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 burushaho gukomera no gusudira. S31803 ni yo ngano ya mbere ya duplex 2205; S32205 ni verisiyo nziza. Inganda nyinshi ubu zikora ibikoresho byujuje ibisabwa byombi icyarimwe (byemewe n’ibice bibiri). Womic ishobora gutanga S31803/S32205 yemewe n’ibice bibiri iyo ibisabye.
Q: Ese S31803 iracyakwiriye ku mishinga mishya?
A: Yego, S31803 iracyazwi cyane kandi iracyavugwa mu mahame menshi y’inganda. Ariko, ku mishinga mishya, injeniyeri nyinshi zikunda S32205 kubera imiterere yayo ikomeye kandi idashobora gucikamo imiyoboro myinshi. Niba ibisobanuro byawe bisaba S31803, Womic irashobora kuyitanga. Ku miterere mishya, turakugira inama yo gukoresha S32205 cyangwa ibikoresho bifite icyemezo cy’ibice bibiri.
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 S31803 ni ubuhe?
A: S31803 ikwiriye gukoreshwa mu buryo buhoraho kugeza kuri 280°C. Hejuru ya 300°C, gucika intege bishobora kubaho bitewe no gushinga sigma phase. Ku bushyuhe buri munsi ya 300°C, duplex ifite imikorere myiza cyane. Ku bushyuhe buri hejuru, ni byiza gukoresha austenitic grades cyangwa nickel alloys.
Q: Ese S31803 ishobora gukoreshwa muri serivisi ya sour (H₂S)?
A: Yego. Duplex 2205 (zombi S31803 na S32205) yujuje ibisabwa kugira ngo ikoreshwe muri NACE MR0175/ISO 15156 ku gitutu cya H₂S kugeza kuri 0.3 psi (0.02 bar) mu byiciro byihariye by'ubukana. 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 S31803?
A: PREN = Cr% + 3.3 (Mo%) + 16 (N%). Kuri S31803, bitewe n'imiterere nyayo, PREN iri hagati ya 30 na 36. Ibi biri hejuru cyane kurusha 316L (PREN ≈ 24-26), bigaragaza ko hari ubudahangarwa bwiza cyane ku mwobo uri mu bidukikije bya chloride. Kuri S32205, PREN ubusanzwe ni 35-38.
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.
Q: Ni ryari igihe gisanzwe cyo gukoresha umuyoboro wa S31803 duplex welded gikoreshwa?
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 – Imiyoboro y'amazi yo mu Burasirazuba bwo Hagati yo gusukura umunyu (S31803)
Igihugu:Ibihugu by'Abarabu (Abu Dhabi, Ikigobe cy'Abarabu)
Igipimo n'Icyiciro:ASTM A790 S31803 (Duplex 2205)
Ingano n'ingano:
OD 219.1mm (8″) × Gahunda ya 10S (3.76mm WIT) – metero 3.500 (hafi toni 56) – Uburyo bwa EFW
OD 273.0mm (10″) × Gahunda ya 10S (4.19mm WIT) – metero 2.800 (hafi toni 54) – Uburyo bwa EFW
OD 88.9mm (3″) × Gahunda ya 10S (3.05mm WIT) – metero 4.200 (hafi toni 26) – Uburyo bwa ERW
OD 60.3mm (2″) × Gahunda ya 10S (Uburemere bwa 2.77mm) – metero 5.000 (hafi toni 18) – Uburyo bwa ERW
Igiteranyo:Metero 15.500 (15.5 km), hafi toni 154
Ibisobanuro:Ingufu za ASTM A790 S31803 zakuwemo amazi n'ibinyampeke, zikozwe mu mitobe. Isuzuma rya Hydrostatic. 100% UT ku miyoboro ya EFW, umuyoboro wa eddy kuri ERW. PMI kuri buri muyoboro. Igipimo cya ferrite gitegetswe (35-65%, cyagezweho 45-55%). Ingaruka za Charpy kuri -20°C (spec 27J, cyagezweho 80-140J). Isuzuma rya corrosion kuri ASTM G48 Uburyo A (amasaha 24, 22°C) - nta mwobo urimo. Isuzuma rya gatatu ryakozwe na BV (Ibiro Veritas). Icyemezo cya kabiri S31803/S32205 cyatanzwe.
Porogaramu:Imiyoboro yo gusohora amazi y’amazi y’inyanja ifite umuvuduko mwinshi wo gukuramo amazi y’inyanja mu ruganda runini rwo mu mazi y’inyanja (SWRO) ruri i Abu Dhabi. Iyi miyoboro itwara amazi y’amazi y’amazi y’inyanja (umunyu 70.000 ppm, ubushyuhe 35-40°C, pH 7.5-8.0) kuva ku ruhu rwa RO kugeza aho amazi asohokera. Imiyoboro ya 316L yabanje yagize ikibazo cyo kwangirika kw’imiyoboro no gucika kw’imirongo nyuma y’imyaka 4. Duplex 2205 (S31803) yatoranijwe kubera ko yari ifite ubushobozi bwo kurwanya imiyoboro myinshi (PREN 30-36 vs 316L PREN 24-26) kandi ikaba ikomeye cyane.
Ibibazo bya tekiniki n'ibisubizo:
Chloride nyinshi n'amazi y'ubushyuhe bwinshi– Ubushyuhe bw'amazi y'umucanga 40°C n'umunyu 70.000 ppm bitera ahantu hakomeye ho gushyira imyobo. 316L ntabwo ihagije. Womic yatanze S31803 ifite ingano yemejwe (Cr 22.1%, Mo 3.1%, N 0.16%) igera kuri PREN 36. Ikizamini cya G48 cyo gushyira imyobo nta myobo cyagaragaje. Ubushyuhe bw'imyobo bukabije (CPT) bwapimwe kuri 45°C (hejuru y'ubushyuhe bwo gukora). Umukiriya arabyemerewe.
Uburinganire bwa ferrite bwo gusudira– Gusudira EFW hamwe n'ubushyuhe ≤ 1.8 kJ/mm na interpass ≤ 100°C. Ibipimo bya Ferrite: icyuma cyo gusudira 48-54%, HAZ 44-50%, icyuma cy'ibanze 50-55%. Byose biri muri 35-65%.
Igishushanyo mbonera cyoroheje gikoresheje Gahunda ya 10S– Urukuta rworoshye rw’imbaraga ebyiri (Gahunda ya 10S ugereranije na Gahunda ya 40S kuri 316L), rwagabanyije 60% by’uburemere bw’imiyoboro kandi rugabanya ikiguzi cyo gushyigikira inyubako ho miliyoni 1.2 z’amadolari. Womic yatanze igenzura ry’ibipimo kugira ngo imenye neza ko ishyirwa mu bikorwa neza.
Ibikoresho bijyana muri Abu Dhabi– Imiyoboro yoherejwe iva i Shanghai ijya Khalifa Port, Abu Dhabi mu buryo bubiri. Toni 154 zose zatanzwe mu minsi 35. Igenzura ryakozwe na BV ryagaragaje ko nta na kimwe cyakozwe kidakurikije amategeko.
Ibisubizo:Sisitemu yo gusohora amazi y’umunyu yashyizweho mu gihembwe cya kane cya 2023. Nyuma y’amezi 18 ikora, igenzura ryagaragaje ko nta mwobo warimo, ingese cyangwa kwangirika. Uruganda rukora ikoranabuhanga ryashyizeho uburyo bwa duplex 2205 ku miyoboro mishya yose y’amazi y’umunyu. Womic Steel ubu ni yo ihabwa amahirwe menshi yo kwagura uru ruganda.
