Ka manawa o waena o ka hoʻomaka a i ka wā pau:7-30 mau lā, Hoʻouna pololei ʻia ka hale hana wikiwiki, me nā nānā ʻaoʻao ʻekolu e SGS, BV, a i ʻole TUV i kākoʻo piha ʻia ma mua o ka hoʻouka ʻana.
Q1: Hiki i nā kukuna H GB Q355B ke pani pololei iā EN S355JR a me ASTM A572 Gr.50?
A: ʻAe. Hoʻohālikelike ʻo Q355B iā S355JR a me ASTM A572 Gr.50 i nā waiwai mechanical koʻikoʻi, me ka ikaika hua liʻiliʻi o 345–355 MPa. Hana ia ma ke ʻano he pani pololei kūpono, ʻaʻole pono e hoʻoponopono i nā helu kūkulu a i ʻole nā kiʻi kūkulu.
Q2: He aha ka ʻokoʻa o ka paʻakikī o ka hopena ma waena o Q355B a me S355JO?
A: Loaʻa iā Q355B kahi hoʻāʻo hopena lōʻihi 20°C (≥34 J), like me ka papa S355JR ʻEulopa. No nā papahana ʻāina anu e koi ana i ke kūlana S355JO (kū'ē i ka hopena 0°C), hiki iā mākou ke hoʻoponopono i nā ʻāpana micro-alloying i ka wā o ka hana ʻana e hoʻokō i nā koi hopena 0°C, me nā palapala hōʻoia hoʻāʻo wili kūhelu i hāʻawi ʻia no ka hōʻoia.
Q3: He aha nā lōʻihi maʻamau i hāʻawi ʻia, a pehea lākou e pili ai i ka hoʻouna ʻana?
A: ʻO kā mākou lōʻihi maʻamau he 6m, 9m a me 12m.
- Ka hoʻouna ʻana i nā ipu: I mea e kūpono ai i nā ipu maʻamau 20 kapuaʻi/40 kapuaʻi (ʻo ka lōʻihi o loko he 11.8m), ke paipai nei mākou i nā lōʻihi ma lalo o 11.8m e pale aku i nā pilikia hoʻouka.
- Ka hoʻouna ʻana i nā moku nui: Loaʻa nā lōʻihi piha 12m a me nā nui lōʻihi no nā kauoha papahana nui.
Q4: Loaʻa nā ʻano hana pale ʻili anti-corrosion no nā noi waho?
A: ʻAe. Hāʻawi mākou i nā koho hoʻopau ʻili maʻalahi no nā hiʻohiʻona papahana like ʻole:
- Ke kila ʻōlohelohe ʻeleʻele: Kūpono no ka hoʻohana ʻana i loko a me ka hana lua ma kahi.
- Uhi mua anti-popo: Kāohi i ka oxidation a me ka popo i ka wā e lawe ʻia ai i ke kai a me ka mālama ʻana i ka wā pōkole.
- Hoʻoheheʻe wela: Hana i kahi uhi zinc mānoanoa a paʻa no ke kūpaʻa lōʻihi i ka pala. ʻO ia ke koho kūpono no nā wahi kahakai, pulu, ʻoihana a me nā wahi waho ʻino e hoʻolōʻihi i ke ola lawelawe kūkulu.
Q5: Pehea e hōʻoia ʻia ai ka maikaʻi o ka huahana a me ka hiki ke loaʻa piha?
A: Kākoʻo nā hoʻouna āpau i ka hiki ke hahai piha ʻia. Hāʻawi ʻia kēlā me kēia pūʻulu me kahi palapala hōʻoia hoʻāʻo wili EN 10204 3.1, e uhi ana i ka helu wela piha, ka haku mele kemika a me ka ʻikepili hana mechanical. Kākoʻo piha mākou i ka hoʻouka mua ʻana i nā laʻana ʻaoʻao ʻekolu a me nā nānā ʻana e nā ʻoihana mana e like me SGS, BV a me TUV.
