| Ngā tukanga o ngā paipa/ngongo maitai kore waikura kua whakarewaina: |
| Ngā Kōwhiringa Whakaoti Mata: |
E rua ngā momo tohutohu paraihe e tukuna ana e mātou hei whakatutuki i ngā hiahia whakapaipai me ngā hiahia mahi rerekē:
Raina Makawe Tika (Paraihe Roa):
Ka rere te kiko i te roanga o te ngongo, ka hanga he āhua tirohanga maeneene, tonu hoki. He pai mō te whakapaipai ararewa, ngā ringaringa hoahoanga, ngā ngongo tāonga, me ētahi atu whakamahinga papai.
Raina Makawe Whakawhiti (Paraihe Whakawhiti):
Ka karapotia te porowhita o te ngongo e te kiko, he āhua ahurei mō ngā hononga pito-pōtae, ngā wāhanga hanganga, me ngā hoahoa whakapaipai ritenga.

| Whakamātautau Pakari o te Ngongo Kowiri tira 304 |
I SAKY STEEL ka whakahaerehia e mātou he whakamātautau pakari mō te taratara o ngā paipa kowiri tira hei whakarite kia maeneene, kia ōrite hoki te mata e tutuki ana i ngā paerewa o te ao. Ko te taratara o ngā paipa tētahi mea nui e pā ana ki te pai o te rere o te waikura, te ātete ki te waikura me te mahi whānui i roto i ngā tono nui.
Ka whakamahia e mātou ngā taputapu tino tika hei ine i ngā uara taratara o te mata, kia tutuki ai ngā paipa katoa i ngā hiahia o te kiritaki mō te maeneene me te whakaotinga. He pai rawa atu ā mātou paipa mō ngā ahumahi tukatuka kai matū moana me ngā ahumahi hanganga e tino hiahiatia ana te kounga o te mata.

| Whakamātautau Mata o te Ngongo Kowiri tira 304 |
He mea nui te āhua o ngā paipa kowiri tira mō te mahi me te āhua. I SAKY STEEL, ka tino whakahaerehia e mātou te kounga o te mata mā roto i ngā tukanga tirotiro matatau. E whakaatu ana te ahua i te whakataurite mārama i waenga i ngā paipa mata kino me ngā hapa e kitea ana me ā mātou paipa mata pai me te āhua maeneene me te ōrite.
Kāore he kapiti, he rakuraku, he tohu whakarewa i roto i ā mātou paipa kowiri tira, ā, he tino ātete ki te waikura me te pono. He whānuitia te whakamahinga o ēnei paipa i roto i ngā mahi matū moana me ngā mahi hanganga e tika ana kia tika te āhua o te mata.
| Whakamātautau PT Paipa Kowiri tira 304 |
Ka whakahaerehia e SAKY STEEL te whakamātautau werohanga PT i runga i ngā paipa me ngā wāhanga o te maitai kore waikura hei wāhanga o tā mātou tukanga whakahaere kounga tino pakari. He tikanga whakamātautau kore-whakangaro te PT e whakamahia ana hei kite i ngā hapa o te mata pēnei i te porosity o ngā kapiti me ngā whakaurunga kāore e kitea e te kanohi tahanga.
Ka whakamahia e ā mātou kaitirotiro whakangungu ngā rauemi wero me ngā rauemi whakawhanake kounga teitei hei whakarite i ngā hua tika me te pono. Ka whai ngā tikanga PT katoa i ngā paerewa o te ao me ngā whakaritenga a te kiritaki, hei whakapūmau i te haumaru me te mahi o te hua.

| Tirotiro Tuinga Whakarewa o te Paipa Whakarewa Kowiri tira 304 |
Mā te tirotiro hononga whakarewa paipa kowiri tira ka whakarite kia tutuki ngā hononga whakarewa katoa i ngā paerewa kounga me te haumaru e hiahiatia ana. Ko te tukanga tirotiro e arotahi ana ki te kimi i ngā hapa o te mata me roto pērā i ngā kapiti, te porosity, te whakaurunga para, te korenga o te hanumi, me te urunga kāore i oti. Ko ngā tikanga noa ko te tirotiro tirohanga, te whakamātautau urunga tae, te whakamātautau ultrasonic, me te whakamātautau radiographic. Ka tīpakohia ia tikanga i runga i te rauemi paipa, te matotoru o te pakitara, me ngā āhuatanga ratonga. Ka mahia ngā tirotiro katoa i runga i ngā paerewa o te ao pērā i te ASME, ASTM, me te ISO hei whakapumau i te pono me te mahi o ngā paipa whakarewa.

| Te Whakamahana Otinga-roto o te Paipa Kowiri tira |
Ko te whakamahana wairewa ā-roto o te paipa kowiri tira he tukanga maimoatanga wera tonu e whakamahia ana i te wā whakaputa hei whakatutuki i te hanganga moroiti austenitic ōrite me te whakarei ake i te ātete ki te waikura. Ka whakamahanahia te paipa ki te pāmahana whakamahana wairewa kua tohua, i waenga i te 1000°C me te 1150°C, kātahi ka whakamatao tere, me te whakamahi i te tinei wai, te whakamatao hau kaha rānei. Ka whakarewahia e tēnei tukanga ngā matūriki carbide me te aukati i te waikura intergranular, kia tutuki ai ngā āhuatanga miihini me te kounga o te mata i ngā paerewa o te ao. Ka whakapai ake te whakamahana wairewa ā-roto i te pai o te whakaputa me te pupuri tonu i te mahi hua.
