Ngā Painga o te Hanganga me te Mahi o te Hua
1. Hanganga Ārai-Waikura Kowiri tira katoa
Ko ngā wāhanga matua pēnei i te tinana takirere, te pereti kuaha me te taupoki takirere he mea hanga katoa mai i te maitai kore waikura 304/316L. Kei roto i te rauemi 316L ngā huānga molybdenum, he ātete tino kaha ki te waikura ki ngā katote hauota, ngā tote waikawa-pūtake me ētahi atu mea waikura, e pai ai mō ngā āhuatanga waikura kaha pēnei i te miihini matū me te tango tote wai tote i te wai moana. Ka orohia pai te mata hei whakaiti i te ātete ki te whakatakotoranga me te rere o ngā mea, kia roa ake ai te ora o te taputapu.
2. Hoahoa Hiri Motuhake Nui-Diameter
Mō te whānui nui rawa atu o te DN1600, ka whakamahia he hanganga kuaha takirua ka taea te urutau. Ka whakatikatika te pereti kuaha i te rerekētanga wera me te rerekētanga tāutanga o te tinana takirere mā te hoahoa poro, ka tutuki ai te hiri rua-aronga kore-tātari. Ka pania te mata hiri mārō whakarewa ki te mata mārō koranu Stellite, me te pakeke tae atu ki te HRC45-50, he ātete ki te kakahu me te pāmahana teitei, ka whakaoti katoa i te mamae o te pakaru ngāwari o te hiri i roto i ngā takirere whānui nui.
3. Tukunga Whai Hua me te Mahi Watea
He pūnaha tuku miro trapezoidal tīwiri o waho te mea e rite ana ki te roa o te kakau takirere e whakaata tika ana i te whakatuwheratanga o te takirere, e whakahaere ana i te aroturuki me te tiaki i te papaanga. Mā te whakakotahitanga o te wira ringaringa me te taputapu whakaiti taputapu kutukutu ka tino whakaiti i te taipana whakahaere, ka taea e te tangata kotahi te whakatuwhera me te kati i te takirere whānui-rahi DN1600. Ka taea te tāuta i ngā kaiwhakaoho hiko, hau rānei hei urutau ki ngā pūnaha whakahaere aunoa me te whakatutuki i te whakahaere tika mamao.
4. Te Pono Nui me te Tiaki Iti
Ko te hoahoa o te awa rere tika he ātete rere ≤0.1 ina tuwhera katoa, ka whakaiti i te ngaronga pūngao pāpāho. Ko te hanganga hiri toru (te takai karāhe ngāwari + te mowhiti kowiri tira whakarewa + te repe) ka whakaiti i te mōrearea o te turuturu o waho o te kakau takirere. Ka whakamahia e te tinana takirere he hoahoa matotoru pakitara kua whakapakaritia, ātete ki te pēhanga teitei me te whakarerekētanga, e tutuki ai ngā whakaritenga pēhanga o ngā paipa whānui-rahi. He ngāwari te wetewete me te huihui i te hanganga whānui, ā, ka taea te tango katoa i te pereti kuaha me te kakau takirere me te kore e wetewete i te paipa, ka whakaiti i ngā utu tiaki i muri mai.
