1. Isishwankathelo seMveliso kunye neempawu zobugcisa
I-S355J2H ludidi lwentsimbi oluyilwe ngokwemigangatho yaseYurophu i-EN 10219 (amacandelo angenanto akhiweyo abandayo) kunye ne-EN 10210 (amacandelo angenanto agqitywe shushu), asetyenziswa kakhulu kumacandelo okwakha iinqanawa, ubunjineli basemaphandleni, ulwakhiwo, kunye noomatshini abakhulu. Iimpawu eziphambili ziquka:
Udidi lwamandla: I-S355 ibonisa amandla amancinci okuvelisa angama-355 MPa (kubukhulu bodonga≤16mm), kunye namandla okutsalwa aqala kwi-470 ukuya kwi-630 MPa
Ukuqina kobushushu obuphantsi: I-J2 imele amandla empembelelo kaCharpy≥27J kwi -20°C, ukuhlangabezana neemfuno zenkonzo yeenqanawa ezisebenza kwiimeko zaseMantla Yurophu nakwiimeko zolwandle olubandayo
Ukudityaniswa: Ixabiso Elilinganayo leKhabhoni (i-CEV)≤0.45%, nto leyo enika ukuwelda okuhle okufanelekileyo kwimisebenzi yokuwelda emikhulu ekwakheni iinqanawa
Imigangatho Esebenzayo: EN 10219 (eyenziwe ngokubandayo) kunye ne-EN 10210 (egqityiweyo shushu), ehambelana neenkqubo ezahlukeneyo zokuvelisa kunye neemeko zokusetyenziswa
Ekwakhiweni kweenqanawa, iityhubhu zesikwere ze-S355J2H zisetyenziswa kakhulu kwizakhelo zeenqanawa, iinkxaso ze-bulkhead, izinto ze-superstructure, iindawo zokufaka iimpahla, kunye neemodyuli zeplatifomu zaselwandle.
2. Isishwankathelo seSicelo seMarike yaseYurophu
Amashishini okwakha iinqanawa eYurophu kunye nobunjineli basemaphandleni agcina imfuno ezinzileyo yeetyhubhu zentsimbi ezakhiweyo ezinamandla aphezulu. Iityhubhu zesikwere ze-S355J2H ziye zaba lukhetho oluphambili lwezinto zokwakha kwiinkalo zaselwandle zaseYurophu kunye nasemaphandleni ngenxa yomlinganiselo wazo ogqwesileyo wamandla nobunzima kunye nokuqina kobushushu obuphantsi.
Iindawo eziphambili zesicelo ziquka:
Iinqanawa Zorhwebo: Izixhobo zokwakha iinqanawa zeekhonteyina, iinqanawa ezithwala izinto ezinkulu, kunye neenqanawa zokuthutha imithwalo
Izixhobo zaselunxwemeni: Izakhiwo zenkxaso zamaqonga okufakelwa komoya aselunxwemeni kunye namaqonga okugrumba
Iinqanawa Ezikhethekileyo: Iinqanawa zokuqhekeza umkhenkce, iinqanawa zophando ezikwi-polar, kunye nezinye iintlobo zeenqanawa ezifuna ukuqina okuphezulu kubushushu obuphantsi
Izixhobo zeZibuko kunye neNdawo yokuHamba ngeenqanawa: Izakhiwo zedokhi ezomileyo kunye nezixhobo zokuphakamisa ecaleni kwe-quayside
IJamani, iBelgium, iNetherlands, kunye ne-Itali zezona zingenisa iityhubhu zesikwere ze-S355J2H eYurophu. Amazibuko ase-Antwerp (eBelgium) naseRotterdam (eNetherlands) asebenza njengeendawo ezinkulu zokusasaza intsimbi eYurophu, ephatha ubungakanani obukhulu bokudluliselwa kwempahla.
3. Uhlalutyo lomthamo wokungenisa
Ngokwezibalo zorhwebo lweshishini, ukuthunyelwa kwe-S355J2H ngonyaka eTshayina kwiityhubhu zesikwere kwimarike yaseYurophu kuhlale kuluhlu olumalunga ne-170,000 ukuya kwi-220,000 yeetoni ngexesha lowama-2022-2023. Iimveliso zaseTshayina zigcine isabelo semarike esibonakalayo eYurophu ngenxa yomgangatho ozinzileyo kunye nokukhuphisana kwamaxabiso. Nangona i-EU inoxanduva lokulwa nokulahla inkunkuma kwiimveliso ezithile zentsimbi zaseTshayina, unikezelo lwaseTshayina luhlala lubalulekile kwicandelo leendawo ezingenanto.
4. Uluhlu lweeNkcukacha zokungenisa izinto eziqhelekileyo
Imarike yaseYurophu idla ngokungenisa iityhubhu zesikwere ze-S355J2H kwezi zigaba zilandelayo zeenkcukacha:
Ipharamitha Uluhlu Oluqhelekileyo
Ubungakanani beTube yesikwere 20mm× 20mm ukuya kwi-500mm× 500mm
Ubungakanani beTube engunxande 40mm× 20mm ukuya kwi-600mm× 400mm
Ubukhulu bodonga 2.0mm ukuya kwi-20.0mm
Ubude I-6m esisigxina, i-12m esisigxina, okanye eyenziwe ngokwezifiso (ukuya kuthi ga kwi-18m)
Umgangatho oSebenzayo I-EN 10219 (i-cold-form) / EN 10210 (igqityiwe ishushu)
Eyona mfuno iphambili ikwinqanaba lobukhulu bodonga oluyi-4-12mm kunye nobubanzi becandelo obuyi-100-300mm, ezifanelekileyo kwizakhelo zeenqanawa kunye nezinto zokwakha ngokubanzi. Iinkcukacha zodonga olunzima olunobukhulu obukhulu (icandelo >300mm, ubukhulu bodonga >15mm) zisetyenziswa kakhulu kwizakhiwo ezinzima zaselwandle.
