Mena kei te hiahia koe ki te mōhio atu ki ētahi atu kōrero, pēnei i te whakatau utu, ngā hua, ngā otinga, me ētahi atu, prīhiwhakapā mai ki a mātou i runga ipurangi.
He toa hokohoko a Tianjin Sanon Steel Pipe Co., Ltd. Kei te Tāone o Cangzhou, Porowini o Hebei tō mātou wheketere. Ko ā mātou puna matua o ngā taonga kongā paipa kōhua, ā, ko ngā rauemi e whakaatu ana i tēnei koASTM A335 P5/P11/P91/P92,ASME SA-106/SA-106MGR.B,GB/T 3087-200810#/20#. Ko ngā rauemi matua mō ngā paipa paipa koAPI 5L,API 5CT, ngā rauemi matua mō ngā paipa pakaru hinuGB/T 9948he 15MoG/12CrMoVGKo te GB/T 6479-2013 e tohu ana i ngā rauemi 10#/20#, ngā ngongo whakawhiti wera SA179/SA210/SA192, me ētahi atu. Ko ngā ngongo miihini GB/T 8162 e tohu ana i ngā rauemi 10#/20#/Q345/42CrMo, ko te EN10210 e tohu ana i ngā rauemi S355JOH/S355J2H, ko ngā ngongo rango hau GB1 8248 e tohu ana i ngā rauemi 34CrMo4/30CrMo.
Ko te EN 10210 he paerewa nui a Ūropi e whakaatu ana i ngā tikanga tuku hangarau mō ngā wāhanga hanganga tuwhera kua oti te whakamahana i hangaia mai i ngā maitai kore-koranu me ngā maitai pai-kiko. Kāore i rite ki ngā wāhanga hanga-matao (EN 10219), ka hangaia ngā ngongo tapawhā EN 10210 mā roto i ngā tukanga hanga-wera (hei tauira, te whakaputanga, te huri wera rānei), e hua ake ai he āhuatanga miihini ōrite ake, he pai ake te kaha whakarewa, me te whakaiti i ngā ahotea toenga. Nā ēnei āhuatanga ka waiho hei whiringa pai mō ngā tono mahi taumaha maha i Ūropi.
1. Te Hanganga me te Hangarau Ā-Iwi
I Ūropi, e whakamahia whānuitia ana ngā ngongo tapawhā EN 10210 i roto i ngā anga maitai e mau ana i te kawenga mō ngā whare arumoni, ngā papa tākaro, me ngā piriti. Nā te āhua wera o te whakaotinga ka tino pakari i ngā pāmahana iti, he mea nui tēnei mō ngā rohe Nordic me Alpine. He maha ngā kaihoahoa e pai ake ana ki ngā kokonga koi, ma o ēnei wāhanga mō ngā wāhanga hanganga e kitea ana (hei tauira, ngā pou me ngā taura) me noho tahi te ataahua me te kaha.
2. Te Hangarau Mīhini me te Hangarau Tipu
Ka whakamahia e ngā kaihanga mīhini Pākehā ngā ngongo tapawhā EN 10210 mō ngā anga pakari o ngā mīhini perehi ahumahi, ngā kaikawe, me ngā wāhanga kerēni. Mā ngā āhuatanga pānga kua whakamanahia o te paerewa (hei tauira, i te 0°C, i te -20°C rānei) ka taea e ēnei mīhini te mahi pono i roto i ngā wheketere kāore i whakamahanatia, i ngā taiao o waho rānei.
3. Ngā Hanganga me ngā Mahi Tūmatanui
Kei roto i ngā whakamahinga ko ngā arai tohu, ngā pou rama, me ngā tautoko ārai haruru i ngā huarahi tere me ngā rēriwe. Ka whakarato te tukanga whakaoti-wera i te ātete tino pai ki te ngenge, he mea nui mō ngā hanganga e pāngia ana e ngā kawenga hihiri pēnei i te hau, i ngā wiri rānei i puta mai i te waka.
4. Ngā Taiao o te Moana me te Moana
Ahakoa ehara i te mea hei whakakapi mō ngā momo ātete-waikura,Ngā ngongo tapawhā EN 10210i roto i te maitai angiangi (hei tauira,S355J2H(S420MH rānei) e whakamahia ana mō ngā ara hīkoi papaaho, ngā papa taunga rererangi, me ngā wāhanga o te tauranga i ngā rohe o te Moana-a-Kiwa me te Moana-nui-a-Kiwa. Nā te matotoru o te pakitara me te korenga o ngā ahotea o roto ka whakaiti i te tūponotanga o te pakarukaru i ngā āhuatanga makariri, tote.
5. Ngā Pūnaha Tiaki Ahi me te Haumaru
He maha ngā wā ka whakauruhia ngā ngongo tapawhā kua oti te whakamahana mai i te EN 10210 ki roto i ngā waeine whare ātete ahi nā te mea ka taea e ō rātou āhuatanga rauemi te whakarite kia matapaetia te whanonga i raro i ngā pāmahana teitei. Ka whakamahia hoki ēnei mō ngā hanganga whakawātea me ngā arai haumaru.
Ngā Tohu Rino Matua:
S235JRH,S275J2H, S355J2H, S420MH, S460NH – me ngā whakamātautau pānga i raro i te kore-kore e hiahiatia ana mō ngā kaupapa Pākehā.
He aha i pai ake ai te EN 10210 i Ūropi:
Te Whakatutuki i ngā Ture mō ngā Hua Hanga (CPR)
Te whai mana ki te tohu CE
Hototahi ki te Eurocode 3 (EN 1993-1-1)
He āheinga whakarewa kua whakamanahia, kāore he whakamahana mō ngā matotoru noa
