Nō nā tata nei, he puranga o ngā taputapu ā-ringa me ngā taputapu hikongā takirere kēti maripikua oti pai te whakatuwheratanga me te katinga katoa i roto i te awheawhe, ā, ka tukuna wawetia ki ngā kaupapa hangarau o tāwāhi. Ko ngā whakatakotoranga e wātea ana ko DN150, DN200 me DN300. I hangaia me te pēhanga ingoa PN10, ka mau tonu ngā pāmahana mahi tae atu ki te 80°C, ā, he mea hanga motuhake mō te reo wai i roto i ngā pūnaha paipa.

He hanganga kiato te takirere kēti maripi, he rerenga tika tonu, kāore he rohe mate. He mea hanga tōna tinana mai i te rino ngāwari kounga teitei mā te whakarewa tika, e whakarato ana i te pakari o te hanganga me te ātete pānga i raro i te pēhanga paipa tikanga. He ātete pai te pereti kēti kowiri tira ki te kakahu me te waikura, e whakarite ana i te iti o te taipana mahi i ngā huringa pana maha. Mā te hoahoa nohoanga rapa kua arotauhia ka tukuna he kati pono me te piri kia kore ai e turuturu waenga, ahakoa i raro i te pēhanga mahi katoa, i raro rānei i te pēhanga mahi wāhanga.

E rua ngā whirihoranga whakaoho e tukuna ana hei whakatutuki i ngā tono kanorau o te papaanga. Ko te putanga ā-ringa he wira ringaringa kua whakanuia, e āhei ai te whakahaere ā-ringa ngāwari i te papaanga mō ngā paipa iti me ngā teihana tirotiro auau. Ka taea te whakauru i te putanga hiko ki ngā whakaoho hiko ātete-pahū hei whakatutuki i te whakahaere whakatuwheratanga me te kati aunoa mamao.

Ka whakahaerehia te mana kounga puta noa i te tukanga hanga katoa. Ka whakamatautauria ia takirere takitahi i mua i te wehenga atu i te wheketere. Ka tirotirohia katoatia e ā mātou tohunga hangarau te ngāwari o te mahi, te pono o te hiri me te taunga o ngā wāhanga, ka whakakorea pai ngā hapa noa pēnei i te aukati pereti, te turuturu o roto me te rahunga o te whakaoho i te wā roa o te ratonga tonu.

Ki te whakatauritea ki ngā takirere keti poro tuku iho, he tino angiangi te matotoru o te tinana o ngā takirere keti maripi, e whakaiti ana i te wāhi tāutanga e hiahiatia ana, e whakapoto ana hoki i ngā wā hanga mō ngā pūnaha paipa hou me ngā pūnaha paipa kua whakahoutia. Mā te hanganga o roto māmā ka whakaiti i te uaua o te tiaki noa; ka taea e ngā kaiwhakahaere te whakaoti i te tirotiro i te papaanga me te whakakapinga wāhanga mau me te kore e wetewete i te takirere katoa mai i ngā paipa, ka whakaiti nui i ngā utu whakahaere mō te wā roa mō ngā kaipupuri rawa.

Ka whakamahia e tēnei raupapa o ngā takirere kēti maripi he hononga hononga wafer paerewa, e hototahi ana ki ngā paerewa flange paipa matua o te ao, he watea hoki mō te tāutanga kaupapa o te ao. He whānuitia te whakamahi mō te whakahaere whakaweto me te whakaweto i roto i ngā whatunga tuku wai me te rerenga wai o te tāone, ngā tipu maimoatanga waipara o te tāone, ngā pūnaha wai rere ā-umanga, ngā whakaurunga rere wai pāka me te hanganga hangarau waipēhi.

Ka whakaratohia e mātou he ratonga whakaritenga ngāwari ki ngā hoa mahi o te ao. Haunga ngā rahi paerewa DN150, DN200 me te DN300, ka taea e mātou te whakarerekē i ngā rauemi tinana, ngā rauemi hiri me ngā momo actuator kia rite ki ngā tikanga mahi motuhake. Ka pupuri mātou i te kaha whakaputa pumau, ngā paerewa whakamātautau tino pakari me te tautoko whai muri i te hoko katoa mō ngā kaimahi miihini o te ao, ngā kaiwhakauru pūnaha maimoatanga wai me ngā kaituku paipa. Ko tā mātou whāinga he whakarato i ngā otinga whakahaere wai pumau, utu-pai e rite ana ki ngā kaupapa maimoatanga wai me ngā hanganga ā-tāone puta noa i te ao.
