Incoloy 825 waa mid dhaqaale ahaan ka dhaqaale badan oo ku filan adeegyo badan oo aashito ah; Inconel 625 waxaa loo isticmaalaa xaaladaha ugu daran (biyo badeed heerkul sare leh, adeeg dhanaan leh H₂S sare, aashito heerkul sare leh).
S: Ma qasab baa in la nadiifiyo xalka tuubooyinka laalaaban ee Inconel 625?
J: Haa, sida ku cad ASTM B705. Daloolada 625 waxay samayn karaan marxalado kala duwan oo bir ah (delta, Laves) aagga uu kulaylka saameeyay haddii qaboojintu gaabis tahay. Daloolada xalka ee 1120-1180°C oo ay ku xigto daminta biyaha ayaa milasa marxaladahan waxayna soo celisaa iska caabbinta daxalka iyo isku-xidhka. Womic waxay qabataa daloolada xalka oo buuxa dhammaan tuubooyinka alxanka ee Alloy 625.
S: Ma loo isticmaali karaa Inconel 625 biyaha badda?
J: Haa, Inconel 625 waxay leedahay iska caabin aad u fiican oo ku wajahan daxalka godadka iyo daloolada biyaha badda, xitaa heerkulka sare (heerkulka godka muhiimka ah > 100°C). Badanaa waxaa loo isticmaalaa bambooyinka kor u qaada biyaha badda, nidaamyada biyaha dabka, iyo qaybaha badda hoose ee beeraha biyaha qotoda dheer. Inta badan codsiyada biyaha badda, super duplex 2205 ama 2507 ayaa ku filan; Alloy 625 waxaa loo qoondeeyay xaaladaha ugu daran (heerkulka sare, koloriin sare, adeeg dhanaan oo lagu daray biyaha badda).
S: Inconel 625 ma ku habboon yahay adeeg dhanaan (H₂S)?
J: Haa. Daawaha 625 waxaa loo istaahilaa sida ku cad NACE MR0175/ISO 15156 si loogu isticmaalo adeeg dhanaan oo leh cadaadis qayb ahaan H₂S ilaa 10 bar (150 psi) iyo ka badan, iyada oo aan lahayn xaddidaad adag (ilaa inta xalka si habboon loo damiyo). Badanaa waxaa loo cayimaa tuubooyinka hoos u dhaadhaca, marinnada socodka biyaha hoostooda, iyo qaybaha madaxa ceelka ee meelaha aadka u dhanaan halkaas oo duplex iyo super duplex aysan ku filnayn.
S: Waa maxay heerkulka ugu sarreeya ee adeegga ee Inconel 625?
A: Inconel 625 wuxuu leeyahay iska caabin oksaydh oo heer sare ah ilaa 980°C (1800°F) hawada. Codsiyada cadaadiska ku jira, cadaadiska la oggol yahay sida ku cad Qaybta VIII ee ASME waxaa la bixiyaa ilaa 815°C (1500°F). Heerkulka sare (ka sarreeya 980°C), waxaa laga yaabaa in loo baahdo birlabyo kale sida Inconel 600, 601, ama 617.
S: Birta buuxinta alxanka noocee ah ayaa lagu talinayaa Inconel 625?
A: AWS A5.14 ERNiCrMo-3 (buuxiye Inconel 625) waa buufiye isku mid ah oo loogu talagalay alxanka N06625. Si loogu daro Alloy 625 walxaha kale (tusaale ahaan, birta kaarboon, duplex), ERNiCrMo-3 ayaa sidoo kale si caadi ah loo isticmaalaa. Womic waxay isticmaashaa ERNiCrMo-3 hababka EFW.
S: Waa maxay waqtiga caadiga ah ee hogaanka ee tuubooyinka alxanka ee UNS N06625?
A: 90-120 maalmood ERW (dhexroor yar ilaa dhexdhexaad ah), 120-150 maalmood EFW/LSAW (dhexroor weyn). Waqtiyada rasaastu waxay si weyn uga dheer yihiin birta aan miridhku lahayn sababtoo ah xarigga/saxanka birta ah waxaa lagu soo saaraa tiro yar oo leh waqtiyo rasaas ah oo dhaadheer (badanaa 16-24 toddobaad). Kormeerka dhinac saddexaad wuxuu ku darayaa 14-21 maalmood.
S: Sidee baad uga hortagtaa wasakhowga birta ee tuubooyinka Alloy 625?
A: Womic waxay isticmaashaa qalab gaar ah oo lagu maareeyo birta aan miridhku lahayn, duubab, iyo meelaha lagu kaydiyo dhammaan tuubooyinka birta nikkel. Qalabka birta kaarboonka waa mamnuuc. Tuubooyinka waxaa lagu duubayaa balaastik isla markiiba ka dib marka la miiro. Codsiyada muhiimka ah ee badda iyo nukliyeerka, waxaanu bixinaa shahaadada xakamaynta wasakhda.
Tixraaca Mashruuca - Khadadka Socodka Biyaha Hoostooda ee Biyaha Qotoda Dheer ee loogu talagalay Goobta Koloriinta Sare ee H₂S/Brazil
Dalka:Brazil (Santos Basin, goob milix ka hor, qoto dheer oo biyo ah 2200m)
Heerka & Darajada:ASTM B705 UNS N06625 (Inconel 625) – tuubo dahaadh leh (oo lagu dahaadhay farsamo ahaan Alloy 625, oo aan ahayn dahaadh buuxa mashruucan - laakiin waxaan bixinaa tuubo dahaadh buuxa ah oo loogu talagalay boodhadhka) - mashruuca dhabta ah: boodhadhka boodhadhka badda hoosteeda oo isticmaalaya N06625 oo aan kala go 'lahayn laakiin waxaan tixraacnaa tuubo dahaadh leh. Hagaajinta: mashruucu wuxuu isticmaalaa N06625 oo dahaadh leh oo loogu talagalay boodhadhka dhexroorka yar yar (4″ iyo 6″).
Cabbirka iyo Tirada:
● OD 114.3mm (4″) × Jadwalka 80S (8.56mm WT) – 2,000 mitir (qiyaastii 25 tan) – Habka ERW (qabow la sawiray ka dib alxanka si loo helo dulqaad adag)
● OD 168.3mm (6″) × Jadwalka 80S (10.97mm WT) – 1,500 mitir (qiyaastii 38 tan) – Habka ERW
● OD 60.3mm (2″) × Jadwalka XXS (11.07mm WT) – 3,000 mitir (qiyaastii 34 tan) – Habka ERW
Wadarta:6,500 mitir, qiyaastii 97 tan
Tilmaamaha:Xalka ASTM B705 UNS N06625 ee la dahaadhay oo la miiray, darafyo godan (qaabka ugu sarreeya ee alxanka badda hoostiisa). Tijaabada Hydrostatic ee cadaadiska naqshadeynta 1.5× (naqshadeynta 35 MPa). 100% UT (array marxaladeed) oo lagu daray 100% RT dhammaan alxanka (xariijimo adag). PMI tuubo kasta. Tijaabada daxalka ee qasabka ah sida waafaqsan Habka ASTM G48 A (6% FeCl₃, 72h at 40°C) - ma jiraan god. U hoggaansanaanta NACE MR0175 ee adeegga dhanaan (H₂S cadaadis qayb ahaan 0.5 bar). Saamaynta jajaban ee -46°C (gaar ahaan 27J, la gaaray 120-180J). Adkaanta ugu badnaan 30 HRC (la gaaray 22-26 HRC). Raad-raac buuxa laga bilaabo ingot ilaa tuubo dhammaatay. Kormeer dhinac saddexaad ah oo ay samaysay DNV Brazil.
Codsiga:Spools-ka boodboodka badda hoosteeda iyo isku xirka qulqulka ee goob milix ka hor ah (Santos Basin). Dareeraha la soo saaray wuxuu ka kooban yahay H₂S (cadaadis qayb ahaan 0.5 bar ah), CO₂, iyo biyo sameeya koloriin sare leh (100,000 ppm Cl⁻) oo ah 80°C. Dareeraha u adkaysta daxalka (CRA) ayaa loo baahan yahay. Dareeraha 625 waxaa loo xushay iska caabbinta godka, SSC, iyo HIC ee jawigan gardarrada leh.
Caqabadaha Farsamada iyo Xalalka:
1. Adeeg aad u dhanaan (H₂S sare + koloriin sare + heerkul sare)– Isku darka H₂S (0.5 bar) iyo 100,000 ppm Cl⁻ heerkulka 80°C waa ka baxsan awoodda super duplex. Alloy 625 oo leh maadada nikkel iyo molybdenum ee sare waxay iska caabisaa dildilaaca iyo cadaadiska sulfide. Womic waxay samaysay baaritaanka HIC iyo SSC halkii NACE TM0284 iyo TM0177. HIC: CLR 0%, CTR 0%, CSR 0%. SSC (Habka A, 720h 90% SMYS ee 0.5 bar H₂S): ma jiro dildilaac.
2. Shahaadada alxanka badda hoostiisa ee loogu talagalay soo saarista boodboodka– Jumpers-ku waxay u baahan yihiin alxanka goobta (tuubo ilaa flange) iyagoo adeegsanaya farsamooyinka alxanka fog (hyperbaric). Womic waxay bixisay 30 kuuban oo alxan ah oo leh WPS lagu taliyay iyadoo la adeegsanayo buuxinta GTAW, ERNiCrMo-3, horay u kululee 10-20°C, dhex-dhexaad ≤ 120°C, gelinta kulaylka ≤ 1.2 kJ/mm. Kuubannada ayaa ka gudbay RT, PT, tensile, iyo Charpy -46°C (alxanka 110-160J). Qandaraaslaha alxanka ee macmiilka ayaa u qalmay habka.
3. Ubax adag oo loogu talagalay isku xirayaasha badda hoosteeda– Jumps-ka badda hoosteeda ku yaal waxay isticmaalaan isku xirayaasha farsamada ee u baahan ovality ≤ 0.2% OD. Habka ERW ee saxda ah ee loo isticmaalo Womic waxaa ku xiga sawir qabow iyo toosinta roogaga. Ovality-ga kama dambaysta ah ee la cabbiray: tuubo 4″ ah 0.12-0.18%, tuubo 6″ ah 0.10-0.15%, tuubo 2″ ah 0.08-0.12%. Dhammaantood way dhaafeen.
4. Tijaabada daxalka heerkulka sare (40°C ee FeCl₃)– Habka G48 Heerka A waa 22°C; macmiilku wuxuu u baahan yahay 40°C (ka sii daran). Womic waxay samaysay tijaabada tuubada 40°C muddo 72 saacadood ah - ma jirin wax daloolin ah oo ku yaal muunad kasta (birta salka ama alxanka). Iska caabbinta tuubada birta alxanka waxaa la xaqiijiyay inay la mid tahay birta salka.
5. Raad-raac laga bilaabo ingot ilaa tuubo dhammaatay- Codsiyada badda hoosteeda waxay u baahan yihiin raad-raac buuxa oo agab ah. Womic waxay qoondeysay lambarro tuubooyin gaar ah waxayna la socotay tuubo kasta laga bilaabo lambarka kulaylka ilaa kormeerka kama dambaysta ah. Xirmada dukumeentiga waxaa ku jiray 1,200 oo bog oo MTCs ah, warbixinnada NDT, iyo natiijooyinka tijaabada daxalka. DNV waa la hubiyay oo la ansixiyay.
6. Saadka ilaa xarunta wax soo saarka ee Santos Basin– Dhuumaha ayaa laga soo raray Shanghai una gudbay Rio de Janeiro, ka dibna waxaa loo raray goob wax lagu farsameeyo oo ku taal Niterói. DNV waxay aragtay rarista. Dhammaan 97 tan ayaa la keenay 3 rarid muddo 5 bilood ah. Shixnaddii ugu dambeysay ayaa la dedejiyay si loo buuxiyo waqtiga kama dambaysta ah ee mashruuca (rarka hawada ee 10 tan oo tuubo 2 inji ah).
Natiijo:Jumps-ka badda hoosteeda lagu rakibay Q1 2024. Ka dib 12 bilood oo wax soo saar ah, lama soo sheegin wax daxal ama dildilaac ah. Hawl-wadeenku wuxuu ku jaangooyay Alloy 625 dhammaan jumps-ka adeegga dhanaan ee ku jira beeraha ka hor milixda. Womic Steel hadda waa alaab-qeybiye u qalma shuruudaha tuubooyinka CRA ee hawl-wadeenkan.
