| Tukanga Whakaputa Paipa Kowiri tira |
Ko ngā mahi o te hanga paipa kowiri tira ko ngā mahi e whai ake nei: te whiriwhiri rauemi mata, te whakahinuhinu, te whakamahana, te huri, te horoi waikawa, te tango matao, te whakamātautau ultrasonic, me te takai whakamutunga. Mā ia mahi ka tutuki te paipa i ngā paerewa teitei o te kounga, te tika, me te whakaotinga mata.
| Whakamātautau Pakari o ngā Paipa Kowiri tira |
Ko te whakamātautau taratara mō ngā paipa kowiri tira he tukanga tirotiro nui e whakamahia ana hei aromatawai i te kounga o te mata o roto, o waho rānei o te paipa. Ko te taratara o te mata, e inehia ana i roto i te Ra (te toharite taratara), ka pā ki te pai o te rere, te ātete ki te waikura, me te ma—ina koa i roto i ngā ahumahi pēnei i te rongoā, te tukatuka kai, me te hanga haurua-ira. Mā te whakamahi i ngā taputapu tika pēnei i ngā ine mata, ka manatoko ngā kaitirotiro kei te tutuki te paipa i ngā whakaritenga e hiahiatia ana, pēnei i te Ra ≤ 0.8 µm, i te Ra ≤ 0.2 µm rānei, i runga i te tono. Mā te whakarite i te taratara o te mata tika ka pai ake te mahi a te hua, te ma, me te roa o te mau.

| Te Whakamātautau i te Au Eddy o ngā Ngongo Kowiri tira |
Ko te whakamātautau iahiko hurihuri he tikanga whakamātautau kore-whakangaro (NDT) e whakamahia ana hei kimi i ngā hapa o te mata me te taha tata o te mata i roto i ngā ngongo maitai kore waikura. He tino whai hua tēnei tikanga mō te tautuhi i ngā kapiti, ngā poka, me ētahi atu momo koretake me te kore e kino te rauemi. Mā te whakaoho i tētahi mara hikohiko ki roto i te ngongo me te aroturuki i ngā huringa o te rere o te iahiko hurihuri, ka taea e ngā kaitirotiro te arotake tere i te pono o te pakitara ngongo. He whānuitia te whakamahinga o te whakamātautau iahiko hurihuri i roto i te hanga ngongo maitai kore waikura me te whakarewa, inā koa mō ngā tono whakawhiti wera, poiha, me ngā taputapu. Ka whakarite i te pono o te hua me te tutuki i ngā paerewa ahumahi pēnei i te ASTM E426 me te EN 10246-3.
| Whakamātautau Ihirangi Ferrite |
He tukanga whakahaere kounga nui te whakamātautau i te ihirangi Ferrite mō ngā paipa kowiri tira, inā koa ko ērā i hangaia mai i ngā taumata austenitic, duplex rānei. Ka inehia e tēnei whakamātautau kore-whakangaro te nui o te wāhanga ferrite kei roto i te rauemi paipa, i te rohe whakarewa rānei hei whakarite i te ātete pai ki te waikura, te mahi miihini, me te pono o te whakarewa. Mā te nui rawa, te kore rānei o te ihirangi ferrite ka arahi pea ki ngā take pēnei i te pakaru waikura ahotea, te ngoikore rānei o te pakari. He maha ngā wā ka whakahaerehia te whakamātautau mā te whakamahi i ngā tikanga aukume (hei tauira, Ferrite Scope), ā, e tutuki ana i ngā paerewa pēnei i te ASTM E562, ISO 8249, AWS A4.2 rānei. I roto i ngā pūnaha paipa e whakamahia ana i roto i ngā taiao tino nui—pēnei i ngā papaaho moana, ngā oko pēhanga, me ngā tipu matū—he mea nui te whakahaere i te ihirangi ferrite mō te pono me te haumaru mō te wā roa.

| Otinga Ipurangi Te Whakamahana i ngā Ngongo Kowiri tira |
Ko te whakamahana otinga ipurangi he tukanga whakamahana tonu e whakamahia ana ki ngā ngongo kowiri tira i te wā e hangaia ana hei whakarei ake i te ātete ki te waikura, te kaha miihini, me te ōritetanga o te hanganga moroiti. I roto i tēnei tukanga, ka tere te whakamahana i ngā ngongo ki te pāmahana whakamahana - i waenga i te 1000°C me te 1150°C - ā, muri iho ka whakahaeretia te whakamatao, me te whakamahi i te wai, i te hau kore mahi rānei. Ka whakarewahia e tēnei maimoatanga ngā matūriki carbide ka whakahokia mai te hanganga austenitic, he mea tino nui mō ngā momo pēnei i te 304 me te 316. Mā te whakauru tika i tēnei taahiraa ki te raina whakaputa, ka whakarite te whakamahana otinga ipurangi i te kounga pumau, ka whakapai ake i te whai huatanga, ā, ka whakakorea te hiahia mō te whakamahana puranga motuhake.

| Whakamātautau PT o ngā Ngongo Kowiri tira |
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.
