A: Yego, nk'uko ASTM A312 ibivuga. Gushyira umuti ku bushyuhe bwa 1040-1120°C hagakurikiraho kuzimya amazi birakenewe kugira ngo hashongeshwe karubide kandi hagerwe ku miterere yagenwe ya mekanike no kudakora neza kwangirika. Iyo hatabayeho gufunga neza kwa gazi, umuyoboro ushobora kuba waragabanutse imbaraga zo gucika no kwangirika hagati y’udusimba. Womic ikora uburyo bwose bwo gufunga ku miyoboro yose ya TP316H.

Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri TP316H?
A: Ku bijyanye no gusudira TP316H, AWS A5.9 ER316H (ihuza karuboni nyinshi) irasabwa kugira ngo ihuze imbaraga zo gukurura. Ariko, ku bijyanye no gusudira mu murima aho ubushyuhe nyuma yo gusudira budashoboka, ER316L ikunze gukoreshwa kugira ngo hirindwe ko HAZ yakwiyongera. Uwashushanyije agomba kugena akurikije ubushyuhe bwa serivisi.

Q: Ni ryari igihe gisanzwe cyo gutanga umuyoboro w'icyuma kitagira umugese wa TP316H?
A: Iminsi 25-35 kuri ERW (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri EFW/LSAW (umurambararo munini). Igihe cyo gukoresha TP316H gisa na 316L.

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.

Porogaramu:Imitwe y'imashini zisohora amazi mu gikoresho cy'amashanyarazi gihujwe (turbine ya gaze + HRSG). Igice cy'imashini zisohora amazi mu gikoresho gitanga umwuka kuri dogere selisiyusi 560, 12.5 MPa. Iyi mashini ihuza imashini zisohora amazi mu gikoresho cy'amashanyarazi n'imashini zisohora amazi mu gitutu kinini. Imashini zisohora amazi mu gikoresho cya 304H zabanje zagize ikibazo cyo kudakora neza no kudakora neza nyuma y'imyaka 10 zikora neza. TP316H yatoranijwe kubera imbaraga zayo nyinshi zo gukurura amazi no kudakora neza mu mwobo (kuva kuri Mo) mu gihe chloride yinjiye mu mazi mabi.

Ibibazo bya tekiniki n'ibisubizo:

Ingufu zo gukurura kuri 560°C na 12.5 MPa– TP316H ifite karuboni 0.06-0.08% n'ingano y'ibinyampeke ASTM 6 yatanze imbaraga zo gucika kw'inyuma kwa 70 MPa kuri 600°C mu masaha 100.000 (byari byateganyijwe). Womic yakoze ikizamini cyo gucika kw'inyuma kwa 1.000h kuri 600°C, 60 MPa – nta gucika kw'inyuma, uburebure bwose bwa 14%. Umukiriya yemeye ibikoresho.

Kugenzura ingano y'ingano y'ibinyampeke kugira ngo habeho kubahiriza amategeko ya ASME Igice cya I– Gukoresha imiyoboro ya Superheater bisaba ko ingano ya ASTM y’ibinyampeke 5-7 kuri ASME (ibinyampeke byiza bitanga ubudahangarwa bwiza bwo gukurura ariko bikagabanya ubudahangarwa bwo gukurura mu gihe cy’ubushyuhe bwinshi cyane). Ingano ya Womic y’ibinyampeke igenzurwa binyuze mu bushyuhe bwo gukurura (1090-1120°C) n’igipimo cyo gukonjesha. Ibisubizo: ASTM 5.5-6.5 ku cyuma cyo hasi, ASTM 6-7 ku cyuma cyometseho. Biremewe.

Guhuza imbaraga zo gukurura icyuma hakoreshejwe ubutare– EFW na ERW welds zigomba kugira imbaraga zo gukurura zingana n'icyuma cyo hasi. Womic yakoresheje ER316H filler kuri EFW kandi yanogeje ERW parameters kugira ngo igere ku mikoranire myiza y’imiyoboro yo gukurura. Ubushyuhe bwinshi bwo gukurura kuri 600°C ku bipimo byo gukurura: bitanga 105-125 MPa, gukurura 230-280 MPa – bigereranywa n'icyuma cyo hasi.

Ubudahangarwa bw'ingufu kuri 560°C– TP316H ikora igipimo cya Cr₂O₃ kirinda kuri 560°C. Umugore yakoze ikizamini cya oxidation (umwuka kuri 600°C mu masaha 500): kongera ibiro 0.12 mg/cm². Byemewe.

Uburyo bwo gusudira mu murima mu gusana superheater– Itsinda ry’abashinzwe kubungabunga uruganda ryari rikeneye WPS yujuje ibisabwa mu gusudira mu murima (umuyoboro uva kuri flange, umuyoboro uva kuri pipe). Womic yatanze ama coupons 25 yo gusudira hamwe na WPS hakoreshejwe GTAW, ER316L filler (kugira ngo hirindwe kongerwamo imbaraga), gushyushya 10-20°C, interpass ≤ 150°C, input y’ubushyuhe ≤ 1.5 kJ/mm. Kuponi zanyuze kuri RT, PT, n’ubushyuhe buri hejuru kuri 600°C. Umukiriya yujuje ibisabwa mu buryo.

Ibikoresho bijyana n'uruganda rw'amashanyarazi rwa Rayong– Imiyoboro yoherejwe iva i Shanghai ijya ku cyambu cya Laem Chabang, hanyuma ijyanwa mu ruganda rw’amashanyarazi. TÜV Tayilande yagenzuye imiyoboro ku cyambu. Toni 84 zose zatanzwe mu bicuruzwa 3 mu byumweru 8. Nta kutubahiriza amabwiriza.

Ibisubizo:Imiyoboro ya Superheater yashyizweho mu gihe cy'ibura rya gatatu rya 2024. Nyuma y'amezi 12 ikora kuri 560°C, 12.5 MPa, igenzura ryakozwe ku murongo ryagaragaje ko nta guhindagurika kw'amazi, nta gupima ogisijeni, kandi nta kwangirika kwabyo byagaragaye. Uru ruganda rwiteze igihe cy'imyaka irenga 20 (ugereranije n'imyaka 10 kuri 304H). Womic Steel ubu ni yo igurisha ryujuje ibisabwa kugira ngo uru ruganda rubone amashanyarazi ashyushye cyane mu gihe kizaza.
