Mā te whiriwhiri i waenga i te CPVC me te PVC ka raru, ka pakaru rānei tō pūnaha paipa. Mā te whakamahi i te rauemi hē ka raru pea, ka turuturu, ka pakaru rānei i raro i te pēhanga.

Ko te rerekētanga matua ko te ātete ki te pāmahana – ka taea e te CPVC te whakahaere i te wai wera tae atu ki te 93°C (200°F) i te mea ka herea te PVC ki te 60°C (140°F).Ngā takirere CPVChe paku nui ake te utu, ā, he pai ake te ātete ki ngā matū nā te hanganga he chlorine tō rātou.

I te tirohanga tuatahi, he tata rite tonu te āhua o ēnei takirere kirihou. Engari ko ō rātou rerekētanga ngota ka waihanga i ngā āputa mahi nui e tika ana kia māramahia e ngā kaihoahoa me ngā kaiwhakauru katoa. I roto i taku mahi me te tini o ngā kiritaki pērā i a Jacky, ka puta pinepine tēnei rerekētanga ina mahi ana ki ngā tono wai wera kei reira ngā paerewaPVCkāore e rahua. Ko te haukini tāpiri i roto iCPVCka hoatu he āhuatanga whakarei ake e tika ai te utu nui ake i ētahi āhuatanga, ko te PVC noa ia te whiringa ohanga mō ngā pūnaha wai paerewa.

Ka aha mēnā ka whakamahia e koe te PVC hei utu mō te CPVC?

Mā te wā poto o te penapena utu ka raru pea. Mēnā ka whiriwhiria he PVC e hiahiatia ana he CPVC, ka tūpono te piko, te ngatata, me te ngaronga pehanga kino i roto i ngā pūnaha wera.

Mā te whakamahi i te PVC i roto i ngā tono wai wera (neke atu i te 60°C/140°F) ka ngohengohe, ka piro te kirihou, ka turuturu, ka pakaru rānei. I ngā wā tino kino, ka pakaru te takirere i te pēhanga ina ngoikore i te wera, ka pā kino pea ki te wai me ngā tūponotanga haumaru.

E maumahara ana ahau ki tētahi take i tāuta ai te kiritaki a Jacky i ngā takirere PVC ki roto i tētahi pūnaha horoi rihi arumoni hei penapena moni. I roto i ngā wiki, ka tīmata te piko me te turuturu o ngā takirere. Nui atu te utu whakatikatika i ngā penapena tuatahi. Kāore e taea e te hanganga ngota o te PVC te tu atu i ngā pāmahana teitei tonu – ka tīmata te pakaru o ngā mekameka kirihou. Kāore i rite ki ngā paipa whakarewa, kāore e kitea tēnei whakangawari kia pakaru rā anō. Koia te take e tino whakahaeretia ai e ngā ture hanga te wāhi e taea ai te whakamahi i ia rauemi.

He aha ngā painga o te takirere pōro PVC?

He pēhanga tahua kei roto i ia kaupapa, engari kāore e taea te whakaiti i te pono.Ngā takirere PVCte taurite tino pai ina taea e ngā āhuatanga.

He tino whai hua te utu o ngā takirere PVC, he māmā ake te tāutanga, ā, he pai ake te ātete ki te waikura ki ērā atu mea whakarewa. He 50-70% te iti ake o te utu i te CPVC, ā, he tino pai te mahi i roto i ngā tono wai matao.

Mō ngā pūnaha wai matao, kāore he uara pai atu i te PVC. Mā ā rātou hononga whakarewa-whakarewa ka hangaia he hononga tere ake, he hononga pono ake i ngā hononga whakarewa miro, ka whakaiti i ngā utu mahi. Kāore i rite ki te whakarewa, kāore e waikura, e hanga putunga kohuke rānei. I Pntek, kua hangaia e mātou ā mātouNgā takirere PVCme ngā tinana kua whakapakaritia e mau tonu ana te pono ahakoa ngā tekau tau o te whakamahinga. Mō ngā kaupapa pēnei i a Jacky'sngā pūnaha whakamakuku ahuwhenuaMena kāore he āwangawanga mō te pāmahana, ko te PVC tonu te kōwhiringa mohio rawa atu.

He aha i kore ai e whakamahia te CPVC i ēnei rā?

Tērā pea ka rongo koe i ngā kereme kua tawhito haere te CPVC, engari he whānui ake te pono. Kāore i whakakorea e ngā whanaketanga rauemi ōna painga ahurei.

Kei te whakamahia whānuitia tonutia te CPVC engari kua whakakapia e te PEX me ētahi atu rauemi i roto i ētahi tono kāinga nā te utu. Heoi anō, he mea nui tonu mō ngā pūnaha wai wera arumoni ina pai ake te pāmahana teitei (93°C/200°F) i ngā momo kē atu.

Ahakoa kua piki haere te rongonui o PEX mō ngā mahi paipa whare, kei te mau tonu te tūranga kaha o CPVC i roto i ngā wāhanga matua e toru:

1. Ngā whare arumoni me ngā pūnaha wai wera pokapū
2. Ngā tono ahumahi e hiahia anaātete matū
3. Ngā kaupapa whakahou e rite ana ki ngā hanganga CPVC o nāianei

I ēnei āhuatanga, nā te kaha o te CPVC ki te whakahaere i te wera me te pēhanga me te kore e pāngia e te waikura o te konganuku, kāore e taea te whakakapi. Ko te whakaaro mō tōna ngaronga he mea nui ake mō ngā nekehanga o te mākete whare noho, kaua mō te tawhito o te hangarau.

He hototahi ngā hononga PVC me ngā hononga CPVC?

He ngāwari noa iho te whakaranu i ngā rauemi, engari ki te kore e tika te whakaranu, ka puta he ngoikore ka whakararu i te pūnaha katoa.

Kāo, kāore e hototahi tika ana. Ahakoa e whakamahia ana e ngā mea e rua te whakarewa whakarewa, he rerekē ngā sima e hiahiatia ana (kāore e taea e te sima PVC te hono tika i te CPVC, ā, kāore hoki). Heoi, kei te wātea ngā taputapu whakawhiti hei hono haumaru i ngā rauemi e rua.

Nā ngā rerekētanga o te hanganga matū, kāore e taea te whakawhiti i ngā sima whakarewa:

• Ka whakarewahia e te sima PVC te mata o te PVC hei hono
• He kaha ake te sima CPVC hei whakamārama i tōna hanganga pakari ake

Ko te ngana ki te akiaki i te hototahi ka arahi ki te ngoikore o ngā hononga ka puta pea i ngā whakamātautau pēhanga i te tīmatanga engari ka kore e angitu i te roanga o te wā. I Pntek, ka tūtohu tonu mātou:

1. Te whakamahi i te sima tika mō ia momo rauemi
2. Te tāuta i ngā hononga whakawhiti tika ina hiahiatia ngā hononga
3. Me tuhi mārama ngā tapanga ki ngā wāhanga katoa kia kore ai e ranea ngā raruraru

Whakamutunga

He rerekē ngā mahi a ngā takirere pōro PVC me te CPVC engari he rite tonu te hiranga—ko te PVC mō ngā pūnaha wai matao utu-pai, ko te CPVC mō ngā tono wai wera uaua. Mā te whiriwhiri tika ka noho haumaru, ka roa hoki te mahi. Me whakarite tonu te takirere ki ngā whakaritenga pāmahana me ngā matū motuhake o tō pūnaha mō ngā hua tino pai.
