Umuyoboro w'icyuma kitagira umugese wa ASTM A312 TP309 / TP309H: Ubushobozi bwo gukora n'ibisobanuro by'ibicuruzwa

Kuki twafatanya na Womic Steel mu miyoboro ya TP309/309H Welded?

Ingano yuzuye: ERW 1/4″ – 24″, EFW/LSAW 8″ – 60″.

Gufunga byuzuye nyuma yo gusudira (1040-1120°C, kuzimya amazi).

TP309H irahari kugira ngo ikoreshwe mu gushyuha hejuru ya 650°C.

Igihe cyo guhatana: iminsi 25-35 kuri ERW, iminsi 35-50 kuri EFW/LSAW.

Icyemezo cyisi yose: ISO 9001, PED (CE), EN 10204 Ubwoko 3.2.

Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro wa ASTM A312 TP309/309H Usudiwe

Q: Ni irihe tandukaniro riri hagati ya TP309, TP309S, na TP309H?
A: TP309S ifite karuboni nkeya (≤ 0.08%) kugira ngo irusheho gusudira no kurwanya ingese hagati y’uduce duto mu gihe ikoze nk’isudiwe. TP309 (akenshi bivuze kimwe na 309S) ni yo ikoreshwa muri rusange. TP309H ifite karuboni nyinshi (0.04-0.10%) kugira ngo yongere imbaraga zo gukurura ku bushyuhe buri hejuru (hejuru ya 650°C). Kugira ngo ikomeze gukoreshwa mu bushyuhe buri hejuru mu gihe cy’ubushyuhe bwinshi (urugero: imiyoboro irabagirana, ikoreshwa mu gukurura), hitamo TP309H. Kugira ngo ikoreshwe mu buryo bw’ikirere cyangwa aho bidashoboka ko ikoreshwa mu bushyuhe nyuma yo gusudira, hitamo TP309S.

Q: Ni ubuhe bushyuhe ntarengwa bwa serivisi ya TP309?
A: TP309 ikwiriye gukoreshwa mu mwuka kugeza kuri 1000°C (1830°F) kandi irwanya ogisijeni neza. Kugira ngo ikoreshwe mu buryo buhoraho, ishobora kwihanganira kugeza kuri 1035°C. Hejuru ya 1000°C, ubwiyongere bw'ubushyuhe buriyongera; TP310 (25Cr-20Ni) irasabwa gukoreshwa mu gihe cy'ubushyuhe bwa 1100°C.

Q: Ni gute TP309 igereranywa na TP304 ku bijyanye na serivisi y'ubushyuhe bwinshi?
A: TP309 ifite chromium iri hejuru (23% ugereranyije na 18%) na nikeli (13% ugereranyije na 8%), itanga ubudahangarwa bwiza cyane bwo kurwanya okiside (kugeza kuri 1000°C ugereranije na 850°C kuri 304). TP309 kandi ifite ubudahangarwa bwiza bwo kurwanya kaburiseri na sulfide. Kugira ngo serivisi igere kuri 850°C, TP309 niyo nziza.

Q: Ese TP309H ni ngombwa ku miyoboro irabagirana mu itanura ritunganya ubushyuhe?
A: Ku miyoboro irabagirana ikora hejuru ya 650°C mu gihe cy'ubushyuhe (mu bihe by'ubushyuhe), TP309H irasabwa kuko ingano yayo ya karuboni nyinshi itanga imbaraga nyinshi zo gucika kw'ubushyuhe. Ku bijyanye no gukoresha stress nke (urugero, uduseke dushyushya, ibikoresho), TP309S irakwiriye.

Q: Ese TP309 isaba gukururwa n'umuti nyuma yo gusudira?
A: ASTM A312 isaba gufunga imiyoboro ishongeshejwe. Kuri TP309S, gufunga imiyoboro ishongeshejwe nyuma yo gufunga irakenewe kugira ngo ihuze n'imiterere ya mekanike n'ubudahangarwa. Ku gufunga imiyoboro ya TP309S, nta PWHT ikenewe kugira ngo habeho ogisijeni ihagije, ariko kugira ngo habeho ubudahangarwa bwuzuye, gufunga imiyoboro ni ingirakamaro. Womic ikora gufunga imiyoboro yose ishongeshejwe ya TP309.

Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri TP309?
A: Ku bijyanye no gusudira TP309, AWS A5.9 ER309L (cyangwa ER309) niyo isabwa. ER309L (karuboni nkeya) niyo ikwiye gukoreshwa kugira ngo ikomeze kurwanya ingese. Kuri TP309H, ER309 (karuboni isanzwe) ihura neza kurushaho. Kugira ngo TP309 ihuzwe n'ibindi byuma bitagira umugese, ER309L ikunze gukoreshwa nk'igisenge.

Q: Ni ryari igihe gisanzwe cyo gukoresha umuyoboro w'icyuma kitagira umugese wa TP309?
A: Iminsi 25-35 kuri ERW (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri EFW/LSAW (umurambararo munini). TP309H ishobora kugira igihe kirekire cyo kuyobora bitewe n'uburyo bwo gushakisha plaque bwihariye.

Q: Ese TP309 ishobora gukoreshwa mu gutanga serivisi ya aside sulfuri cyangwa hydrochloric?
A: Oya. TP309 ntabwo yagenewe serivisi ya aside; ni aloyi ikoresha ubushyuhe bwinshi. Kugira ngo ikoreshwe muri aside ku bushyuhe bw'icyumba, koresha 304L, 316L, cyangwa duplex. TP309 ni iyo kurwanya ogisijeni ku bushyuhe bwinshi, ntabwo ari iyo kurwanya ingese mu binyabutabire ku bushyuhe buri hasi.

Icyitonderwa cy'umushinga - Imiyoboro igabanya ubushyuhe n'imiyoboro ikonjesha by'imashini zikoresha sima

Igihugu:Vietnam (Intara ya Ha Nam)
Igipimo n'Icyiciro:ASTM A312 TP309H (isudiwe)
Ingano n'ingano:

OD 508mm (20″) × Gahunda ya 40S (15.09mm WIT) – metero 200 (hafi toni 33) – Uburyo bwa EFW

OD 406mm (16″) × Gahunda 40S (12.70mm WIT) – metero 300 (hafi toni 33) – Uburyo bwa EFW

OD 168.3mm (6″) × Gahunda ya 40S (7.11mm WIT) – metero 500 (hafi toni 13) – Uburyo bwa ERW
Igiteranyo:Metero 1.000, hafi toni 79

Ibisobanuro:Ingano za ASTM A312 TP309H zakuwemo amazi n'ibinyampeke, zikozwe mu mazi. Isuzuma rya Hydrostatic. 100% UT ku miyoboro ya EFW, umuyoboro wa eddy kuri ERW. PMI kuri buri muyoboro. Isuzuma rya ngombwa ryo gukurura ubushyuhe buri hejuru kuri 800°C (nibura 100 MPa, ryagezweho 135-160 MPa). Isuzuma rya corrosion intergranular kuri ASTM A262 Practice E (pass). Isuzuma rya gatatu ryakozwe na TÜV Vietnam.

Porogaramu:Gusimbuza imiyoboro ishyushya no gushyiramo imiyoboro ikonjesha mu ruganda rwa sima (ikorwa rya clinker). Umuyoboro ushyushya utwara imyuka ishyushye yo mu itanura (850-950°C) irimo ivumbi (uduce duto twa clinker dukoreshwa muri sima) n'imyuka itwika (CO₂, SOx, NOx). Imiyoboro ishyushya ni imwe mu bigize sisitemu yo gukonjesha ya clinker, ikora clinker ishyushye kuri 500-800°C hamwe n'imiterere yo gukurura. Imiyoboro ya 304H yabanje yarananiwe nyuma y'imyaka 3 kubera kwangirika kwa oxidation, carburizing, no guhinduka kw'imiyoboro.

Ibibazo bya tekiniki n'ibisubizo:

Gushyira ogisijeni no gushyiramo kaburiseri kuri 850-950°C– TP304H (18% Cr) ipima vuba cyane hejuru ya 850°C. TP309H ifite 23% Cr ikora igipimo cya Cr₂O₃ gihamye kurushaho, irwanya ogisijeni na kaburizeti. Umugore yakoze ikizamini cya ogisijeni (umwuka kuri 950°C mu gihe cy'amasaha 500): kwiyongera ibiro 0.8 mg/cm² (ugereranije na 304H isanzwe ya 4.5 mg/cm²). Umukiriya arabyemerewe.

Imbaraga zo kwiruka ku bushyuhe bwinshi– Umuyoboro w’amazi uri hejuru y’amazi ufite uburemere bwihariye kandi ubushyuhe bwinshi bushobora kwaguka. TP309H ifite karuboni 0.07-0.09% yatanze imbaraga nyinshi zo gukurura. Ubushyuhe bwinshi bwo gukurura kuri 800°C: umusaruro wa 145 MPa, gukurura 210 MPa. Isuzuma rya Creep (1.000h kuri 800°C, 40 MPa) – nta gucika.

Ubudahangarwa ku munaniro uterwa n'ubushyuhe– Ifuru ya sima irahagarara/itangira gutera ubwihindurize bw'ubushyuhe. TP309H ifite imiterere mito yateweho umuti (utubuto duto twa ASTM 6-7) yatanze ubushobozi bwo kurwanya umunaniro w'ubushyuhe. Nta gucikagurika kwagaragaye nyuma y'inshuro 500 z'ubushyuhe mu isuzuma rya laboratwari.

Ubudahangarwa bw'umukungugu wa sima– Umuyoboro uzamuka uhura n'umukungugu wa sima urimo kwangirika. Ubukana bwa TP309H 85 HRB butanga ubudahangarwa buri ku rugero rwo hasi. Ku gushwanyagurika gukomeye, haracyakoreshwa umwambaro udashobora kwangirika; TP309H ikora nk'inkunga y'imiterere.

Uburyo bwo gusudira mu gusana imirima– Gahunda yo guhindura imikorere y’uruganda rwa sima yari ifite igihe gito cyo gusudira. Womic yatanze WPS ikoresheje ER309L filler, GTAW + SMAW, ifite interpass ≤ 150°C. Coupon 15 zo gusudira zanyuze kuri RT, PT, hamwe n’ubushyuhe buri hejuru.

Ibikoresho bijya i Ha Nam– Imiyoboro yoherejwe iva i Shanghai ijya ku cyambu cya Haiphong, hanyuma ikamyo igera aho yari iherereye mu birometero 100. Toni 79 zose zatanzwe mu bicuruzwa 2 mu byumweru 6. Igenzura rya TÜV ryakozwe nta na kimwe cyakozweho.

Ibisubizo:Umuyoboro mushya wa TP309H wo kuzamuka n'imiyoboro ikonjesha byashyizweho mu gihe cyo guhindura imikorere mu 2023. Nyuma y'amezi 18, igenzura ryagaragaje ko ogisijeni ari ntoya cyane (ubugari bwa skeli < 0.1mm) kandi nta guhindagurika cyangwa kwangirika kw'amazi byacitse. Umukiriya avuga ko igihe cyo gukora ari imyaka 8-10 (ugereranije n'imyaka 3 kuri 304H). Womic Steel ubu ni yo isabwa cyane mu gutanga ibikoresho by'ubushyuhe bwinshi by'uru ruganda rwa sima.
