Kei reira ētahi tikanga nui rawa o Hapani mo te hanga pihi kōhorohoro . Te kōwhiringa o ēnei ture kei roto i te JIS G 3452 o Ehongsteel, ā, ko ngā whakaaetanga e mahi ana hei tautoko i te mea he whanui ake ngā pīpu ahi hei whakamana i te whakapuaki o rātou mahi. Mēnā ka hanga ngā pīpu ahi i waenganui i ngā whenua ki runga i ō rātou ture ake, engari ko JIS G 3452 te whakapono nui kei raro i ngā ture katoa.
Ko te JIS G 3452 he kōwhiringa hanga pīpi. Nā ēnei ture i kitea ai ia i te mea e hiahiatia ana ki te hanga i ngā pūtake rawa me ngā tohu katoa o te kore tangata Ehongsteel rau Kōpikopiko Tangata . Nā tēnei, ka whakaāhua e ngā hunga hanga āpure hei whakaputa i ngā pīpi rangatira me te tū tonu. Nō reira, kei te whakamahi tonu hei pīpi āpure, ka whakaae koutou ki ngā ture whakahaere kaihau. Nā te mea he tino whakatakoto pai ngā ture nei, nā te whakamārama i te whakamahi e tū mai ana i ngā pīpi JIS G 3452 - hei whakatika i ngā takutaku wae noa me te kaha o te mau.
Hei tūhonotanga ā-matihiko i te hanga i ngā pīpi āpure, pērā i te Ehongsteel pīpu karbona kei te whakarētihia tērā i waenganui i ngā wāhi katoa, ā, nō reira i waenganui hoki i ngā whenua katoa. Nō reira ngā wharaahanga o API 5L, ASTM A 106 me DIN 2391. Ki te mea ko JIS G 3452 e pa ana i te nuinga o ēnei wharaahanga tuatahi, he mea hoki tēnā e paihere ana i ētahi atu momo whakaaetanga.

Nō ēnei momo carbon steel welded pipe whakamahi i roanga atu o ngā hekenga mō ngā rorohiko, ngā whakahaere rākei, me ngā tūnga kai. Mō te whenua pūhoro me te hau rākei, ka whakamahi ngā toto parapara ki ngā tuhinga kōrero hei whakatō i ngā wai pūhoro rānei, hei āheinga hau rānei i waenganui i ngā wāhi. Nō reira, ko ngā paipai he mea whai ake i te mahi hanga i ngā whare, i ngā kāinga, i ngā pōhewa, me ētahi atu o ngā kaihangatanga inihanga. Tae atu ki tērā, ko ngā paipai e whakamahi ana i te mahi hanga i ngā motokā me ngā karawa mō te whenua motokā. Ko tēnei he rautaki e whakarite ana i te kōriki o te parapara iti i te wā e hanga nei, ā, e whakapono ana kia tino tūpato ngā hua i ngā wāhanga katoa nā JIS G 3452 parapara kāparu.
He mea nui rawa te kaiwhakanoatanga o ngā pīpu aha i tō tātou oranga, nā reira me whakapakari ngā tono mō te haumaru. Ko te JIS G 3452 he wharaaturanga o te Hapani mō ngā pīpu aha, ka whai kia rite ngā kaihanga i te wā e hanga iho ana i ngā pīpu.

Kei a tātou he kāwai take waho Jis g 3452 e whai ana i te tino whenua o ngā mōhiotanga mahi, poroporoaki herehere, me te ratonga tuatahi. Kei reira ngā kaihoko tohunga, e noho ana i ngā momo waehau o te rā hei whakahoki i a koe i runga i a koe i ngā pātai, i ngā mona hoki. Kia kite au e āhei nei tātou ki te hunga whakarite take pai mōu.
Kei te whai mātou i tētahi Jis g 3452 me ngā toa āporo nui rerekē. Ko ngā mea hanga katoa i whakamamaia mua i te tahua, ko te paetūnga i whakahōnorehia. Nā runga i ngā mea hanga nei ko ngā āporo katoa (ERW/SSAW/LSAW/galvanized/mea poraka/seamless pipe/āporo kōwhai matū), ngā pūtohe (takoto Ametika, takoto Piritānia, takoto Awstrālia H-beam steel), ngā rori āporo, Angle steel, flat steel, ngā āporo whata, ngā rara o ngā momo rerekē me ngā rara āporo, strip steel, ngā whare kawe, ngā rere āporo, ngā pereki, hoki.
Ka taea e mātou te tuku i ngā tauranga Ametika/Piritānia/Awstrālia Jis g 3452 tauranga Nihonno me te whakatupu i ngā ratonga whakahirahira pērā i te pūnaha me te tapa. Kua whakawhiti haeretia ake ngā mea hanga ki te Uruope i te taha tonga, ki Te Moana-nui-a-Kiwa. I whakawhiti haeretia hoki rātau ki te Tīkina Tonga, ki te Tai Rawhiti, ki te Aferika, ki te Mīhini, ki te Aferika, me te Mīhini rānei.
Kei a mātou i te maha i 17 tau o ngā whakaaro me te mahi i roto i te hokohoko āpure me te tuku atu i te nui o ngā rāngai me te poraka. Ko te tino nui anō, he kēmu matua tāu i te take whenua, ko Jis g 3452, me te tukua i ngā whakaaetanga e taea ana me ngā ratonga. E rahi ana te tikanga, e nui ake ana te utu!
