I ngā rohe kua kapi i te hukapapa me te hukarere, ka pā te whiriwhiri i tētahi taura kotahi ki te haumaru me te pumau o te pūnaha hiko katoa. I ngā taiao hotoke tino kino, ka pakarukaru ngā taura PVC paerewa me te hipoki PVC, ka ngawari te pakarukaru, ka whakaiti i te mahi hiko, ka raru pea, ka tūpono rānei he tūponotanga haumaru. E ai ki te Paerewa Hoahoa Taura Hangarau Hiko, ko ngā rohe he iti rawa te pāmahana ā-tau i raro i te -15°C me whai taura pāmahana iti motuhake, ko ngā rohe i raro i te -25°C me whai taura hiko ātete makariri, taura ārai, taura ārai rīpene maitai rānei i hangaia mō rātou.
1. Te Pānga o te Makariri Nui ki ngā Taura
He maha ngā wero e pā ana ki ngā taura i ngā pāmahana iti. Ko te pakarukaru i te pāmahana iti te raruraru tino tika. Ka ngaro te ngāwari o ngā taura hiko kua hipokina ki te PVC, ka pakaru ina piko, ā, ka kore pea e tutuki i ngā hiahia o ngā taiao uaua. Ka pirau pea ngā rauemi whakamarumaru, inā koa ko te PVC, ka arahi ki ngā hapa tuku tohu, ki te turuturu hiko rānei. Ko ngā taura ārai, tae atu ki ngā taura ārai rīpene maitai, me ngā pāmahana tāutanga ki runga ake i te -10°C, engari he tino kaha ake ngā whakaritenga mō ngā taura hiko kāore i te ārai.XLPEMe whakamahana ngā taura kua whakamahanatia, ngā taura kua hipokina ki te PE, me ngā taura kua hipokina ki te LSZH i roto i te taiao wera mō te 24 hāora neke atu rānei i te ≥15°C i mua i te tāutanga kia mau tonu ai te mahi tino pai.
2. Te Mārama ki ngā Waehere Tauira Taura
Ko te whiriwhiri i te taura tika ka tīmata mā te mārama ki te waehere tauira, e whakaatu ana i te momo taura, te rauemi o te ara iahiko, te whakamarumaru, te uhi o roto, te hanganga, te uhi o waho, me ngā āhuatanga motuhake.
Ngā Rauemi Arataki: Ko ngā matua parahi ("T") he mea pai ake i ngā rohe makariri mō te arataki pāmahana iti pai ake. Ko ngā matua konumohe kua tohua ki te "L".
Ngā Rauemi Ārai: V (PVC), YJ (XLPE), X (Rapa). He pai ake te mahi pāmahana iti o ngā taura XLPE (YJ) me ngā taura rapa.
Ngā Rauemi o te Puranga: He iti te pāmahana o te PVC. He pai ake te ātete makariri o ngā taura hiko, ngā taura whakahaere, me ngā taura ngaohiko iti nā te PE, PUR (polyurethane), PTFE (Teflon), me ngā puranga LSZH.
Ngā Tohu Motuhake: TH (mākū pārūrū), TA (maroke pārūrū), ZR (ātete mura), NH (ātete ahi) tērā pea e tika ana. Tērā pea ka whakamahia hoki ētahi taura ārai, taura whakahaere rāneiRīpene Mylar or Rīpene Mylar Pepa Konumohehei wehenga, hei ārai, hei whakapakari rānei i te tiaki ā-ringa.
3. Kōwhiringa Taura mā te Mahana
Me ōrite ngā rauemi taura me te hanganga mō ngā taiao makariri rerekē hei ārai i ngā rahunga o te pūnaha:
> -15°C: Ka taea te whakamahi i ngā taura hiko kua hipokina ki te PVC paerewa, engari me >0°C te tāutanga. Ārai wera: PVC, PE, XLPE.
> -30°C: Me whakauru ngā rauemi o te hipoki ki te PE, ki te PVC ātete-makariri, ki ngā hipoki hiato nitrile rānei. Ārai: PE, XLPE. Te pāmahana tāutanga ≥ -10°C.
< -40°C: Me hanga ngā rauemi hipoki ki te PE, PUR, PTFE rānei. Ārai: PE, XLPE. Te pāmahana tāutanga ≥ -20°C. Ko ngā taura ārai, ngā taura ārai rīpene maitai, me ngā taura hipoki LSZH te mea pai mō te pono rawa atu.
4. Tāutanga me te Tiaki
Me whakarite marie te tāutanga taura ātete-makariri. He mea nui te whakamahana i ngā taura ina heke te pāmahana ki raro i ngā rohe kua tohua: 5–10°C (~3 rā), 25°C (~1 rā), 40°C (~18 hāora). Me whakaoti te tāutanga i roto i ngā hāora e 2 i muri i te wehenga atu i te wāhi rokiroki wera. Me ata pupuri ngā taura, kaua e taka, ā, me whakakaha ake ngā piko, ngā pari, ngā pūwāhi taumahatanga rānei. Tirohia ngā taura katoa i muri i te tāutanga, tae atu ki ngā taura ārai, mō ngā kino o te takotoranga, ngā kapiti, ngā take whakamahana rānei. Whakamahia te Rīpene Mylar, te Rīpene Mylar Pepa Konumohe rānei e hiahiatia ana hei ārai, hei wehe rānei i ngā taura tohu me te hiko.
5. Ngā Whakaaro Whānui
Haunga te pāmahana, whakaarohia ēnei āhuatanga ina whiriwhiri ana i ngā taura ātete-makariri:
Taiao Tāutanga: Ka pā te tanu tika, te rua taura, te paepae rānei ki te whakamararatanga wera me te tiaki ā-ringa. Me taurite ngā hipoki PE, PUR, PTFE, me LSZH kia rite.
Ngā Whakaritenga Mana me te Tohu: Arotakehia te whakatauranga ngaohiko, te kaha kawe iahiko, te pono o te tohu, me te ātete pokanoa. Tērā pea ka hiahiatia he Rīpene Mylar Pepa Konumohe hei tiaki i ngā taura ngaohiko iti, whakahaere, taputapu rānei.
Ngā Whakaritenga Ārai Mura me te Ātete Ahi: Tērā pea ka hiahiatia he ZR, NH, me te WDZ (kore-paowa iti) mō ngā wāhi o roto, o roto o te ana, o ngā wāhi kua kati rānei.
Ōhanga me te Oranga: He nui ake ngā utu tīmatanga mō ngā taura XLPE, PE, PUR, PTFE, taura ārai, taura rino rānei ātete-makariri, engari ka whakaitihia te wā whakakapinga me te wā kore mahi nā te kino o te pāmahana iti.
Mā te whiriwhiri i ngā rauemi taura ātete makariri tika, tae atu ki ngā taura PVC, XLPE, PE, PUR, PTFE, LSZH, ngā taura ārai, me ngā taura rino, ka whakarite i te pono o te pūnaha hiko, te mahi haumaru, me te mahi roa i ngā āhuatanga hotoke kino. He mea nui te whiriwhiri tika i ngā taura, ehara i te mea mō te pumau o te hiko anake, engari mō te haumaru hiko whānui hoki.
