Kei te raru koe i ngā turuturu, i ngā ngoikore rānei o tō pūnaha paipa? Ko te whakamahi i te hononga hē mō ngā paipa HDPE tētahi o ngā tino take o ngā pakaru nui o te pūnaha me ngā whakaroa o ngā kaupapa.

E toru ngā momo hononga matua e honoa ai ngā paipa HDPE:te whakakotahitanga o te papa, te whakakotahitanga hiko, me ngā hononga pēhi ā-ringa. Ka hangaia e ngā tikanga whakakotahitanga he hononga pumau, kotahi te kaha, he rite tonu ki te paipa tonu, engari ka tukuna e ngā hononga pēhi he hiri ā-ringa ka taea te tango.

Ko te mōhio ki ngā ingoa o ngā taputapu he tīmatanga noa iho. E mārama ana te kaiwhakahaere hoko matatau pērā i a Carlos ko te tohungatanga tūturu kei roto i te mōhio ko tēhea taputapu hei whakamahi mō tēhea āhuatanga. Mā tēnei mōhiotanga ka tiakina tō haumitanga, ka whakarite i te pono o te kaupapa, ā, ka hanga ingoa mō te pono.

Me pēhea te hono i ngā paipa HDPE ki a rātou anō?

Kei te raru koe i ngā hononga paipa uaua, kāore rānei e pono? Ko te hononga kino te hononga ngoikore rawa atu o tētahi pūnaha paipa, e tatari ana kia puta he raruraru ā muri ake nei.

Ka honoa ngā paipa HDPE mā te whakarewa wera (te whakakotahitanga o te pito, te whakakotahitanga hiko rānei) hei hanga hononga pumau, ātete turuturu, mā te whakamahi rānei i ngā hononga kōpeketanga miihini mō ngā diameter iti ake, ngā hononga rangitahi rānei, kāore e hiahiatia he taputapu motuhake. He rerekē te mahi a ia tikanga.

Mai i aku wheako ki Pntek, kua kite ahau i te huarahi e penapena ai te wā me te moni i te papaanga mā te whiriwhiri i te tikanga hononga tika. Ina āwhina a Carlos i tētahi kaimahi kirimana ki te whiriwhiri i waenga i tētahi hononga pēhi māmā mō tētahi whakatikatika iti me te hononga honohono mō tētahi paipa nui, ehara i te mea ko tētahi wāhanga anake tāna e hoko ana; kei te hoko ia i tētahi otinga e whakarite ana i te angitu mō te wā roa.

Whakakotahitanga o te Pūtu

Koinei te tikanga tino noa mō ngā paipa HDPE whānui. He māmā noa te tukanga. Ka pupuri te mīhini motuhake i ngā pito paipa e rua kia tino tika te tūnga. Ka whakatakotoria he pereti whakamahana ki waenganui i a rāua, ka whakarewahia ngā pito ki tētahi pāmahana motuhake. Ka tangohia te pereti, ā, ka pēhia ngā pito rewa i raro i te pēhanga whakahaere. Ka whakamataohia kia hanga he wahi paipa kotahi, tonu. He ātete rawa tēnei hononga, ā, he kaha rite tonu ki te paipa taketake.

Te whakakotahitanga hiko

He tino pai tēnei tikanga mō ngā whakatikatika, mō ngā wāhi kuiti rānei e kore e uru te mīhini honohono. Kei roto i ngā hononga honohono hiko he koiri waea. Ka whakauruhia ngā pito o te paipa ki roto i te hononga, ā, ka tukuna he iahiko hiko e te tukatuka honohono hiko ki ngā waea. Ka whakarewahia e te wera o ngā waea te roto o te hononga me te waho o te paipa, ka honoa ngātahi hei hononga pakari, pakari.

Ngā Hononga Kōpeketanga Mīhini

Mō ngā diameter iti ake (i raro iho i te 4 inihi, i te 110mm rānei), he otinga pai, he māmā hoki ngā hononga kōpeketanga. Kāore e hiahiatia he taputapu motuhake. Ka pana noa koe i tētahi nati me tētahi mowhiti pupuri ki runga i te paipa, ka whakauru i te paipa ki roto i te tinana hononga, ka whakau i te nati. Ka kōpeke tēnei i tētahi mowhiti-O hei hanga i tētahi hiri ā-wai. He tere, he ngāwari, ā, ka taea e tetahi kaimahi te mahi.

He pai ake te HDPE i te PVC?

Kei te tautohetohe koe i waenga i te HDPE me te PVC mō tō kaupapa e whai ake nei? Mā te whiriwhiri rauemi hē ka raru pea te tāutanga, ā, ka kore e tutuki i te pūnaha ngā tumanakohanga mahi.

Kāore tētahi o ēnei i te 'pai ake' i te ao whānui. He pai ake te HDPE mō tōna ngāwari, tōna ātete ki ngā matū, me te roa o te rewa-huka, he mea tino pai mō ngā whakaurunga kore-awa me ngā āhuatanga uaua. He pai ake te PVC mō tōna pakari, tōna kaha kume teitei, me te utu iti, koia te mea tino pai mō ngā puna wai me ngā tono pēhanga.

Hei kaiārahi mō Pntek, he kamupene e tino matatau ana ki te PVC, kua kite ahau i ngā kaupapa maha e tuku ana te PVC i te taurite tino pai o te mahi me te uara. Heoi, ko au te tuatahi ki te whakaae ko te HDPE te taputapu tika mō te mahi. E mōhio ana te tohunga pērā i a Carlos ko te huarahi pai ki te mahi ki āna kiritaki ko te ārahi i a rātou ki te rauemi tino pai mō ā rātou hiahia, kaua e pana noa i tētahi hua ki runga ake i tētahi atu.

Ngāwari vs. Pakari

Ko te rerekētanga tino kitea ko te ngāwari. Nā te kaha o te HDPE ki te piko ka taea te tāuta ki ngā kokonga me te kore he taputapu tāpiri, ā, he mea tino pai mō te tāutanga kore-awa (te kukume mā roto i te whenua). He tino pakari te PVC, ka hoatu he kaha kurupae pai mō te tanu, ā, ka ārai i te totohu i runga i ngā oma roa, tika.

Te Tikanga Whakauru me te Utu

He mea nui tēnei mā Carlos me āna kiritaki. Ka honoa te PVC ki ngā paninga māmā, iti te utu me te sima whakarewa, ki ngā pito pere rānei kua herea ki te gasket. He māmā noa iho ngā taputapu, ā, he tere te mahi. Me whakamahi ngā taputapu whakarewa motuhake, utu nui, me ngā kaiwhakahaere whaimana mō te HDPE, ka piki ake te utu me te uaua o te kaupapa tuatahi. Mō te utu rauemi, he iti ake te utu o te PVC i te HDPE mō te akomanga pēhanga kotahi.

Kei te inehia te HDPE i roto i te OD, i te ID rānei?

Tērā pea ka raru te kaupapa katoa o tō kaupapa mēnā ka hē te tono i te paipa? Mā te kore mārama ki te ine i te paipa HDPE ka kore e hototahi ngā paipa me ngā taputapu, ka moumou taima, ka moumou moni hoki.

Ko ngā inenga o ngā paipa HDPE e ahu mai ana i te Diameter o Waho (OD) kua whakahaeretia. He mea nui tēnei nā te mea me tino ōrite ngā mata o waho o te paipa me te taunga mō ngā tikanga hononga hanumi kia angitu ai te whakarewanga.

He āhuatanga hangarau tēnei e wehewehe ana i te hunga tauhou mai i te hunga ngaio. Ina kōrero ahau ki tētahi kaiwhakahaere hoko pēnei i a Carlos, ā, ka tohua e ia te paipa mā tōna OD me te SDR, e mōhio ana ahau kei te mahi tahi ahau me tētahi tohunga. E mārama ana ia ehara tēnei tika i te tau noa i runga i tētahi pepa whakaritenga; koia te kī ki tētahi pūnaha pono, kāore he turuturu. Ka rerekē te whānui o roto (ID) i runga i te matotoru o te pakitara, engari ka noho tonu te OD mō tētahi rahi paipa kua whakaritea.

He aha te mea nui o te diameter o waho

Ka mahi te hanumi wera mā te whakarewa i te mata o waho o te paipa me te mata o roto o te hononga (te mata o waho rānei o tētahi atu paipa). Kia pai ai tēnei, me tino tika te tūnga o ngā mata. Mā te pupuri i te pumau o te OD, ka whakarite ngā kaihanga kia uru tetahi paipa o tētahi rahi ki tētahi hononga, ki tētahi mīhini hanumi rānei e rite ana, ahakoa te nui o te pēhanga.

Te Mārama ki te SDR (Ōwehenga Ahu Paerewa)

• He aha te mea:Ko te SDR te ōwehenga o te diameter o waho o te paipa ki te matotoru o tōna pakitara.
• Tātai:SDR = OD / Matotoru o te Pakitara
• Te tikanga o tēnei: A raroKo te tau SDR he tikangamatotoru akepakitara paipa. Ka taea e te pakitara matotoru te tu atu i te pēhanga teitei ake. Hei tauira, he matotoru ake te pakitara o te paipa SDR 11, ā, he teitei ake te whakatauranga pēhanga i te paipa SDR 17 o te rahi ōrite. Me mōhio a Carlos ki te OD me te SDR e hiahiatia ana hei tono i te paipa tika mō ngā hiahia pēhanga a āna kiritaki.

He aha te momo hononga e whakamahia ana i roto i ngā paipa HDPE?

Kei te rapu koe i tētahi hononga paipa ka taea e koe te tanu, ka wareware? Ko te wehi kei turuturu mai ngā hononga kua tanumia he āwangawanga nui mō ngā kaimahi kirimana me ngā kaipupuri pūnaha.

Ko te hononga matua, te hononga kaha rawa atu hoki e whakamahia ana mō ngā paipa HDPE ko te hononga honohono. Mā tēnei tukanga whakarewa wera ka hangaia he hononga kotahi (kore hononga) e kore e turuturu, ā, he kaha ake i te paipa tonu.

He mea nui te ariā o tētahi pūnaha "monolithic". Ko tōna tikanga kei te hanga koe i tētahi paipa roa, tonu, kāore he hononga miihini ka taea te wetekina, te pakaru rānei i roto i te wā. Mō tētahi kaihoko pēnei i a Carlos, he painga whakataetae nui te kaha ki te tuku i tētahi pūnaha e whakakore ana i te mōrearea o te pakaru o ngā hononga. Koinei te kupu whakaari whakamutunga mō te pono mō te wā roa.

Te Waihanga i tētahi Pūnaha Ārai-Tuku

Kāore te hononga honohono-tua i rite ki te hononga piri, ki te hononga kua herea rānei; he hanganga anō ia o te rauemi tonu. Ka whakaranua ngā mekameka pūmua mai i ngā pito paipa e rua i roto i tō rātou āhua rewa, ka whakamatao kia kotahi te wahi totoka. Ko te poro iti e hanga ana i roto, i waho hoki o te paipa he tohu tirohanga mō te angitu o te whakarewa. He tino whakauru tēnei hononga kia mau tonu ai te ngāwari me te kaha o te paipa.

He aha tēnei te Paerewa Koura

He tino pono tēnei momo hononga, ā, koinei te paerewa mō ngā tono nui pēnei i ngā raina tohatoha hau māori, ngā puna wai pēhanga teitei, me te kawe matū ahumahi. He hononga ā-ia anō tōna, arā, kāore e taea te wehe i raro i te pēhanga, i te nekehanga whenua rānei. Mā tēnei ka kore e hiahiatia he poraka pana utu nui, he here rānei e hiahiatia ana mō te maha atu o ngā pūnaha paipa, ka whakaitihia ake ngā utu tāutanga me te uauatanga.

Whakamutunga

Ka whakawhirinaki ngā pūnaha HDPE ki te hanumi, ki tengā hononga kōpeketangaMā te hanumitanga o te papa ka hangaia te hononga tino kaha, ātete turuturu. Ko te kōwhiringa i waenga i te HDPE ngāwari me te PVC pakari, iti te utu, e whakawhirinaki katoa ana ki ngā hiahia motuhake o te kaupapa.
