8. Ngā Pātai Auau (FAQ)

P1: He aha te rerekētanga i waenganui i te X65 me te X65MS?
A: He whakarerekētanga "ratonga kawa" a X65MS o te X65. He iti ake te waro (≤0.10%), he iti rawa te whanariki (≤0.002%), he kaha ake te whakahaere i te pakeketanga (≤248 HV), ā, me whai whakamātautau SSC/HIC e ai ki te NACE MR0175. Kāore te X65 paerewa e pai mō te H₂S mākū.

P2: He aha i whakamahia ai te Incoloy 825 hei utu mō te 316L, te duplex rānei mō te ratonga kawa?
A: He nui te nikara kei roto i te Incoloy 825 (38-46%), ā, he tino ātete ki te SCC me te SSC i puta mai i te pūhaumāota. Ka ātete hoki ki ngā waikawa whakaiti (hei tauira, te HCl) me te whanariki taketake – ngā āhuatanga ka kore ai e ranea te 316L me te duplex. Mō te ratonga kawa tino kino (te H₂S teitei + te pūhaumāota teitei + te S taketake), ko te Incoloy 825 te CRA iti rawa e whakaaetia ana.

P3: Ka taea te whakarewa i te whakakikoruatanga o Incoloy 825 ki a ia anō, ki te maitai waro rānei?
Āe. Ka taea te whakarewa i te Incoloy 825 mā te GTAW (TIG), GMAW (MIG), me te SMAW. Mō te hono i te whakakikorua ki te whakakikorua, whakamahia te whakarewa whakakī Alloy 82 / 82i (ERNiCr-3) Alloy 625 rānei (ERNiCrMo-3). Mō te hono i te whakakikorua ki te maitai waro (hei tauira, te whakakikorua whakarewa), whakamahia he paparanga waenga o te Alloy 309L, 625 rānei hei karo i te waimeha me te ngatata.

Q4: He ātete anō hoki te hononga roa ki te mahi kawa?
Āe. Ka whakarewaina te ara o roto ki te whakakī Incoloy 625 (he nui ake te Ni, Cr, Mo i te 825). Ka rite, he pai ake rānei te ātete waikura o tēnei whakakikorua whakarewa i te whakakikorua 825. Kua tirotirohia te whakarewa katoa mā te 100% NDT, ā, kua whakamātauria te pakeke.

Q5: He aha ngā tiwhikete e whakaratohia ana mō te ratonga kawa?
A: Ka tukuna e mātou ngā tiwhikete EN 10204 Momo 3.1/3.2 e whakauru ana i te tātari wera o te maitai tautoko, te pakeke, ngā pūrongo whakamātautau SSC me HIC (mēnā kua oti), me te rangahau pakeke whakarewa. Mēnā ka tonoa, ka tukuna e mātou he reta tutuki NACE MR0175.

Q6: He aha te roanga o te wā arahi mō te paipa whakakikoruatia ki te X65MS+Incoloy 825?
A: Ota tuatahi: 14-18 wiki (tae atu ki te hoko rauemi ratonga me te tohu mātauranga). Ota tuarua: 10-12 wiki. Tērā pea ka tāpirihia he 1-2 wiki e te tirotiro tuatoru.

Q7: Ka taea e Womic Steel te tuku paipa Inconel 625 hei utu mō te Incoloy 825?
Āe. Mō ngā āhuatanga kino rawa atu (te pāmahana teitei, te H₂S teitei, te pūhaumāota teitei), ka tukuna e mātou he paipa whakakikoruatia ki te X65MS+Inconel 625 (UNS N06625). He kaha ake te Inconel 625, ā, he pai ake te ātete ki te pakaru (PREN >45). Whakapā mai ki a mātou mō tētahi pepa raraunga motuhake.
