Ko te pukapuka ā-ringa 304 kowiri tiratakirere kēti maripiHe takirere whakahaere matua motuhake tēnei mō ngā paipa kawe paru maina. He 1.6MPa te whakatauranga o te pēhanga ingoa, e wātea ana i roto i ngā rahi paerewa DN100, DN300 me te DN350, e tika ana mō ngā āhuatanga mahi me te pāmahana reo ≤ 100℃. I hangaia mō te keri paru me ngā matūriki totoka me ngā āhuatanga horoi kaha, ka whakatauhia e tēnei takirere ngā mamae ahumahi noa o ngā takirere tuku iho pērā i te aukati pinepine, te pakū nui me te rahunga hiri. Me te mahi pumau me te pono, kua waiho hei taputapu whakahaere wai pai mō ngā kaupapa tukatuka kohuke maina me te kawe paru o te ao, he tino urutau ki ngā taiao mahi keri uaua.

He hoahoa rauemi ngaio me te hanganga o tēnei takirere kua whakaritea mō te mahi paru. Ko te tinana takirere maitai kore waikura 304 e whakarato ana i te ātete tino pai ki te waikura me te mahi ārai-horoi, e ātete ana ki te horo me te kino i puta mai i ngā poke kohuke i roto i te paru, me te karo i ngā raruraru waikura me te poka o ngā takirere noa. Ko te hanganga mata angiangi me te koi ka taea te tapahi maeneene i ngā toenga totoka me ngā poke muka i roto i te reo, kia kore ai e araia te whakatuwheratanga me te kati me te kore e aukati i ngā rauemi. Mā te whakamahi i te taraiwa ringaringa-ringa parakore, kāore e hiahiatia he motuka hiko, he puna hau, he taputapu hiko āwhina rānei. Ko te mahi ngāwari me te pono i te papaanga e kore e pāngia e te motuhanga hiko, e te korenga rānei o te tuku hau, e whakarite ana i te mahi paipa pumau i te tau katoa.

He pai rawa atu te mahi hiri me te ngāwari o te whakaurunga. He hanganga hiri horoi-ā-unoa tōna, ka taea e te takirere te waru aunoa i ngā putunga paru me ngā toenga kohuke i runga i te mata hiri i te wā e tuwhera ana, e kati ana hoki, kia mau tonu ai te mata hiri ma, kia roa ai te hiri kia piri, kia kore ai e turuturu te wai. Mā te hononga ā-pātene paerewa ka taea te tāuta, te wetewete me te tiaki ngāwari, he pai hoki, he pai mō ngā whakatakotoranga paipa whaiti me te uaua i roto i ngā maina o raro whenua, ngā maina tuwhera me ngā rūma papu. Me te whakatauranga pēhanga 1.6MPa, ka tutuki katoa i ngā whakaritenga pēhanga o ngā paipa pēhanga reo me te iti mō te kawe paru maina me te tukunga paru.

I roto i te whakamahinga mahi, ka whakaitihia e tēnei raupapa o ngā takirere kuaha maripi ngā utu whakahaere me te whakapai ake i te whai huatanga mō ngā umanga keri. He iti noa te wāhi paipa e nohoia ana e te tinana takirere kiato, he pai te urutau ki ngā kaupapa keri hou me ngā kaupapa whakahou paipa tawhito. Ka whakaitihia e te hanganga taraiwa ā-ringa ngā utu hoko me te tiaki taputapu me te kore e hiahiatia he pūnaha whakahaere hiko uaua. Ko tōna tere rahunga tino iti ka whakaiti i te auau tiaki me ngā mate kati whakaputa. Ka hipoki i ngā whakatakotoranga maha DN100, DN300 me DN350, ka whakataurite te takirere i ngā paipa paru me ngā tere rere rerekē. Ka tautoko i te whakaritenga nui me te tuku papatipu me te tuku pumau hei whakatutuki i ngā tono hoko o ngā kaupapa keri o te ao.

Ko ngā takirere kuaha maripi ā-ringa katoa he mea hanga kia rite ki ngā paerewa ahumahi o te ao. Ka whakamatautauria ia takirere kia pakari te wai, kia tirotirohia te hiri me te manatoko mahi i mua i te tukunga kia mau ai te kounga me te pono. Hei takirere kati utu-whai hua mō ngā āhuatanga paru, he whānuitia te whakamahinga i roto i te tātaritanga o te konganuku, te kawe paru me te maimoatanga paru i roto i te pāmahana reo 100℃. Ka whakaratohia e mātou he hua paerewa, he ratonga whiriwhiri ritenga me ngā otinga whakahaere wai paipa katoa mō ngā umanga miihini keri B-end o te ao, hei huarahi pai ake hei whakakapi i ngā takirere tuku iho mō ngā āhuatanga mahi paru.
