Ko te BS EN 10210 S355J0H, nama maitai 1.0547, nō te wāhanga maitai hanganga tuwhera wera, ā, ka taea te hanga hei paipa maitai tui, hei paipa whakarewa rānei, e whakamahia ana i roto i ngā hanganga e hiahia ana kia kaha te hanga me te pakari pai, pērā i ngā anga whare nui me ngā piriti.
Ko ngā āhuatanga ā-ringa o te rauemi S355J0H ko te kaha whakaputa iti rawa ko te 355MPa ina kore te matotoru o te pakitara e neke ake i te 16 mm, ā, ka tutuki i te kaha pānga iti rawa o te 27J i te 0℃.
Kei roto i te BS EN 10210 he whānuitanga o ngā āhua whakawhiti-wāhanga, pērā i te porowhita, te tapawhā, te tapawhā hāngai, te porowhita rānei. He tohunga a Botop Steel ki ngā ngongo maitai porowhita o ngā rahi rerekē, e whakarato ana i ngā rauemi ngongo maitai kounga teitei, e tutuki ana i ngā paerewa, me te hoko tika mai i te wheketere me te utu whakataetae.
Kia mōhio: Ka pā hoki ngā whakaritenga katoa o tēnei tuhinga ki te EN 10210.
Te matotoru o te pakitara ≤120mm.
Porowhita (HFCHS): Ngā diameter o waho tae atu ki te 2500 mm;
Tapawhā (HFRHS): Ngā rahinga o waho tae atu ki te 800 mm x 800 mm;
Tapawhā hāngai (HFRHS): Ngā rahinga o waho tae atu ki te 750 mm x 500 mm;
Porowhita (HFEHS): Ngā rahinga o waho tae atu ki te 500 mm x 250 mm.

Ko ngā tohu rauemi i roto i te BS EN 10210 e ahu mai ana i tōna kaha tuku iti rawa i te matotoru o te pakitara 16mm me ngā āhuatanga pānga i ngā pāmahana motuhake. Ka heke te kaha tuku, te kaha kume, me te roa o te BS EN 10210 S355J0H i te pikinga ake o te matotoru o te pakitara.
Mā te BS EN 10210 ka taea te whakaputa mā te whakamahi i ngā momo tukanga hanga, tae atu ki ngā tukanga whakarewa tuturu, LSAW, SSAW, me te ERW.
Kei raro nei te whānuitanga o ngā rahi mō ngā tukanga whakaputa noa.
Mai i te whakataurite i runga ake nei, ka kitea he painga ā-roto tō te paipa maitai kore-hono i roto i te hanga paipa maitai matotoru-taiepa, inā koa he paipa maitai matotoru-taiepa iti te whānui, engari he iti noa iho tōna rahi. Mēnā me hanga paipa maitai neke atu i te 660mm te whānui, ka uaua ake.
Paipa Pango
E pā ana tēnei ki te paipa rino kāore he maimoatanga mata.
Paninga Parenga Rangitahi
Hei ārai i te waikura o ngā paipa rino i te wā e rongoatia ana, e kawehia ana, e tāutahia ana rānei, ko tētahi tikanga noa ko te pania o te mata o te paipa ki tētahi paparanga peita, ki tētahi wanihi rānei.
Paninga Ārai-waikura
He maha ngā momo paninga ārai-waikura, tae atu ki te peita, te FBE,3LPE, me te konukōre. He āhuatanga motuhake tō ia momo paninga me ngā taiao e tika ana. Ka taea te ārai pai i te waikura me te waikura mā te pani i tētahi paninga ārai-waikura e tika ana ki ngā mata maitai.
Me tutuki ngā paninga konukōre wera i runga i ngā mata paipa rino i ngā whakaritenga e tika ana o te EN ISO 1461.

Ko te teitei o te hononga whakarewa ātete kāore e toro atu i tua atu i te mata o te paipa, ā, i te wā e hangaia ana, ka mahia te hononga whakarewa kia rite tonu ki te mata o te paipa, ā, kia kore ai e kitea.
E whakamahia whānuitia ana te BS EN 10210 S355J0H i roto i ngā hanganga whare, te hanga mīhini, ngā paipa kawe waka, te hanga hanganga, ngā kaipuke, me te hangarau moana. Nā tōna kaha me tōna pakari pai, he mea tino pai mō ngā kaupapa pēnei i ngā piriti, ngā whare teitei, ngā whare ahumahi, ngā kerēni, ngā paipa hinu me te hau, me ngā pourewa hiko hau.
