Tirotiro: I te nuinga o te wā, me tirotirohia ngā hanganga matū o ngā paipa rino mō te kawe wai, me whakamātautau kume, me whakamātautau papatahi, me whakamātautau pēhanga wai. Haunga ngā whakamātautau me whakahaere i ngā paipa rino mō te kawe wai, me whakamātautau whānui me te whakamātautau pānga hoki ngā paipa rino o GB5310, GB6479 me GB9948; he tino pakari ngā whakaritenga tirotiro hanga mō ēnei paipa rino e toru. He whakaritenga motuhake anō hoki tā te paerewa GB6479 mō te pakari pānga pāmahana iti o ngā rauemi. Haunga ngā whakaritenga whakamātautau whānui mō ngā paipa rino mō te kawe wai, me whakamātautau piko matao hoki ngā paipa rino o te paerewa GB3087. Haunga ngā whakaritenga whakamātautau whānui mō ngā paipa rino mō te kawe wai, me whakamātautau whānui me te whakamātautau piko matao ngā paipa rino o te paerewa GB/T8163 e ai ki te whakaaetanga. Kāore i te tino pakari ngā whakaritenga hanga mō ēnei paipa e rua pērā i ngā paipa tuatahi e toru. Hanga: Ko ngā paipa rino o ngā paerewa GB/T/8163 me GB3087 ka whakarewahia mā te oumu tuwhera, mā te kaitahuri rānei, ā, he nui ake ngā wāhanga poke me ngā hapa o roto. Ko te nuinga o te wā ka whakarewahia te GB9948 mā te oumu hiko. Ko te nuinga o ēnei kua tāpirihia te tukanga whakamahine i waho o te oumu, ā, he iti ake te hanganga me ngā hapa o roto. Ko ngā paerewa GB6479 me GB5310 tonu e whakarite ana i ngā whakaritenga mō te whakamahine i waho o te oumu, me te iti rawa o ngā wāhanga poke me ngā hapa o roto, me te kounga rauemi teitei rawa. Ko ngā taumata kounga hanga o ngā paerewa paipa maitai i runga ake nei kei te raupapa mai i te iti ki te teitei: GB/T8163
