A: S32205 ifite imipaka ikomeye y’imiterere (Cr 22-23% vs 21-23%, N 0.14-0.20% vs 0.08-0.20%) kandi ifite azote ntoya cyane, ibyo bigatuma ubushobozi bwo guhangana n’imyobo no gusudira burushaho kwiyongera. S32205 yasimbuye cyane S31803 mu buryo bugezweho (ASTM A790 ubu irimo byombi, ariko S32205 niyo ikunzwe cyane).
Q: Kuki gufunga umuti ari itegeko ku muyoboro wa duplex welded?
A: Gusudira bibangamira imiterere ya ferrite/austenite iringaniye kandi bishobora guteza ingaruka mbi hagati y’ibyuma (sigma, chi) mu gace kagizweho ingaruka n’ubushyuhe. Gusudira umuti kuri 1040-1120°C hagakurikiraho gufunga amazi bigarura ubuziranenge bwa ferrite bwa 35-65% kandi bigashonga hagati y’ibyuma. Iyo hatabayeho gusudira umuti, kurwanya ingese no gukomera birangirika cyane. Womic ikora gusudira umuti ku miyoboro yose yasutsweho uduce duplex.
Q: Ni ubushyuhe ntarengwa bwa serivisi ya S32205 ni ubuhe?
A: S32205 ikwiriye gukoreshwa mu buryo buhoraho kugeza kuri 280°C mu bidukikije bya chloride. Hejuru ya 300°C, gucika intege bishobora kubaho bitewe no kurema sigma phase (ndetse no mu bikoresho bifunze uko igihe kigenda gihita). Ku bushyuhe buri munsi ya 300°C, duplex igira imikorere myiza cyane.
Q: Ese S32205 ishobora gukoreshwa muri serivisi ya sour (H₂S)?
A: Yego. Duplex 2205 yujuje ibisabwa kugira ngo ikoreshwe muri NACE MR0175/ISO 15156 ku gitutu cya H₂S kugeza kuri 0.3 psi (0.02 bar) mu ntera yihariye y'ubukana. Ku bijyanye na H₂S iri hejuru, super duplex (S32750) irasabwa. Womic itanga duplex ifite ubukana bwa ≤ 28 HRC kuri buri gisabwa cya NACE.
Q: Ni iki gipimo cy’ubudahangarwa bw’imiyoboro y’amazi (PREN) cya S32205?
A: PREN = Cr% + 3.3 (Mo%) + 16 (N%) = 22 + 3.3 × 3.2 + 16 × 0.17 ≈ 35-38. Ibi biri hejuru cyane kurusha 316L (PREN ≈ 24-26), bigaragaza ko birwanya cyane imyobo mu bidukikije bya chloride. S32205 ikwiriye gukoreshwa mu mazi yo mu nyanja ku bushyuhe bugera kuri 30-40°C.
Q: Ese mutanga icyemezo cya NORSOK M-650?
A: Yego. Womic Steel yujuje ibisabwa kuri NORSOK M-650 ku miyoboro ibiri ya sinteti ishongeshejwe mu byuma bitagira umugese. Dutanga inyandiko zuzuye zirimo gupima ferrite, uburyo bwo gukomereka, gupima ingese, no gusuzuma imiterere y’ibice. Ibi bikunze kuba ngombwa ku mishinga yo mu nyanja iri ku mugabane wa Noruveje.
Q: Igihe gisanzwe cyo gukoresha umuyoboro wa duplex welded ni ikihe?
A: Iminsi 30-40 kuri ERW (ubugari buto kugeza ku buringanire), iminsi 40-60 kuri EFW/LSAW (ubugari bunini). Inyandiko za NORSOK M-650 zongeraho iminsi 10-15. Igenzura ry’umuntu wa gatatu ryongeraho iminsi 7-14.
Icyitonderwa cy'umushinga - Ivugurura rya sisitemu yo gukonjesha amazi yo mu nyanja yo mu majyaruguru
Igihugu:Noruveje (Inyanja ya Ruguru, Ikibuga cy'Abarobyi)
Igipimo n'Icyiciro:ASTM A790 S32205 (Duplex 2205) – NORSOK M-650 yujuje ibisabwa
Ingano n'ingano:
OD 219.1mm (8″) × Gahunda ya 10S (3.76mm WIT) – metero 2.200 (hafi toni 35) – Uburyo bwa EFW
OD 323.9mm (12″) × Gahunda ya 10S (Uburemere bwa 4.57mm) – metero 1.500 (hafi toni 39) – Uburyo bwa EFW
OD 60.3mm (2″) × Gahunda ya 10S (Uburemere bwa 2.77mm) – metero 4.000 (hafi toni 14) – Uburyo bwa ERW
Igiteranyo:Metero 7.700 (7.7 km), hafi toni 88
Ibisobanuro:Ingufu za ASTM A790 S32205 zakuwemo amazi n'ibinyampeke, zikozwe mu mazi. Isuzuma rya Hydrostatic. 100% UT ku miyoboro ya EFW, umuyoboro wa eddy kuri ERW. PMI kuri buri muyoboro. Igipimo cya ferrite gitegetswe (intego ya 40-60%, yagezweho kuri 45-55%). Ingaruka za Charpy kuri -46°C (spec 27J, yagezweho kuri 80-140J). Isuzuma rya corrosion kuri ASTM G48 Uburyo A (amasaha 24, 22°C) - nta mwobo urimo. Pake y'inyandiko ya NORSOK M-650 irimo uburyo bwo gukomereka n'isuzuma rya microstructure. Igenzura rya gatatu ryakozwe na DNV Noruveje.
Porogaramu:Ivugurura rya sisitemu yo gukonjesha amazi yo mu nyanja ku gice cyo ku Nyanja y'Amajyaruguru (Troll field). Sisitemu ipompa amazi yo mu nyanja yayunguruwe (4-12°C, 3.5% by'umunyu, pH 8.1) kugira ngo ikonjeshe compressors za gaze n'amashanyarazi ya hydraulic. Imiyoboro ya 316L yabanje yagize ikibazo cyo kwangirika no gucika nyuma y'imyaka 8 ikoreshwa. Duplex 2205 yatoranijwe kubera ko ifite ubushobozi bwo kurwanya cyane imyobo (PREN 35-38 vs 316L PREN 24-26) n'imbaraga nyinshi (ituma inkuta zoroshye kandi zigabanye uburemere ku gice cyo ku rukuta).
Ibibazo bya tekiniki n'ibisubizo:
Ubudahangarwa bw'ingufu mu mazi y'inyanja y'Amajyaruguru no mu miyoboro yayo– Ubushyuhe bw'amazi yo mu nyanja buri hagati ya 4-12°C, ariko imiterere idahindagurika mu maguru yapfuye ishobora gutera ingese. Womic yatanze S32205 hamwe na PREN yemejwe ≥ 36. Uburyo bwa G48 Ikizamini cyo gupima imyobo (amasaha 24, 22°C) nta mwobo cyagaragaje. Ikizamini cy'ubushyuhe bw'imyobo (CPT) kuri ASTM G48 Uburyo bwa C (1M NaCl, 1V) bwageze kuri CPT ≥ 50°C (hejuru cyane y'ubushyuhe bwa serivisi). Umukiriya yaremeye.
Uburinganire bwa ferrite bwo gusudira no kugenzura intera hagati y'ibyuma– Gusudira EFW byasabaga kugenzura cyane uburyo ubushyuhe bwinjira (≤ 1.8 kJ/mm) n'ubushyuhe bwo hagati ≤ 100°C kugira ngo hirindwe sigma phase. Womic yapimye ferrite ku bice bya weld (imyanya 10 kuri buri weld). Ibisubizo: weld metal ferrite 48-55%, HAZ 45-52%, base metal 48-58% – byose biri mu gipimo cya 35-65%. Isuzuma rya microstructure nta bice bya sigma cyangwa chi ryagaragaje.
Inyandiko za NORSOK M-650– Urwego rwa Noruveje rukeneye icyemezo cya NORSOK M-650 ku bikoresho bibiri. Womic yatanze inyandiko zuzuye: imbonerahamwe zo gupima ferrite, uburyo bwo gukomereka (icyuma cyo gusukamo 280 HV10, HAZ max 275 HV10, icyuma cyo hasi max 270 HV10), ibisubizo by'ibizamini bya corrosion, n'inyandiko z'ibizamini byo gusukamo ibyuma. Umushakashatsi wa DNV yemeje inyandiko zose.
Impanuka ya Charpy kuri -46°C– Ubushyuhe bw’imbeho mu Nyanja y’Amajyaruguru n’ubukonje bwa Joule-Thomson bushobora guterwa no kugabanya umuvuduko wa gaze byasabaga ubushyuhe buri hasi. Womic yakoze isuzuma rya Charpy V-Notch kuri -46°C ku byuma byo gusudira, HAZ, n’icyuma cyo hasi. Ibisubizo: icyuma cyo hasi 120-160J, gusudira 80-120J, HAZ 90-130J – byose biri hejuru cyane y’ibisabwa kuri 27J.
Igishushanyo mbonera cyoroheje bitewe n'imbaraga nyinshi– Duplex 2205 ifite imbaraga zo gutanga umusaruro wa 450 MPa ugereranije na 316L kuri 170 MPa. Abashushanya platifomu bakoresheje Schedule 10S aho gukoresha Schedule 40S ku miyoboro y'amazi yo mu nyanja, bagabanya uburemere bw'imiyoboro ho 60% kandi bazigama toni 50 z'inkunga y'inyubako. Womic yatanze imiyoboro ifite ingano zihamye kugira ngo ifatanye neza.
Ibikoresho bijya ku rukuta rw'inyanja ya Ruguru– Imiyoboro yoherejwe iva i Shanghai ijya i Bergen, muri Noruveje ikoresheje ubwato bunini, hanyuma ijyanwa ku rubuga ikoresheje ubwato butanga ibikoresho. DNV yabonye uburyo bwo gupakira no kubika. Toni 88 zose zatanzwe nta cyangiritse.
Ibisubizo:Sisitemu yo gukonjesha amazi yo mu nyanja yashyizweho mu gihembwe cya kabiri cya 2024. Nyuma y'amezi 12 ikora, igenzura ryakozwe kuri interineti (ILI) n'isuzuma rya coupon byagaragaje ko nta mwobo warimo, ingese, cyangwa kwangirika. Iyi serivisi yahisemo duplex 2205 yo kuvugurura sisitemu y'amazi yo mu nyanja mu gihe kizaza mu micungire yayo yo mu Nyanja y'Amajyaruguru. Womic Steel ubu ni yo isosiyete yemewe kugurisha imiyoboro ya duplex y'iyi serivisi muri NORSOK M-650.
