Nō nā tata nei, kua oti i tā mātou kamupene te whakaoti i tētahi puranga o ngā takirere pūrerehua DN800 rahi nui, ko ngā whakaritenga motuhake koia ēnei;

Tinana: WCB
Kōpae: WCB
Hiri: SS304+Karapi
Kākano: SS420
Nohoanga tango: 2CR13

Ka taea e NSEN te whakarato i ngā diameter takirere DN80 – DN3600 ki ngā kiritaki. Ki te whakatauritea ki ngā takirere kuaha me ngā takirere pōro o te rahi ōrite, he māmā te hanganga o ngā takirere pūrerehua diameter-rahi, ā, ka taea te whakapoto i te roa hanganga, te whakaiti i te taumaha. Ā, me huri noa i te 90° hei whakatuwhera me te kati tere, me te whakahaere ngāwari.

Ko ngā āhuatanga o te takirere pūrerehua e toru-āhua rerekē e whai ake nei;

③Mā te hoahoa poro mohio ka taea e te takirere te hiri aunoa, ka whakakīkī ake i te hiri, ā, ka taea te whakatika i ngā mata hiri, ā, kāore e taea te turuturu.

④He iti te rahi, he māmā te taumaha, he māmā te whakahaere, he ngāwari ki te tāuta.

⑤ Ka taea te whirihora i ngā taputapu hau me ngā taputapu hiko kia rite ki ngā hiahia o te kaiwhakamahi kia tutuki ai ngā hiahia o te mana mamao me te whakahaere hōtaka.

⑥Ka taea te whakakapi i ngā rauemi o ngā wāhanga kia urutau ki ngā momo pāpāho

⑦Momo hononga rerekē: anga whakarara, pūwero, whakarewanga pūmau.
