He aha te Inconel 625 Seamless Paipa?
Inconel 625 (UNS N06625,W.Nr. 2.4856) he koranu nikara-kromium-molibdenum me te niobium tāpiri. Ka mahi tahi te niobium me te molibdenum ki te whakapakeke i te anga koranu, ka nui te kaha me te kore e hiahiatia he maimoatanga wera whakakaha. He mea nui tēnā — ko te tikanga ka taea e koe te whakarewa me te whiwhi tonu i te kaha katoa me te kore he maimoatanga wera tāpiri i muri i te whakarewa.
Ko te tikanga o te paipa tuitui kore he hononga whakarewa i te roanga. Ka hangaia mā te wero i tētahi pereki totoka ka hurihia, ka tōia rānei kia rite ki te rahi. Ko te tikanga o te kore hononga whakarewa kāore he ngoikore, kāore he mōrearea o te waikura o te hononga, ā, he pai ake te kaha o te pēhanga. Koia te take he pai ngā paipa tuitui kore mō ngā tono nui ina kore e taea te rahunga.
Ka mahi te paipa Inconel 625 tui kore mai i ngā pāmahana cryogenic tae noa ki te 982°C (1800°F). Ka ātete ki te pakaru o te rua, te waikura kapiti, me te pakaru o te ahotea chloride - e toru ngā mea e patu ana i ngā paipa kowiri tira noa i roto i ngā mahi moana me ngā mahi matū.
Te Hanganga Matū
Ko te hanganga te mea e pai ai te mahi a Inconel 625. Anei te wehewehenga:
| Huānga | Taumaha % |
| Nikara (Ni) | 58.0% iti rawa (toenga) |
| Konukōmiuma (Kr) | 20.0 – 23.0% |
| Molibdenuma (Mo) | 8.0 – 10.0% |
| Niobium + Tantalum (Nb+Ta) | 3.15 – 4.15% |
| Rino (Fe) | 5.0% te mōrahi |
| Manganēhi (Mn) | 0.50% te mōrahi |
| Hiraka (Si) | 0.50% te mōrahi |
| Waro (C) | 0.10% te mōrahi |
| Koparata (Ko) | 1.0% te mōrahi |
Ko te nui o te nikara (58%+) te mea e kore ai e pakaru te waikura i te ahotea o te konukōre. Ko te molibdenum (8-10%) he ātete pai ki te waikura o te rua me te kapiti i roto i te wai moana me ngā mea kei roto he konukōre. Ko te niobium (3.15-4.15%) ka whakapakari i te wairewa totoka.
Ngā Āhuatanga Mīhini
I roto i te āhua whakawerawera, ka tukuna e te paipa Inconel 625 tui ngā āhuatanga hangarau e whai ake nei:
| Taonga | Uara |
| Kaha Kume (Whakamutunga) | ≥827 MPa (120 ksi) |
| Te Kaha o te Hua (0.2% te whakahekenga) | ≥414 MPa (60 ksi) |
| Te toronga (i roto i te 2″) | ≥30% |
| Te pakeketanga | ≤287 HB |
| Kiato | 8.44 karamu/cm³ |
| Te Pūwāhi Rewa | 1290 – 1350°C |
Te tikanga o tēnei i roto i te mahi:He kaha te Inconel 625 mō ngā pūnaha paipa pēhanga teitei, ā, he pakari hoki hei tu atu i ngā pānga me te wiri. Ko te roanga iti rawa o te 30% ka taea te piko me te hanga me te kore e pakaru.
Ahakoa ngā pāmahana teitei, ka mau tonu te kaha whai hua o te Inconel 625 tae atu ki te 982°C (1800°F). Ka mau tonu hoki i ngā pāmahana cryogenic — tae atu ki te -196°C — me te kore e pakarukaru, koia te take e kitea ai i roto i ngā pūnaha LNG me te hauota wai.
Ātete ki te Waikura – Te Wāhi Tino Hiranga
Koinei te tino take e utu nui ai te tangata mō te Inconel 625. Ka taea e ia te whakahaere i ngā taiao e whakangaro ana i te maitai kore waikura 316L i roto i ngā marama.
Ngā taiao wai moana me te moana:He ātete te Inconel 625 ki te waikura o te wai moana. Ātete ki te waikura o te waikura, te waikura o ngā kapiti, me te poke koiora. Koia te take e kitea ai i roto i ngā paipa whakamatao wai moana, ngā pūnaha wai ahi, ngā paipa wai taumaha, me ngā taputapu whakaputa wai i raro i te moana.
Te pakaru waikura ahotea hauhā:Koinei te tino patu mō te maitai kore waikura 304 me te 316 i roto i ngā mahi moana me ngā mahi matū. Kāore e pāngia te Inconel 625 e te nikara nā te nui o te nikara i roto.
Ātete waikawa:Ka taea e te Inconel 625 te whakahaere i te waikawa whanariki, te waikawa hauwaiora, te waikawa phosphoric, ngā waikawa whakauru, te chlorine, ngā whakarewa chlorine, ngā fluoride, me ngā kawakore kaha. I roto i te kohu waikawa hauwaiora, ka taea e te tere waikura o te maitai kore waikura 316L te 65 ngā wā teitei ake i te Inconel 625.
Ātete ki te poka:He nui ake te PREN (Pitting Resistance Equivalent Number) o Inconel 625 i te 316L. I roto i te otinga 10% FeCl₃ i te 65°C, ka pakaru kino te 316L i te mea kāore te Inconel 625 e pāngia.
Ratonga kawa (H₂S):Kua whakaaetia te Inconel 625 mō te ratonga kawa e ai ki te NACE MR0175 / ISO 15156. He whānuitia te whakamahinga i roto i te hanga hinu me te hau moana mō ngā wāhanga e pāngia ana e te hauwai whanariki, te hauhā waro, me ngā pūhaumāota.

Tukanga Hanga
Ka hangaia e Womic Steel te paipa Inconel 625 tuimotu mā te tukanga whakahaere:
●Te rewa:Mā te whakarewatanga ā-whakaoho korehau (VIM) me te whakarewatanga anō o te pewa korehau (VAR) ka iti te ihirangi hau me te parakore teitei.
●Te wero:Ka whakamahanahia te paraoa mārō, ka werohia kia hanga he anga tuwhera.
●Te whakaputa wera, te hurihuri rānei:Ka whakaititia te anga tuwhera ki te rahi waenga.
●Te tuhi makariri:Mā te maha o ngā haerenga kume makariri me te whakamahana waenga ka tutuki ai ngā inenga whakamutunga me ngā taunga kikī. Ka whakapai ake te kume makariri i te whakaotinga mata me te tika o ngā inenga.
●Te whakamahana otinga:Mā te whakamahana whakamutunga i te 980-1040°C, ā, muri iho ka whakamatao tere, ka whakahokia mai te ātete ki te waikura me te ngāwari.
●Te whakapūkara me te whakakorekore:Ka tango i te unahi me te waikura, ka waiho he mata ma.
●NDT me te whakamātautau:Whakamātautau wai ātete 100%, whakamātautau ultrasonic, whakamātautau iahiko hurihuri, me te tirotiro i ngā āhuatanga.
Mō ngā paipa whakarewa, ka whakamahia te rīpene hurihuri matao i hangaia, ā, ka whakarewahia mā te whakamahi i te whakarewa TIG, i te whakarewa plasma rānei, ā, muri iho ka whakamahanahia te otinga katoa me te NDT o te hononga whakarewa.
Te Whakarewa me te Hanga
E mōhiotia ana te Inconel 625 mō tōna kaha ki te whakarewa. Ka taea te whakarewa mā te whakamahi i te TIG (GTAW), MIG (GMAW), te whakarewa rakau (SMAW), te whakarewa taiaho, te whakarewa hihi irahiko rānei.
Te konganuku whakakī kua tūtohutia:AWS A5.14 ERNiCrMo-3 (whakakī Inconel 625)
Ngā kōrero matua hei maumahara:
● Kāore e hiahiatia he maimoatanga wera i muri i te whakarewanga — ka whiwhi te koranu i tōna kaha mai i te whakapakari i te wairewa totoka, ehara i te whakapakeketanga o te ua.
● Horoia pai te wāhi whakarewa i mua i te whakarewa — kaua he hinu, he ngako, he waikura rānei.
● Whakahaerehia te wera e tomo mai ana kia kore ai e wera rawa.
● Kia mau te pāmahana i waenganui i te ara ki raro i te 150°C.
● Whakamahia he hau ārai argon parakore, he hau ārai argon-helium rānei.
Mō te whakarewa rerekē (Inconel 625 ki te maitai kore waikura, ki te maitai waro rānei), ko te ERNiCrMo-3 anō hoki te whakakī e taunakitia ana.
