Tērā pea ka pakaru te mata o te ngongo i ētahi mahi piko uaua. He mea whakarewa ngā taputapu, he mea whakarewa ngā paipa, ā, i ētahi wā, kāore e taea te karo i ngā karawarawa, i ngā rakuraku rānei. Getty Images
He māmā noa te piko angitu mō te maha o ngā mahi hanga ngongo, inā koa ka whakamahia ngā piko totoro hurihuri hou. He huinga taputapu katoa – ngā mate piko, ngā mate horoi, ngā mate whakapiri, ngā mate pēhanga me ngā mandrel – ka karapotia, ka herea hoki te ngongo i ngā mata o roto, o waho hoki kia rere ai te konganuku ki te wāhi e tika ana kia rere i te wā e piko ana. Mā tēnei, me te whakamahi tahi me tētahi pūnaha whakahaere hou, ka puta he hua pai mō ngā piko ngāwari ki te whakaōrite. Ehara i te mea he tino pono, nā te mea me tika te whakatūnga me te whakahinuhinu i te angitu, engari i roto i te nuinga o ngā wā, he piko pai te hua, i ia wā, i ia rā.
Ina tūtaki koe ki ngā piko uaua, he maha ngā kōwhiringa a ngā kaihanga. Ko ētahi mīhini kume waea hurihuri he mahi hiki i te whāriki e whakarato ana i te kaha pana hei āwhina i te kaha kume waea. Hei tāpiri atu ki tēnei, he maha ngā rautaki a ngā kaihanga taputapu mō te whakatau i ngā piko uaua, pēnei i te whakanui ake i te roa o te rawhi, te miihini rānei i tētahi raupapa o ngā niho i runga i te mata pa o te rawhi. Ka nui ake te waku o ngā rawhi roa; ka ngau ngā niho ki te mata o te ngongo. Ka whakaratohia e ngā mea e rua he pupuri taapiri hei pupuri i te ngongo kei paheke i te wā e piko ana.
Ahakoa ngā āhuatanga motuhake, ko te whāinga he whakaputa i ngā wāhanga e tutuki ai ngā hiahia o te kiritaki. I te nuinga o te wā, he iti noa te rerekētanga o ngā wāhanga, ā, he mata maeneene. Heoi, ehara tēnei i te mea pakari. Mō ngā ngongo e huna ana i te tirohanga, ka taea e ngā kiritaki te aro ki te āhua porowhita o ngā ngongo porowhita, te papatahi nui o ngā ngongo tapawhā, tapawhā rānei, te paku kikī, te tohu miihini rānei i te taha o roto o te piko. Ko te nuinga o tēnei ka taea te ine hei ōrau rerekētanga mai i te piko pai, nō reira me rapu he aha te mea e tino hiahiatia ana e te kiritaki. Ko ētahi tāngata e pai ana ki te utu nui mō te piko taketake, ko ētahi e pai ake ana ki te piko iti ake te utu me ngā hapa kitea.
I ētahi wā ka tohua e ngā kaihoko he tuke kāore e tino uaua ki te hanga, he mea hanga ki tētahi rauemi ngohengohe ngawari me te matotoru o te pakitara e ranea ana hei totoro i te taha o waho o te tuke me te kore e pakaru, engari kāore i te tino nui kia honoa ki roto o te piko. I te tīmatanga he rite ki tētahi piko noa iho, engari kātahi ka whakakitea e te kaihoko tētahi paearu whakamutunga: kāore he tohu. He ataahua te taupānga ki te titiro, nō reira kāore ngā kaihoko e aro ki tētahi kino mai i te taputapu.
Mena ka puta he tohu miihini i te piko whakamātautau, e rua ngā kōwhiringa a te kaihanga. Ko tētahi ko te mahi i tētahi atu mahi hei whakakanapa i te hua kua oti hei tango i ngā tohu taputapu katoa. Ae, ka taea te angitu o te whakakanapa, engari ko te tikanga he nui ake te whakahaere me te nui ake o te mahi, nō reira ehara i te mea he kōwhiringa iti te utu.
Ko te tango i ngā pakaru he mahi tango i te mata o te taputapu maitai. Ka mahia tēnei mā te hanga taputapu mai i ngā pūmua hangai taumaha, mā te hanga rānei i ngā whakaurunga taputapu mai i ēnei rauemi.
He rerekē ngā rautaki e rua i te tikanga tuku iho; he maha ngā wā ka hangaia ngā taputapu piko ki ngā koranu whakarewa anake. He iti noa iho ngā rauemi ka taea te tu atu ki ngā kaha piko me te hanga i tētahi ngongo, i tētahi paipa rānei, ā, kāore i te tino pakari ēnei. Heoi, e rua o ēnei kirihou kua noho hei rauemi noa mō tēnei tono: ko Derlin me Nylatron. Ahakoa he tino kaha te pēhi o ēnei rauemi, kāore i te rite te pakeke ki te maitai taputapu, koia te take kāore e waiho he tohu. He hinu whakahinuhinu taiao anō hoki ō rātou. Nā ēnei āhuatanga e rua, he onge te whakakapi tika o ngā taputapu atraumatic mō ngā taputapu paerewa.
Nā te mea kāore ngā pokepokea aira e hanga i ngā kaha waku e rite ana ki ngā pokepokea aira rino, he maha ngā wā ka hiahiatia he porowhita piko nui ake mō ngā wāhanga e puta mai ana, ā, kua hangaia hei tautoko i ngā here roa ake i ngā hoahoa pokepokea aira. E hiahiatia tonutia ana ngā hinu whakahinuhinu, ahakoa he iti noa iho te rahinga. Ko ngā hinu whakahinuhinu wai te mea pai rawa atu hei ārai i ngā tauhohenga matū i waenga i te hinu whakahinuhinu me te taputapu.
Ahakoa he iti te roa o te ora o ngā taputapu katoa, he poto ake te roa o te ora o ngā taputapu kore-kino i ngā taputapu tuku iho. He mea nui tēnei hei whakaaroaro ina whakahuatia ana tēnei momo mahi, nā te mea me whakawhiti pinepine ake ngā taputapu. Ka taea te whakaiti i tēnei auau mā te whakamahi i ngā whakaurunga polymer e piri ana ki ngā tinana taputapu maitai me ngā here miihini, e roa ake ana te ora i ngā taputapu i hangaia katoatia ki te polymer.
He pai ngā pokepokea kore-kino mō te hanga rino, te kowiri tira, te konumohe me te parahi, ā, he rerekē ngā whakamahinga noa i runga i te rauemi. He pai ngā whakamahinga kai me te inu mō ngā taputapu kore-kino. Ko te mea pai, he maeneene rawa ngā paipa mō te tukatuka kai, inu rānei. Ko ngā karawarawa, ngā pakaru, ngā karawarawa rānei e toe ana ki te mata o te paipa, o te paipa rānei, ka kohia he paru, ka noho hei wāhi whakatupu huakita.
Ko ētahi atu whakamahinga noa ko ngā wāhanga pania, whakakikoruatia rānei. Ko tētahi whakaaro hē noa ko te tukanga paninga, whakakikorua rānei e whakakī ana, e huna ana rānei i ngā hapa. He tino angiangi ngā paninga me te whakakikorua, ā, ko te nuinga o te wā ka aro atu ki tētahi āhua kanapa whakaata. Mā ēnei mata ka whakanuia ngā hapa o te mata, kaua e huna, nō reira me mahi ngā mahi whakatūpato.
I te tau 1990, ko Tube & Pipe Journal te maheni tuatahi i whakatapua ki te mahi ki te umanga paipa whakarewa. I ēnei rā, koinei anake te pukapuka i Amerika Te Raki i whakatapua ki te umanga, ā, kua noho hei puna mōhiohio tino pono mō ngā tohunga paipa.
