Kei roto i ngā ture mō te whai wāhi ki te mahi i ngā puipui ākau me ngā puipui ākau kōwhiri rite o ASTM A252. I kite au i runga i te taha o te pae, ko ngā pūtētē ākau e whakatetehia ana ki te whenua papa hei pūtake mō ngā whare, ngā hīkoi ara rori rānei. Ko tēnā he momo ture mō te mahi hanga e tohu ana i te mataku me te haumaru kia tutuki ai mō ngā puipui ākau. He aha ngā mea hou me ngā āhuatanga e whakaatu ana e te ASTM mō ngā puipui ākau A252? E whakaatu ana ia i te āheinga o ngā puipui, ā, me pēhea e whakatatūtia ana ngā puipui i te whakapuaki. He pai hoki hei whakamārama i te roa o te puipu; ā, me pēhea e whakaatu ana i te wā e hiahiatia ana te iti nui o te puipu.
Nō reira, tētahi o ngā take nui rawa ko te mea kua tango ia i te whanaketanga pūmau me te mea he maha ngā taenga o te tuara whenua, e whai ana ngā pū whenua aota ki te wā. He nui ngā whiuaro whakamana i ngā pū aota e hanga ana i te ASTM A252, kia āhei ai rātau ki te whakamahi i runga i te kauwae tai. Nā te mea ka whakamahia anō ngā pū iwi hei pūtake matatū mō ngā hanganga, nā te mea kua hokohoko ngā whare whakahoro. E hiahiatia ana e rātau te tono nui me te kore whakarereke... rānei te kore whakapakaru i te wā. Tērā pea ka whakatika mai i tēnei, nā te take tuatahitia, ko te mea nui hei whakarite i ngā wharewhare matatū mō ēnei mahi hanga.
Ka whakamana ia i te mea he rite ngā huamahi ki uta ki tai hei whai i te haumaru, ā, ka whakaae he mīhini pai noa iho e mahi ai i ngā ture ASTM A252. Hei tauira, i tēnei ture, kei reira ngā mīhini me ngā momo hanga kia whakamahia mo te tirohanga i ngā pīpu, e whakaatu ana i te paetae 6.2 o te ISO15609-1. Ko te tino matihiko ka taea e ngā hangaenga e hoki atu nei ki enei pīpu hei whakamahi mo ngā tono nui, pērā i te whakatū ake i ngā pōhutukawa me ngā whare, ko te whakapiki i te hopu whenua i raro i ngā oneone. Kei a matou te hiahia kia puta mai i tēnei tikanga he whakahaere pai ake, me ngā whare wawe tonu mo ngā rōpū hanga.
I te wā e hanga ana i te kāinga, me whiriwhiria ngā momo pīpu ASTM A252 tōtika, ā, me tiakina he wāhi nui kei te noho pai ai tō whare. Ka whai take nui tēnei whakatau ki ngā hua me te roa o tō kaupapa. He nuinga ā-mutunga ngā momo pīpu ASTM A252, ā, ina ia momo e taea ana te whakamahi mo ētahi whenua āhuatia. Mo ngā whenua he iti raweke me ngā huringa iti, ko te rārangi 3 o te ASTM A252 te whakaae tika. Ko te ASTM A642 Rārangi 3 hoki he rangatira me te mahi pai rawa i ngā wāhi hanga nui, nā runga i tana mohiotanga nui, ā, ko te ASTMA639 Rārangi 2 e pai rawa ana mo te tuānga pīpu i ngā whenua pono, engari me ngā pīpu nui e taea ana te whakapakiti hei whakatū mai i te haere pai.
Kua whakauru nei ngā Pīpi Whakatetonga A252 o te Ao Matihiko ASTM, e taea ana hei whakatika mō te nuinga o ngā pūtango whakaako hoki i whakamahia i roto i ngā Pūtanga Whare, te Whakatū Rāhui me ngā Wāhi Whakarite, ā, ina whai hua ngā whare rānei, ngā tāhuhu rānei. Ko te rangatiratanga me te whai wātea o ēnei pīpi whakatetonga te take i heke ai ngā mahi hanga whenua ki a rātau i runga i ngā tūtohu kē, pērā i te konakona rānei, te aporo rānei. Mā te whakahokia anō hoki o ngā pīpi aho, ka whakaora i a tātou māungāwhenua. Ko ngā whatunga e taea te whakahoki, ko te take i a ngā hanga ki te whakatika i te tiaki i ngā whare o tenei rā.
Ko tō tautohetohe ko te tau e rua tekau ma rua o ngā tau i te mahi i te whakahē rautahi, ka taea e tātou te tuku mai i ētahi atu rara me ngā whatunga. Kei a tātou hoki he takiwā o ngā kaiwhakawhiwhi take moeao i te ao, me te whakarite ara pai, ka tukuna mai ki a koe ngā whakaaetanga me ngā tautoko e pai rawa. E ai ki te nui o ō hokohoko, e ai ki te iti noa iho te utu!
Kei a tātou ngā tohunga mō te timatanga whirinaki astm a252 me te whakamahere ā-waro hoki, ngā whakahoa ki te wā e tū mai ana, me te ratonga matua. Kei a tātou anō he kaimahi whirinaki mō te paihikara hei tirotiro i ngā tono mō ngā pūtea 24 rā o te wiki hei whakautu i ngā pātai, tono, whakataunga, me ngā hiahia. Kia uaua au ki te whakapono ko tātou e hangaia nei he hoa mahi whakapono ki a koe.
Taea noa atu e tātou te tuku i ngā tahuhu H i te paetukutuku Amerika/Ripēni/Arāhina, me ngā tahuhu ā-mātāwaka o te Kīngitanga Nihon astm a252, ā, ka taea hoki e tātou ngā ratonga whakarerekē pērā i te kaweke me te tapa. Ki te tae rawa ki tenei wā, kua hokona ngā mahi o tātou ki te Uruwhenua ki te Rāropuke, ki te Tawhiti Taihou, ki te Moana-roa, ki te Afrika, ki te Waipū me etahi atu rohe.
Ka tirotiro ia ia raupapa i mua i te whakaputu. Te mana o te pai taunaki. Nā te mea nui ko ngā raupapa katoa, astm a252/SSAW/LSAW/ me te rorohiko/gawhe tika/me te raupapa kore-kai-tū/me te raupapa porotētini), ngā tohu (taumata Amerika, taumata Rīti, taumata Āhina H-beam tera), ngā niho tera, Niho pūnaha, niho whakarara, niho whakatetonga, ngā niho o ētahi atu tikanga me ngā niho rorohiko, niho rauemi, tākaro, niho tāwera, tāpapa tera, tāpapa whakarara, ngā tāpapa o ētahi atu tikanga, me ngā tāpapa rorohiko.
