Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro w'icyuma kitagira umushongi wa ASTM A312 TP347/347H
Q: Ni irihe tandukaniro riri hagati ya TP347 na TP321 kuri serivisi ikoresha ubushyuhe bwinshi?
A: TP347 ikoresha niobium (columbium) stabilization mu gihe TP321 ikoresha titanium. TP347 ifite imbaraga zo gukurura neza mu bushyuhe buri hejuru (hejuru ya 550°C) kandi ni yo ikoreshwa mu miyoboro y'amashanyarazi ihindura imiterere y'amashanyarazi. TP321 ikunze gukoreshwa cyane mu gukoresha stress nke. Ku bushyuhe buri hejuru ya 650°C, TP347H ni yo ikundwa.
Q: TP347H ni iki kandi ni ryari igomba gukoreshwa?
A: TP347H ifite ingano ya karuboni nyinshi (0.04-0.10% ugereranije na ≤ 0.08% kuri TP347) kandi igenewe by'umwihariko serivisi y'ubushyuhe buri hejuru aho imbaraga zo gukurura ari ingenzi. Koresha TP347H ku bice by'inkuta binini, imiyoboro ya superheater, n'imiyoboro ya radiant heater ikora hejuru ya 550°C.
Q: Ese gufunga imiyoboro ya TP347 birakenewe?
A: Yego, ASTM A312 isaba gufunga imiyoboro ya TP347. Ubushyuhe bushongesha karubide za niobium zakozwe mu gihe cyo gutunganya kandi bugatuma niobium iboneka kugira ngo ihuzwe na karuboni mu gihe cyo kuyitunganya. Womic ikora gufunga imiyoboro yose ya TP347 idakora neza.
Q: Ese TP347 ishobora gusudira idakoresheje ubushyuhe nyuma yo gusudira?
A: Yego. TP347 yagenewe gukoreshwa mu buryo bwa "as-sudded" nta bushyuhe butangwa nyuma yo gushyushya. Uburyo bwo gushimangira niobium butuma ikoranabuhanga ritabasha gukurura ubushyuhe mu gace kagizweho ingaruka n'ubushyuhe (HAZ). Ibi bituma TP347 ikundwa cyane mu gutunganya no gutunganya ibikoresho byo mu murima.
Q: Ni ubuhe bushyuhe ntarengwa bwa serivisi ya TP347?
A: TP347 ifite ubushobozi bwo kurwanya ogisijeni kugeza kuri 900°C mu kirere (serivisi ihoraho). Ku bijyanye no gukora buri gihe, ubushyuhe bwa 870°C ni bwo busanzwe. Ku bijyanye n'umuvuduko, agaciro kemewe k'umuvuduko kuri ASME B31.3 kagera kuri 815°C (1500°F). Ku bushyuhe buri hejuru ya 650°C hamwe n'umuvuduko mwinshi, TP347H irasabwa.
Q: Igihe gisanzwe cyo gutanga umuyoboro wa TP347 udafite umugozi ni ikihe?
A: Iminsi 25-35 kuri CD (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri HF (umurambararo munini). Isuzuma rya IGC ryongeraho iminsi 7-10. Isuzuma ry’umuntu wa gatatu ryongeraho iminsi 7-14. TP347H ishobora kugira igihe kirekire cyo kuyobora bitewe n’uburyo bwihariye bwo kubona ibikoresho.
Q: Ni izihe nyandiko zitangwa?
A: MTC (EN 10204 3.1 cyangwa 3.2), raporo y'ibizamini bya hydrotest, raporo z'ubushyuhe bwa eddy/UT, raporo ya PMI (hamwe n'igenzura rya Nb), raporo y'ibizamini bya IGC, raporo zo gupfunyika/gushyiramo umuriro, raporo y'ibipimo, urutonde rw'ibipakiye, COO.
Icyitonderwa cy'umushinga - Midwestern USA Catalytic Reformer Heater Tube yo gusimbuza
Igihugu:Leta Zunze Ubumwe za Amerika (Indiana, uruganda rutunganya inzoga rwo mu Burengerazuba bwo hagati)
Igipimo n'Icyiciro:ASTM A312 TP347H (idafite umushono) – hamwe n'ibizamini by'inyongera byo gucikamo ibice
Ingano n'ingano:
OD 88.9mm (3″) × Igipimo 80 (Ubwinshi bwa 8.89mm) – metero 800 (hafi toni 12) – Ifite ubukonje
OD 114.3mm (4″) × Igipimo 80 (11.13mm WIT) – metero 500 (hafi toni 11) – Ifite ubukonje
OD 168.3mm (6″) × Igipimo 80 (15.09mm WIT) – metero 200 (hafi toni 11) – Ishyushye cyane
Igiteranyo:Metero 1.500, hafi toni 34
Ibisobanuro:ASTM A312 TP347H ifite umushongi ugororotse, urimo amazi n'ibinyampeke, impera zikozwemo. Isuzuma rya Hydrostatic. Umuyoboro wa Eddy (CD) na UT (HF). PMI kuri buri muyoboro hamwe n'igenzura rya Nb (byagezweho kuri 0.6-0.8% Nb). Isuzuma rya corrosion ritegetswe hagati y'ibinyampeke kuri ASTM A262 Practice E (nta gitero cyagabweho). Isuzuma rya tensile rikabije kuri 650°C (ibipimo: umusaruro ≥ 110 MPa, wagezweho kuri 140-170 MPa). Isuzuma rya creep rupture kuri 650°C, 50 MPa, 1,000h - nta rupture. Ingano y'ibinyampeke ASTM 6-7. Igenzura rya gatatu ryakozwe na TÜV USA.
Porogaramu:Gusimbuza imiyoboro y'ubushyuhe ihindura imiterere y'amashanyarazi (Platforming unit). Iyi mashini ikora kuri 650-700°C ifite ikirere gikungahaye kuri hydrogen (70% H₂, 20% hidrokaboni, 10% indi myuka). Umuvuduko w'imikorere ni 3.5 MPa. Imiyoboro ya TP321 yabanje yananiwe nyuma y'imyaka 12 bitewe no guhinduka kw'imirasire y'amashanyarazi no kwangirika kw'imirasire y'amashanyarazi. TP347H yatoranijwe kubera imbaraga zayo zo kwangirika no kudahinduka kw'imirasire y'amashanyarazi.
Ibibazo bya tekiniki n'ibisubizo:
Ingufu zo gucika ku bushyuhe buri hagati ya 650-700°C– TP347H ifite karuboni 0.06-0.08% n'ingano y'ibinyampeke ASTM 6 yatanze imbaraga zo gucika kw'inyuma > 50 MPa kuri 650°C. Womic yakoze ikizamini cyo gucika kuri 650°C, 50 MPa, 1,000h – nta gucika kw'inyuma. Ubushyuhe bwo hejuru kuri 650°C: umusaruro ni 145-165 MPa. Umukiriya arabyemerewe.
Ubudahangarwa bwa karuburize mu kirere cya hydrogen– Gukomeza Niobium birinda imvura ya karuboni ku nkengero z'ibinyampeke. Ikizamini cya "carburizing" cyakozwe n'abagore (cyakoreshejwe 5% CH₄/95% H₂ kuri 650°C mu gihe cy'amasaha 500): kwiyongera ibiro 0.15 mg/cm², ubujyakuzimu bwa karuboni < 0.1mm. Umukiriya yemewe.
Ubudahangarwa bw'ingese hagati y'udusate– Ikizamini cya ASTM A262 Practice E (amasaha 120 muri aside sulfate-sulfuriki y'umuringa) nta ngaruka zagaragaye hagati y'udukoko. Byaratsinzwe.
Impamyabushobozi yo gusudira mu murima– Itsinda rishinzwe kubungabunga ububiko bw’ibikoresho bya refinery ryari rikeneye WPS yujuje ibisabwa kugira ngo ihindurwe imiyoboro. Womic yatanze ama coupons yo gusudira hamwe na WPS ikoresheje GTAW hamwe na ER347 filler, ishyushya 10-20°C, interpass ≤ 150°C, ubushyuhe bugera kuri 1.5 kJ/mm. Kuponi zanyuze kuri RT, PT, n'ubushyuhe buri hejuru.
Ibikoresho bijyanwa mu ruganda rutunganya ibicuruzwa muri Indiana– Imiyoboro yoherejwe iva i Shanghai ijya i Chicago, hanyuma ijyanwa mu ruganda rutunganya ibiribwa. Toni 34 zose zatanzwe mu gihe cy'ibyumweru 4. TÜV yagenzuwe aho binjirira. Inyandiko zakiriwe nta kibazo.
Ibisubizo:Imashini ivugurura ibikoresho bya Catalytic yongeye gutangira gukora neza nyuma yo kuvugurura. Nyuma y'amezi 18 ikora, igenzura ryagaragaje ko nta guhindagurika kw'ibikoresho, nta gushyushya ibikoresho bya carburizing, ndetse nta n'icyuho cyagaragaye. Umukiriya yiteze ko izakomeza gukora imyaka irenga 20. Womic Steel ubu ni yo ihabwa agaciro n'abayitunganya kubera ubushyuhe bwinshi.
