Me whai takirere koe mō tētahi raina ahumahi, matū rānei, engari kāore koe i te tino mōhio mēnā ka taea e te kirihou te tu atu ki te pēhanga. Mēnā ka hē te whiriwhiri i te takirere, ka puta pea he turuturu morearea, he utu nui mō te wā whakamutu, me te aituā nui mō te haumaru.

He takirere pōro PP kounga teitei, pērā i ā mātou tauira Pntek, he whakatauranga pēhanga PN16 tōna. Ko te tikanga ka taea e ia te whakahaere haumaru i te 16 pae (tata ki te 235 PSI) i te pāmahana rūma. He mea nui, ka heke tēnei kaha i te pikinga o te pāmahana wai.

Ina kōrero ahau ki ngā hoa mahi pērā i a Eric Lim i Mareia, ehara te whakatauranga pēhanga i te tau noa iho; engari mō te haumaru me te whakawhirinaki. Ko tāna kamupene e tuku ana i ngā kaupapa puta noa i te Tonga-mā-rāwhiti o Āhia, ā, me mōhio rātou kāore e rahua ngā hua e hokona ana e rātou. Ko te whakatauranga pēhanga kua whakahuatia mō te takirere te tīmatanga, engari ko te tohungatanga tūturu kei roto i te mārama ki tana whanonga i raro i ngā āhuatanga o te ao tūturu. Ko tēnei mōhiotanga te mea e wehewehe ana i tētahi tauwhitinga ngāwari mai i tētahi hononga tūturu, ā, koinei tā mātou e arotahi ana ki Pntek.

He aha te whakatauranga pēhanga o te takirere pōro?

Ka kite koe i ngā kupu pēnei i te CLASS 150, PN16, me te CWP i runga i ngā pepa raraunga, ā, ka pōhēhē koe. Ka taea e tēnei pōhēhē te arahi ki te tono hē i te takirere, ka hanga he pūnaha morearea mō tō kiritaki.

Mā te whakatauranga pēhanga ka mōhio koe ki te pēhanga mōrahi ka taea e te takirere te whakahaere haumaru i tētahi pāmahana motuhake. He rerekē ngā paerewa e whakamahia ana pērā i te PN (Pākehā), te Akomanga (Amerika), me te CWP (Whānui), nō reira me mōhio koe ki te pūnaha e titiro ana koe.

Me whakamārama tātou i ēnei kupu nā te mea he māmā ake i tōna āhua. Ko te whakatauranga pēhanga te whakatakotoranga haumaru tino nui mō tētahi takirere. Heoi, he rerekē ngā pūnaha e whakamahia ana e ngā wāhanga rerekē o te ao me ngā ahumahi rerekē, ā, ka pōhēhē pea. Mō ngā pūnaha paipa kirihou, ka kitea pinepinetia e koe tePNwhakatauranga. Ko te tikanga o "PN" heIngoa Whakahē, arā, ko te reo Wīwī mō te Pēhanga Ingoa. E tohu ana i te pēhanga mōrahi i roto ipaeka taea e te wāhanga te tu atu i te pāmahana rūma (20°C). Ko tētahi atu whakatauranga noa koCWP, te Pēhanga Mahi Matao rānei. He rite tēnei ki te PN, e whakaatu ana i te pēhanga mōrahi mō ngā pāmahana taiao. Mō ngā takirere ahumahi, whakarewa rānei, tera pea ka kite koe i tētahiAkomangawhakatauranga (hei tauira, Akomanga 150, Akomanga 300), he paerewa Amerikana (ANSI) e tautuhi ana i ngā rohe pēhanga puta noa i te whānuitanga o ngā pāmahana. Mō tā mātou mahi, ko te arotahi ki te PN te mea nui.

He aha te whakatauranga pēhanga mō ngā hononga polypropylene?

Kua whakaūtia e koe kei te tika tō takirere, engari me pēhea ngā hononga e hono ana? Ko te kaha o te pūnaha ko tōna wāhanga ngoikore rawa, ā, ki te kore e ōrite te hononga, ka raru pea.

Ka whakatauria hoki ngā hononga polypropylene mā te whakamahi i te pūnaha PN, ko te tikanga he PN10, he PN16 rānei. Mō tētahi pūnaha pono, me rite, me nui ake rānei te whakatauranga pēhanga o ō hononga me ō paipa i te whakatauranga o ō takirere.

Ka whakamahara tonu ahau ki a Eric Lim kāore te takirere e mahi takitahi. Kei te hanga koe i tētahipūnaha. Ki te tāuta koe i tētahi takirere pōro PN16 kaha engari honoa kiNgā hononga PN10, ko te pēhanga whakahaere mōrahi o tō pūnaha katoa ko PN10 anake (10 pae). Ko te wāhanga ngoikore rawa te mea e whakatau ana i te kaha o te mekameka katoa. Koia mātou i whakarite ai i tā mātou PntekNgā takirere pōro PPhe PN16 pakari. Mā tēnei ka puta he turanga pakari, engari he mea nui kia honoa ki ngā paipa me ngā taputapu PN16 kia mau tonu ai te kaha pēhanga teitei puta noa i te raina katoa. Ko te mea tino nui, inā koa kingā kirihou werapērā i te polypropylene, ko te pāmahana. I te wera haere o te wai, ka ngawari haere te rauemi, ā, ka tino heke tōna kaha ki te pupuri i te pēhanga. Ka kiia tēnei ko te 'derating', ā, me whai tonu koe i ngā tohutohu a te kaihanga.tūtohi pēhanga-pāmahanakia mahi haumaru ai.

E hia te psi ka taea e te takirere pōro te pupuri?

Ko tāu e hiahia ana he whakautu māmā noa iho i roto i te PSI, engari he maha ngā wā kei roto i te "pae" me te "PN" ngā whakatakotoranga. He mōrearea te huri tere i roto i tō hinengaro ina kei te tūpono te haumaru me te pono o ngā taputapu.

He rerekē rawa tēnei, mai i te 150 PSI mō ētahi takirere kirihou ki te neke atu i te 10,000 PSI mō ngā takirere whakarewa pēhanga teitei motuhake. Hei kimi i te PSI, tahurihia mai i te whakatauranga PN: ko te 1 pae he tata ki te 14.5 PSI.

Kāore he whakautu kotahi mō tēnei pātai, koia te mea nui kia tirohia te takirere motuhake e whakamahia ana e koe. Ko te rauemi (PP, PVC, Parahi, Kowiri tira), te rahi, me te hoahoa katoa e whakarerekē ana i te whakautu. Heoi, ka taea e mātou te whakangawari i tēnei mō ā mātou hua. Ā mātou PntekNgā takirere pōro PPhe PN16 te whakatauranga. He māmā noa te tahuritanga, ā, me mōhio te katoa o tō rōpū ki tēnei: ​​whakareatia te uara o te pae ki te 14.5. Nō reira, ko te whakatauranga PN16 te tikanga ka taea e te takirere te pupuri i te 16 pae pēhanga. Hei kimi i te PSI, tatauhia: 16 pae x 14.5 PSI/pae = 232 PSI. He maha ā mātou whakaawhiwhi i tēnei ki235 PSImō tētahi tau mārama, haumaru hoki. Koinei te whakatauranga i te pāmahana taiao. Mena kei te rere te wai o tō kaihoko i Kuala Lumpur i te 60°C (140°F) mā te raina, kāore e whai mana taua whakatauranga 235 PSI. Ka iti iho te pēhanga haumaru, e whakaaturia ana i runga i tete piko whakaheke.

Whakatauranga PN	Pēhanga i te Pae	Pēhanga i roto i te PSI (tata)
PN10	10 pae	145 PSI
PN16	16 pae	235 PSI

PN25	25 pae	362 PSI

He aha te takirere pōro PP?

Ka kitea e koe ngā takirere PVC me te CPVC i ngā wāhi katoa, nō reira ka whakaaro koe he aha me whakaaro koe ki te PP. Mēnā kāore koe i te mōhio ki ngā painga ahurei o te polypropylene, tera pea ka ngaro i a koe te otinga tino pai mō tō kiritaki.

He takirere porowhita-hauwhā te takirere porowhita PP, he mea hanga mai i te polypropylene, he kirihou wera e arohaina ana mō tōna ātete matū whakamiharo. He whiringa pakari, māmā, ā, he pai te utu mō te whakahaere i ngā wai waikura ka whakangaro i ngā takirere whakarewa.

Ko te kaha o te polypropylene ko tōna ātete matū. He tino pai tōna tū atu ki te whānuitanga o ngā waikawa, ngā kawakore, ngā tote, me ngā matū ahumahi. Nā tēnei ka waiho hei rauemi matua mō ngā ahumahi pēnei i te tukatuka matū, te maimoatanga wai, me te ahuwhenua. I Pntek, i kite mātou i te pūmanawa, ā, i whakatau mātou ki te whakapai ake. I whakawhanakehia e mātou ā mātou akeTakirere Pōro Kōpeketanga PPi runga i tētahi hoahoa pokepoke motuhake, he mea patent. Mā tēnei ka taea e mātou te whakahaere katoa i te kounga me te mahi. Ko tētahi āhuatanga matua ko tā mātou whakapau kaha ki tētahiWhakatauranga PN16 mō ngā rahi katoa, mai i te mea iti ki te mea nui rawa. Kāore tēnei i te mea noa i te mākete, engari e whakapono ana mātou me rite tonu te haumaru me te kounga. Koinei tētahi o ngā take nui e tino hokona ana ā mātou takirere i ngā mākete tono nui puta noa i te Tonga-mā-rāwhiti o Āhia, te Waenganui-rāwhiti, me Amerika ki te Tonga. He otinga pono, he utu hoki tā rātou e tuku ana mō te whakahaere haumaru i ngā matū me te wai.

Whakamutunga

He mea nui te whakatauranga PN16 o te takirere pōro PP, engari me whai whakaaro tonu ki te pāmahana. He mea nui te mārama ki tēnei whanaungatanga hei hanga i tētahi pūnaha haumaru, pono, me te roa hoki mō ō kiritaki.
