I te hoahoa tuatahi o tePaipa PPR, ka whakaarohia ngā mea tino nui e toru, arā, ko te roa o te ora o te paipa, te pāmahana whakahaere me te pēhanga whakahaere. Ka pāngia ēnei mea e toru, nō reira me tutuki ngā tawhā i ngā whakaritenga kua tohua.

Ko te uara pēhanga ePaipa PPRka taea te tu atu me whakawhirinaki ki te roa o te hoahoa o te paipa me te pāmahana i roto i te taiao mahi hei whakaritenga matua.

I runga i ngā tawhā e toru o te roa o te ora, te pāmahana me te pēhanga, ka taea e tātou te whakatau i ngā ture e rua:

1. Mena ka whakaritea te roanga mahi toharite o te paipa PPR kia 50 tau, ka teitei ake te pāmahana o te taiao mahi o te paipa kua hoahoatia, ka iti ake te pēhanga mahi tonu ka taea e te PPR te tu atu, ā, ka pērā anō hoki.

2. Mena ka neke ake te pāmahana hoahoa o te paipa PPR i te 70℃, ka tino whakaitihia te wā mahi me te pēhanga mahi tonu o te paipa PPR. Nā te pai o te mahi a ngā paipa PPR i raro i te 70°C, ka noho ko ngā paipa PPR te mea tino rongonui mō te wera me te makariri.ngā paipa wai, nā te mea kei raro iho i te 70°C te pāmahana whānui o te wai wera o te whare.

E rua ngā momo paipa PPR: he paipa wai matao, he paipa wai wera. He aha te rerekētanga?

He angiangi ngā paipa wai matao. Ina hoki, he mea pai kia hokona ngā paipa wai wera katoa, nā te mea he matotoru te pakitara o ngā paipa wai wera, ā, he pai te ātete ki te pēhanga. E rua ngā momo whare whānui: 6 kei te pupuri i te hiko (25 mm te whānui o waho) me 4 kei te pupuri i te hiko (20 mm te whānui o waho).

Mena kei te papa iti koe e noho ana, ā, he teitei te pēhanga wai, ka taea e koe te whakamahi i tētahi paipa matotoru e ono ngā ira, kia nui ai te rere o te wai, kia kore ai e tino tere. Mena kei te papa teitei koe e noho ana, pērā i te rangatira kua whakahuatia ake nei, e noho ana i te papa 32, me whakaranu e koe ngā paipa matotoru me ngā paipa angiangi. E taunakihia ana kia whakamahia te 6 mō te paipa matua, me te 4 mō te paipa peka kia kore ai e ranea te pēhanga wai i te kāinga.
