Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro w'icyuma kitagira umushongi wa ASTM A312 TP316H
Q: Ni irihe tandukaniro riri hagati ya TP316H na TP316L?
A: TP316H ifite karuboni nyinshi (0.04-0.10% ugereranije na ≤ 0.03% kuri 316L), ibyo bikaba bitanga imbaraga nyinshi cyane zo gucika kw'izuba ku bushyuhe buri hejuru ya 550°C. 316L irwanya cyane ingese hagati y'udusimba nyuma yo gusudira. Ku bikoresho bifite ubushyuhe bwinshi (hejuru ya 550°C) n'imitsi, koresha TP316H. Ku bikoresho bisudiye bidakoresha ubushyuhe nyuma yo gusudira ku bushyuhe buri hasi, 316L ni yo ikwiriye. TP316H kandi irimo molybdenum imwe (2-3%) yo kurwanya imyobo.
Q: Ni ryari nkwiye guhitamo TP316H kuruta TP304H?
A: Niba ahantu hashyuha cyane harimo chloride (urugero: umwuka urimo chloride ntoya, icyuma gikonjesha, icyuma gikozwe mu ibumba gifite umunyu wa chloride), hitamo TP316H kubera ubushobozi bwayo bwo kurwanya molybdenum. Niba chloride zitahari, TP304H irahendutse cyane. Zombi zifite imbaraga zisa ku bushyuhe bugera kuri 650°C.
Q: Ni ubuhe bushyuhe ntarengwa bwa serivisi ya TP316H?
A: TP316H ifite agaciro kemewe k’umuvuduko muri ASME Igice cya II, Igice cya D kugeza kuri 815°C (1500°F). Ariko, ku bushyuhe bw’igihe kirekire, ikoreshwa kugeza kuri 700°C. Hejuru ya 700°C, ingano ifite chromium (309, 310) cyangwa aloyi za nikeli zishobora gukenerwa kugira ngo habeho ubudahangarwa bw’amazi. Mu bidukikije birimo chloride, ubushyuhe ntarengwa bushobora kugabanywa no kudahangarwa kw’imyobo aho kuba ukugenda.
Q: Ese TP316H ishobora gukoreshwa mu gihe yasuwede?
A: Ku bijyanye n'ikoreshwa ry'umuvuduko, ASTM A312 isaba gusudira umuti nyuma yo gukora imiyoboro (atari nyuma yo gusudira umurima). Ku gusudira umurima wa TP316H, ubushyuhe nyuma yo gusudira (gusudira umuti) muri rusange ntabwo ari ingirakamaro, bityo abakora ibikoresho benshi bakoresha icyuma cya 316L cyuzuza icyuma kugira ngo birinde kwangirika kwa HAZ. Ariko, kugira ngo serivisi ikoreshwe mu bushyuhe bwinshi aho gukurura ari ngombwa, gusudira 316H bishobora kuba ngombwa. Womic itanga imiyoboro ya TP316H mu buryo bwo gusudira umuti; gusudira umurima bigomba gukoresha icyuma gikwiye n'ubushyuhe buke.
Q: Ese TP316H isaba kugenzura ingano y'ibinyampeke kugira ngo serivisi yo gukurura igere?
A: Ku birebana na serivisi y'ubushyuhe bwinshi aho gukurura ari ikintu cyo kwitabwaho mu buryo bw'igishushanyo mbonera, Igice cya I na VIII bya ASME bisaba kugenzura ingano y'ingano. TP316H ubusanzwe ifite ingano y'ingano ya ASTM 5-7. Womic ishobora gutanga raporo zo gupima ingano y'ingano iyo ibisabye.
Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri TP316H?
A: AWS A5.9 ER316H (ihuza karubone nyinshi) cyangwa ER316L (ikarubone nkeya) irashobora gukoreshwa. Kugira ngo habeho guhuza imbaraga zo gukurura mu isudira, ER316H irasabwa. Ariko, ku gusudira mu murima aho ubushyuhe nyuma yo gusudira budashoboka, ER316L ikunze gukoreshwa kugira ngo hirindwe ko ibintu byangirika. Uwashushanyije agomba kugena akurikije ubushyuhe bwa serivisi n'ibisabwa ku muvuduko.
Q: Ni ryari igihe gisanzwe cyo gutanga umuyoboro wa TP316H udafite umugozi?
A: Iminsi 25-35 kuri CD (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri HF (umurambararo munini). Igihe cyo gukoresha TP316H gisa na 316L. Isuzuma ry’umuntu wa gatatu ryongeraho iminsi 7-14. Isuzuma ry’ibizamini riyongeraho iminsi 14-21.
Icyitonderwa cy'umushinga - Gusimbuza Superheater y'Uruganda rw'amashanyarazi rwa Combined Cycle mu Burasirazuba bwo Hagati (UAE)
Igihugu:Ibihugu by'Abarabu (Abu Dhabi – Inkombe z'Inyanja ya Arabiya)
Igipimo n'Icyiciro:ASTM A312 TP316H (idafite umushono) – hamwe n'ibizamini by'inyongera byo kurwanya gucika no kwangirika kw'imiyoboro
Ingano n'ingano:
OD 60.3mm (2″) × Igipimo 80S (Uburemere bwa 5.54mm) – metero 2.000 (hafi toni 14) – Ifite ubukonje
OD 88.9mm (3″) × Igipimo 80S (Ubwinshi bwa 7.62mm) – metero 1.500 (hafi toni 18) – Ifite ubukonje
OD 114.3mm (4″) × Igipimo 80S (Uburemere 8.56mm) – metero 800 (hafi toni 14) – Ifite ubukonje
OD 168.3mm (6″) × Gahunda 80S (10.97mm WIT) – metero 400 (hafi toni 12) – Ishyushye cyane
Igiteranyo:Metero 4.700, hafi toni 58
Ibisobanuro:ASTM A312 TP316H ifite umushongi ugororotse, urimo amazi n'ibinyampeke, impande zirimo imirasire. Isuzuma rya Hydrostatic. Umuyoboro wa Eddy (CD) na UT (HF). PMI kuri buri muyoboro hamwe no kugenzura Mo (2.2-2.6% Mo). Igipimo cy'ingano y'ibinyampeke gitegetswe (ASTM 5-7, cyagezweho 5.5-6.5). Ingufu za Charpy kuri -20°C (spec 27J, cyagezweho 80-140J). Isuzuma ry'ubushyuhe bwo hejuru kuri 600°C (spec: umusaruro ≥ 100 MPa, wagezweho 120-150 MPa; igenzura ≥ 200 MPa, cyagezweho 260-310 MPa). Isuzuma rya Creep rupture kuri 600°C, 50 MPa kuri 1,000h - nta gucika. Isuzuma rya Pitting Corruption kuri ASTM G48 Uburyo A (6% FeCl₃, amasaha 24 kuri 22°C) - nta gucika. Ikizamini cyo kwangirika hagati y’udusimba duto dukurikije ASTM A262 Practice E (gutsinda - nta bushobozi bwo kubikora). Igenzura rya gatatu ryakozwe na TÜV UAE.
Porogaramu:Gusimbuza imiyoboro n'imitwe y'amashanyarazi mu ruganda rw'amashanyarazi ruhuza (turbine ya gaze + HRSG) ruherereye ku nkombe z'inyanja ya Arabiya. Iyi superheater itanga umwuka kuri 580°C, 12.5 MPa. Uru ruganda rukoresha amazi yo mu nyanja gukonjesha kuri condenser, naho amazi yo mu mazi ya HRSG arimo chloride nto (2-5 ppm Cl⁻ ituruka ku gutakaza amazi akonje). Imiyoboro ya TP304H superheater yabanje yagize ikibazo cyo kwangirika nyuma y'imyaka 8 ikora bitewe n'imiyoboro yatewe na chloride mu gace gashyuha cyane. TP316H yatoranijwe kubera ingano yayo ya molybdenum (2-3%) itanga ubushobozi bwo kurwanya imiyoboro, hamwe na karubone nyinshi (0.06-0.08%) kugira ngo ikomere kuri 580°C.
Ibibazo bya tekiniki n'ibisubizo:
Gushonga kw'ibice kuri 580°C bivuye kuri chloride nto– TP304H (0% Mo) yashyizwe mu mwobo iyo chloride (2-5 ppm) yinjijwe mu mwobo. TP316H hamwe na Mo 2.3-2.5% yatanze PREN 25-26. Womic yakoze ikizamini cya G48 cyo gupima kuri 22°C, 40°C, na 50°C (bigaragaza imiterere y’aho yashyizwe). Nta mwobo kuri 22°C na 40°C; nta mwobo ushyirwamo gato kuri 50°C nyuma y’amasaha 72 (byemewe kuko ubushyuhe bwa serivisi ari 580°C ariko nta mazi y’amazi, ahubwo ni ayo yashyizwemo gusa). Umukiriya arabyemerewe.
Ingufu zo gucika ku bushyuhe bwa 580°C– TP316H ifite karuboni 0.06-0.08% n'ingano y'ibinyampeke ASTM 6 yatanze imbaraga zo gucika kw'inyuma kwa 55 MPa kuri 600°C mu masaha 100.000 (byari byateganyijwe). Womic yakoze ikizamini cyo gucika kw'inyuma kwa 1.000h kuri 600°C, 50 MPa – nta gucika kw'inyuma, uburebure bwose bwa 11%. Umukiriya arabyemerewe.
Kugenzura ingano y'ingano y'ibinyampeke kugira ngo habeho kubahiriza amategeko ya ASME Igice cya I– Imiyoboro ya Superheater isaba ingano ya ASTM y'ibinyampeke 5-7. Ingano ya Womic y'ibinyampeke igenzurwa binyuze mu bushyuhe bwo gukurura amazi (1070-1100°C) n'igipimo cyo gukonjesha. Ibisubizo: ASTM 5.5-6.5 ku cyuma cy'ibanze, ASTM 6-7 ku isudira (kugira ngo hamenyekane aho bihurira). Biremewe.
Impamyabushobozi yo gusudira mu murima– Itsinda rishinzwe kubungabunga uruganda ryari rikeneye WPS yujuje ibisabwa kugira ngo ihindurwe imiyoboro. Womic yatanze ama coupons 25 yo gusudira (2″ na 4″ Schedule 80S) hamwe na WPS hakoreshejwe GTAW hamwe na ER316L filler (kugira ngo hirindwe ubushyuhe), gushyushya 10-20°C, interpass ≤ 150°C, ubushyuhe bugera kuri 1.5 kJ/mm. Kuponi zatsinze RT, PT, tensile, Charpy kuri -20°C, na G48 pitting test kuri 40°C. Umukiriya yemeje uburyo bwo gukora.
Ubudahangarwa bw'ingufu kuri 580°C hamwe na chloride nto– TP316H ikora igipimo cya Cr₂O₃ kirinda, ariko chloride zishobora kwangiza igipimo. Womic yakoze ikizamini cya oxidation cy’izunguruka (500 cycles, 580°C → ambient, hamwe na 50 ppm Cl⁻ spray buri nshuro 10). Kongera ibiro 0.15 mg/cm² - byemewe.
Ibikoresho bijyana uruganda rw'amashanyarazi rwa Abu Dhabi– Imiyoboro yoherejwe iva i Shanghai ijya Abu Dhabi, hanyuma ijyanwa mu ruganda. TÜV yagenzuye imiyoboro ku cyambu. Toni 58 zose zatanzwe mu bicuruzwa 2 mu byumweru 8. Nta kutubahiriza amategeko.
Ibisubizo:Imiyoboro mishya ya TP316H superheater yashyizweho mu gihe cy'ibura rya 2 C 2024. Nyuma y'amezi 10 ikora, igenzura ryakozwe hakoreshejwe borescope ryagaragaje ko nta mwobo warimo, nta guhindagurika kw'amazi, kandi nta gupima ogisijeni. Uruganda rwiteze igihe cy'imyaka irenga 20 (ugereranije n'imyaka 8 kuri 304H). Uruganda rwashyizeho uburyo bwa TP316H ku bice byose bya superheater n'ibishya mu nganda zabo z'amashanyarazi zo ku nkombe aho hari trace chloride.
