Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro w'icyuma gitemba ukozwe mu cyuma cya ASTM A312 TP347/TP347H
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. TP347 kandi ifite ubushobozi bwo kurwanya corruption iterwa na aside polythionic stress. Ku bushyuhe buri hejuru ya 650°C, TP347H ni yo ikundwa cyane.
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. Ifite agaciro k'umuvuduko mwinshi wemewe muri ASME Igice cya I na VIII ku bushyuhe buri hejuru ya 550°C. Koresha TP347H ku bice by'inkuta binini, imiyoboro ya superheater, na radiant coils za heater.
Q: Ese gufunga umuti bisaba umuyoboro wa TP347 uhujwe?
A: Yego, ASTM A312 isaba gufunga imiyoboro ya TP347. Ubushyuhe bushongesha karubide za niobium zakozwe mu gihe cyo gusudira kandi bugatuma niobium iboneka kugira ngo ihuzwe na karuboni mu gihe cyo kuyikoresha. Ubushyuhe busanzwe bwo gufunga imiyoboro: 1050-1100°C, hagakurikiraho gukonjesha vuba (kuzimya amazi). Womic ikora gufunga imiyoboro yose ya TP347.
Q: Ese TP347 ishobora gusudira idakoresheje ubushyuhe nyuma yo gusudira?
A: Yego. TP347 yagenewe gukoreshwa mu buryo bwa "assudded" hatabayeho kuvugururwa nyuma yo kuvugururwa. Gukomeza niobium bibuza kumva ubushyuhe mu gace kagizweho ingaruka n'ubushyuhe (HAZ). Ku gusudira mu murima, nta PWHT ikenewe, bigatuma TP347 irushaho kuba nziza mu gutunganya no gukora 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) kuri TP347. Ku bushyuhe buri hejuru ya 650°C hamwe n'umuvuduko mwinshi, TP347H irasabwa.
Q: Ese mutanga isuzuma ry’ingufu hagati y’udukoko?
A: Yego. Dukora ASTM A262 Practice E (acide sulfate-sulfuric y'umuringa) kugira ngo tumenye neza ko idakora neza. Ibi ni ngombwa ku nganda nyinshi zitunganya ibinyabutabire n'izikoresha peteroli. Ikizamini kiraboneka ku muntu wa gatatu.
Q: Ni ryari igihe gisanzwe cyo gukoresha umuyoboro w'icyuma kitagira umugese wa TP347?
A: Iminsi 25-35 kuri ERW (ubugari buto kugeza ku buringanire), iminsi 35-50 kuri EFW/LSAW (ubugari bunini). TP347H ishobora gusaba igihe kirekire cyo kuyobora bitewe n'uko hari plaque yihariye iboneka. Isuzuma rya corruption hagati y'udusimba ritanga ingano ...
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 (isudiwe)
Ingano n'ingano:
OD 88.9mm (3″) × Gahunda 80S (7.62mm WIT) – metero 800 (hafi toni 18) – Uburyo bwa ERW
OD 114.3mm (4″) × Gahunda 80S (8.56mm WIT) – metero 500 (hafi toni 16) – Uburyo bwa ERW
OD 168.3mm (6″) × Gahunda 80S (10.97mm WIT) – metero 200 (hafi toni 13) – Uburyo bwa EFW
Igiteranyo:Metero 1.500, hafi toni 47
Ibisobanuro:Ingano za ASTM A312 TP347H 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. Isuzuma rya corruption ritegetswe hagati y'uduce duto kuri ASTM A262 Practice E (nta gitero cyagabweho). Isuzuma rya creep rupture kuri 650°C (nibura amasaha 1000, nta cyacitse). Isuzuma rya radiyo (100%) ku miyoboro ya EFW. Isuzuma rya gatatu ryakozwe na TÜV USA.
Porogaramu:Gusimbuza imiyoboro y'ubushyuhe ya catalytic reformer (Platforming unit) mu ruganda rwo mu Burengerazuba bwa Midwest. Iyi mashini ikora kuri 650-700°C ifite ikirere gikungahaye kuri hydrogen (70% H₂, 20% hidrokaboni, 10% indi myuka). Umuvuduko wo gukora ni 3.5 MPa. Imiyoboro yabanje (TP321) yananiwe gukora nyuma y'imyaka 12 bitewe no guhinduka kw'imiyoboro y'ubushyuhe n'ingufu. TP347H yatoranijwe kubera imbaraga zayo zo gukurura no kudashyiramo umwuka.
Ibibazo bya tekiniki n'ibisubizo:
Ingufu zo gucika ku bushyuhe buri hagati ya 650-700°C– TP347H ifite ingano ya karuboni 0.06-0.08% n'ingano y'ibinyampeke ASTM 5-6 yatanze imbaraga zo gucika kw'inyama. Womic yakoze ikizamini cyo gucika kw'inyama ku bushyuhe buri hejuru kuri 650°C: yatanze 110 MPa, 270 MPa yo gucika kw'inyama. Ikizamini cyo gucika kw'inyama (amasaha 1.000 kuri 650°C, 60 MPa) nta gucika kw'inyama cyagaragaje. Umukiriya yemeye ibikoresho.
Ubudahangarwa bwa karuburize mu kirere cya hydrogen– Ahantu hashyushye cyane hashobora gutera ubwiyongere bw'ibinure mu mubiri, bigagabanya ubushobozi bwo guhagarara neza. Gutuza niobium muri TP347H birinda imvura ya karuboni ku nkengero z'ibinyampeke. Umugore yakoze ikizamini cya karuboni (guhura na 5% CH₄/95% H₂ kuri 650°C mu gihe cy'amasaha 500). Kongera ibiro byari 0.2 mg/cm², munsi cyane y'umukiriya wa 0.5 mg/cm².
Gutunganya ubushyuhe no kugenzura ubushyuhe– Gusudira TP347H bisaba umwuka ugana inyuma (argon) kugira ngo hirindwe ogisijeni y'imbere. Womic yatanze imiyoboro ifunze neza ifite imiyoboro isukuye kandi twatanze uburyo bwo gusudira: inzira y'imizi ya GTAW ifite argon inyuma, hagakurikiraho SMAW fill (ER347 filler). Twatanze coupons 30 zo gusudira kugira ngo tumenye uko bikorwa. Coupons zose zatsinze isuzuma rya radiyo na PT.
Igenzura rya PMI kuri TP347H ugereranije na TP347– Umukiriya yasabye PMI 100% kugira ngo yemeze ingano ya karuboni (TP347H ifite 0.04-0.10% C ugereranije na TP347 ≤ 0.08%). Womic yakoze XRF hamwe na analyzer ya karuboni kuri buri muyoboro. Imiyoboro yose yanyuze ku rugero rwa karuboni 0.06-0.08%.
Umuyoboro munini wa santimetero 6 ugororotse kugira ngo uhuze neza– Imiyoboro ya EFW ya santimetero 6 yasabaga kugororoka kwa mm 1.5 kuri metero 3 kugira ngo flange ihuzwe. Womic yakoresheje imashini igorora ifite imigozi 4. Kugororoka kwa nyuma kwageze kuri mm 0.8-1.2 kuri metero 3.
Ibikoresho bijya mu ruganda rukora isuku (ingengabihe y'ivugurura)– Hateganijwe gusimbuza icyuma gishyushya mu gihe cy’ibyumweru 4. Womic yazanye toni 47 zose mu buryo bumwe iminsi 10 mbere yuko icyuma gitangira gushyushya. Gutanga toni ku gihe byatumye ishyirwaho ry’ibikoresho by’amashanyarazi rihita ritangira.
Ibisubizo:Iyi mashini ihindura ibikoresho by’amashanyarazi yasubiwemo neza nyuma yo kuyihindura. Nyuma y’amezi 24 ikora, igenzura ryagaragaje ko nta guhindagurika kw’amashanyarazi kwagaragaye, nta gushyushya ibikoresho by’amashanyarazi byakoreshejwe, kandi nta gucikagurika kw’ibikoresho byayo. Iyi mashini imaze gukoresha TP347H mu gusimbuza imiyoboro yose ihindura ibikoresho by’amashanyarazi mu nganda zayo. Womic Steel ubu ni yo ikoreshwa cyane mu gukwirakwiza imiyoboro itagira amashanyarazi mu bushyuhe bwinshi.
