Umuyoboro w'icyuma kitagira umushongi wa ASTM A312 TP321/321H

Kuki wafatanya na Womic Steel mu gukora umuyoboro udafite umugozi wa TP321/321H?

Ingano yuzuye: Ifite ishusho ikonje 1/2″ – 8″, Ishyushye irangizwa 4″ – 24″.

Gutera umuti wose (1050-1120°C, amazi yo kuzimya) - ni ingenzi cyane mu gutuma titanium ikomeza gukora neza.

Isuzuma rya corrosion hagati y’udusimba duto dukurikije ASTM A262 Practice E rirahari (ni ngombwa kuri TP321).

TP321H yo kugira imbaraga zo gukurura ubushyuhe bwinshi.

Igihe cyo gutanga serivisi: iminsi 25-35 kuri CD, iminsi 35-50 kuri HF.

Ibibazo Bikunze Kubazwa:

Q: Ni iyihe nyungu ya TP321 kurusha TP304 yo gutanga serivisi ikoresha ubushyuhe bwinshi?
A: TP321 irimo titaniyumu yo gutuza karubone, ikarinda imvura ya chromium carbide mu gihe cyo gusudira no guhura n’ubushyuhe bwinshi (425-870°C). Kugira ngo ubushyuhe bukomeze hejuru ya 550°C hamwe n’ubushyuhe, TP321 irasabwa. TP304L ikoresha karubone nkeya (0.03% ntarengwa) ariko ishobora gukomeza kwiyongera uko igihe kigenda gihita ku bushyuhe buri hejuru ya 550°C.

Q: TP321H ni iki kandi ni ryari igomba gukoreshwa?
A: TP321H ifite karuboni nyinshi (0.04-0.10% ugereranije na ≤ 0.08% kuri TP321) kugira ngo wongere imbaraga zo gukurura ku bushyuhe buri hejuru ya 650°C. Koresha TP321H ku miyoboro ya superheater, imiyoboro ya radiant heater, n'izindi porogaramu zikoresha stress nyinshi kandi zikoresha ubushyuhe bwinshi.

Q: Ese TP321 isaba gusukurwa nyuma yo gutunganywa?
A: Yego, ASTM A312 isaba gukurura umuti. Uburyo bwo kuvura ubushyuhe bushongesha karubide za titaniyumu kandi bugatuma titaniyumu iboneka kugira ngo ihuzwe na karuboni mu gihe cyo kuyikoresha. Womic ikora gukurura umuti wose ku miyoboro yose ya TP321 idafunze.

Q: Ese TP321 ishobora gukoreshwa muri serivisi yoroshye (H₂S)?
A: TP321 ntabwo ikunze kugaragazwa ku birebana na serivisi ya sour (NACE MR0175). Kuri H₂S ifite ubushyuhe bwinshi, tekereza kuri 316L cyangwa duplex. TP321 ahanini ni urwego rw'ubushyuhe bwinshi.

Q: Ni ubuhe bushyuhe ntarengwa bwa serivisi ya TP321?
A: TP321 ifite ubushobozi bwo kurwanya ogisijeni kugeza kuri 900°C buri gihe, 870°C igakomeza. Ku bushyuhe bwinshi, TP310 irasabwa.

Q: Ni ryari igihe gisanzwe cyo gutanga umuyoboro wa TP321 udafite umugozi urimo umugozi?
A: Iminsi 25-35 kuri CD, iminsi 35-50 kuri HF. Isuzuma rya IGC ryongeraho iminsi 7-10. Isuzuma ry’umuntu wa gatatu ryongeraho iminsi 7-14.

Icyitonderwa cy'umushinga - Gusimbuza umuyoboro w'amashanyarazi wa Gulf Coast Refinery Coker

Igihugu:Leta Zunze Ubumwe za Amerika (Texas, uruganda rutunganya ibikomoka ku bimera rwo muri Gulf Coast)
Igipimo n'Icyiciro:ASTM A312 TP321H (idafite umushono) – hamwe n'ibizamini by'inyongera byo gucikamo ibice
Ingano n'ingano:

OD 88.9mm (3″) × Igipimo 80 (Ubwinshi bwa 8.89mm) – metero 1.200 (hafi toni 18) – Ifite ubukonje

OD 114.3mm (4″) × Igipimo 80 (11.13mm WIT) – metero 800 (hafi toni 18) – Ifite ubukonje

OD 168.3mm (6″) × Igipimo 80 (15.09mm WIT) – metero 400 (hafi toni 22) – Ishyushye cyane
Igiteranyo:Metero 2.400, hafi toni 58

Ibisobanuro:ASTM A312 TP321H ifite umushongi ugororotse, ifunze neza kandi ivanze neza, impera zayo zikozwe mu mazi. Isuzuma rya Hydrostatic. Umuriro wa Eddy (CD) na UT (HF). PMI kuri buri muyoboro. Isuzuma rya corrosion ritegetswe hagati y’uduce duto kuri ASTM A262 Practice E (nta gitero). Isuzuma rya tensile rikabije kuri 650°C (ibipimo: umusaruro ≥ 100 MPa, wageze kuri 130-160 MPa). Isuzuma rya creep rupture kuri 650°C, 40 MPa, 1,000h - nta rupture. Ingano y'ingano ya ASTM 6-7. Igenzura rya gatatu ryakozwe na TÜV USA.

Porogaramu:Gusimbuza imiyoboro ya radiant ya coker furnace yatinze. Imiyoboro ikora kuri 650-700°C hamwe n'umwuka wa hydrocarbon, ikorwa rya coke, no gushyuha. Imiyoboro ya 304H yabanje yananiwe nyuma y'imyaka 8 bitewe no guhinduka kw'imiyoboro no kwangirika kw'imitsi. TP321H yatoranijwe kubera ko yatumaga titanium ikomeza gukora neza no gukomera kwayo kwinshi.

Ibibazo bya tekiniki n'ibisubizo:

Ingufu zo gucika ku bushyuhe buri hagati ya 650-700°C– TP321H ifite karuboni 0.06-0.08% n'ibinyampeke byiza (ASTM 6) byatanze imbaraga zo gukurura > 40 MPa kuri 650°C. Isuzuma rya Creep (1,000h, 650°C, 40 MPa) nta gukurura kwagaragaye. Umukiriya yemeye.

Ubudahangarwa bwa carburisation– Gukomeza kwa titanium birinda imvura ya chromium carbide, bigatuma chromium iboneka kugira ngo habeho okiside. Womic yakoze ikizamini cya carburisation (5% CH₄/H₂ kuri 650°C mu gihe cy'amasaha 500): kwiyongera ibiro 0.3 mg/cm², byemewe.

Ikizamini cyo kwangirika hagati y'udusate– Imyitozo ya ASTM A262 E yatsinzwe (nta gitero kiri hagati y’udusate), byemeza ko titanium ihamye neza.

Ibikoresho bijyanwa mu ruganda rutunganya ibikomoka ku mavuta muri Texas– Imiyoboro yoherejwe iva i Shanghai ijya i Houston, hanyuma ijyanwa mu ruganda rutunganya ibiribwa. Toni 58 zose zatanzwe mu gihe cy'ibyumweru 6. Igenzura rya TÜV ryaratsinzwe.

Ibisubizo:Igishyushya cya Coker cyongeye gutangira neza. Nyuma y'amezi 12, igenzura ryagaragaje ko nta guhindagurika kw'imodoka kwagaragaye. Umukiriya yiteze ko azamara imyaka irenga 15.
