Ka kite koe i te PE80 me te PE100 i ngā whakatakotoranga hangarau. He rerekē ngā tau, engari kāore i te mārama he aha te tikanga o tēnei mō tō kaupapa. Tērā pea ka arahi tēnei pōhēhētanga ki te whiriwhiri i tētahi kōwhiringa ngoikore ake, utu nui ake rānei.
Ko te rerekētanga matua ko te kaha. He 25% teitei ake te Kaha Hiranga e Hiahiatia ana (MRS) o te PE100 i te PE80. Mā tēnei ka angiangi ake ngā pakitara o ngā paipa PE100 mō te pēhanga ōrite, ka māmā ake, ka iti ake te utu, ā, ka pai ake te rere o te wai.
Ehara tēnei i te kōrero hangarau iti noa iho; he whakapainga taketake tēnei i roto i te pūtaiao rauemi, he nui ngā painga mahi. Hei kaihanga, ka taea e au te kī atu ki a koe ko teneke mai i te PE80 ki te PE100he taahiraa nui whakamua te paerewa ahumahi. Ka mārama tonu te kaiwhakahaere hokohoko mohio pērā i a Arief i Indonesia ki tēnei. Ka kite ia ka taea e PE100 te tuku i te mahi ōrite me te hua whai hua ake, māmā ake, me te ngāwari ake ki te tāuta. Ko te rerekētanga i waenga i ēnei tohu e rua ka pā ki ngā mea katoa mai i te tahua kaupapa ki te pono mō te wā roa o te pūnaha katoa.
He aha te rahi o te paipa PE100?
E hiahia ana koe ki ngā paipa mō tō kaupapa, engari kei te whakaaro koe mēnā kei te rite te rahi o te PE100 ki tāu e hiahia ana. Mā tēnei āwangawanga ka uaua ki te tohu i ngā rauemi me te whakamahere tika i te paipa o tō kaupapa.
He whānuitanga o ngā rahi paerewa kei te wātea mai ngā paipa PE100, mai i ngā diameter iti 20mm ki ngā diameter tino nui 2500mm. Ko te PE100 te momo rauemi, ehara i te rahi, nō reira ka taea te hanga ki te tata ki tetahi rahi e hiahiatia ana mō tetahi tono.
Ko tētahi o ngā āhuatanga e pōhēhētia ana ko te whakaaro ko te "PE100" e pā ana ki tētahi rahi. He mea nui kia mahara ko te PE100 te taumata rauemi. I taku wheketere, ka whakamahia e mātou tēnei taumata mahi-teitei kotahi hei whakaputa i ngā momo rahi paipa. Ka whakarerekē noa mātou i ngā mate whakaputa hei hanga paipa mai i te 20mm ki te 800mm, neke atu rānei. Ka taea te tuku i ngā diameter iti ake, tae atu ki te 110mm te nuinga, i roto i te...ngā koiri roa, e whakaiti nui ana i te maha o ngā hononga e hiahiatia ana mō te tāutanga. Ka hangaia ngā diameter nui ake i roto i ngā roa tika, ko te nuinga he 6, he 12 mita rānei te roa. Kei te wātea te rahi e hiahiatia ana e koe, nā te mea he maha ngā whakamahinga o te rauemi tonu. Ka taea te whakarerekē mō ngā mea katoa mai i te paipa wai iti o te kāinga ki te paipa wai nui o te tāone.
Ngā Rahi me ngā Whakamahinga o ngā Paipa PE100 Noa
| Awhe Diameter | Puka Noa | Ngā Taupānga Noa |
|---|---|---|
| 20mm – 110mm | Ngā koiri, ngā roa tika rānei | Ngā hononga whare noho, te whakamakuku wai, ngā paipa waea |
| 125mm – 630mm | Ngā roa tika (6m, 12m rānei) | Te tohatoha wai ā-tāone, ngā raina tukanga ahumahi |
| 710mm – 2500mm | Ngā roa tika | Te tuku wai nui, ngā putanga waipara, te keri maina |
Ko tēhea te mea kaha ake, PE, PVC rānei?
Me whiriwhiri koe i waenga i te PE me te PVC, ā, e kiia ana ēnei mea e rua he "kaha". He uaua ki te mōhio ko tēhea rauemi te mea tino pakari, ā, he pai ake mō ngā hiahia o tō tāutanga.
Kei te āhua o tō tautuhi i te kaha. He pakari ake te PVC, ā, he nui ake te kaha kume. Heoi, he ngāwari ake te HDPE (PE) ā, he nui ake te kaha pānga, inā koa i te rangi makariri. Ka taea e te HDPE te piko me te tu atu i ngā pānga ka pakaru te PVC.
Ina kōrero ngā miihini mō te "kaha," he maha ngā āhuatanga rerekē e pā ana ki a rātou. He tino pakari te PVC. Ko te tikanga he ātete ki te piko, he mea whai hua pea i roto i ētahi mahi i runga ake i te whenua, ina kore koe e hiahia kia totohu te paipa. Heoi, ko taua pakari anō ka pakarukaru te PVC. Ko te pānga koi mai i te toka i te wā e whakakī ana, i te taka rānei i te wā e tāuta ana i te rangi makariri, ka pakaru, ka pakaru rānei. Ko te HDPE te ritenga kē. He ngāwari, ā, he tino mīharo tōnaātete pāngaKa taea e koe te patu ki te hama, ā, tera pea ka pakaru noa iho. Nā te pakari o tēnei mea ka ngāwari ake te whakamahi i te wā tāutanga, ā, he pai ake hoki mō ngā paipa tanumia. Ka taea e ia te piko me ngā nekehanga whenua, te taunga oneone rānei, me te kore e whati, he painga nui tēnei mō te pono mō te wā roa.
Ngā Āhuatanga Kaha: HDPE vs. PVC
| Taonga | HDPE (PE100) | PVC |
|---|---|---|
| Pūmau (Pakeke) | I raro | Teitei ake |
| Te Kaha o te Pānga | Tino pai, ahakoa i ngā pāmahana iti | He pai, engari ka pakarukaru i te makariri |
| Ngāwari | Teitei (ka taea te piko me te takai) | Iti (he mārō) |
| Ātete ki te ngenge | Tino pai | Waenga |
He aha i whakamahia ai te HDPE i runga ake i te PVC?
Ka kite koe he iti ake te utu o te PVC, ā, he ngāwari hoki te tiki. Ka whakaaro koe he aha te take e whiriwhiri ai te tangata i te HDPE. Ki te kore e kite i ngā painga, ka rite te whakamahi i te HDPE ki te utu tāpiri koretake.
Whakamahia te HDPE ki runga ake i te PVC mō ōna hononga honohono ātete-tauraki, tōna ngāwari pai, me tōna pakari nui. Nā ēnei āhuatanga he pai mō te tāutanga kore-awaawa, he ātete ki te nekehanga whenua, ā, he otinga pono ake mō te wā roa e whakakore ana i te ngaronga wai mai i ngā hononga turuturu.
Ko te take nui rawa atu mō te whiriwhiri i te HDPE ko te tikanga honohono. Ko ngā paipa HDPEi honoa e te hanumitanga wera, e whakarewa ana i ngā pito o te paipa kia kotahi te wahi kirihou pumau, kotahi te āhua. He rite te kaha o te hononga ki te paipa tonu, ā, e kore e turuturu. Ka whakawhirinaki te PVC ki ngā gaskets, ki te sima whakarewa rānei, e hanga ana i ngā wāhi ngoikore o te raina ka pakaru i roto i te wā. Mō ngā ratonga wai, he tino pūtake nui o te ngaronga wai ēnei hononga turuturu. Tuarua ko te ngāwari. Mā te ngāwari o te HDPE ka taea te tāuta mehangarau kore-awaawa pērā i te keri anga whakapae (HDD)Ko te tikanga o tēnei, ka taea e koe te tāuta i tētahi paipa i raro i tētahi awa, i tētahi rori pukumahi rānei, me te kore e keri i tētahi awaawa nui. Ka penapenahia e tēnei he nui te wā me te moni i runga i te keri me te whakaora. Ka whakaratohia e ēnei painga he uara mō te wā roa e nui ake ana i te rerekētanga iti o te utu rauemi i te tīmatanga.
Ngā Painga Matua o te HDPE me te PVC
| Āhuatanga | HDPE | PVC |
|---|---|---|
| Ngākau Pono Tahi | Te Whakakotahitanga Wera (100% ātete turuturu) | Ngā takai, te piripiri rānei (ngā wāhi turuturu pea) |
| Tāutanga | Ngāwari, tino pai mō ngā tikanga kore-aukati | Pakari, me keri te awaawa tuwhera |
| Te pakari | Ka mimiti i te pānga me te nekehanga o te whenua | Pakaru, ka pakaru i raro i te taumahatanga |
| Utu mō te Wā Roa | He iti ake nā te kore turuturu me te iti ake o te tiaki | Teitei ake nā te ngaronga o te wai me te whakatikatika hononga |
Ka taea te whakapiri i te HDPE ki te PVC?
Me hono e koe tētahi paipa HDPE hou ki tētahi raina PVC o nāianei. Kei a koe te kāpia PVC, engari kāore koe i te tino mōhio mēnā ka mahi. Mā te whakamahi i te tikanga hono hē ka arahi pea ki tētahi turuturu nui.
Kāo, kāore rawa e taea te whakapiri i te HDPE ki te PVC. Nā ngā āhuatanga matū o te HDPE ka ārai i te piri o te sima whakarewa (piri) ki tōna mata. Hei hono i ngā rauemi e rua, me whakamahi koe i tētahi hononga ā-ringa pērā i te huihuinga flange, i tētahi hononga whakawhiti motuhake rānei.
Ko te take kāore e taea te whakapiri i te HDPE ko te take anō hoki he ātete ki ngā matū. He tino pumau tōna hanganga ngota, ā, he kore-pororaru, ko te tikanga ka paheke noa ngā whakarewa i te mata, kāore e pā ki a ia. Ka mahi te whakapiri PVC mā te whakarewa matū i te mata o te PVC kia honoa ngātahi. Kāore tēnei tukanga e mahi ki te HDPE. Ko te huarahi tika me te pono anake hei hono i ēnei rauemi e rua ko te whakamahi i te hononga miihini. Ko te tikanga tino noa ko te whakamahi i ngā flanges. Ka honoa e mātou hePūreretā HDPE flange (e kiia ana hoki he pito porotaka)ki te paipa HDPE. Kātahi ka whakapirihia he flange PVC ki te paipa PVC. Hei whakamutunga, ka whakapirihia ngā flange e rua me te whakamahi i te gasket rapa hei hanga i te hiri ā-wai. He tikanga māmā, kaha, me te haumaru e tukuna tonutia ana e mātou ngā hononga.
Ngā Wāhanga mō te Hononga Flange HDPE-ki-PVC
| Wāhanga | Mahi | Rauemi |
|---|---|---|
| Pito o te Puku HDPE | Ngā hononga ki te paipa HDPE hei hanga i tētahi mata whakarara | HDPE |
| Mowhiti Tautoko Rino | Ka paheke ki runga i te pito o te pou hei whakarato i te kaha o te whakapiri | Pirau, Rino Kowiri tira rānei |
| Pēneti PVC | I whakapirihia ki te paipa PVC | PVC |
| Pakitara | Ka waihanga i tētahi hiri i waenganui i ngā mata o ngā flange e rua | Rapa (hei tauira, EPDM) |
Whakamutunga
Ko te rerekētanga i waenga i te PE80 me te PE100 ko te kaha, ko te PE100 te mea pai ake. He pakari ake te HDPE, he ngāwari ake hoki i te PVC, ka honoa mā te hanumi ātete-tauraki, ā, me hono ā-ringa.
