He rerekē ngā momo arawhata taura tuku iho i runga i ngā rauemi me ngā āhua, ia momo e hāngai ana ki ngā āhuatanga mahi motuhake. Ko te rauemi e whakamahia whānuitia ana ko te maitai hanganga waro noa Q235B, e mōhiotia ana mō tōna wātea, tōna utu iti, tōna āhuatanga miihini pumau, me tōna maimoatanga mata whai hua. Heoi, mā ngā āhuatanga mahi motuhake ka hiahiatia he rauemi rerekē.
Ko te rohenga hua o te rauemi Q235B he 235MPA, he iti te ihirangi waro me te pakari pai, he mea tino pai mō te tukatuka makariri, te piko, me te whakarewa. Mō ngā arawhata taura, he maha ngā wā ka pikohia ngā reera taha me ngā pae whakawhiti hei whakanui ake i te pakari, me te whakarewa i te nuinga o ngā hononga, kia pai ai mō ngā āhuatanga mahi rerekē.
Mō te ātete ki te waikura, ko te nuinga o ngā arawhata taura o waho he mea hanga ki te maitai ngawari, ā, ka tukuna he maimoatanga mata ki te konutea wera-tuku. Ko te hua o tēnei tukanga he paparanga konutea matotoru o te 50 ki te 80 μm, e whakarato ana i te tiaki waikura mō ngā tau neke atu i te 10 i roto i ngā taiao o waho noa. Mō ngā whakamahinga o roto, ko ngā arawhata taura konumohe te mea e pai ake ana nā te mea he ātete ki te waikura. He maha ngā wā ka tukuna ngā hua konumohe ki te maimoatanga waikura mata hei whakanui ake i te roa.
He nui ake te utu o ngā arawhata taura kowiri tira, pērā i te SS304, te SS316 rānei, engari he mea tika mō ngā taiao motuhake pērā i ngā kaipuke, ngā hōhipera, ngā taunga rererangi, me ngā whare hanga matū. Ko te SS316, he mea whakakikorua ki te nikara i muri i te hanga, he ātete pai ki te waikura mō ngā āhuatanga kino pērā i te pānga ki te wai moana. Hei tāpiri, ko ngā rauemi rerekē pērā i te kirihou kua whakapakarihia ki te muka karāhe ka whakamahia mō ngā kaupapa motuhake pērā i ngā pūnaha tiaki ahi huna, ko ia kōwhiringa rauemi i runga i ngā whakaritenga o te kaupapa.
Te māramatangangā purongo pakihiKo te tikanga o tēnei ko te mārama ki te pānga o ngā kōwhiringa rauemi i roto i te hanga me te hiranga o ngā maimoatanga mata hei whakarite i te roa me te mahi o te hua. I te whanaketanga o ngā ahumahi, ko te hiahia mō ngā arawhata taura i hangaia mō ngā āhuatanga rerekē kei te akiaki tonu i te auahatanga me te ahunga whakamua hangarau i roto i te mākete. Mā te tātari i ngā whakaritenga ahurei o ngā taiao rerekē ka taea te ārahi i ngā pakihi ki te whiriwhiri i ngā rauemi tino tika mō ā rātou kaupapa arawhata taura, ā, hei whakamutunga ka whakarei ake i te pai o te whakahaere me te roa o te ora.
