Q: Ni irihe tandukaniro riri hagati ya Inconel 625 (N06625) na Incoloy 825 (N08825)?
A: Inconel 625 ifite nikeli iri hejuru (iminota 58 ugereranije na 38-46%), molybdenum iri hejuru (8-10% ugereranije na 2.5-3.5%), kandi ikubiyemo niobium (3.15-4.15%). Ifite imbaraga nyinshi cyane (umusaruro wa 415 MPa ugereranije na 240 MPa), irwanya cyane imyobo (PREN 45-50 ugereranije na 30-35), n'ubushobozi bwo hejuru bw'ubushyuhe (980°C ugereranije na 550°C). Incoloy 825 irahendutse kandi ihagije kuri serivisi nyinshi za aside; Inconel 625 ikoreshwa mu bihe bikomeye cyane (amazi y'inyanja afite ubushyuhe bwinshi, serivisi y'amazi afite H₂S nyinshi, aside nyinshi z'ubushyuhe).
Q: Ese ni ngombwa ko imiyoboro ya Inconel 625 isukurwa ikoreshwa mu gufunga umuti?
A: Yego, kuri ASTM B705. Alloy 625 ishobora gukora ibice by’ubushyuhe (delta, Laves) mu gace kagizweho ingaruka n’ubushyuhe iyo ubukonje butinze. Gutera umuti ku bushyuhe bwa 1120-1180°C hagakurikiraho amazi yo kuzimya ibi bice bigasubizaho ubushobozi bwo kurwanya ingese no guhindagurika. Womic ikora uburyo bwose bwo gutera umuti ku miyoboro yose ya Alloy 625.
Q: Ese Inconel 625 ishobora gukoreshwa mu mazi yo mu nyanja?
A: Yego, Inconel 625 ifite ubushobozi bwo kurwanya ingese n'ibiturika mu mazi yo mu nyanja, ndetse no mu bushyuhe buri hejuru (ubushyuhe bukomeye bwo gutwika ibiturika > 100°C). Ikunze gukoreshwa mu mapompo yo kuzamura amazi yo mu nyanja, sisitemu z'amazi y'umuriro, n'ibice byo munsi y'inyanja mu mazi y'ubujyakuzimu. Ku mazi menshi yo mu nyanja, super duplex 2205 cyangwa 2507 irahagije; Alloy 625 igenewe ikirere gikaze cyane (ubushyuhe bwinshi, chlorine nyinshi, serivisi mbi hamwe n'amazi yo mu nyanja).
Q: Ese Inconel 625 ikwiriye gukoreshwa mu gutanga serivisi nziza (H₂S)?
A: Yego. Alloy 625 yujuje ibisabwa kuri NACE MR0175/ISO 15156 kugira ngo ikoreshwe mu buryo bwa sour hamwe n'umuvuduko wa H₂S ugera kuri bar 10 (150 psi) no hejuru, nta mbogamizi z'ubukana (igihe cyose umuti ufashwe neza). Akenshi ikoreshwa mu miyoboro yo munsi y'amazi, inzira zo munsi y'inyanja, n'ibice by'amazi mu mirima irimo sour nyinshi aho duplex na super duplex bidahagije.
Q: Ni ubuhe bushyuhe ntarengwa bwa serivisi ya Inconel 625?
A: Inconel 625 ifite ubushobozi bwo kurwanya ogisijeni kugeza kuri 980°C (1800°F) mu kirere. Ku bijyanye n'umuvuduko, imivuduko yemewe muri ASME Igice cya VIII itangwa kugeza kuri 815°C (1500°F). Ku bushyuhe buri hejuru (hejuru ya 980°C), izindi alloys nka Inconel 600, 601, cyangwa 617 zishobora gukenerwa.
Q: Ni ubuhe buryo bwo gusudira bw'icyuma busabwa kuri Inconel 625?
A: AWS A5.14 ERNiCrMo-3 (Inconel 625 filler) ni yo yuzuza ikoreshwa mu gusudira N06625. Mu guhuza Alloy 625 n'izindi alloys (urugero: icyuma cya karuboni, duplex), ERNiCrMo-3 nayo ikunze gukoreshwa. Womic ikoresha ERNiCrMo-3 mu gutunganya EFW.
Q: Ni ryari igihe gisanzwe cyo gukoresha umuyoboro wa UNS N06625 uhujwe?
A: Iminsi 90-120 kuri ERW (ubugari buto kugeza ku buringanire), iminsi 120-150 kuri EFW/LSAW (ubugari bunini). Igihe cy'ubugari ni kirekire cyane kurusha icy'ibyuma bitagira umugese kuko agace k'icyuma/isahani gakorwa mu bwinshi buto hamwe n'igihe kirekire cy'ubugari (akenshi ibyumweru 16-24). Igenzura ry'umuntu wa gatatu ryongeraho iminsi 14-21.
Q: Ni gute wakwirinda kwanduza icyuma ku miyoboro ya Alloy 625?
A: Womic ikoresha ibikoresho byabugenewe byo gufata ibyuma bitagira umugese, imigozi, n'ibikoresho byo kubikamo imiyoboro yose ya nikeli. Ibikoresho by'icyuma cya karuboni birabujijwe. Imiyoboro ipfunyikwa mu gipfunyika cya pulasitiki nyuma yo kuyikuramo. Ku bijyanye n'ibikorwa by'ingenzi byo mu mazi no mu nganda za kirimbuzi, dutanga icyemezo cyo kugenzura ubwandu.
Icyitonderwa cy'umushinga – Umuyoboro w'amazi yo munsi y'inyanja mu gice cy'inyanja cya H₂S/Chloride nyinshi (Brezili)
Igihugu:Brezili (Ikibaya cya Santos, ikibaya cyabanje kuba umunyu, ubujyakuzimu bw'amazi 2200m)
Igipimo n'Icyiciro:ASTM B705 UNS N06625 (Inconel 625) – umuyoboro upfutse (ufite icyuma gikozwe muri Alloy 625, ntabwo ari alloy yuzuye kuri uyu mushinga – ariko dutanga umuyoboro wuzuye w’alloy ku bapfumu) – umushinga nyakuri: imiyoboro yo munsi y’inyanja ikoresha N06625 idafunze ariko twerekeza ku muyoboro upfutse. Guhindura: umushinga ukoresha N06625 ipfutse ku bapfumu bato bafite umurambararo muto (4″ na 6″).
Ingano n'ingano:
● OD 114.3mm (4″) × Gahunda ya 80S (8.56mm WIT) – metero 2.000 (hafi toni 25) – Uburyo bwa ERW (bukonje bukoreshwa nyuma yo gusudira kugira ngo burusheho kwihanganira)
● OD 168.3mm (6″) × Gahunda 80S (10.97mm WIT) – metero 1.500 (hafi toni 38) – Uburyo bwa ERW
● OD 60.3mm (2″) × Gahunda XXS (11.07mm WIT) – metero 3.000 (hafi toni 34) – Uburyo bwa ERW
Igiteranyo:Metero 6.500, hafi toni 97
Ibisobanuro:Impande za ASTM B705 UNS N06625 zakuwemo amazi n'ibinyampeke, zikozwe mu buryo bwa "bevel" (bevel nziza yo gusudira munsi y'inyanja). Isuzuma rya "hydrostatic" ku gitutu cya 1.5 × (igishushanyo mbonera cya 35 MPa). 100% UT (itsinda ry'ibice) hamwe na 100% RT ku bisudira byose (bikomeye). PMI kuri buri muyoboro. Isuzuma rya corruption ritegetswe kuri ASTM G48 Uburyo bwa A (6% FeCl₃, amasaha 72 kuri 40°C) – nta mwobo urimo. Iyubahirizwa rya NACE MR0175 ku bijyanye na serivisi ya sour (igitutu cya H₂S igice cya 0.5 bar). Ingufu za Charpy kuri -46°C (spec 27J, yagezweho 120-180J). Ubukana ntarengwa bwa 30 HRC (yagezweho kuri 22-26 HRC). Ikurikiranwa ryuzuye kuva kuri ingot kugeza ku muyoboro warangiye. Igenzura ry'umuntu wa gatatu ryakozwe na DNV Brazil.
Porogaramu:Imiyoboro yo munsi y'inyanja n'imiyoboro y'amazi mu murima urimo umunyu (Santos Basin). Amazi yakozwe arimo H₂S (0.5 bar partial pressure), CO₂, n'amazi afite chloride nyinshi (100.000 ppm Cl⁻) kuri 80°C. Ingano irwanya ingese (CRA) irakenewe. Ingano 625 yatoranijwe kubera ko irwanya imyanda, SSC, na HIC muri ubu buryo bukabije.
Ibibazo bya tekiniki n'ibisubizo:
1. Serivisi ikarishye cyane (H₂S nyinshi + kloride nyinshi + ubushyuhe bwinshi)– Uruvange rwa H₂S (0.5 bar) na 100.000 ppm Cl⁻ kuri 80°C rurenze ubushobozi bwa super duplex. Alloy 625 ifite nickel na molybdenum nyinshi irwanya gucika kw'imiturire no kwangirika kwa sulfide. Womic yakoze ikizamini cya HIC na SSC hakurikijwe NACE TM0284 na TM0177. HIC: CLR 0%, CTR 0%, CSR 0%. SSC (Uburyo A, 720h kuri 90% SMYS muri 0.5 bar H₂S): nta gucika.
2. Impamyabushobozi yo gusudira munsi y'inyanja mu gukora jumpers– Ama-jumper asaba gusudira mu murima (umuyoboro ujya kuri flange) hakoreshejwe tekiniki yo gusudira ya kure (hyperbaric). Womic yatanze ama-coupons 30 yo gusudira hamwe na WPS isabwa hakoreshejwe GTAW, ERNiCrMo-3 filler, gushyushya mbere ya 10-20°C, interpass ≤ 120°C, input y'ubushyuhe ≤ 1.2 kJ/mm. Ama-coupons yanyuze kuri RT, PT, tensile, na Charpy kuri -46°C (suld 110-160J). Rwiyemezamirimo wo gusudira w'umukiriya niwe wujuje ibisabwa.
3. Ubwiza buto bw'ibihuza munsi y'inyanja– Amapine yo munsi y’inyanja akoresha uburyo bwo guhuza ibyuma bisaba uburebure bwa ≤ 0.2% bya OD. Uburyo bwo gukoresha ERW neza bukurikizaho gushushanya no gutunganya ibyuma. Uburyo bwo gupima uburebure bwa nyuma: umuyoboro wa 4″ 0.12-0.18%, umuyoboro wa 6″ 0.10-0.15%, umuyoboro wa 2″ 0.08-0.12%. Byose byaratsinzwe.
4. Gupima ingese ku bushyuhe buri hejuru (40°C muri FeCl₃)– Uburyo bwa G48 A ni ubushyuhe busanzwe bwa 22°C; umukiriya akeneye ubushyuhe bwa 40°C (bukabije cyane). Womic yakoze isuzuma ry’ibice ku bushyuhe bwa 40°C mu gihe cy’amasaha 72 – nta bice byashyizwemo ku gipimo icyo ari cyo cyose (icyuma cy’ibanze cyangwa icupa). Ubudahangarwa bw’ibice byakoreshejwe mu icupa rya weld bwagenzuwe ko bungana n’icyuma cy’ibanze.
5. Uburyo bwo gukurikirana ibintu kuva ku muyoboro w'ingot kugera ku muyoboro warangiye– Porogaramu zo munsi y’inyanja zisaba uburyo bwose bwo gukurikirana ibikoresho. Womic yatanze nimero zihariye z’imiyoboro kandi yakurikiranye buri muyoboro kuva ku nomero y’ubushyuhe kugeza ku igenzura rya nyuma. Ipaki y’inyandiko yari irimo impapuro 1.200 za MTC, raporo za NDT, n’ibyavuye mu isuzuma rya corruption. DNV yagenzuwe kandi yemeza.
6. Ibikoresho bijya mu busitani bw'ibikoresho bya Santos Basin– Imiyoboro yoherejwe iva i Shanghai ijya i Rio de Janeiro, hanyuma ijyanwa mu ruganda rw’ibicuruzwa i Niterói. DNV yabonye imiyoboro ipakiye. Toni 97 zose zatanzwe mu buryo butatu mu mezi 5. Imiyoboro ya nyuma yihutishijwe kugira ngo ihuze n’igihe ntarengwa cy’umushinga (imiyoboro y’indege ya toni 10 z’imiyoboro ya santimetero 2).
Ibisubizo:Ama-jumper yo munsi y’inyanja yashyizweho mu gihembwe cya mbere cya 2024. Nyuma y’amezi 12 yo gukorwa, nta kwangirika cyangwa gucikagurika byaragaragaye. Umukoresha yashyizeho uburyo bwa Alloy 625 ku ma-jumper yose yo mu bwoko bwa sour service mu mirima itarashyirwamo umunyu. Womic Steel ubu ni umucuruzi wujuje ibisabwa n’uyu mukoresha ku bijyanye n’imiyoboro ya CRA.
