Kei te ngana koe ki te whiriwhiri i te rauemi paipa tika. He pōhēhē ngā waehere pēnei i te PE 80 me te PE 100, ā, mā te whiriwhiri hē ka raru pea te pūnaha me te utu nui o ngā whakatikatika.

Ko te PE 100 te whakatupuranga hou o te Polyethylene Matotoru-Teitei (HDPE). Ko te tikanga o te "100" he 10.0 MPa te Kaha Hiranga e Hiahiatia ana (MRS), ā, he kaha ake i ngā rauemi tawhito. Mā tēnei ka taea ngā paipa he angiangi ake ō rātou pakitara, ā, ka taea tonu te tu atu ki te pēhanga teitei.

Ina kōrero ahau ki ngā kaiwhakahaere hoko pēnei i a Budi, ko te pātai mō "PE 80 vs. PE 100"ka puta tonu mai. He iti noa te rerekētanga, engari ko taua tau te mea nui ki te mahi a te rauemi. E tohu ana i ngā tekau tau o te hangarau matū me te auahatanga. Ko te mārama ki tēnei whakarōpūtanga ngāwari te taahiraa tuatahi ki te whiriwhiri i te paipa tino pono me te utu-whai hua mō tētahi kaupapa. Me wehewehe tātou he aha te tikanga o aua tau mō tō pakihi.

He aha te rerekētanga i waenganui i te PE 80 me te PE 100?

Kei te whakataurite koe i ngā utu, ā, ka kite koe i ngā paipa PE 80 me PE 100. He iti ake te utu mō te PE 80, engari he kaha rawa? He mōrearea nui te whiriwhiri i runga i te utu anake.

Ko te Kaha Whakahirahira e Hiahiatia ana (MRS) o te PE 100 he 10.0 MPa, ko te PE 80 he 8.0 MPa. Mā tēnei ka kaha ake te PE 100, ka taea ai e ia te tu atu ki te pēhanga teitei ake. Mō te whakatauranga pēhanga ōrite, ka taea e te paipa PE 100 te whai pakitara angiangi ake, ka penapena rauemi me te taumaha.

Ko te tau i roto i te ingoa te mea nui rawa atu kia mārama. Ehara i te mea he kupu hokohoko noa iho; he whakarōpūtanga pūtaiao i runga i te kaha mō te wā roa. Ko teTe Kaha iti rawa e hiahiatia ana (MRS)ka whakatauhia mā te whakamātautau i te rauemi i raro i te pehanga mō te wā roa hei matapae i tōna mahi mō ngā tau 50.

• PE 80:Ko tōna MRS he 8.0 MPa. Koinei te paerewa mō ngā tau maha, ā, he rauemi pai tonu.
• PE 100:Ko tōna MRS he 10.0 MPa. He pikinga 25% tēnei o te kaha iti rawa atu i te PE 80.

Mā tēnei kaha tāpiri ka hoatu ki a koe ētahi painga nui e rua. Tuatahi, ka taea e koe te whakamahi i tētahi paipa PE 100 hei whakahaere i ngā pēhanga teitei ake i tētahi paipa PE 80 he rite te matotoru o te pakitara. Tuarua, ā, he mea noa ake, ka taea e koe te whakamahi i tētahi paipa PE 100 he angiangi ake te pakitara hei whakatutuki i te whakatauranga pēhanga ōrite. Ko te tikanga o te pakitara angiangi he iti ake ngā rauemi mata, ka māmā ake te paipa, ā, he maha ngā wā ka iti ake te utu. Ka hoatu hoki ki te paipa he diameter ā-roto nui ake, ka whakapai ake i ngā āhuatanga rere.

He aha te tikanga o te paipa HDPE kounga PE 100?

Ka kite koe i te "PE 100 Grade" i runga i te pepa whakatakotoranga. He ngāwari noa te wareware he kupu hangarau noa iho tēnei, engari he pānga tika tēnei tohu ki te mahi a te paipa me te pono mō te wā roa.

Kua whakamanahia te paipa HDPE "paerewa PE 100" he mea hanga mai i te kapia PE 100 tino pai. Mā tēnei ka whakamanahia tōna kaha teitei (10.0 MPa MRS), tōna whakatauranga pēhanga pai rawa atu, me tōna ātete pai ki te puhoi o te tipu o ngā kapiti, kia roa ai te ora o te mahi.

Ina kite koe i "Tau PE 100"," he taurangi mō te kounga me te mahi. Ko te tikanga ehara i te mea he kirihou noa iho te paipa; he kapia kua hangaia, kua whakamatautauria kia tutuki ai te paerewa teitei. Haunga te kaha teitei ake, he painga nui anō hoki kei tēnei taumata. Ko tētahi o ngā mea nui ko tōna ātete pai kiTe Tipu Puhoi o te Kapiti (SCG)I te wā tāutanga, ka taea e ngā paipa te whiwhi rakuraku iti, ngā kohao rānei. Mō ngā rauemi kounga iti, ka taea e ēnei hapa iti te tipu haere hei kapiti nui i roto i ngā tau maha o te huringa pēhanga, ā, ka mutu ka pakaru te paipa. Kua hangaia te PE 100 kia ātete ki tēnei, kia roa ake ai, kia ngāwari ake ai hoki ki ngā āhuatanga tāutanga o te ao tūturu. Koinei te kōwhiringa pai mō ngā paipa ka tanumia, ā, me roa mō ngā tekau tau, me te kore he raruraru.

He aha te hiranga o te modulus of elasticity o te PE 100?

Ka pānui koe i te kupu "modulus of elasticity" i runga i tētahi pepa raraunga, ā, ka pōuriuri ō kanohi. Te āhua nei kāore he pānga o tēnei kupu hangarau, engari e whakaahua ana i tētahi o ngā painga mahi nui rawa atu o te rauemi.

Ko te modulus o te ngāwari e ine ana i te pakari. He iti te modulus o te PE 100, ā, he tino ngāwari. Mā tēnei ka taea e te paipa te piko i ngā arai, ka tukuna i roto i ngā koiri roa, ā, ka whakamahia i roto i ngā tikanga tāutanga kore-awa, ka tino whakaiti i ngā utu tāutanga.

He mea nui kia kaua e whakapoauautia te kaha me te pakari. He tino pakari te rauemi pēnei i te karāhe, engari kāore e kaha ki te pā mai nā te mea he pakarukaru. He tino kaha, he tino ngāwari hoki te PE 100. He painga nui tēnei ngāwari i te wā tāutanga. Mō ngā diameter iti ake, ka taea e mātou te tuku i te paipa i roto i ngā koiri roa o te 100 mita, neke atu rānei. Ko te tikanga he iti ake ngā hononga e hiahiatia ana, ka penapena i te nui o te wā, ā, ka whakakorea ngā ngoikoretanga pea. Mō ngā diameter nui ake, mā tēnei ngāwari ka taea te whakamahi i te paipa i roto i ngā tikanga tāutanga hou pēnei i teTe Keri Aronga Whakapae (HDD)Mā tēnei ka taea e ngā kaiwhakauru te tō i te paipa ki raro i te whenua, me te kore e keri i tētahi awaawa roa, whakararuraru. He tino pai tēnei mō te whiti i ngā awa, i ngā rori, i ngā wāhi tairongo taiao rānei. I roto i tētahi whenua pēnei i a Indonesia me ngā whenua rerekē, ka taea e tēnei ngāwari te penapena moni nui i runga i ngā utu tāutanga ki te whakaritea ki ngā paipa pakari.

He pai ake te PE 100 i te PVC?

He rauemi paipa tino noa te PVC, ā, kua mōhio pea koe ki tēnei mea. He iti ake te utu tīmatanga, nō reira he aha koe me huri ai ki te PE 100?

Ko te PE 100 te mea pai ake mō ngā pūtake huna. Ko ōna painga matua i te PVC ko tōna ngāwari, te ātete pānga teitei ake, me ngā hononga honohono ātete turuturu. Ko ngā hononga whakarewa-whakarewa, ngā hononga rānei kua whakakikoruatia ki te haukoti o te PVC te nuinga o te wā te ngoikore rawa o te pūnaha, he raruraru ka whakakorea rawatia e te whakarewa honohono.

Ahakoa he pai ngā rauemi e rua, he rerekē ngā kaha i hangaia mō ēnei. Ko te painga nui o te PE 100 ko te tikanga honohono.

Ko ngā hononga te mea nui. Ina whakamahanahia he paipa PE 100 ki te whakakā, ka noho te hononga hei wahi kirihou kotahi, pumau. Kāore e turuturu. Ki te PVC, kei te whakamahi koe i te whakarewa matū, i te gasket rapa rānei. Ko ēnei hononga te wāhi tuatahi ka turuturu i roto i te wā roa. Mō ngā paipa tanumia katoa e nui ana te utu me te uaua ki te whakatika, ko te hononga ārai turuturu o te PE 100 te mea pai rawa atu hei haumitanga mō te wā roa.

Whakamutunga

Ehara i te mea he tau noa iho te PE 100. Nā tōna kaha, tōna ngāwari, me ōna hononga honohono ātete-tauraki, he mea hou, he mea pono hoki mō ngā kaupapa paipa roa.
