifumene isabelo semarike kwiindawo ezifumileyo nezinobuthi obuphezulu ezifumaneka kwiindawo ezithile zaseMbindi Melika.
IMexico yakha yathenga iitoni ezingama-3,000 zeepleyiti zentsimbi ezitshisiweyo ze-A588 Gr B ezivela kwinkampani yethu ukuze zisetyenziswe ekwakheni iziseko zophuhliso lweebhulorho zaselunxwemeni kunye nezibuko.

(IV) Intsimbi yekhabhoni eNjongo Jikelele: Izinto ezisisiseko ze-SS400 kunye ne-ASTM A36
I-SS400 (umgangatho waseJapan) kunyeI-ASTM A36(umgangatho waseMelika) "zizinto ezisetyenziswayo ezibalulekileyo" kushishino lwaseMbindini Melika. Ngenxa yamandla okuvelisa angama-245 MPa kunye nama-250 MPa, ngokwahlukeneyo, zifanelekile kwizixhobo zokwakha ezinomthwalo omncinci kunye nokuveliswa koomatshini ngokubanzi. Abathengi baseColombia baseRoyal Steel Group bathenga ikakhulu iipleyiti zentsimbi ezineepatheni ezingama-3.0mm ezenziwe nge-SS400 ukuze zisetyenziswe ekuthinteleni ukutyibilika kwiiplatifomu zothutho kunye nolwakhiwo.
