10. Ibyiza n'Ibibazo Bikunze Kubazwa mu byuma bya Womic Steel – Umuyoboro wa ASTM A312 TP304LN Udafite Umugozi Udapfutse
Kuki wafatanya na Womic Steel mu gukwirakwiza umuyoboro udafite umugozi wa TP304LN?
Ingano yuzuye: Ifite ishusho ikonje 1/2″ – 8″, Ishyushye irangizwa 4″ – 24″.
Gufunga byuzuye (1040-1120°C, amazi yo kuzimya).
Ingano ya azote yemejwe (0.10-0.16%) - ifite imbaraga nyinshi zemejwe (275 MPa yinjiza umuvuduko).
Ingufu nyinshi zemerera inkuta zoroshye - kugabanya ibiro bya 25-30% ugereranyije na 304L.
Karuboni nkeya (≤ 0.03%) - ubushobozi bwo gusudira neza no kurwanya IGC.
Igihe cyo guhatana: iminsi 25-35 kuri CD, iminsi 35-50 kuri HF.

Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro w'icyuma kitagira umushongi wa ASTM A312 TP304LN
Q: Ni iyihe nyungu ya TP304L ugereranyije na 304L isanzwe?
A: TP304LN ifite imbaraga zo gutanga umusaruro ku kigero cya 60% (275 MPa ugereranyije na 170 MPa) bitewe n’inyongera ya azote, mu gihe ikomeza kurwanya ingese, ubushobozi bwo guhindagurika no gusudira. Ibi bituma abashushanya bakoresha inkuta nto ku miyoboro y’umuvuduko n’imiyoboro (kugabanya ibiro 25-30%) kugira ngo bagere ku gipimo kimwe cy’umuvuduko. Ku bijyanye n’inyubako, ingano nto y’ibice ishobora gukoreshwa.
Q: Ese TP304LN ihenze kurusha 304L?
A: Biterwa gato no gushyira azote mu cyuma no kugenzura cyane imiterere yacyo. Ariko, kuzigama uburemere (inkuta ndende 25-30%) akenshi bituma ikiguzi cy’ibikoresho muri rusange kigabanuka ku bikoresho bikoreshwa mu gushyiramo igitutu. Ku bikoresho by’ubwubatsi aho imbaraga ari ingenzi, kugabanya uburemere bishobora kugabanya igiciro cy’ibikoresho biri hejuru.
Q: Ese TP304LN ishobora gukoreshwa mu gutanga serivisi ku mazi yo mu nyanja?
A: Oya. TP304LN ifite ubushobozi bwo guhangana n’imyobo isa na 304L (PREN ≈ 19-20). Ku mazi yo mu nyanja cyangwa ahantu hafite chloride nyinshi, koresha 316LN (hamwe na Mo) cyangwa icyuma kitagira umugese gikozwe mu buryo bwa duplex. TP304LN ni iyo gukoresha chloride cyangwa chloride nkeya aho bikenewe imbaraga nyinshi.
Q: Ese TP304LN isaba gusukurwa nyuma yo gutunganywa?
A: ASTM A312 isaba gufunga imiyoboro idafite umugozi. Kuri TP304LN, gufunga imiyoboro ku bushyuhe bwa 1040-1120°C hagakurikiraho gufunga amazi ni ngombwa kugira ngo hashongeshwe nitride zose zishobora kuba zarakozwe mu gihe cyo gutunganya no kugarura ubushobozi bwose bwo kurwanya ingese n'imiterere ya mekanike. Womic ikora gufunga imiyoboro idafite umugozi ku miyoboro yose idafite umugozi ya TP304LN.
Q: Ni iyihe stress isanzwe yemewe kuri TP304LN muri ASME Igice cya VIII?
A: Ku bushyuhe bw'icyumba, umuvuduko wemewe wa TP304LN ni hafi 138 MPa (20.000 psi) ugereranije na 115 MPa (16.700 psi) kuri 304L - hafi 20% hejuru. Agaciro nyako gaterwa n'ubushyuhe; reba Igice cya II cya ASME, Igice cya D. Abashushanya bagomba gukoresha agaciro gakwiye kemewe k'umuvuduko wemewe ku rwego runaka.
Q: Ni ryari igihe gisanzwe cyo gutanga umuyoboro wa TP304LN udafite umugozi uhagije?
A: Iminsi 25-35 kuri CD (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri HF (umurambararo munini). Igihe cyo gukoresha TP304LN gisa na 304L. Igenzura ry’umuntu wa gatatu ryongeraho iminsi 7-14.
Q: Ese TP304LN ishobora gukoreshwa mu gutanga serivisi y'ubushyuhe bwinshi (irenga 500°C)?
A: Ingufu z'ubushyuhe bwinshi bwa TP304LN ziruta 304L bitewe no kongera ingufu za azote. Ariko, kugira ngo serivisi ikomeze hejuru ya 550°C, amanota afite karubone nyinshi (304H) cyangwa amanota adashobora gukururwa (321H, 347H) ashobora kuba meza bitewe n'imiterere myiza yo gukururwa. TP304LN ikwiriye cyane ubushyuhe buringaniye (<450°C) aho ingufu zikenewe.
Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri TP304LN?
A: AWS A5.9 ER308L (karubone nkeya) ikunze gukoreshwa. Kugira ngo hahuzwe ingano ya azote, ER308L filler irashobora gukoreshwa, ariko ER308L muri rusange yemerwa mu bikorwa byinshi. Karubone nkeya ya ER308L ibuza ubwiyongere bwa HAZ.
Icyitonderwa cy'umushinga – Uruganda rw'ubwato bukoresha ingufu mu Burayi (Ubudage)
Igihugu:Ubudage (Rhine y'Amajyaruguru-Westphalia)
Igipimo n'Icyiciro:ASTM A312 TP304LN (idafite umushono) – ASME Igice cya VIII cyubahiriza
Ingano n'ingano:
OD 219.1mm (8″) × Gahunda ya 10S (Uburemere bwa 4.76mm) – metero 600 (hafi toni 28) – Ishyushye cyane
OD 273.0mm (10″) × Gahunda ya 10S (Uburemere bwa 4.19mm) – metero 400 (hafi toni 22) – Ishyushye cyane
OD 60.3mm (2″) × Igipimo 40S (3.91mm WIT) – metero 1.200 (hafi toni 10) – Ifite ubukonje
OD 88.9mm (3″) × Igipimo 40S (Uburemere bwa 5.49mm) – metero 800 (hafi toni 12) – Ifite ubukonje
Igiteranyo:Metero 3.000, hafi toni 72
Ibisobanuro:ASTM A312 TP304LN ifite umushongi ugororotse, ifunze neza kandi ikaranze, impera zayo zikozwe mu gusudira. Isuzuma rya Hydrostatic. Umuyoboro wa Eddy (CD) na UT (HF). PMI kuri buri muyoboro. Isuzuma rya ngombwa ryo gukurura (umusaruro ≥ 275 MPa, wageze kuri 310-350 MPa; gukurura ≥ 550 MPa, wageze kuri 580-630 MPa). Ingufu za Charpy kuri 0°C (uburemere bwa 27J, wageze kuri 100-160J). Isuzuma rya Intergranular corrosion kuri ASTM A262 Practice E (pass). Igenzura rya gatatu ryakozwe na TÜV Germany.
Porogaramu:Ibikoresho by'imiyoboro y'umuvuduko n'iminwa y'iminwa ku ruganda rukora imiyoboro y'umuvuduko yemewe na ASME (ibikoresho byo kwakira umwuka, imiyoboro itunganya, imiyoboro ikora gaze). Imiyoboro ikora ku muvuduko ugera kuri 3.5 MPa hamwe n'imyuka n'amazi bidahumanya. TP304LN yatoranijwe kugira ngo igabanye uburemere bw'imiyoboro (inkuta nto) mu gihe igumana igipimo cy'umuvuduko gikenewe, ikagabanya ikiguzi cy'ibikoresho n'uburemere bwo kohereza.
Ibibazo bya tekiniki n'ibisubizo:
Kugabanya ibiro hakoreshejwe TP304LN– Uburemere bwinshi bwemewe bwa TP304LN (20% hejuru ya 304L kuri ASME Section VIII) bwatumye ubugari bw'inkuta bugabanuka kuva kuri 6.0mm kugeza kuri 4.8mm ku mashini za santimetero 8, bigatuma uburemere bwa buri bwato bugabanukaho 20%. Ku mashini 20, uburemere bwose bwagabanutseho toni 4.5. Abakiriya bemeye imibare y'igishushanyo mbonera yatanzwe n'itsinda ryabo ry'abahanga.
Uburyo bwo gusudira mu gukora ubwato– Gukora imiyoboro y’umuvuduko bisaba gusudira neza (SAW na GTAW). TP304LN ifite karubone nkeya (0.015-0.020%) na azote byatanze ubushobozi bwo gusudira neza. Womic yatanze ingero z’uburyo bwo gusudira (WPQ). Kuponi zatsinze ibizamini byo gukurura, gukota, na Charpy kuri 0°C.
Ubudahangarwa bw'ingese hagati y'udusate– Amato ashobora guhura n’ubushyuhe bukabije mu gihe cyo gutunganya ubushyuhe nyuma yo kuyasudira (niba buhari). TP304LN ifite karubone nke na azote byanyuze muri ASTM A262 Practice E nta ngaruka mbi ziterwa n’ibice by’ibumba.
Ubuziranenge bw'ibipimo byo gushyiramo insinga– Amajosi y'iminwa asaba ubushobozi bwo gushyiramo OD n'uburemere buhagije kugira ngo ihuzwe n'udupira. Imiyoboro ikonje yageze ku buremere bwa OD ± 0.1mm (ASME yemerera ± 0.5% cyangwa 1.1mm kuri 8″). Itsinda ry'abakora ibikoresho ryatangaje ko ihujwe neza.
Ibikoresho byo mu Budage– Imiyoboro yoherejwe iva i Shanghai ijya ku cyambu cya Hamburg, hanyuma ikajyanwa mu ruganda rw’uruganda. TÜV yagenzuwe ku cyambu. Toni 72 zose zatanzwe mu bicuruzwa 3 mu byumweru 8. Inyandiko zemewe.
Ibisubizo:Uruganda rukora ubwato bukoresha umuvuduko rwahinduye kuva kuri 304L rujya kuri 304LN ku miterere mishya y’ubwato, rugabanya uburemere bw’ubwato ku kigero cya 20-25% kandi rugabanya ikiguzi cyo kohereza. Womic Steel ubu ni yo isosiyete ikunda gutanga imiyoboro idafite umuvuduko kuri uru ruganda.
