Q: Ese TP317L ishobora gukoreshwa mu gutanga serivisi ku mazi yo mu nyanja?
A: Ifite ubushobozi buke. TP317L ifite ubushobozi bwo kwirinda imyobo kurusha 316L mu mazi yo mu nyanja, ariko kugira ngo amazi yo mu nyanja akomeze kwinjizwa mu kirere ku bushyuhe bw'ikirere, ni byiza gukoresha super duplex (2205) cyangwa alloys nyinshi. TP317L ishobora kwemerwa mu gace ka splash cyangwa mu gukoranaho igihe runaka. Ku bijyanye n'uburyo bwo gukonjesha amazi yo mu nyanja aho 316L yananiwe, tekereza kuri duplex 2205 cyangwa 316L ifite uburinzi bwa cathodic.
Q: Ese TP317L ikwiriye serivisi ya chlorine dioxide (ClO₂) mu nganda zikora bleach?
A: Yego. TP317L ni yo ikoreshwa mu gukwirakwiza imiyoboro ya ClO₂ mu bimera bya bleach n'impapuro. Irwanya ibidukikije bya ClO₂ bitanga ogisijeni nyinshi kandi bifite chloride nyinshi. 316L ntiyemerwa; gucika intege kw'imiyoboro ni ibintu bisanzwe. TP317L imaze imyaka ibarirwa muri za mirongo ikoreshwa neza.
Q: Ese TP317L isaba gukururwa n'umuti nyuma yo gusudira?
A: ASTM A312 isaba gufunga imiyoboro ivanze. Kuri TP317L, gufunga imiyoboro ku bushyuhe bwa 1040-1120°C hagakurikiraho gufunga amazi ni ngombwa kugira ngo ishongeshe karubide za molybdenum kandi igarure ubudahangarwa bwa ruswa. Womic ikora gufunga imiyoboro yose ivanze ya TP317L. Ku gusudira mu murima (gusana), TP317L ishobora gukoreshwa mu buryo bwo gusudira nta PWHT mu bikorwa byinshi bitari ngombwa, ariko ubudahangarwa bwa ruswa bwose bushobora kugabanuka.
Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri TP317L?
A: Icyuma cyuzuza cya AWS A5.9 ER317L kirasabwa, kuko gihuye n'ingano ya 3.0-4.0% ya Mo y'icyuma cy'ibanze. ER316L (2-3% Mo) ishobora gukoreshwa muri bimwe mu bikorwa ariko bigatuma habaho ubudahangarwa buke mu gusuka. Kugira ngo ubudahangarwa buke bwa ER317L burusheho gukomera, koresha ER317L.
Q: Ni ryari igihe gisanzwe cyo gutanga umuyoboro w'icyuma kitagira umugese wa TP317L?
A: Iminsi 25-35 kuri ERW (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri EFW/LSAW (umurambararo munini). Igihe cyo gukoresha TP317L gisa na 316L kuko ari urwego rusanzwe mu nganda nyinshi, nubwo ruto kurusha 316L.
Q: Ese TP317L ishobora gukoreshwa mu gutanga aside asetiki?
A: Yego. TP317L ifite ubushobozi bwo kurwanya aside acetic ishyushye, harimo n'ubwinshi bwayo kugeza kuri 100% ku bushyuhe buringaniye (kugeza kuri 150°C). Ku bushyuhe buri hejuru cyangwa aside acetic nziza cyane, hashobora gukenerwa alloys nyinshi (urugero, duplex, titanium). TP317L ikoreshwa cyane mu nganda zikora aside acetic.
Icyitonderwa cy'umushinga – Pulp Mill Bleach Plant Chlorine Dioxide Piping Replacement (Kanada)
Igihugu:Kanada (British Columbia, uruganda rw'imbere mu nganda)
Igipimo n'Icyiciro:ASTM A312 TP317L (isutswe) – hamwe n'ibizamini by'inyongera byo kurwanya imiyoboro
Ingano n'ingano:
OD 88.9mm (3″) × Gahunda ya 10S (3.05mm WIT) – metero 800 (hafi toni 6) – Uburyo bwa ERW
OD 114.3mm (4″) × Gahunda ya 10S (3.05mm WIT) – metero 600 (hafi toni 7) – Uburyo bwa ERW
OD 168.3mm (6″) × Gahunda ya 10S (3.40mm WIT) – metero 400 (hafi toni 5) – Uburyo bwa ERW
OD 219.1mm (8″) × Gahunda ya 10S (3.76mm WIT) – metero 200 (hafi toni 4) – Uburyo bwa EFW
Igiteranyo:Metero 2.000, hafi toni 22
Ibisobanuro:Ingano za ASTM A312 TP317L 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 hamwe n'igenzura ry'ibikubiye muri Mo (nibura 3.0%, byagezweho 3.2-3.6%). Isuzuma rya corruption ritegetswe hagati y'uduce duto kuri ASTM A262 Imyitozo E (inyura). Isuzuma rya corruption kuri ASTM G48 Uburyo A (amasaha 24 kuri 22°C muri 6% FeCl₃) – nta mwobo urimo. Impanuka ya Charpy kuri -20°C (nibura 27J, byagezweho 80-130J). Igenzura rya gatatu ryakozwe na SGS Canada.
Porogaramu:Gusimbuza imiyoboro ya chlorine dioxide (ClO₂) mu ruganda rw'ibinyobwa rudafite chlorine (ECF). Imiyoboro itwara umuti wa ClO₂ (igipimo cya 10-15 g/L nk'umuti ukoreshwa wa ClO₂) kuri 50-70°C hamwe n'umubare munini wa chloride (kuva kuri ClO₂ yakozwe). Imiyoboro ya 316L yabanje yagize ikibazo gikomeye cyo gushonga no kwangirika kw'imiyoboro, bisaba gusimburwa buri myaka 3-4. TP317L yatoranijwe kubera ko ifite ubushobozi bwo kurwanya imiyoboro myinshi (PREN 28-32 vs 24-26).
Ibibazo bya tekiniki n'ibisubizo:
Gushonga kw'ibice muri serivisi ya ClO₂– ClO₂ ni ikintu gikomeye gitera ogisijeni gitera imbaraga mu byuma bitagira umugese. Ubushobozi bwo gushyiramo imyanda bwa 316L buri hasi kuri 60°C. TP317L ifite Mo iri hejuru (3.2-3.6%) ifite ubushobozi bwo kwirinda imyanda bwinshi. Womic yakoze ikizamini cya G48 kuri 25°C na 40°C ku byuma by'ibanze n'ibipimo byo gusukamo imyanda. Kuri 25°C: nta myanda ishyirwamo imyanda ku byuma byose. Kuri 40°C: imyanda mito yatangiye gusukamo imyanda nyuma y'amasaha 72 ku byuma byo gusukamo imyanda (byemewe kuko ubushyuhe bwo gukora ari 60°C ariko igihe cyo gukorana nabyo ni gito). Umukiriya arabyemerewe.
Ubudahangarwa bw'icyuma gishongeshwa– Umugozi wo gusuka wa ERW ni wo ukunze kwangirika cyane. Womic yagenzuye ubushyuhe bugera kuri ≤ 1.3 kJ/mm kandi yakoresheje uburyo bwose bwo gufunga. Ikizamini cyo gusuka (G48, 25°C, amasaha 72) nta mwobo cyagaragaje ku mugozi wo gusuka. Igipimo cya Mo cya weld cyari 3.0-3.2% (kiri munsi gato y'icyuma cy'ibanze ariko cyemewe). Umukiriya yemewe.
Ubudahangarwa bw'ingese hagati y'udusate– TP317L ifite karuboni nkeya (≤ 0.03%). Ingano ya karuboni yagenzuwe n'abagore kuri buri bushyuhe (0.015-0.022%) nyayo. Ikizamini cya ASTM A262 Practice E (amasaha 120 muri aside sulfate-sulfuric y'umuringa) nta ngaruka zagaragaye. Nta ngaruka zagaragaye.
Impact ya Charpy mu gushyiraho ibikoresho by'igihe cy'itumba muri Kanada– Uru ruganda ruri mu majyaruguru ya BC aho ubushyuhe bw'itumba bugabanuka bukagera kuri -30°C. Imiyoboro ishyirwamo mu gihe cy'itumba isaba gukomera. Womic yakoze ibizamini bya Charpy V-Notch kuri -20°C na -40°C. Ibisubizo: icyuma cyo hasi kuri -40°C 60-90J, cyasuwe kuri -40°C 45-70J – hejuru cyane y'ibisabwa kuri 27J. Umukiriya yemerewe gushyirwamo mu gihe cy'itumba.
Gusudira TP317L mu gihe cy'ubukonje– Itsinda rishinzwe kubungabunga uruganda ryari rikeneye WPS yujuje ibisabwa kugira ngo ikoreshwe mu gusana mu gihe cy'itumba. Womic yatanze WPS ikoresheje GTAW ifite ER317L filler, ishyushya 10-20°C (kugira ngo hirindwe ko amazi ahinduka), interpass ≤ 150°C, ubushyuhe bugera kuri ≤ 1.5 kJ/mm. Kuponi 20 zo gusudira zatsinze RT, PT, n'ikizamini cyo gupima.
Ibikoresho bijya mu ruganda rwa kure rwa BC– Imiyoboro yoherejwe iva i Shanghai ijya i Vancouver, hanyuma ijyanwa na gari ya moshi igera kuri Prince George, hanyuma ijyanwa mu ruganda rw’amakamyo (urugendo rw’iminsi 45). SGS yagenzuwe i Vancouver. Toni 22 zose zatanzwe ku gihe nta cyangiritse.
Ibisubizo:Imiyoboro mishya ya TP317L yashyizweho mu kwezi kwa gatatu kwa 2023. Nyuma y'amezi 18 ikora, igenzura ryagaragaje ko nta mwobo warimo, nta kwangirika kw'imiyoboro, kandi nta gusohoka kw'amazi. Uru ruganda rwiteze ko rushobora gukora imyaka irenga 10 (ugereranije n'imyaka 3-4 kuri 316L). Umukiriya yagennye TP317L ku miyoboro yose ya serivisi ya ClO₂ mu nganda zabo eshatu za BC. Womic Steel ubu ni yo sosiyete yemewe gutanga impuzandengo n'impapuro.
