I ngā rā o mua, i hangaia ngā paipa ki ngā mea pēnei i te rakau, i te kōhatu rānei, kua kitea e te tangata he huarahi hou, he huarahi pai ake hoki hei hanga i tētahi paipa he kaha ake, he ngāwari ake hoki. Āe, i kitea e rātou tētahi huarahi matua ko te whakarewa. Ko te whakarewa he tukanga whakarewa e whakarewa ana i ngā konganuku e rua mā te whakamahi i te wera kia hanumi ai. Mā tēnei ka kaha ake ngā paipa i te mea he rakau, he kōhatu rānei.

 

He aha te meaPaipa Whakarewa?

Paipa whakarewa – Koinei te momo paipa whakarewa i hangaia mā te whakamahana i te pereti koiri wera, ka whakarewahia tuatahitia, kātahi ka hangaia mā te whakamahi i tētahi taputapu hurihuri. He tino tiaki te paipa o tēnei momo, ā, he whānui te whakamahinga i roto i ngā āhuatanga maha o tō tātou oranga. Hei tauira, ka whakamahia ngā paipa whakarewa ki ngā paipa hinu me te hau e tukuna ana te wahie, te ratonga tohatoha wai mā te whakawhiti wai ma ki ngā kāinga, tae atu ki te tukatuka motuka, waka rererangi rānei. E whakaatu ana tēnā i te whai hua me te pakari o ngā paipa whakarewa maitai.

 

Te Tīmatanga o te Paipa Whakarewa

I tīmata te tīmatanga o te kōrero mō ngā paipa whakarewa i te tau 1808. I tēnei wā, i whakamahia ngā mīhini mamaoa hei taraiwa i ngā mīhini maha. Heoi, i kitea wawetia e rātou me tu atu ngā paipa maitai i te pēhanga me ngā pāmahana teitei o te mamaoa e rere ana i ngā tūpuna. Nō reira, ka tīmata rātou ki te whakamātau ki te hangaPaipa whakarewa ERWe taea ai te tu atu i ēnei āhuatanga.

I te tīmatanga, tata kore e taea te hanga i ngā whakarewa pai. Ko ngā whakarewa o ēnei anga o mua te take o te hapa, ka hinga i raro i te pēhanga mamaoa tuatahi. Nō muri mai, ka ako te tangata ki te whakarewa pai ake. I ako rātou i ngā mahi hou hei āwhina i te whakarewa kia maeneene ake. I whakawhanakehia e rātou ngā tikanga hei whakapakari i te konganuku me te whakarewa i ngā hononga pono ake, hei whakapai ake i te pakari o ngā paipa.

 

Me pēhea tā tātou hanga paipa whakarewa i ēnei rā?

E mōhiotia ana i ēnei rā, mā te mahi nei ka homai he huarahi tino matatau ki a tātou ki te hanga paipa whakarewa. Ko tā mātou tikanga matua e mōhiotia ana ko te Electric Resistance Welding, ko te ERW rānei. Ka tukuna he iahiko kaha puta noa i te konganuku hei whakarewa, hei hanga i tētahi whakarewa totoka. He tere, he whai hua hoki tēnei tikanga, ā, ka puta he hononga paipa kounga teitei, pono, pumau hoki.

He wāhanga nui o te paipa whakarewa nui ngā paipa whakarewa; ko te kaha nui o ēnei mahi whakarewa ko tōna kaha whakaharahara. He kaha te pēhanga me te pāmahana o ēnei paipa whakarewa. He tino pai ngā paipa whakarewa mō te kawe i ngā wai, ngā hau, tae atu ki te hanga whare.

 

Te Hiranga o te Paipa Whakarewa

E mōhiotia ana hoki he iti ake te utu o ngā paipa whakarewa, nō reira, he painga nui tēnei nā te paipa whakarewa i ērā atu he kore hononga. He iti ake te utu i te hanga i ētahi atu momo paipa, ā, he māmā noa iho hoki te tukanga whakarewa. Koia te take he maha ngā wā ka whakamahia ngā paipa whakarewa e ngā ahumahi pēnei i te hinu me te hau, te hanga whare, te whakangao rānei i ēnei wā.

 

Te Tirohanga ki te Ao o Muri Mai

Ināianei, i a tātou e whakawhirinaki ana ki ngā paipa whakarewa hou i roto i tō tātou ao o nāianei, nui atu i mua, he mea nui kia kaua e ngaro tēnei rapunga mō te kounga me te auahatanga. He huarahi hei whakapai ake i te tukanga whakarewa. Hei tāpiri, me whakapai tonu tātou i te kaha me te pono o tēnei konganuku.
