1. Ka Nānā Huahana a me nā ʻAno Hana
ʻO S355J2H kahi papa kila kūkulu i wehewehe ʻia ma lalo o nā kūlana ʻEulopa EN 10219 (nā ʻāpana hakahaka kūkulu anu) a me EN 10210 (nā ʻāpana hakahaka kūkulu wela), i hoʻohana nui ʻia i ka hana moku, ka ʻenekinia kai, ke kūkulu ʻana, a me nā ʻāpana mīkini kaumaha. ʻO nā waiwai koʻikoʻi:
Papa Ikaika: Hōʻike ʻo S355 i ka ikaika haʻahaʻa loa o 355 MPa (no ka mānoanoa o ka paia≤16mm), me ka ikaika tensile mai 470 a 630 MPa
Paʻakikī Haʻahaʻa-Mahana: Hōʻike ʻo J2 i ka ikehu hopena Charpy≥27J ma -20°C, e hoʻokō ana i nā koi lawelawe no nā moku e hana ana ma nā kūlana ʻEulopa ʻĀkau a me ke kai anuanu
Ka Hiki ke Welded: Ka Waiwai Kūlike o ke Kalapona (CEV)≤0.45%, e hāʻawi ana i ka weldability maikaʻi e kūpono no nā hana welding nui i ke kūkulu ʻana i ka moku
Nā Kūlana Pili: EN 10219 (hoʻokumu anu ʻia) a me EN 10210 (hoʻopau wela ʻia), e kūlike ana i nā kaʻina hana like ʻole a me nā hiʻohiʻona noi
I ke kūkulu moku, hoʻohana nui ʻia nā ʻōmole huinaha S355J2H no nā ʻōnaehana hull, nā kākoʻo bulkhead, nā ʻāpana superstructure, nā ʻāpana hoʻolako, a me nā modula paepae offshore.
2. ʻIkepili o ka Noi ʻana o ka Mākeke ʻEulopa
Mālama nā ʻoihana kūkulu moku a me nā ʻenekinia kai o ʻEulopa i ke koi paʻa no nā paipu kila kūkulu ikaika kiʻekiʻe. Ua lilo nā paipu huinaha S355J2H i koho mea nui ma nā ʻāpana kai a me nā kai o ʻEulopa ma muli o ko lākou lakio ikaika-a-kaumaha maikaʻi loa a me ka paʻakikī haʻahaʻa.
ʻO nā wahi noi koʻikoʻi:
Nā Moku Kalepa: Nā ʻāpana kūkulu ʻili no nā moku ipu, nā moku lawe ukana, a me nā moku tanker
Nā Lako Hana ma waho: Nā ʻōnaehana kākoʻo no nā kahua hoʻokomo makani ma waho a me nā kahua ʻeli
Nā Moku Kūikawā: Nā moku haki hau, nā moku noiʻi polar, a me nā ʻano moku ʻē aʻe e koi ana i ka paʻakikī haʻahaʻa kiʻekiʻe
Nā Hana o ke Awa a me ka Hale Hana Moku: Nā hale uapo maloʻo a me nā lako hāpai ma ke awa
ʻO Kelemānia, Pelekiuma, Netherlands, a me Italia nā mea lawe mai ʻEulopa mua o nā paipu huinaha S355J2H. ʻO nā awa o Antwerp (Pelekiuma) a me Rotterdam (Netherlands) e lawelawe ana ma ke ʻano he mau kikowaena hoʻolaha kila nui o ʻEulopa, e lawelawe ana i nā nui o ka hoʻoili ʻana.
3. Ka Nānā ʻana i ka Leo Hoʻokomo Mai
Wahi a nā kuhi ʻikepili kālepa ʻoihana, ʻo ka hoʻokuʻu makahiki ʻana o Kina o nā paipu huinaha S355J2H i ka mākeke ʻEulopa e noho ana ma kahi o 170,000 a 220,000 tone i ka wā 2022-2023. Ua mālama nā huahana Kina i kahi māhele mākeke koʻikoʻi ma ʻEulopa ma muli o ke kūlana paʻa a me ka hoʻokūkū kumukūʻai. ʻOiai ke kuleana anti-dumping o ka EU ma kekahi mau huahana kila Kina, ke koʻikoʻi nei ka lako Kina ma ka ʻāpana ʻāpana hakahaka.
4. Ka laulā kikoʻī o ka lawe ʻana mai maʻamau
ʻO ka maʻamau, lawe mai ka mākeke ʻEulopa i nā paipu huinaha S355J2H ma nā pae kikoʻī e hiki mai ana:
Palena Pae Maʻamau
Ka nui o ka paipu huinahā 20mm× 20mm a i 500mm× 500mm
Ka nui o ka paipu huinahā 40mm× 20mm a i 600mm× 400mm
Mānoanoa o ka paia 2.0mm a i 20.0mm
Ka lōʻihi 6m paʻa, 12m paʻa, a i ʻole i hoʻopilikino ʻia (a hiki i ka 18m)
Kūlana Pili EN 10219 (hana anu) / EN 10210 (hoʻopau wela)
ʻO ke koi nui loa aia ma ka pae mānoanoa o ka paia o 4-12mm a me ka pae nui o ka ʻāpana o 100-300mm, i kūpono no nā ʻōnaehana moku a me nā ʻāpana kūkulu maʻamau. ʻO nā kikoʻī paia kaumaha nui-anawaena (ʻāpana >300mm, mānoanoa o ka paia >15mm) hoʻohana nui ʻia i nā hale kaumaha ma waho.
5. Nā mea lawe mai nui a me nā mea hoʻolako
Nā mea hoʻokomo waiwai koʻikoʻi o ʻEulopa:
Ma muli o ka ʻikepili kālepa, ua kau nui ʻia nā hana lawe mai o ka paipu huinaha S355J2H ma ka mākeke ʻEulopa ma nā ʻāina aʻe:
Kelemania: Hoʻoulu nā ʻoihana hana ikaika a me nā ʻoihana kaʻa i ke koi no ke kila kūkulu kiʻekiʻe
Pelekiuma: ʻO ke awa ʻo Antwerp kahi kikowaena kālepa kila nui, me nā nui i hoʻomaʻemaʻe ʻia a hāʻawi ʻia ma ʻaneʻi
Netherlands: ʻO ke awa ʻo Rotterdam kekahi puka kila koʻikoʻi ʻEulopa, me ke kūkulu ʻana i loko o ka home a me ka hana ʻana i nā lako mahiʻai e kōkua pū ana i ke koi
ʻItalia: Hoʻoulu ka hana ʻoihana a me nā papahana ʻoihana i ka noi no nā paipu kila kūkulu
Palani a me Polani: Kākoʻo nā mākeke kūkulu paʻa a me ka ulu ʻana o ka ʻoihana i nā nui o ka lawe ʻia mai
Nā Mea Hoʻolako Nui:
(I) Nā Mea Hoʻolako ma ʻEulopa
ʻO ArcelorMittal: He mea hana kila honua alakaʻi i hiki ke hoʻolako i nā ʻāpana hakahaka S355J2H e kūlike me nā kūlana EN 10210 a me EN 10219, e uhi ana i nā laina huahana i hoʻopau ʻia a me ke anu no nā noi ikehu onshore a me offshore.
6. Nā Koina no ke Komo ʻana i ka Mākeke
ʻO ka hoʻokuʻu aku ʻana i nā paipu huinaha S355J2H i ka mākeke ʻEulopa e pono ai ka mālama ʻana i nā koi hoʻoponopono ma lalo nei:
Hōʻike Hōʻailona CE & DoP: Ma lalo o ke Kānāwai Huahana Kūkulu EU (CPR 305/2011/EU), pono e hoʻopuka ʻia kahi Hōʻike Hana (DoP) a hoʻopili ʻia ka hōʻailona CE
Nā Palapala Hōʻoia Nānā: ʻO ka maʻamau, pono nā palapala hōʻoia nānā EN 10204 Type 3.1 a i ʻole 3.2, i hōʻoia ʻia e nā kino ʻaoʻao ʻekolu e like me TÜV, LR, BV, a i ʻole SGS.
Ka hiki ke hahai ʻia: Pono e hōʻailona ʻia kēlā me kēia paipu me ke kila kila, ka helu wela, a me ka helu maʻamau e hōʻoia i ka hiki ke hahai piha ʻia
Ka Mana Ana a me ka ʻIli: Hoʻopaʻa pono i nā koi hoʻomanawanui ana ma EN 10219-2/EN 10210-2
Ka manawa hoʻouna: Iulai-23-2026
