Ka kite koe i te kupu "PE100" i roto i te pepa whakaritenga mō ngā paipa HDPE, ā, ka pōhēhē koe. Nā tēnei kupu hangarau, he uaua ki te tino mohio kei te whiwhi koe i te hua tika mō tō kaupapa.
Ehara te PE100 i te rauemi motuhake mai i te HDPE; koinei te whakarōpūtanga mahi teitei rawa atu, te taumata rānei o te kapia HDPE. Ko te "100" e tohu ana i te Kaha Rawa e Hiahiatia ana (MRS) teitei, e waiho ana hei paerewa hou mō ngā paipa pēhanga kaha, pono hoki.
I roto i aku mahi hanga pūnaha paipa kirihou e rua tekau tau te roa, he ariā taketake tēnei e whakarite ana i te haumaru me te roa o te mahi. Whakaarohia te HDPE hei ingoa whānau, ā, ko te PE100 te mema tino kaha o taua whānau. Mō tētahi kaiwhakahaere hoko pērā i a Arief i Indonesia, kāore e taea te whiriwhiri i te "PE100". Ka tangohia ngā āhuatanga pōhēhē katoa, ā, ka whakamanahia kei te paipa te kaha hangarau hei whakahaere i ngā pēhanga o ngā hanganga wai nui. Me wehewehe tātou i te tikanga o tēnei momo me tōna whakataurite ki ētahi atu.
Ko tēhea te mea pai ake, PE80, PE100 rānei?
Kei a koe ngā utu mō ngā paipa PE80 me PE100. Ki te kore he māramatanga mārama, he mea tika te whiriwhiri i te kōwhiringa iti ake te utu engari he hapa pea. He nui ake te uara o te PE100.
He pai ake te PE100 i te PE80 mō ngā mahi paipa pēhanga. He kaha ake tōna, ā, ka taea e ia te whakahaere i te pēhanga ōrite ahakoa he angiangi ake te pakitara. Mā tēnei ka māmā ake te paipa, ka iti ake te utu ki te hanga, ā, ka nui ake te diameter o roto mō te rere pai ake.
E pā tika ana ngā tau o ēnei tohu ki tō rātou kaha mō te wā roa. Kei a PE80 tētahiTe Kaha iti rawa e hiahiatia ana (MRS)o te 8.0 MPa, ko te MRS a PE100 he 10.0 MPa. He pikinga nui taua 25% o te kaha i roto i te pūtaiao rauemi. Mai i te tirohanga hangahanga, he mea nui tēnei. Ko te tikanga mō tētahi whakatauranga pēhanga, pērā i te PN16, ka taea e tātou te whakamahi i te iti iho o ngā rauemi hei hanga i te paipa PE100. Ka inehia tēnei e teŌwehenga Ahu Paerewa (SDR). Ko te SDR o te paipa PE100 PN16 he 11, ko te paipa PE80 PN16 ia me matotoru ake te pakitara, kia 9 te SDR. Ehara i te mea he kaha ake te paipa PE100 engari he pai ake hoki. Ka penapena i ngā utu rauemi, ka whakaiti i te taumaha o te kaipuke, ā, ka māmā ake te whakahaere i te wāhi mahi mā ngā kaimahi tāutanga.
PE100 me PE80: He Whakataurite Whaihua (mō ngā Paipa PN16)
| Āhuatanga | Paipa PE80 | Paipa PE100 | Te Painga PE100 |
|---|---|---|---|
| MRS | 8.0 MPa | 10.0 MPa | Rauemi kaha ake 25% |
| SDR | SDR 9 | SDR 11 | Pakitara angiangi mō te pēhanga ōrite |
| Taumaha | Taumaha ake | Māmā | He māmā ake te kawe me te tāuta |
| Rere | He iti ake te poka o roto | Poka ā-roto nui ake | Te kaha rere teitei ake |
He aha te rerekētanga i waenganui i te PE 40 me te PE100?
Tērā pea ka kite koe i te "PE 40" i runga i tētahi tuhi hangarau tawhito rawa, i tētahi whakatakotoranga rānei. He mea nui kia mōhio koe mēnā he rauemi rite tēnei. He momo tawhito tēnei mō ngā paipa pēhanga.
He tino nui te rerekētanga. He rauemi hou, he kaha te PE100, e 2.5 ngā wā he kaha ake i te PE 40 mō te wā roa. Ko te PE 40 he momo polyethylene tawhito, he reanga tuatahi, kāore e pai mō ngā mahi paipa pēhanga o ēnei rā.
E whakaatu ana tēnei pātai i te ahunga whakamua whakamiharo kua tutuki i a tātou i roto i te matū polymer. Ko te PE 40 tētahi o ngā rauemi polyethylene tino tuatahi i whakamahia mō ngā paipa i ngā tekau tau ki muri. HeTe Kaha iti rawa e hiahiatia anao te 4.0 MPa anake. Mēnā ka ngana koe ki te hanga i tētahi paipa pēhanga PN10 (10 pae) mai i te PE 40 i ēnei rā, me tino matotoru, me tino pakari te pakitara, ā, kāore e taea te whakamahi, ā, he tino utu nui hoki. Ko te whanaketanga mai i te PE 40, tae atu ki te PE 63 me te PE 80, ki te paerewa o nāianei o te PE100 he kōrero mō te hanga rauemi kaha ake, pono ake, me te whai hua ake. I tō mātou wheketere, kāore mātou e whakaaro ki te whakamahi i tētahi kapia e mahi ana pērā i te PE 40 mō ngā paipa pēhanga. Ko te kapia PE100 e whakamahia ana e mātou e whakarato ana i ngā āhuatanga mahi me te haumaru e hiahiatia ana e ngā kaupapa hanganga hou. Mēnā ka tūtaki koe ki te PE 40 i roto i tētahi whakatakotoranga, me whakahou tonu ki te PE100.
Te Peke Whakatipuranga i roto i te Kaha PE
| Tau | Te Kaha iti rawa e hiahiatia ana (MRS) | Te Wā o te Whakamahinga | Tūnga |
|---|---|---|---|
| PE 40 | 4.0 MPa | ngā tau 1950 | Kua tawhito mō ngā paipa pēhanga |
| PE 63 | 6.3 MPa | Ngā tau 1960-1980 | I whakakapia nuitia |
| PE 80 | 8.0 MPa | Ngā tau 1980-2000 | Kei te whakamahia tonu i roto i ētahi tono |
| PE100 | 10.0 MPa | Ngā tau 1990 ki nāianei | Paerewa ā-ao o nāianei |
He aha te PN16 HDPE PE100?
Ka kite koe i tēnei rārangi roa o ngā reta me ngā tau i runga i tētahi whakatakotoranga kaupapa. He āhua uaua, he whakamataku hoki. He whakaahuatanga tino tika, he āwhina hoki mō te paipa.
Koinei te whakatakotoranga hangarau katoa mō tētahi paipa. Ko te tikanga o te "PN16" he 16 pae te pēhanga o te paipa. Ko te "HDPE" te rauemi, ko te Polyethylene Matotoru-Teitei. Ko te "PE100" te taumata kaha-teitei motuhake o taua rauemi. E whakaahua ana i tētahi paipa tino kaha.
Koinei tonu te momo whakatakotoranga mārama e hiahiatia ana e ngā miihini me ngā kaiwhakahaere hokohoko. Kāore e waiho he wāhi mō ngā hapa, ngā whakamārama hē rānei. Me wehewehe katoa tātou.
- PN16:Ko te 'PN' he tikanga mō "Pression Nominale," arā, ko te tikanga o te reo Wīwī mō te Nominal Pressure. Ko tōna tikanga, kua hangaia te paipa kia mahi tonu me te pēhanga ā-roto o te 16 pae (tata ki te 232 PSI) i te 20°C.
- HDPE:E tohu ana tēnei ko te rauemi matua ko te Polyethylene Kiato-Teitei, e mōhiotia ana mō tōna pakari me te ātete ki ngā matū.
- PE100:E whakaatu ana tēnei he nui te Kaha Whakahirahira e Hiahiatia ana o te kapia HDPE e whakamahia ana, arā, ko te 10 MPa.
Hei kaihanga, mā te kitenga i tēnei whakatakotoranga katoa ka mōhio ahau ki te mea tika hei hanga. He hononga ēnei kupu katoa. Hei whakatutuki i te whakatauranga PN16 mā te whakamahi i te kapia PE100, me hanga te paipa me te matotoru pakitara motuhake, ka hua ake he SDR o te 11. Mā tēnei whakaahuatanga katoa ka whakarite kia kōrerohia te hua kotahi e te katoa—te kaihoahoa, te kaihanga, me te kaiwhakauru.
He aha te tikanga o te PE100?
E mōhio ana koe he pai te PE100, engari kāore koe i te mōhio ki te tikanga o te ingoa. Mā te mārama ki te ingoa ka maumahara koe he aha i tika ai te kōwhiringa. Ko tōna tikanga he kaha, he pono hoki.
Ko te "PE" he tohu mō te Polyethylene, te momo kirihou. Ko te "100" e pā ana ki tōna Kaha Rawa e Hiahiatia ana (MRS) i muri i te 50 tau o te mahi. E tohu ana i te ahotea porowhita roa o te 10.0 MPa, ka whakareatia ki te 10 kia whiwhi ai i te tohu "100".
Koinei te taipitopito hangarau tino nui o te rauemi. Kāore te whakatauranga kaha i ahu mai i tētahi whakamātautau pahū poto noa iho. He uara hangarau roa tēnei i ahu mai i ngā whakamātautau whānui. Ka matapaetia e ngā whakamātautau te kaha o te rauemi i muri i te pēhanga ā-roto tonu mō ngā tau 50. Ko te "aukati porowhita" ko te kaha i roto i te pakitara paipa e ātete ana ki te pēhanga o te wai, o te hau rānei e ngana ana ki te pahū. Ko te whakarōpūtanga PE100 he taurangi ka taea e te rauemi te tu atu i te ahotea tonu o te 10 Megapascals mō taua wā 50-tau i te pāmahana paerewa. Ko tēnei huarahi whakatauranga pumau, roa-wā te take e whakawhirinakihia ai ngā paipa PE100 mō ngā hanganga nui e tika ana kia roa mō ngā whakatipuranga. He kupu whakaari mō te pakari, ā, koinei te turanga e hanga ana mātou i te ingoa o tā mātou kamupene.
Whakamutunga
Ko te PE100 te momo e tautuhi ana i ngā paipa HDPE hou. Ka whakamanahia he kaha teitei, ka whakarite kia pono mō āu kaupapa tino nui mō te wā roa. Me tohu tonu te PE100.
Mena kei te hiahia koe i tētahi whakatau tika e pā ana ki tō rahinga, ngā tikanga tuku, me ngā whakaritenga, tēnā whakapā maiwhakapā maimō tētahi whakatau utu tere, ngaio hoki.
