9. Ngā Pātai Auau (FAQ)
P1: He aha te rerekētanga nui i waenga i te paipa tuitui kua herea ki te whakarewa me te paipa kua whakarārangihia ki te miihini?
A: I roto i te paipa e herea ana ki te whakarewa, ka hangaia e te atanga he here horapa tauine-atomika (kaha kutikuti ≥300 MPa). Mā tēnei ka whakakorea katoatia te miro o te raina, te hinga, te wehenga rānei, he tūponotanga noa ēnei mō ngā paipa e whakarārangihia ana e te mīhini i raro i te huringa wera, i te pao pēhanga rānei.
P2: He aha i whakamahia ai te T91 (X10CrMoVNb9-1) kaua te P91 hei paparanga o waho?
A: He rite tonu te hanganga matū o te T91 me te P91. Ko te T91 te ingoa mō te ngongo tuitui (e whakamahia ana mō ngā ngongo poiha iti te whānui, hei tauira, ngā piko wera nui), ko te P91 ia e whakamahia ana mō ngā paipa nui te whānui. Ko te T91 te kōwhiringa tino pai mō te hanga piko-U wera nui me te piko-U wera anō.
P3: He aha te rerekētanga i waenga i te UNS N08028 (Alloy 28) me te UNS N08825 (Incoloy 825)?
A: He nui ake te Cr, Mo me te Cu o te koranu 28, ā, he pai ake te ātete ki te waikawa whanariki, te waikawa phosphoric me ngā taiao nui-hauora (PREN 38-40). He nui ake te nickel i roto i te Incoloy 825, ā, he ātete ake ki ngā waikawa whakaiti me te waikawa hydrofluoric. He iti ake te utu i te nuinga o te wā. Mō te tātaritanga reo motuhake, whakapā atu ki te tīma hangarau o Womic Steel.
P4: Ka taea te whakamahi i te paipa kua whakakikoruatia ki te P265GH + TP304L mō te wāhanga pāmahana-iti o te pōro?
Āe. He pai te kaha o te P265GH ki te pāmahana waenga me te āheinga whakarewa, ā, ka ātete te uhi o roto 304L ki te waikura mai i te hau haurehu (kei roto te waikawa whanariki). E taunakihia ana kia hiritia ngā pito o te ngongo i muri i te whakamātautau waikura hei ārai i te waikura i mua i te ratonga.
P5: Ka taea e koe te whakarato tiwhikete EN 10204 Momo 3.2 me te whakaaturanga a te hunga tuatoru?
Āe. He roa te mahi tahi a Womic Steel me SGS, BV, TÜV, DNV, ABS me LR. Ka taea e mātou te whakarite i te whakaaturanga whakamātautau a te hunga tuatoru (hei tauira, te tensile, UT) me te tuku tiwhikete Momo 3.2.
Q6: He aha te wā tuku noa mō ēnei huinga paipa whakakikoruatia?
A: Mō ngā ota tuatahi o ngā huinga paerewa, ko te tukunga he 60-90 ngā rā (tae atu ki te hoko rauemi, te whakaputanga hiato, te whakaotinga matao me te whakamātautau). Mō ngā huinga kua hangaia papatipu (hei tauira, P265GH+TP304L), ka taea te whakaiti i te wā arahi ki te 45-60 ngā rā.
