Nō nā tata nei, i te awheawhe Jinbin Valve, e rua ngā takirere pūrerehua hiko-toru-rahi te whānui, he DN1400 ngā whakatakotoranga me ngā rauemi Q235B kua oti te tirotiro katoa i te wheketere, ā, kua rite mō te tuku ki ngā kiritaki. Kua paahitia e ēnei takirere ngā whakamātautau pēhanga wai-pūmau tino pakari, kāore he turuturu puta noa, ā, he pai te mahi a ngā kaiwhakaoho hiko i muri i te whakatūnga. I tēnei wā, kei te whakaotihia te āhua o te mahi kia tino tika ai te whakamahinga i roto i te āhua kounga teitei.

He taputapu whakahaere matua tēnei takirere pūrerehua hiko-toru-ara, i hangaia mō ngā pūnaha tuku wai nui. Ko te tinana matua he mea hanga ki te maitai waro Q235B, he tino kaha te hanganga, he ātete pānga, he kaha hoki ki te pupuri i te pēhanga. He pai mō ngā āhuatanga mahi DN1400-diameter nui, e tutuki ai ngā hiahia tuku rere nui i roto i ngā āhuatanga pēnei i te tuku wai me te rerenga wai, ngā whatunga paipa ā-tāone, me te wai rere ā-umanga. He hanganga hiri toru-āhua te takirere, ā, he mea hanga te mata hiri ki ngā rauemi ātete-kakahu me te ātete-waikura, e kore e whakaiti noa i te kakahu i te wā whakatuwheratanga me te katinga, engari ka tutuki hoki te mahi hiri pumau kore-tūturu mō te wā roa, e pupuri ana i te hiri pono ahakoa i raro i ngā āhuatanga pēhanga teitei me te rerekētanga nui. He taputapu hiko teitei-mahi, e tautoko ana i te mana aunoa mamao me ngā aratau mahi ā-ringa i te papaanga, e taea ai te huri tika, te whakakotahitanga me te whakawhiti ahunga rere o ngā paipa toru-ara, e whakapai ake ana i te pai o te mahi pūnaha me te whakaiti i ngā utu mahi ā-ringa me te tiaki.

I te wāhanga tirotiro wheketere, ka whai pū te tīma hangarau i ngā paerewa ahumahi ki te whakahaere i ngā whakamātautau hiri wai-pūmau i runga i ngā takirere, me te kore e turuturu, e rerekē rānei te āhua puta noa, ā, ka tutuki te mahi hiri i te paerewa kore-turuturu. I taua wā anō, ka whakahaerehia he maha ngā wāhanga whakatuwheratanga me te kati i runga i ngā kaiwhakaoho hiko hei manatoko katoa i te tika o te whiu, te tere urupare, te tiaki rohe me ngā mahi tiaki taumaha, kia mau ai te mahi pumau i raro i ngā āhuatanga mahi uaua. I te wāhanga whakaoti āhua, ka whakahaerehia e ngā kaimahi he tirotiro whānui, he huri me te peita anō i ngā taipitopito pēnei i te paninga tinana takirere, te mata hiri flange, me ngā poraka mutunga kaiwhakaoho, kia mau ai te āhua me te mahi o te hua ki ngā paerewa, me te whakatutuki i ngā whakaritenga pakari a ngā kiritaki mō ngā taputapu ahumahi kounga teitei.

He maha ngā painga matua pērā i te rere o te wai i roto i te whānui, te whakawhiti ngāwari me te whakahaere aunoa, ā, he whānuitia te whakamahinga o ngā takirere pūrerehua hiko e toru-ara i roto i te tuku wai me te rerenga wai o te tāone, te maimoatanga paru, te wai e rere ana i roto i ngā tipu hiko, te tuku wai matū, te mahi whakarewa me te keri me ētahi atu mara. Ka taea e te takirere kotahi te whakakapi i ngā takirere pūrerehua tuku iho maha, ka whakangawari ake i te tahora o ngā paipa, ka whakaiti i te whakapaunga pūngao o te pūnaha me ngā utu tiaki i muri mai, ka waiho hei whiringa pai mō te whakapai ake atamai me te whai hua o ngā pūnaha wai nui.
