Me hono e koe ngā paipa PE mō tētahi kaupapa whakamakuku, engari he puhoi te whakapiri, ā, ehara i te mea he kōwhiringa te whakarewa. Kei te moumou taima nui tō rōpū ki ngā hononga uaua ka ngawari te turuturu mena kāore i te tino tika te mahi.

Ko te kōpeketanga PP he momo hononga i hangaia mai i te polypropylene (PP) e hanga ana i te hiri ā-wai ki runga i ngā paipa polyethylene (PE). Mā te kōpeke ā-mīhini i te mowhiti hiri ki runga i te paipa i a koe e whakakī ana i te nati, mā te ringaringa te nuinga.

Ina kōrero ahau ki taku hoa a Mandla mō āna kaupapa i Āwherika ki te Tonga, ka huri te kōrero ki te tere me te pono. He maha ngā wā e mahi ana āna tīma i ngā wāhi tūmatanui ki te tāuta i ngā raina wai whakamakuku, i ngā raina wai taiwhenua rānei. Kāore e taea e rātou te utu mō ngā whakaroa, ngā hononga pakaru rānei. Koinei te wāhi eNgā hononga kōpeketanga PPHe tino huringa nui tēnei. He hangarau tino māmā, engari he tino whai hua, kua huri i te āhua o te hono i ngā paipa PE. Ko te mārama ki tēnei pūkenga miihini ngāwari te mea nui hei maioha ki tōna uara.

He aha te tikanga o te kupu PP i roto i ngā paipa?

Ka kite koe i ngā momo kirihou pēnei i te PVC, te CPVC, me te PP, ā, kāore koe i te tino mōhio ki ō rātou rerekētanga. Mā te whiriwhiri i te rauemi hē mō tētahi matū, mō tētahi pāmahana rānei, ka tere te pakaru, ka nui hoki te utu mō ngā pakaru.

I roto i ngā paipa, ko te PP te tikanga o te Polypropylene. He kirihou pakari, ātete wera, e mōhiotia ana mō tōna ātete matū tino pai. Nā tēnei he kōwhiringa tino pai mō ngā tono ahumahi, ngā raina matū, me ngā pūnaha wai wera.

Me kōrero tātou mō ngā rauemi. Ahakoa he pai te PVC mō ngā tono wai whānui, he kaha motuhake tō te PP. Ko tōna kaha nui ko tōna kaha ki te tu atu ki te tini o ngā matū—ngā waikawa, ngā kawakore, me ngā whakarewa ka ngoikore, ka whakangaro rānei i ētahi atu kirihou. I Pntek, ka whiriwhiri mātouPP kounga teiteimō ā mātou taputapu kōpeketanga nā te mea he tino pakari, he ātete hoki ki te pānga, he mea nui tēnei mō ngā hua katoa e whakamahia ana i te mara. Ka taea hoki e ia te whakahaere i ngā pāmahana teitei ake i te PVC paerewa. Ka tāpirihia hoki e mātou he whakaū ki tā mātou tauira PP kia tino ātete aiTe pirau o te hihi UVmai i te rā, e ārai ana i tōna pakarukaru i te roanga o te wā. Nā te arotahi ki te kounga o ngā rauemi i whakawhirinakihia ai ā mātou taputapu i roto i ētahi o ngā taiao tino uaua.

He aha ngā hononga PP?

Me hono ō paipa, engari me karo i te kāpia paru, i ngā taputapu whakarewa uaua rānei. Mā te whakamahi i ēnei tikanga tawhito ka whakaroa i tō kaupapa katoa, ā, me whai kaimahi whakangungu motuhake.

Ko ngā hononga PP he hononga i hangaia mai i te polypropylene e whakamahia ana hei hono i ngā paipa PP, PE rānei. Kei roto i ēnei ngā momo mō te whakarewa, engari ko ngā mea tino rongonui ko ngā hononga kōpeketanga, e hanga ana i tētahi hiri miihini kaha me te kore he wera, he kāpia, he taputapu motuhake rānei.

Ngā taputapu PPko ngā poraka hanga mō te waihanga i tētahi whatunga paipa maha-whakamahinga. Ahakoa ka taea e koe te hono i ngā paipa PP mā te whakamahi i te wera (te hononga pūtake, te hononga pūtake rānei), ko te whetu tūturu mō ngā hononga paipa PE ko teTe whakaurunga kōpeketanga PPKua arotahi mātou ki ēnei hononga i Pntek. Kei roto i ia hononga he pūnaha mohio o ngā wāhanga. Ina whakawirihia te nati ki te tinana, ka tīmata he tauhohenga mekameka. Ka ngau te "mowhiti piri" niho koi ki te paipa PE hei pupuri i te punga, kia kore ai e taea te kume. I taua wā anō, ka panaia e te "mowhiti pana" te "mowhiti-O" ki roto i te rūma, ka pēhi i te paipa. Ko tēnei mowhiti-O rapa pēhi te mea e hanga ana i te mea tino pai,hiri piri-pupuhiHe hoahoa māmā, he hoahoa kanapa hoki e taea ai e te tangata te hanga hononga kounga ngaio i roto i ngā hēkona.

Te Āhua o te Hononga Kōpeketanga PP

1. Nati:Ka whakakīkī hei whakahohe i te hiri.
2. Mowhiti Whakamau:Ka pupuri i te paipa kia kore ai e tōia ki waho.
3. Mowhiti Pana:Ka pana i te O-ring ki tōna tūranga.
4. Mowhiti-O:Te hiri rapa e aukati ana i te wai.
5. Tinana:Kei roto ngā wāhanga katoa, ā, e hono ana ki te paipa.

He aha te tikanga o te kōpeketanga i roto i te mahi paipa?

Kua rongo koe i te kupu "hononga pēhi" engari kāore koe i te tino mōhio me pēhea te mahi. Nā te kore mōhio ka uaua ki te whakamārama i ngā painga ki ō kiritaki, ki te whakawhirinaki rānei ki te hononga.

I roto i te mahi paipa wai, ko te kōpeketanga e pā ana ki tētahi tikanga hanga hiri mā te whakamahi i te kaha ā-ringa hei kōpeke i tētahi wāhanga hiri. Mā te whakakī i tētahi nati ka kōpeketia te mowhiti, te gasket rānei ki tētahi paipa, ka hanga he hononga ā-wai, kāore he matū, he whakarewa rānei.

He māmā noa iho, he kaha hoki te whakaaro o te pēhitanga. Engari i te whakamahi i te tauhohenga matū pēnei i te kāpia, i te whakarewa rānei i te kirihou ki te wera, kei te whakamahi koe i te kaha miihini noa iho. Whakaarohia te whakakī i tētahi pūtu. I a koe e whakakī ana i te nati i runga i te hononga pēhitanga, ka pēhia he hiri ngohengohe, ngāwari (he mowhiti-O i roto i tā mātou take) ki roto i tētahi wāhi iti, kuiti. Kāore he wāhi hei haere atu mō te hiri, nō reira ka tino pēhi ki te mata o te paipa me te tinana o te hononga. Ka hangaia e tēnei pēhanga he ārai e kore e taea e te wai te whiti. Ko te painga matua ko te māmā me te pono. Kāore koe e manukanuka mēnā kua maroke te kāpia, mēnā rānei kua wera te whakarewa. He hiri tūturu noa iho tēnei ka taea e koe te whakawhirinaki, ā, he tikanga e tino pai ana mō te hono i ngā paipa ngāwari, pakupaku rānei pēnei i te PE.

He aha ngā momo matua e rua o ngā hononga kōpeketanga?

Ka kite koe i ngā hononga pēhi mō ngā paipa parahi me ngā hononga rerekē mō ngā paipa kirihou, ā, ka whakaaro koe he aha i rerekē ai. Tērā pea kāore e angitu te whakamahi i tētahi hononga i hangaia mō te konganuku ki runga i te paipa kirihou.

Ko ngā momo matua e rua ko ngā paipa whakarewa me ngā paipa kirihou. Ko te momo paipa whakarewa he mowhiti whakarewa ngohengohe (ferrule) e ngau ana ki roto i te paipa. Ko te momo paipa kirihou he mowhiti hopu me te mowhiti-O rapa motuhake hei hiri.

He mea nui kia mōhio koe ki te momo e whakamahia ana. He mea motuhake te hoahoa ki te rauemi o te paipa. Mō ngā paipa konganuku pakari pērā i te parahi, he mowhiti parahi iti, he mowhiti parahi rānei kei roto i te hononga e kiia nei ko te ferrule. Ina whakakīia te nati, ka kuruhia tēnei ferrule ka ngau ki te mata o te paipa konganuku, ka hangaia te hiri. He tukanga kotahi tēnei e whakapēke tonu ana i te ferrule. Mō ngā paipa kirihou, pērā i ngā paipa PE e whakamahia ana i roto i te whakamakuku, he rerekē te huarahi. Ka whakamahia e ā mātou hononga kōpeketanga PP he pūnaha "wetewetehia". Ka hopukina te taha waho o te paipa e te mowhiti piri kirihou me ngā niho iti hei pupuri i a ia ki tōna tūranga. Kātahi ka kōpeketia he mowhiti-O rapa ngohengohe motuhake hei hanga i te hiri. Ka whakaratohia e tēnei hoahoa he kaha pupuri whakamiharo me te hiri tino pai me te kore e pakaru te paipa kirihou. Koinei te tikanga tino pai mō ngā pūnaha paipa PE.

Ngā Momo Hononga Pēhanga

Momo	Mō ngā Rauemi Paipa	Tikanga Hiri
Momo 1: Ferrule	Mea whakarewa (Parahi, Parahi)	Ka kuruhia he mowhiti whakarewa ki runga i te mata o te paipa.
Momo 2: Mowhiti-O	Kirihou (Polyethylene)	Ka hopukina te paipa e te mowhiti mau, ā, ka pēhia he mowhiti-O rapa.

Whakamutunga

Ngā hononga kōpeketanga PPHe otinga tere, kore taputapu hoki mō te hono i ngā paipa PE. Ka whakamahia e rātou te kaha miihini māmā o te mowhiti-O hei hanga i tētahi hiri pono, ātete-wai mō tētahi kaupapa.
