Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro wa ASTM A790 S32760 Super Duplex Welded
Q: Ni irihe tandukaniro riri hagati ya S32760 na S32750?
A: S32760 irimo tungsten (0.5-1.0%) n'umuringa (0.5-1.0%) hiyongereyeho chromium, molybdenum, na azote. S32750 ntabwo ifite W cyangwa Cu yagenwe. Tungsten yongera ubushobozi bwo kudafata imyanda (yongera kuri PREN) naho umuringa wongera ubushobozi bwo kudafata imyanda (sulfure, fosiforuke). S32760 ikunze gukundwa kubera serivisi za aside shimi. Zombi zifite imiterere imwe ya mekanike n'ubushobozi bwo kudafata imyanda (PREN ≥ 40).
Q: Ese S32760 ingana na Zeron 100?
A: Yego. Zeron 100 ni izina ry'ubucuruzi rya S32760 super duplex stainless steel. Imiterere ya shimi n'imiterere yayo birasa. Womic itanga S32760 yujuje ibisabwa na Zeron 100.
Q: Ni ubushyuhe ntarengwa bwa serivisi ya S32760 ni ubuhe?
A: Kimwe na S32750, S32760 ikwiriye gukoreshwa mu mazi yo mu nyanja kugeza kuri 80°C. Ku bidukikije bidafite chloride, ishobora gukoreshwa kugeza kuri 280°C. Hejuru ya 280°C, habaho gucika intege bitewe no kurema sigma phase. Ku bipimo by'ubushyuhe bwinshi (> 300°C), ni byiza gukoresha alloys zishingiye kuri nikeli.
Q: Kuki gufunga umuti ari itegeko ku muyoboro wa S32760 uhujwe?
A: Super duplex ifite W na Cu irushaho kwibasirwa n’imvura hagati y’ibice by’icyuma (sigma, chi, R-phase) muri HAZ iyo ubukonje butinze. Gushyira umuti ku bushyuhe bwa 1070-1120°C bishongesha ibice byose hagati y’ibice by’icyuma kandi bigasubiza ingano ya ferrite/austenite. Womic ikora uburyo bwose bwo gutera umuti ku miyoboro yose ya S32760 ivanze.
Q: Ese S32760 ishobora gukoreshwa muri serivisi ya sour (H₂S)?
A: Yego. S32760 yujuje ibisabwa kugira ngo ikoreshwe muri serivisi ya sour hakurikijwe NACE MR0175/ISO 15156 ku gitutu cya H₂S kugeza kuri 1.0 bar (15 psi). Inyongera za umuringa na tungsten ntizigira ingaruka mbi ku mikorere ya sour. Ubukomere bugenzurwa kuri ≤ 28 HRC.
Q: Ni iki gipimo cy’ubudahangarwa bw’imiyoboro y’amazi (PREN) cya S32760?
A: PREN = Cr% + 3.3 (Mo%) + 16 (N%) + 1.5 (W%). Kuri S32760 ifite imiterere y’amazina 25% Cr, 3.7% Mo, 0.27% N, 0.7% W, PREN ≈ 25 + 12.2 + 4.3 + 1.05 = 42.5. PREN ntoya kuri ASTM ni 40. Ibi bigereranywa na S32750 ariko hamwe n’umusaruro wiyongereyeho W.
Q: Ese mutanga icyemezo cya NORSOK M-650?
A: Yego. Womic Steel yujuje ibisabwa kuri NORSOK M-650 ku miyoboro ya super duplex stainless steel welded (yombi S32750 na S32760). Inyandiko yuzuye irahari.
Q: Igihe gisanzwe cyo gukoresha umuyoboro wa S32760 uhujwe ni ikihe?
A: Iminsi 40-55 kuri ERW (umurambararo muto kugeza kuri hagati), iminsi 55-75 kuri EFW/LSAW (umurambararo munini). Inyandiko za NORSOK M-650 zongeraho iminsi 15-20. Igenzura ry’umuntu wa gatatu ryongeraho iminsi 7-14.
Icyitonderwa cy'umushinga – Sisitemu y'amazi yo mu nyanja y'Amajyaruguru yo gukoresha umuriro n'amazi akonje (S32760)
Igihugu:Noruveje (Inyanja ya Ruguru, agace k'umurima wa Oseberg)
Igipimo n'Icyiciro:ASTM A790 S32760 (Super Duplex) – NORSOK M-650 yujuje ibisabwa
Ingano n'ingano:
OD 219.1mm (8″) × Gahunda ya 40S (Uburemere bwa 8.18mm) – metero 800 (hafi toni 27) – Uburyo bwa EFW
OD 323.9mm (12″) × Gahunda ya 40S (10.31mm WIT) – metero 500 (hafi toni 36) – Uburyo bwa EFW
OD 88.9mm (3″) × Gahunda 80S (7.62mm WIT) – metero 1.200 (hafi toni 17) – Uburyo bwa ERW
OD 60.3mm (2″) × Gahunda 80S (5.54mm WIT) – metero 2.500 (hafi toni 19) – Uburyo bwa ERW
Igiteranyo:Metero 5.000, hafi toni 99
Ibisobanuro:Ingano za ASTM A790 S32760 zakuwemo amazi n'ibinyampeke, zikozwe mu mazi. Isuzuma rya Hydrostatic. PAUT 100% ku miyoboro ya EFW, umuyoboro wa eddy + UT kuri ERW. PMI kuri buri muyoboro. Igipimo cya ferrite gitegetswe (35-65%, cyagezweho 45-55%). Ingaruka za Charpy kuri -46°C (spec 27J, cyagezweho 80-160J). Isuzuma rya corrosion rikurikije ASTM G48 Uburyo A kuri 40°C - nta mwobo urimo. Inyandiko za NORSOK M-650 zirimo mikorobe (nta sigma/chi), inzira z'ubukana, na ferrite mapping. Igenzura rya gatatu ryakozwe na DNV Noruveje. NACE MR0175 kugira ngo serivisi irusheho kuba nziza.
Porogaramu:Gusimbuza imiyoboro y'amazi yo mu nyanja n'amazi akonje ku gice cy'inyanja y'Amajyaruguru ishaje (Oseberg field). Ubushyuhe bw'amazi yo mu nyanja: 10-15°C, ariko rimwe na rimwe ibintu bidahinduka hamwe na chlorine (yo gukurura ibintu bikomoka kuri biofouling) bitera imiterere y'ubukana bw'aho hantu. Imiyoboro ya 22Cr duplex (S32205) yari imaze imyaka 18 ikora ariko yagaragaje ko hari aho yacitse mu bice by'amaguru adakora neza. Umukoresha yahisemo S32760 kugira ngo ikomeze guhangana n'imiyoboro kandi ikomeze igihe kirekire (hafi imyaka 25+).
Ibibazo bya tekiniki n'ibisubizo:
Gutemba mu mazi y'inyanja adatemba hamwe n'amazi ya chlorine– Ibice by'amazi y'umuriro bifite amaguru adakora neza bihura n'amazi yo mu nyanja adakora neza hamwe n'ibisigazwa bya chlorine, bishobora kugabanya ubushyuhe bw'imyobo ikomeye. S32760 hamwe na CPT > 80°C itanga ingano. Womic yakoze G48 Method A kuri 40°C (amasaha 72) – nta myobo irimo. Yanakoze ikizamini cya cyclic polarization – nta hysteresis igaragaza ko nta myobo ishobora gutera.
Inyandiko za NORSOK M-650– Urwego rwa Noruveje rukeneye icyemezo cya NORSOK M-650. Womic yatanze inyandiko zuzuye: gupima ferrite (weld 48-54%, HAZ 45-51%, BM 47-55%), uburyo bwo gukomereka (nta max 275 HV10), microstructure (nta sigma, chi, R-phase), n'ibisubizo by'ibizamini bya corrosion. DNV yemeje.
Uburyo bwo gusudira mu gusana platifomu– Itsinda rishinzwe kubungabunga platifomu ryari rikeneye WPS yujuje ibisabwa mu gusudira mu murima. Womic yatanze ama-coupons 25 yo gusudira (ingano ya 3″, 8″) hamwe na WPS hakoreshejwe ER2594 filler, input y'ubushyuhe ≤ 1.3 kJ/mm, interpass ≤ 100°C, gaz backing ya azote. Ama-coupons yanyuze kuri RT, PT, Charpy kuri -46°C (weld 85-120J), n'igipimo cya ferrite (weld 45-55%).
Igishushanyo mbonera cyoroheje– Inkuta zoroshye za S32760 (Gahunda ya 40S) ugereranije n'icyuma cya karuboni cya S32760 cya mbere (amafaranga yo kwangirika). Byagabanyije uburemere bw'imiyoboro ku kigero cya 55%, bigabanya toni 120 z'ikiguzi cyo guhindura inyubako.
Ibikoresho bijya ku rubuga rw'ibicuruzwa mu mahanga– Imiyoboro yoherejwe iva i Shanghai ijya i Bergen, hanyuma ijya Oseberg ikoresheje ubwato butanga ibicuruzwa. Dosiye ya NORSOK M-650 (amapaji 620) yatanzwe mu buryo bw'ikoranabuhanga. Toni 99 zose zahageze ku gihe.
Ibisubizo:Sisitemu y'amazi yo kuzimya umuriro n'amazi akonje yashyizweho mu gihembwe cya kabiri cya 2024. Nyuma y'amezi 12 ikora, igenzura ryakozwe hakoreshejwe ROV no kugenzura imbere ku ma coupon ryagaragaje ko nta mwobo cyangwa imiterere y'icyuho cyangiritse. Ikigo gishinzwe kuyicunga cyazamuye ibipimo byayo ku bikoresho byose by'amazi yo mu nyanja y'Amajyaruguru kuri S32760 kugira ngo bishyirwemo ibintu bishya n'ibindi by'ingenzi. Womic Steel ubu iri ku rutonde rw'abatanga serivisi bemerewe n'ikigo gishinzwe kuyicunga kugira ngo ikoreshwe mu miyoboro minini ya duplex munsi ya NORSOK M-650.
