    Ngā Tohu Hua

     X42SSAWpaipaHe momo paipa hau māori e whakamahia whānuitia ana i roto i te umanga hinu me te hau. Ka hangaia mā te whakamahi i te tukanga whakarewa pewa i raro i te wai e whakaputa ana i ngā paipa kounga teitei me te pakari. He kaha teitei te paipa SSAW X42 me ngā āhuatanga matū tino pai, he mea tino pai mō ngā whakaritenga uaua o te kawe hau māori. Nā tōna ātete pai ki te waikura me te ngatata, koinei te whiringa tuatahi mō ngā kaupapa hanga paipa.

     ASTM A139Ko tētahi atu paerewa nui mō ngā paipa hau māori. E kapi ana tēnei whakatakotoranga i te paipa maitai honohono hiko (arc) he mea whakarewa tika, he mea porowhita rānei, e whakamahia ana mō te kawe i ngā hau, te mamaoa, te wai me ētahi atu wai. E mōhiotia ana te paipa ASTM A139 mō tōna pono me tōna mahi roa i raro i ngā āhuatanga mahi tino uaua. Kua hangaia ēnei paipa kia tū atu ki ngā pēhanga teitei me ngā piki me ngā heke o te pāmahana, kia pai ai mō ngā tono tuku me te tohatoha hau māori.

     EN10219He paerewa Pākehā tēnei e tohu ana i ngā tikanga tuku hangarau mō ngā wāhanga hanganga kōhao kua whakarewahia matao o te maitai kore-koranu me te maitai pai. Ahakoa kāore te EN10219 i hangaia mō ngā paipa hau māori, ko ōna whakaritenga pakari mō te pakari, te tika o ngā āhuatanga me ngā āhuatanga miihini he mea pai mō ētahi kaupapa paipa hau. Mā te whakamahi i ngā paipa e tutuki ana i ngā paerewa EN10219 ka taea te whakapai ake i te pono whānui me te roa o te mahi o tō pūnaha tohatoha hau māori.

    Kāore e taea te whakanui rawa i te hiranga o te whiriwhiri i ngā paipa hau māori kounga teitei. Ka taea e ngā paipa kounga iti, kounga iti rānei te whakararu i te taiao, te haumaru o te marea, me te pono whānui o ngā tuku hau. Nō reira, me whakatairanga ngā kamupene hau māori, ngā kaiwhakahaere paipa me ngā kaiwhakahaere kaupapa i te whakamahinga o ngā rauemi paipa kua whakamātauhia, kua roa hoki e whakamahia ana, pērā i te paipa X42 SSAW, ASTM A139 me te EN10219.

    Paipa SSAW

    Hei whakarāpopototanga,paipa hau māoriHe mea nui te whiriwhiri i ngā paipa hei hanga me te hoahoa. Ko ngā whakaaro kounga, pērā i te kaha o ngā rauemi, te ātete ki te waikura, me te tutuki i ngā paerewa ahumahi, me ārahi i te tukanga whakatau. Mā te whiriwhiri i ngā paipa pono me te whai ingoa pai, pērā i te paipa X42 SSAW, ASTM A139, me te EN10219, ka taea e ngā kaipupuri hea te whakarite i te oranga tonutanga me te haumaru o ngā hanganga kawe hau māori mō te wā roa.
