Umuyoboro w'icyuma kitagira umugese wa ASTM A312 TP316N: Ubushobozi bwo gukora n'ibisobanuro by'ibicuruzwa

Kuki twafatanya na Womic Steel mu gukwirakwiza umuyoboro wa TP316N Welded?

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

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

Ingano ya azote yagenzuwe (0.10-0.16%) kugira ngo igaragare ko ifite imbaraga nyinshi.

Ingufu nyinshi zemerera inkuta zoroshye - kugabanya ibiro byazo kuva kuri 20-25% ugereranyije na 316.

Ubudahangarwa bw'imiyoboro y'amazi bwarushijeho kwiyongera (PREN iri hejuru ya 316).

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

Ibibazo Bikunze Kubazwa (Ibibazo Bikunze Kubazwa) - Umuyoboro wa ASTM A312 TP316N Welded

Q: Ni iyihe nyungu ya TP316N ugereranyije na 316 isanzwe?
A: TP316N ifite imbaraga zo gutanga umusaruro ku kigero cya 35% (275 MPa vs 205 MPa) kandi ifite ubushobozi bwo kurwanya imyobo (PREN 27-30 vs 24-26) mu gihe ikomeza kurwanya ingese, ubushobozi bwo gupfuka no gusudira. Ibi bituma abashushanya bakoresha inkuta nto ku miyoboro y'umuvuduko n'imiyoboro, bakagabanya uburemere ku kigero cya 20-25% kandi bakagabanya ikiguzi cy'ibikoresho muri rusange ku gipimo kimwe cy'umuvuduko.

Q: Ese TP316N irahenze kurusha 316?
A: Biterwa gato no gushyira azote mu cyuma no kugenzura cyane imiterere yacyo. Ariko, kuzigama uburemere (inkuta ndende 20-25%) akenshi bituma ikiguzi cy’ibikoresho muri rusange kigabanuka. Ku bijyanye n’imiterere y’icyuma aho imbaraga ari ingenzi, kugabanya uburemere bishobora kugabanya igiciro cy’icyuma kiri hejuru.

Q: Ese TP316N ishobora gukoreshwa mu gutanga serivisi ku mazi yo mu nyanja?
A: TP316N ifite ubushobozi bwo kwirinda imyobo kurusha 316, ariko kugira ngo amazi yo mu nyanja akomeze kwinjizwa mu kirere, duplex 2205 cyangwa super duplex birasabwa. TP316N ishobora kwemerwa mu gace ka splash, mu gukoraho hagati, cyangwa mu mazi yo mu nyanja afite umuvuduko muto mu bushyuhe buri munsi ya 30°C. Ku bushyuhe buri hejuru cyangwa chloride nyinshi, tekereza kuri super duplex.

Q: Ese TP316N isaba gukururwa n'umuti nyuma yo gusudira?
A: ASTM A312 isaba gufunga imiyoboro ivanze. Kuri TP316N, gufunga imiyoboro ku bushyuhe bwa 1040-1120°C hagakurikiraho gufunga amazi ni ngombwa kugira ngo hashongeshwe nitride zishobora kuba zarakozwe mu gihe cyo gusudira no kugarura ubushobozi bwose bwo kurwanya ingese n'imiterere ya mekanike. Womic ikora gufunga imiyoboro yose ivanze ya TP316N.

Q: Ni iyihe stress isanzwe yemewe kuri TP316N muri ASME Igice cya VIII?
A: Ku bushyuhe bw'icyumba, umuvuduko wemewe wa TP316N ni hafi 138 MPa (20.000 psi) ugereranije na 115 MPa (16.700 psi) kuri 316 - hafi 20% hejuru. Agaciro nyako gaterwa n'ubushyuhe; reba Igice cya II cya ASME, Igice cya D. Abashushanya bagomba gukoresha agaciro gakwiye k'umuvuduko wemewe ku rwego runaka.

Q: Ni ryari igihe gisanzwe cyo gukoresha umuyoboro w'icyuma kitagira umugozi wa TP316N?
A: Iminsi 25-35 kuri ERW (umurambararo muto kugeza kuri hagati), iminsi 35-50 kuri EFW/LSAW (umurambararo munini). Igihe cyo gukoresha TP316N gisa na 316.

Q: Ese TP316N ishobora gukoreshwa mu gutanga serivisi y'ubushyuhe bwinshi (irenga 500°C)?
A: Ingufu z'ubushyuhe bwinshi bwa TP316N ziruta 316 bitewe no kongera imbaraga za azote. Ariko, kugira ngo serivisi ikomeze hejuru ya 550°C, amanota afite karuboni nyinshi (316H, 316Ti) cyangwa amanota adashobora gukururwa (321H, 347H) ashobora kuba meza bitewe n'imiterere myiza yo gukururwa. TP316N ikwiriye cyane ubushyuhe buringaniye (<450°C) aho ingufu zikenewe.

Icyitonderwa cy'umushinga – Uburasirazuba bwo Hagati bwo Gukuraho Umunyu mu Miyoboro Ifite Umuvuduko Ukabije wa SWRO

Igihugu:Ibihugu by'Abarabu (Abu Dhabi)
Igipimo n'Icyiciro:ASTM A312 TP316N (isutswe)
Ingano n'ingano:

OD 219.1mm (8″) × Gahunda ya 10S (3.76mm WIT) – metero 1.500 (hafi toni 28) – Uburyo bwa EFW

OD 168.3mm (6″) × Gahunda ya 10S (3.40mm WIT) – metero 2.000 (hafi toni 24) – Uburyo bwa ERW

OD 114.3mm (4″) × Gahunda ya 10S (3.05mm WIT) – metero 2,500 (hafi toni 20) – Uburyo bwa ERW

OD 60.3mm (2″) × Gahunda ya 10S (Uburemere bwa 2.77mm) – metero 3.000 (hafi toni 11) – Uburyo bwa ERW
Igiteranyo:Metero 9.000, hafi toni 83

Ibisobanuro:Ingano za ASTM A312 TP316N zakuwemo amazi n'ibinyampeke, zikozwe mu buryo bwa "beveled". Isuzuma rya "hydrostatic" ku gitutu cya 1.5 × (igishushanyo mbonera cya 4.0 MPa, isuzuma rya 6.0 MPa). 100% UT ku miyoboro ya EFW, umuyoboro wa eddy kuri ERW. PMI kuri buri muyoboro. Isuzuma rya "tensile" (umusaruro ≥ 275 MPa, wageze kuri 310-350 MPa; "tensile ≥ 550 MPa", wageze kuri 580-630 MPa). Ingufu za Charpy kuri 0°C (uburemere bwa 27J, wageze kuri 90-140J). Isuzuma rya "pitting corrosion" kuri ASTM G48 Uburyo bwa A (amasaha 24 kuri 22°C) - nta mwobo urimo. Igenzura rya gatatu rikorwa na BV (Ibiro Veritas) UAE.

Porogaramu:Imiyoboro ifite umuvuduko mwinshi ku ruganda rukuraho amazi yo mu nyanja (SWRO) ruri i Abu Dhabi. Iyi miyoboro itwara amazi yo mu nyanja kuri 25-35°C, umunyu wa 45.000 ppm (Arabian Gulf), ku muvuduko wa 4.0 MPa (580 psi). Imiyoboro ya 316L yari isanzwe ihagije mu kwangirika ariko yasabaga inkuta nini kugira ngo zihangane n'umuvuduko, bigatuma uburemere n'ikiguzi byiyongera. TP316N yatoranijwe kubera imbaraga zayo nyinshi (275 MPa ugereranyije na 316L's 170 MPa), bituma inkuta za Schedule 10S zigira umuvuduko muto aho kuba Schedule 40S, bigatuma ibiro bya Schedule 10S bigabanukaho 55% kandi bikagabanya ikiguzi cyo gushyigikira inyubako.

Ibibazo bya tekiniki n'ibisubizo:

Ubudahangarwa bw'amazi yo mu nyanja yo mu kigobe cya Arabiya– Ubushyuhe bw'amazi yo mu nyanja ni 35°C mu mpeshyi, umunyu ni 45.000 ppm. 316L byaba ari umupaka. TP316N ifite PREN iri hejuru (27-30 ugereranije na 316L 24-26) yatanze ubushobozi bwo guhangana n'imyobo. Womic yakoze ikizamini cya G48 kuri 22°C na 35°C (cyakozwe mu mpeshyi) – nta myobo yashyizwe kuri 22°C; kuri 35°C, imyobo mike yatangiye gushirwa nyuma y'amasaha 72 ku bipimo byo gusudira, ariko byemewe ku gihe cy'imyaka 25 gishushanyijeho hamwe n'uburinzi bwa cathodic. Umukiriya arabyemerewe.

Kugabanya ibiro hakoreshejwe Gahunda ya 10S– Imbaraga nyinshi za TP316N zemereye Schedule 10S (3.76mm kuri 8″) aho gukoresha Schedule 40S (8.18mm) kuri 316L. Uburemere bwagabanutse kuva kuri toni 1.14 kuri 12m bugera kuri toni 0.52 kuri 12m – 54% by'ubwizigame. Kuzigama uburemere bwose bw'umushinga: toni 97 (toni 180 z'umwimerere ugereranije na toni 83 nyazo). Womic yatanze imibare y'ingufu z'igishushanyo hakurikijwe ASME B31.3.

Guhuza imbaraga z'icyuma cyo gusudira– ERW na EFW welds zigomba kugira imbaraga zingana n'iz'icyuma cyo hasi kugira ngo zirusheho kugira imbaraga zemewe. Ibipimo bya ERW bya Womic byakozwe neza kugira ngo bigere ku buhanga bw'ingingo zo hasi bwa 95% (imbaraga zo gukurura 590 MPa vs base 610 MPa). EFW welds zikoresheje ER316N filler zageze ku buhanga bw'ingingo bwa 100%. Ibizamini byose byo gukurura ibyuma byo hasi byatsinze ku gipimo cya 6.0 MPa hifashishijwe hydrotest.

Uburyo bwo gusudira mu murima kuri TP316N– Rwiyemezamirimo wo gushyiraho ibikoresho yari akeneye WPS yujuje ibisabwa. Womic yatanze ama coupons 20 yo gusudira hamwe na WPS akoresheje GTAW hamwe na ER316 filler (nta filler yihariye ya N), interpass ≤ 150°C, ubushyuhe butanga ≤ 1.5 kJ/mm. Kuponi zatsinze RT, PT, na tensile test. Umukiriya yujuje ibisabwa.

Ibikoresho bijyana muri Abu Dhabi– Imiyoboro yoherejwe iva i Shanghai ijya ku cyambu cya Khalifa mu buryo bubiri. BV yagenzuye imiyoboro aho imizigo yapakirwaga. Toni 83 zose zatanzwe mu byumweru 6. Nta kutubahiriza amategeko

Ibisubizo:Imiyoboro y'amazi yo mu mazi ya SWRO yashyizwe mu gihembwe cya kabiri cya 2024. Nyuma y'amezi 12 ikora kuri 4.0 MPa, 35°C y'amazi yo mu nyanja, nta mwobo cyangwa ingese byagaragaye. Kugabanya uburemere bwa toni 97 byagabanyije ikiguzi cy'icyuma cyubatswe ku nyubako ku toni 40, bigabanya amafaranga y'ubwubatsi y'amadolari 250.000. Uyu mukiriya yakoresheje TP316N nk'igipimo gisanzwe cyo gukoresha imiyoboro y'amazi yo mu mazi yo mu mazi yo mu Burasirazuba bwo Hagati mu nganda zabo zo gukuramo umunyu mu mazi.
