Ko te takirere pōro polyethylene (PE) hau raro whenua he wāhanga whakahaere matua i hangaia mō ngā pūnaha paipa polyethylene (PE) raro whenua i roto i te tuku hau me te wai o ngā tāone. He hanganga kirihou (PE) katoa tēnei takirere, ko te polyethylene (PE100, PE80 rānei te rauemi matua), ā, he ōwehenga rahinga paerewa (SDR) o te 11. He tino pai te ātete ki te waikura, te ārai i te koroheketanga, me te mahi hiri. Ko te āhuatanga hoahoa matua ko te whakaurunga o te takirere matua me ngā takirere hau rua, e āhei ai te whakatuwheratanga me te kati haumaru me te watea o te pūnaha paipa, me ngā mahi whakaputa hau me te whakakapinga waenga. Kei raro whenua te takirere e tanumia tika ana, ā, ka taea te whakahaere mai i te mata me te ringaringa tiaki me te kī motuhake, e tino whakangawari ana i te tukanga tiaki. He kaiwhakaoho pai mō te whakarite i te whakahaere haumaru me te watea o ngā whatunga paipa PE raro whenua.
Ngā Āhuatanga Mahi
Hiritanga Pai Rawa: Ka whakamahia he hanganga hiri mānu e whakakī ana i a ia anō kia kore ai e turuturu i roto, i waho hoki o te takirere, e whakarato ana i te haumaru me te pono.
Pūmau: Kāore e hiahiatia he maimoatanga ārai-waikura, ārai-ā-wai, ārai-pakeke rānei mō te hanganga kirihou katoa, ā, he roa te ora tae atu ki te 50 tau i raro i ngā tikanga hoahoa.
Ngāwari te Whakahaere: He mama te rahi, he iti te taipana whakatuwhera me te kati, ā, he kī motuhake hei whakahaere i te whenua.
Te Tāutanga me te Tiaki Māmā: Ka taea te hono atu ki ngā paipa PE mā te whakamahi i ngā tikanga whakakotahi hiko paerewa, ngā tikanga whakakotahi pū rānei, me te tino whai huatanga o te hanga. Ko te tiaki auau me whakatuwhera me te kati i ia toru marama anake.
Mahi Whakapūngao Rua: Kua whakauruhia ki ngā putanga pūngao rua, hei whakahaere i te tukunga haumaru o te hau toenga i te wāhanga paipa o raro i muri i te katinga o te takirere matua, he āhuatanga haumaru nui mō te tiaki, te whakahoutanga, te whakahaere rānei i ngā āhuatanga ohorere.
Ngā Tikanga Whakahaere
Pāpāho e tika ana: Hau māori parakore, hau hinu wairewa, hau horihori, ā, he pai hoki mō ngā pūnaha tuku wai o te tāone.
Pēhanga Ingoa: PN ≤ 0.5 MPa (e rite ana ki te pēhanga o te pūnaha paipa PE hono), me te pēhanga mahi mōrahi 1.5 ngā wā o te pēhanga whakamātautau hiri (tae atu ki te 1.2 MPa) i runga i ngā paerewa o te ao, me te whakamātautau hiri pēhanga iti 28 KPa i runga anō i ngā paerewa ASME hei manatoko i te mahi hiri me te kaha o te takirere.
Te Pāmahana Whakahaere: -20°C ki te +40°C (me tutuki te pēhanga mahi e whakaaetia ana i ngā pāmahana rerekē ki ngā paerewa rauemi paipa PE e rite ana).
Diameter Ingoa (dn): E wātea ana i roto i ngā whakatakotoranga maha, tae atu ki te 32, 40, 50, 63, 75, 90, 110, 125, 160, 180, 200, 250, 315, 355, me te 400.
Ngā Paerewa
GB/T 15558.3-2008
ISO4437-4:2015
EN1555-4:2011
ASEME B 16.40:2013
Te Whakahaere me te Tirotiro
I te wā e whakamahi ana i ngā takirere, me hiki ake, ā, me whakatakoto mārire. Kāore e whakaaetia kia tukinga, kia pā rānei ki tētahi wāhanga o te tinana takirere hei ārai i te kino. I mua i te tāutanga, me tirotirohia te mahi hiri o te takirere. Me whakamahi te hau, te hauota rānei i te rauemi whakamātautau, ā, me uru ki ngā ihirangi tirotiro te mahi hiri maui, te hiri matau, me te hiri kati katoa, me tutuki i te paerewa GB/T13927-1992.
Tūnga Tāutanga
Me tāuta ngā takirere ki runga i tētahi turanga kua tino piri, ā, i te wā e tāuta ana, me tuwhera katoa te takirere.
Te Horoi Paipa
I mua i te honotanga o te takirere, me pupuhi rawa te paipa, me horoi hoki kia kore ai e uru te oneone, te onepu, me ētahi atu paru ki roto i te awa takirere, ka pā kino pea ki roto.
Tikanga Hononga
Me hono te takirere me te paipa polyethylene (PE) mā te hononga honohono-putanga, te hononga honohono-hiko rānei, ā, me whai pūmau i ngā "Ture Hangarau mō te Whakarewa i ngā Paipa Hauhanga Polyethylene" (TSG D2002-2006).
Te Tāutanga o te Ringaringa Tiaki
Kei te takirere he pūmau tiaki (tae atu ki te taupoki pūmau tiaki) me te kī whakahaere. Me whiriwhiri te roa tika o te pūmau tiaki i runga i te hohonutanga o te keri. I te wā e tāuta ana i te pūmau tiaki, me whakarite kia tino rite te ahunga pere i runga i te taupoki pūmau tiaki ki te ahunga whakatuwheratanga o te paipa PE me te whakatuwheratanga o raro o te pūmau tiaki, kātahi ka whakarite poutū te pūmau tiaki ki te taupoki whakahaere takirere, ka whakapiri kia mau.
;Te Mahi o te Takirere Pūhau
Mena he takirere momo hau rua, he takirere momo hau kotahi rānei te mea e whakamahia ana, ko ngā mahi whakahaere koia ēnei: Tuatahi, kati rawatia te takirere matua, kātahi ka whakatuwhera i te taupoki putanga o te takirere hau, kātahi ka whakatuwhera i te takirere hau mō te whakaputa hau; i muri i te otinga o te whakaputa hau, katihia te takirere hau ka taupokina te taupoki putanga. Kia mōhio: Ko te putanga o te takirere hau ka whakamahia anake mō te whakakapinga hau, te tauira, te hono rānei ki te mura. Kāore e whakaaetia kia whakamahia mō te whakamātautau pēhanga pūnaha, te pupuhi, te whakauru hau rānei, ki te kore ka kino pea te takirere, ka puta he aituā haumaru.
Ngā Whakaritenga Whakakī
Me whakakī anō te wāhi i waho o te ringaringa tiaki ki te oneone taketake, ki te onepu rānei, kaua he kōhatu, he poraka karāhe, he mea mārō rānei, kia kore ai e pakaru te ringaringa tiaki me te takirere.
Ngā Whakatakotoranga Mahi
Ka whakaaetia anake te whakamahi i te takirere i te wā e tuwhera katoa ana, e kati katoa ana rānei. Kāore e whakaaetia kia whakamahia hei whakahaere i te pēhanga, hei whakawhāiti rānei i te hau. I te wā e whakahaerehia ana, whakamahia te kī e rite ana. Ko te hurihanga ki te taha maui hei whakatuwhera, ko te hurihanga ki te taha matau hei kati.
