He mea nui te ratonga tā paipa rino JIS G3454 ERW i roto i te hanganga me te whakaputanga o ngā paipa rino ERW. Ko te JIS G3454 he Paerewa Ahumahi Hapanihi e tohu ana i ngā paipa rino waro mō te ratonga pēhanga pāmahana teitei. Ka hangaia te paipa rino ERW (whakarewa ātete hiko) mā te tukanga e whakamahanahia ai ngā taha o ngā pepa rino, o ngā rīpene rānei, ka honoa ngātahi i raro i te pēhanga, ka hanga he paipa kore hononga, he paipa kaha. He mea nui ngā ratonga tā e uru ana ki te whakaputanga o ngā Paipa Rino JIS G3454 ERW ki te whakarite i te kounga me te pono o ēnei paipa. Ko ngā ratonga tā e uru ana ki te whakamahinga o ngā mīhini pēhanga teitei hei hanga paipa ki ngā rahi me ngā whakaritenga e hiahiatia ana. Mā tēnei tukanga ka whakarite kia maeneene, kia tika hoki ngā pito o te paipa, me te matotoru pakitara rite tonu puta noa i tōna roa. Ko tētahi o ngā painga matua o ngā ratonga pēhi paipa rino JIS G3454 ERW ko te kaha ki te whakaputa paipa me te tika o ngā rahi me te pono o te whakarewa. Mā ngā ratonga tā ka taea te whakahaere pai ake i te tukanga hanga, me te whakarite kia tutuki i te paipa ngā paerewa me ngā whakaritenga e hiahiatia ana. Hei tāpiri, mā te whakamahi i ngā mīhini pēhanga teitei i te wā e tā ana i ngā mahi tā ka āwhina i te whakaputa i ngā paipa he tino kaha, he tino pakari hoki, e pai ai mō ngā momo mahi i roto i ngā ahumahi pēnei i te hinu me te hau, te hanga, me te motuka. Hei tāpiri, ka taea hoki e ngā ratonga pēhi paipa rino JIS G3454 ERW te whakaputa i ngā paipa maeneene, ataahua hoki. Ka taea e ngā mīhini e whakamahia ana i roto i ngā ratonga tā te whakakanapa me te whakapai ake i te mata o te paipa, ka hua ake he hua ataahua ake. He mea nui rawa atu tēnei mō ngā mahi e kitea ana, e kitea ana rānei ngā paipa, nā te mea ka whakarei ake i te āhua whānui, ā, ka whakarite kia kounga teitei te whakaotinga. Hei whakamutunga, ko ngā ratonga pēhi paipa rino JIS G3454 ERW he wāhanga nui o te tukanga hanga, e whakarite ana i te whakaputanga o ngā paipa kounga teitei me te pono mō ngā momo mahi ratonga pēhanga. Ka whakarite i te tika o te rahinga, te pono o te whakarewa, me ngā mata maeneene, e pai ai ēnei paipa mō te whānuitanga o ngā ahumahi me ngā whakamahinga.
