Kei te hiahia koe ki te ako me pēhea te hangarau ERW e whakarite ai i te hanga kounga teitei?
Tūhurahia te whai huatanga o ngā mira paipa ERW i tēnei rā!
Ka hangaia e te mira paipa ERW ngā paipa kounga teitei mā te whakamahi i ngā hangarau matatau. Ka whakaputa pai i ngā paipa mā te hanga i ngā koiri wera-hurihuri kia rite ki ngā āhua porotaka me te whakarewa i ngā hononga. Tūhurahia te tika me te pono o ngā paipa ERW mō ō hiahia ahumahi i tēnei rā.
Kimihia ngā otinga pono mō ō hiahia hanga paipa.
He tukanga tino whakarite te hanga i tētahi paipa ERW tino tika. Anei te huarahi e oti ai te mahi a ā mātou mira paipa ERW matatau:
Te Wetewete me te Whakatakotoranga: Ka tīmata te haerenga me tētahi koiri rino nui, kua hurihia kia wera. Ka utaina tēnei koiri ki runga i tētahi wetewete koiri, ā, ka whāngaihia te rīpene rino ki roto i tētahi taputapu whakataurite hei tango i te huinga koiri, kia tino papatahi ai mō te tukanga hanga.
Te Whakarewa me te Whakarewa Mutunga: Hei whakarite i te mahi tonu, me te kore e mutu, ka kutikutia te pito hiku o tētahi koiri ka whakapirihia ki te pito matua o te koiri e whai ake nei. Mā tēnei ka hangaia he aho maitai kotahi, mutunga kore.
Wāhanga Hanga: Kātahi ka uru te rīpene papatahi ki te wāhanga hanga. I konei, ka piko haeretia te rīpene e ngā roera kua whakaritea kia tika, kia rite ki te ngongo porowhita, tuwhera te hononga. He mahi nui tā ia tūnga roera ki te hanga i te ngongo ki te diameter e hiahiatia ana.
Whakarewa Auau-Teitei: Koinei te ngako o te tukanga ERW. Ka whakauruhia he iahiko hiko kaha e te koiri whakapūmau auau-teitei, e ngā pito whakapā rānei, ki ngā taha o te ngongo tuwhera. Ka tere te whakamahana o te iahiko i ngā taha ki te pāmahana whakarewa (neke atu i te 1200°C). I taua wā tonu, ka pēhia ngā taha rewa e te huinga roera pēhi, ka hangaia hei hononga pumau, tino-pūmau.
Te Maimoatanga me te Whakamatao Tuitui: Whai muri i te whakarewa, ka tangohia ngā rauemi taikaha katoa i waho me roto o te tuitui whakarewa (e mōhiotia ana ko te uira) mā ngā taputapu tapahi motuhake kia maeneene ai te mata. Kātahi ka haere te paipa mā roto i tētahi wāhanga whakamatao ka rehuhia ki te wai whakamatao hei whakaiti i tōna pāmahana me te whakau i tōna hanganga whakarewa.
Te Rahi me te Whakatikatika: Ka neke te paipa kua whakamataotia mā roto i tētahi wāhanga rahi, ka whakarite tētahi atu huinga roera kia tutuki te diameter o waho whakamutunga ki ngā ātete rahinga tika. Kātahi ka whakarite he mīhini whakatikatika kia tino tika te paipa.
NDT me te Tapahi: Hei whakamutunga, ka tirotirohia ia inihi o te hononga whakarewa i te wā tonu mā ngā taputapu Whakamātautau Kore-Whakangaro (NDT), pērā i te taputapu whakamātautau au hurihuri, kia kitea ai ngā hapa pea. Kia oti te whakakore, ka tapahia e te kani rere tere te paipa tonu ki ngā roa kua whakaritea i mua, me te kore e aukati i te raina whakaputa.
