He whakamārama hōhonu o ngā tawhā hangarau mō te Puranga Rau Rino Momo-U

Me ngā hononga i runga i te tuaka kūpapa,Ngā puranga Uhe ōrite, ā, ka puta he tohatoha ahotea ōrite me te modulus wāhanga teitei. E aro ana tēnei poto ki tō rātou hiranga ā-mīhini, ngā paerewa EN/JIS me ngā whanaketanga maitai-matomato i te tau 2026.

Ngā Hangarau Hanganga

Ko te kaupapa matua o te hoahoaNgā puranga rino momo-Ukei roto i te meka kei runga i teTuaka Kūpapao te taiepa pou katoa.

Te ōritetanga ā-mīhini:Kāore i rite kiNgā puranga momo-Z,te wāhanga whakawhiti takitahi o tePuranga-Uhe tino ōrite. Mā tēnei ka tino ōrite te tohatoha o te ahotea o roto ina pāngia e te pēhanga whenua taha, te pēhanga wai rānei, ka māmā ake ai ngā tauira tatau hanganga.

Te Wāhanga Āhuakore me te Tauwehenga Wāhanga:

Tukanga Hurihuri Wera: Ngā puranga āhua-U kua hurihia wera(pērā i te momo Larssen) ka hangaia mā te hurihuri pāmahana teitei, ka hua ake he tohatoha matotoru pūtaiao ake o ngā flanges me te tukutuku. Mā tēnei ka taea te whakaputa i tētahi modulus wāhanga tino teitei (mai i te 745 cm³/m ki te 3,200 cm³/m) me te pupuri tonu i te taumaha waeine iti.

Tātai Tātaitanga:Taumahatanga Piko sigma = M / W, ko M te wā piko, ā, ko W te modulus wāhanga. Ko te uara-W teitei o ngā pou-U te mea e whakatau tika ana i tō rātou ātete hurihuri ina whakamahia i roto i ngā tāwharau.

Te Hononga me te Ārai Wai

Te Hononga a Larssen:He tino tika te hanga o ēnei hononga raka. I te tau 2026, he tohunga hangarau moana,ngā hiri whānuie whakamahia ana i mua i roto i ngā hononga.

Te Mātāpono Ārai Wai:Kia oti te pana, ko te piri o ngā hononga raka ehara i te mea ka whakawhiti noa i ngā kaha kutikuti engari ka whakaitihia hoki te pēhanga turuturu mā te whakanui ake i te roa o te ara turuturu. Mō ngā kaupapa waipēhi he nui ngā rerekētanga o te pane wai (pērā i ngā kaupapa tiaki wai i Philippines), ko te mahi hiri o ngā hononga raka huri-wera he nui ake i ngā pou matao-hanga.

Ngā Paerewa Hangarau o te Ao

I roto i te hokohoko ā-ao me te tuku tono kaupapa, e rua ngā pūnaha paerewa matua e whaihia ana:

Pūnaha Paerewa Te Whakaingoatanga Matua Ngā Wāhanga Hangarau
Paerewa Pākehā (EN) EN 10248 E whakaatu ana i te āhua, ngā ātete ā-ahu, me ngā āhuatanga hangarau o ngā puranga pepa maitai kore-koranu kua hurihia-wera. Ngā momo noa: S355GP, S430GP.
Paerewa Hapanihi (JIS) JIS A 5523/5528 E kapi ana i ngā momo pēnei i te SY295 me te SYW295, e aro ana ki te pakari o te maitai me te āheinga ki te whakarewa. He whānuitia te whakamahinga i ngā rohe ru whenua o te Tonga-mā-rāwhiti o Āhia me te Rim o te Moana-nui-a-Kiwa.

Ngā Auahatanga Hangarau o te tau 2026: Te Whakamamati me te Rino Kakariki

Aroturuki Hanganga AIKo te tāutanga pou-U hou ka whakauruhia ki ngā kāmera AI Human Factor Recognition (HFR) i runga i ngā papa pou hei aroturuki i te haumaru o te papa i te wā tonu, me te whakaputa aunoa i tētahi Driving Log e tuhi ana i te hohonutanga o te urunga o ia pou.

Rino KakarikiMō ngā kaupapa papai i Ūropi, Amerika, me Ahitereiria, kei te wātea inaianei ngā pou-U i hangaia mā te Electric Arc Furnace (EAF) me ngā tapuwae waro kua whakamanahia hei whakatutuki i ngā whakaritenga arotake tukunga waro.

Te Kaha-Teitei me te WhakamāmāMā te tāpiri i ngā huānga whakakoi-moroiti, kua noho te maitai Q355 hei paerewa, ā, kei te piki haere te rongonui o ngā pou kaha-tino Q420 i roto i ngā tautoko poka hohonu hei whakaiti i te paunga o te maitai.
