1. Hua whakataki o Te Wera Atete Waikura Tauira Whakatauira Paipa Hiato {2492068} {2492068}
He mea nui te paipa hiato hei tauira mo te waikura me te wera-atete i roto i te punaha aroturuki taiao. Kei roto he huinga putorino kapia-atete me te mahi nui, te aroturuki i te pāmahana-whaiaro (te aroturuki hiko tonu) me nga taura utu, te paparanga whakamaarama o waho me te ringaringa whakamarumaru polyethylene (PE) mura. Ko te mahi whakawhāiti i te pāmahana aunoa o te whitiki whakamahana whakamahana whaiaro ka taea te whakarite kia mau tonu tetahi pāmahana i roto i te paipa tauira, kia rite ai nga tauira kua kohia ki nga uara tuatahi ka taea, ka mutu ka whakarite kia Ka taea e te punaha tirotiro taiao te kohi i nga tauira hau. E ai ki nga ahuatanga o te tauira hau, penei i te hanganga me te pāmahana, ka taea te whakamahi i nga rauemi rereke mo te pipeline tauira i roto i te paipa whakahiato anticorrosion me te wera-aukati tauira tauira, penei i te PFA (copolymer o tetrafluoroethylene me te perfluoroalkyl ether), FEP ( copolymer o tetrafluoroethylene me te hexafluoropropylene), PVDF (polyvinylidene fluoride), PE (te mura o te polyethylene), nylon 610, me etahi atu Ka taea te whiriwhiri i te whitiki whakamahana i runga i te reo, te iti me te teitei o te mahana, me te whakarite kia rite ki nga hiahia o nga kaiwhakamahi. I whakarārangihia tenei hua hei mahere whakatairanga hua hou matua i te tau 2002, ka tono mo te patent mo te motu i te tau 2001. I tenei wa, ko ta matou kamupene tetahi o nga kaihanga ngaio o tenei momo ngongo tauira.
He putorino hiato hiato-a-te waikura me te whakamaarama i te wera he uaua i titoa e te maha o nga taputapu, he maha nga punaha kua whakakotahi ki tetahi waahanga iti.
● Pūnaha tauira: ka taea te whakakotahi i nga ngongo tauira o nga momo momo me nga rawa: Teflon PFA, FEP, nylon 610, ngongo parahi, 316SS, 304SS, aha atu.
● Pūnaha wera: he pai te whakamarumaru waiariki, te aukati mura me te paparanga whakamaarama mama; Ko te pāmahana aunoa e whakawhāiti ana i te taura whakamaarama wera, te taura tirotiro wera hiko tonu ranei.
● Pūnaha hiko: te taura tohu taputapu, te taura utu me te taura whakahaere ka taea te whakauru ki te whakatutuki i nga hiahia o te whakaaturanga taputapu me te aroturuki.
● Pūnaha haumaru: E ai ki nga tikanga hangarau rereke, ka tiakina nga punaha katoa, ka wehea e te konumohe konumohe, he waea waea ranei hei whakatutuki i nga mahi aukati ahi, anti-static me te hiko hiko. Ko etahi o nga punaha kua rite ki nga kiriuhi parewai me nga putunga hei whakarei ake i te mura o te mura me te whakamarumaru ultraviolet. Ko te huinga o nga punaha maha ka whakauru i nga mahi maha me te ngawari ki nga kaupapa uaua. He pai tana mahi ki te whakarite i te mahi mamao me te tātaritanga mamao o te punaha. Ka taea e te punaha aroturuki whakamahana te aukati i te hau i roto i te pipeline mai i te whakamaarama me te uara ine kia nui ake i te haupapa, na reira ka whakarite i te tika o te ine me te hanga tikanga mo te whakarorohikotanga o te mana o te pokapū. Ko te whakakaha o waho ka taea te aukati i te whiti me te kino e pa ana ki etahi atu mea.
