He mea nui te tūranga o ngā paipa maitai tui kore i roto i te ahumahi hou, ā, e whakamahia whānuitia ana i roto i te hanganga, te hanga mīhini, te hinu matū me ētahi atu mara.EN 10210e tohu ana i ngā paipa maitai kore-hono mō ngā hanganga, ā, ko te BS EN 10210-1 he whakatakotoranga motuhake mō ngā maitai hanganga kore-koranu kua hurihia wera-wera me ngā maitai hanganga kikokore. Ko ngā tohu noa i roto i tēnei paerewa ko te S235GRH, S275JOH, S275J2H, S355JOH me te S355J2H.

Tuatahi, he maitai kounga taketake te S235GRH, e whakamahia ana mō ngā wāhanga hanganga i raro i te ahotea iti me te pāmahana rūma. Me te kaha whakaputa o te 235MPa, he pai te kaha ki te whakarewa me te hanga matao, ā, he pai mō te hanganga whānui me ngā hanganga miihini.

Ko S275JOH me S275J2H te mea e whai ake nei. He pakari te S275JOH i te -20℃, ā, ko te kaha whakaputa he 275MPa, ā, e whakamahia ana mō ngā hanganga hanga me ngā kaupapa piriti me ngā kawenga reo. He pakari ake te S275J2H i te -20℃, ā, he pai mō ngā wāhanga hanganga e hiahia ana ki te tauwehe haumaru teitei ake.

S355JOHmeS355J2HHe maitai kaha-teitei ngā maitai. He tino pakari te S355JOH i te pāmahana rūma me te pāmahana iti (-20℃), me te kaha whakaputa o te 355MPa, ā, e whakamahia whānuitia ana i roto i ngā kaupapa hanganga ahotea-nui me ngā kaupapa hanganga nui, pērā i ngā whare teitei me ngā piriti nui. He kaha ake te pakari pānga o te S355J2H i te -20℃, ā, he pai mō ngā wāhi tino makariri, ngā kaupapa rānei e hiahia ana ki te whakapumautanga haumaru tāpiri.

Ehara i te mea ko te paerewa EN 10210 anake e whakamārama ana i te hanganga matū me ngā āhuatanga hangarau o ngā paipa rino, engari e whakatakoto ana hoki i ngā whakaritenga motuhake mō ngā ātete ā-ahu, te kounga o te mata, te whakamātautau kore-whakangaro, me ētahi atu. Mā tēnei ka whakarite i te ōritetanga me te pono o ngā paipa rino i te wā e hangaia ana, e whakamahia ana hoki.

Ka hangaia ngā paipa maitai kore hononga mā te hangarau hurihuri wera, ka homai he āhuatanga miihini tino pai me te tika o ngā āhuatanga. Ka taea e te tukanga hurihuri wera te whakakore i te ahotea i roto i te paipa maitai, te whakapai ake i te hanganga whakahaere o te maitai, me te whakarei ake i tana mahi whānui. Ki te whakatauritea ki ngā paipa maitai kua whakarewaina, he nui ake te kaha o ngā paipa maitai kore hononga ki te pēhi, te piko me te hurihuri, ā, he pai mō te tautoko hanganga me te kawe wai i raro i ngā āhuatanga mahi uaua.

I te nuinga o te wā, ko ngā paipa maitai kore hononga i hangaia kia rite ki ngā paerewa EN 10210 e whakaatu ana i te mahi tino pai i roto i ngā mara hanga me ngā mara ahumahi. He āhuatanga motuhake ō ngā paipa maitai o ngā momo pēnei i te S235GRH, S275JOH, S275J2H, S355JOH, me te S355J2H, ā, ka taea te whakatutuki i ngā hiahia o ngā kaupapa rerekē. Ehara i te mea ka whakapai ake i te kounga me te haumaru o ngā kaupapa anake te whakamahinga whānui, engari ka whakatairanga hoki i te whanaketanga me te auahatanga o te hangarau rauemi maitai. He mea nui te whiriwhiri i ngā paipa maitai kore hononga o ngā momo me ngā whakaritenga e tika ana hei whakarite i te pumau mō te wā roa me ngā painga ōhanga o ngā kaupapa.
