Nō nā tata nei, kua oti te huihui me te tirotiro i tētahi puranga o ngā ārai hau hau mō te tuku. Kei te wātea ēnei ārai i roto i ngā rahi DN150, DN200, DN300, DN400 me te DN600, ā, ka tukuna ēnei ārai i roto i ngā kōwhiringa tinana waro maitai me te kowiri tira mō ngā kaihoko o te ao e mahi ana i roto i ngā kaupapa hau ahumahi, te maimoatanga hau para, ngā paipa tuku wera me ngā kaupapa tango puehu whakarewa.

E mōhiotia ana hoki ko ngā ārai pūrerehua whakapūhau, kei tēnei raupapa he hanganga flanged kua whakauruhia me ngā kaiwhakaoho hau hei tautoko i te whakaweto-mamao me te whakahaere rere. He tino pakari te tinana takirere me te hiri poutū kua whakapaitia hei whakaiti i te turuturu. He pai te ātete a ngā ārai hau kowiri tira ki te waikura me te ātete pāmahana teitei mō ngā āhuatanga hau haukū me te waikura, ko ngā putanga waro rino he mahi utu-pai mō ngā paipa kawe hau wera me te hau noa.

Ko ngā painga matua ko te kapi whānui mō ngā pūnaha paipa iti ki te rahi. Mā te whakaoho hau ka tere te urupare. Mā ngā takirere solenoid me ngā pana rohe e ōrite ana ka taea te whakauru ngāwari ki ngā pūnaha whakahaere aunoa. Mā te hononga flanged ka māmā ake te tāutanga me te tiaki i te papaanga. Mā te ātete rere iti ka tino pai te hauhautanga mō te whakaweto me te whakarerekētanga tonu o te rōrahi hau.

Ko ngā mea e tika ana ko te hau taiao, te hau wera, te hau paipa me te hau puehu. He whānuitia te whakamahinga i roto i te tango puehu whakarewa, te purenga hau para ahumahi, ngā paipa HVAC, ngā paipa tautoko tahunga para, te tohanga hau wera o te tipu sima me ngā pūnaha whakapūmau wai. Kei te wātea ngā rahi ritenga, ngā paninga ārai-waikura me ngā whakapainga pāmahana teitei hei whakatutuki i ngā paerewa kaupapa o te ao.

Ka whakamatautauria te piripono me te whakahaere o ia takirere whakakā i mua i te tukunga. E mahi ana mātou ki ngā kaimahi kirimana EPC o te ao, ngā kaihanga taputapu me ngā hoa hokohoko, e tuku ana i ngā pepa raraunga katoa, ngā tuhi me ngā otinga kua whakaritea.
