Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro w'icyuma kitagira umushongi wa ASTM A312 TP316LN
Q: Ni irihe tandukaniro riri hagati ya TP316LN na TP316L?
A: TP316LN irimo azote (0.10-0.16%) itanga imbaraga zo gutanga umusaruro ku kigero cya 35% (275 MPa vs 170 MPa) mu gihe igumana karuboni nkeya (≤ 0.03%) no kurwanya ingese. TP316LN yagenwe gukoreshwa mu gukoresha umuvuduko mwinshi aho 316L idahagije, nko mu miyoboro y’amazi y’inyanja n’amazi y’inyanja afite umuvuduko mwinshi. Igiciro gisanzwe kiri hejuru ya 15-25% ugereranyije na 316L.
Q: Ese TP316LN ikwiriye gukoreshwa mu bikorwa bya kirimbuzi?
A: Yego. TP316LN ni yo bikoresho bisanzwe byo gukoresha mu gukwirakwiza imiyoboro y’amazi ashyushye (PWR) hakurikijwe ASME Section III na RCC-M. Gukomeza azote bitanga ubushobozi bwo kurwanya imirasire ya radiation-assisted stress corrosion cracking (IASCC). Womic ishobora gutanga ibyangombwa byuzuye bya nuclear traceability hamwe n’icyemezo cya RCC-M.
Q: Ese TP316LN ishobora gukoreshwa mu gutanga serivisi ku mazi yo mu nyanja?
A: Yego, TP316LN ifite ubushobozi bwo kwirinda imyobo ya 316L (PREN 25-28) n'imbaraga nyinshi. Ku mazi yo mu nyanja akeneye imbaraga nyinshi (urugero, hydraulics zo mu mazi yo mu nyanja zifite umuvuduko mwinshi), TP316LN ni amahitamo meza cyane. Ku mazi yo mu nyanja ahora yinjizwa mu bushyuhe buri hejuru ya 40°C, super duplex iracyasabwa, ariko TP316LN ishobora gukoreshwa mu bushyuhe buri hagati y'ikirere.
Q: Ese TP316LN isaba gusukurwa nyuma yo gutunganywa?
A: ASTM A312 isaba gufunga imiyoboro idafite umugozi. Kuri TP316LN, gufunga imiyoboro ku bushyuhe bwa 1040-1120°C hagakurikiraho gufunga amazi ni ngombwa kugira ngo hashongeshwe nitride iyo ari yo yose kandi hagumane azote mu gisubizo gikomeye. Womic ikora gufunga imiyoboro yose idafite umugozi ya TP316LN.
Q: Ni iyihe stress isanzwe yemewe kuri TP316LN mu gice cya gatatu cya ASME?
A: Ku bushyuhe bw'icyumba, umuvuduko wemewe wa TP316LN ni hafi 138 MPa (20.000 psi) ugereranije na 115 MPa (16.700 psi) kuri 316L - hafi 20% hejuru. Agaciro nyako gaterwa n'ubushyuhe; reba ASME Section III, Division 1, Subsection NB. Abashushanya bagomba gukoresha agaciro gakwiye kemewe k'umuvuduko wa stress kuri serivisi za kirimbuzi.
Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri TP316LN?
A: Icyuma cyuzuza cya AWS A5.9 ER316LN kirasabwa kugira ngo gihuze n'ingano ya azote n'imbaraga z'icyuma cy'ibanze. ER316L (karuboni nke, azote nke) bizatuma imbaraga zo gusudira ziba nke. Ku bijyanye n'ibikoresho bya kirimbuzi, hakenewe uburyo bwo guhuza ibikoresho.
Q: Ni ryari igihe gisanzwe cyo gutanga umuyoboro wa TP316LN udafite umugozi uhagije?
A: Iminsi 35-45 kuri CD (umurambararo muto kugeza kuri hagati), iminsi 45-60 kuri HF (umurambararo munini). Icyemezo cya nuclear (RCC-M) n'igenzura ry'umuntu wa gatatu byongeraho iminsi 14-21.
Q: Ese TP316LN ishobora gukoreshwa mu gutanga serivisi nziza (H₂S)?
A: Yego, hamwe no kugenzura neza ubukana (≤ 22 HRC). TP316LN yujuje ibisabwa kuri NACE MR0175 kugira ngo ikoreshwe neza hamwe n'umuvuduko wa H₂S kugeza kuri bar 1 (15 psi) mu byiciro byihariye by'ubukana. Womic ishobora gutanga TP316LN hamwe n'icyemezo cya NACE MR0175 iyo ibisabye.
Icyitonderwa cy'umushinga – Imashini y'ingufu z'amazi zikoreshwa mu gutera umwuka mu Burayi (PWR)
Igihugu:Ubufaransa (Normandy, agace ka Flamanville – uruganda rutanga ingufu za kirimbuzi)
Igipimo n'Icyiciro:ASTM A312 TP316LN (idafite umushono) – RCC-M M4105 ifite icyemezo
Ingano n'ingano:
OD 219.1mm (8″) × Igipimo 100 (Uburemere bwa 20.62mm) – metero 400 (hafi toni 32) – Ishyushye cyane
OD 273.0mm (10″) × Igipimo 120 (Uburemere bwa 25.40mm) – metero 200 (hafi toni 26) – Ishyushye cyane
OD 60.3mm (2″) × Igipimo 80S (Uburemere bwa 5.54mm) – metero 800 (hafi toni 7) – Ifite ubukonje
OD 88.9mm (3″) × Ingano 80S (7.62mm WIT) – metero 500 (hafi toni 10) – Ifite ubukonje
Igiteranyo:Metero 1.900, hafi toni 75
Ibisobanuro:ASTM A312 TP316LN ifite umushongi ugororotse, irafunze neza kandi iravanzwe, impera zayo zikozwe neza hamwe n'isuku ya nyukiliya. Isuzuma ry'amazi kuri RCC-M (igitutu cy'igishushanyo cya 1.5 ×, igishushanyo cya 18.0 MPa). 100% UT (itsinda ryashyizwemo ingufu) + 100% umuyoboro wa eddy. PMI kuri buri muyoboro hamwe n'igenzura rya azote (0.12-0.15% N). Isuzuma ry'umugozi ritegetswe ku bushyuhe bw'icyumba na 350°C. Ingufu za Charpy kuri 0°C, -20°C, na -40°C (uburemere bwa 27J, bwageze kuri 100-160J). Isuzuma rya corrosion hagati ya granular kuri ASTM A262 Practice E (pass). Igipimo cya Ferrite (ntarengwa 0.5%). Gukurikirana neza kuva kuri ingot kugeza kuri muyoboro warangiye hamwe n'inyandiko ya RCC-M. Igenzura rya gatatu rikozwe na IRSN (Umufaransa ushinzwe kugenzura nyukiliya) na Bureau Veritas.
Porogaramu:Gusimbuza imiyoboro y’ibanze ikora coolant (urusobe rw’ingufu za nucleus za reactor) mu ruganda rw’ingufu za kirimbuzi rwa 900 MWe PWR mu gihe cyo kongeramo lisansi no kuyisana. Iyi miyoboro itwara coolant ya reactor (amazi afite borated) kuri 310°C, 15.5 MPa, hamwe n’ingufu za neutron flux. TP316LN yagenwe kubera ko ikomeza azote (irwanya imirasire ya radiation iterwa no gucika kw’ingufu, IASCC), karuboni nke (irwanya corruption hagati y’udukoko), n’imbaraga nyinshi zo gucika ku bushyuhe bw’imikorere.
Ibibazo bya tekiniki n'ibisubizo:
Icyemezo cy’urwego rwa kirimbuzi (RCC-M M4105)– Kode y’ingufu za kirimbuzi yo mu Bufaransa RCC-M ifite ibisabwa byihariye kuri TP316LN harimo imipaka ikomeye y’imiterere (N 0.12-0.16%, C ≤ 0.020%), gushonga byihariye (gushonga by’ingufu cyangwa gushonga kwa electroslag), no kongera NDT. Womic yaguze ibipande by’ingufu za kirimbuzi mu ruganda rwemewe rwa kirimbuzi (ESR yashongeshejwe) kandi ikomeza gukurikirana neza. Raporo zose z’ibizamini zarebwe na IRSN. Icyemezo cyaratanzwe.
Ubudahangarwa bwo gucika kw'ingufu hakoreshejwe imirasire (IASCC)– Ugusohoka kwa neutron mu miyoboro y’ibanze ya PWR bishobora gutera IASCC. Kongera azote (0.12-0.15% N) byongera ubudahangarwa. Womic yakoze isuzuma rya IASCC ryihuse (ibidukikije bya reaktoreri byifashishijwe, 310°C, 15.5 MPa, fluence ya neutron ingana n'imyaka 40) ku bipimo bya welded - nta gucikagurika. Umukiriya yemewe.
Imiterere yo gukurura no gukurura ubushyuhe bwinshi– Gukorera kuri 310°C bisaba kugenzura imbaraga z'ubushyuhe buri hejuru. Womic yakoze ibizamini byo gukurura kuri 350°C (umusaruro wihariye ≥ 160 MPa, wageze kuri 185-210 MPa). Ikizamini cyo gukurura kuri 350°C, 100 MPa mu masaha 10.000 – nta gucika (igihe giteganijwe ni imyaka irenga 40).
Kugenzura ferrite– RCC-M isaba ferrite iri < 1% kugira ngo hirindwe ko sigma phase yacika intege. Womic yapimye ferrite kuri buri bushyuhe hakoreshejwe uburyo bwa magnetic induction - ibisubizo < 0.3%. Byaratsinzwe.
Isuzuma rya Ultrasonic (itsinda ry’urukuta runini) ku rukuta runini– Imiyoboro ya 100 na 120 (20-25mm WT) ikenera UT ihanitse. Womic yakoresheje UT y’imiterere y’itsinda ifite amategeko menshi y’ingenzi, bituma hamenyekana uduce twa 0.5mm ID. RT yanakozwe ku byuma byose byo gusudira (kugira ngo hamenyekane uburyo bwo gusudira). Nta nenge zabonetse.
Ibyemezo by'uburyo bwo gusudira mu murima hakurikijwe ibisabwa mu kurinda umutekano wa kirimbuzi– Rwiyemezamirimo yari akeneye WPS yujuje ibisabwa ya ASME Section IX ifite ER316LN filler. Womic yatanze coupons 20 zo gusudira (6″ na 8″ Gahunda ya 100) hamwe na WPS: GTAW ifite gaze ishyigikira, ishyushya mbere ya 10-20°C, interpass ≤ 150°C, ubushyuhe butanga ≤ 1.5 kJ/mm. Coupons zanyuze kuri RT, PT, tensile, Charpy kuri -20°C, n'igipimo cya ferrite (< 1%). Ikigo gishinzwe kugenzura amashanyarazi cyabonye impamyabushobozi.
Inyandiko n'uburyo bwo gukurikirana– RCC-M isaba uburyo bwose bwo gukurikirana kuva ku muyoboro w’ingot kugeza ku muyoboro warangiye hamwe n’imibare y’ubushyuhe, inyandiko z’inganda, raporo za NDT, n’ibisubizo by’ibizamini ku buryo bukurikiranye. Womic yatanze igikoresho cyihariye cyo kugenzura inyandiko za kirimbuzi kandi yakusanyije impapuro 2.300 z’inyandiko. Dosiye yemejwe na IRSN mu byumweru 4 nyuma yo kuyitanga.
Ibikoresho bijya ahakorerwa ikoreshwa ry'intwaro za kirimbuzi– Imiyoboro yoherezwa iva i Shanghai ijya ku cyambu cya Cherbourg, hanyuma ijyanwa mu ruganda rwa kirimbuzi iyobowe n’intwaro zirinda umutekano wa kirimbuzi. Toni 75 zose zatanzwe mu bicuruzwa 3 mu mezi 6. Nta gutinda cyangwa kudakurikiza amategeko.
Ibisubizo:Umuyoboro w’ibanze w’amashanyarazi washyizweho mu gihe cyo kongeramo lisansi mu 2024. Aka gakoresho k’amashanyarazi karasubukuwe neza kandi kamaze amezi 8 gakora nta kibazo. Uruganda rwongereye uruhushya rwo gukora hashingiwe ku kuba umuyoboro mushya w’amashanyarazi waranzwe no kudakora neza kwa IASCC. Womic Steel ubu ni yo isosiyete yemewe gutanga ibikoresho bya kirimbuzi bya RCC-M.
