1. Dulmar Guud - Sababta X65MS+Incoloy 825 loogu talagalay Adeegga Dhanaan
Gaaska dhanaan ee qoyan - oo ka kooban haydarojiin sulfide (H₂S), kaarboon laba ogsaydh (CO₂), iyo badanaa koloriin - waa mid ka mid ah deegaannada ugu daran ee dhuumaha birta kaarboon. Birta caadiga ah ee X65 si degdeg ah ayay u dhacdaa sababtoo ahdillaaca cadaadiska sulfide (SSC)iyoDildilaaca haydarojiin ee keena (HIC).
X65MS+Incoloy 825 tuubo bimetal ah oo lagu dahaadhaywaxaa si gaar ah loogu talagalay xaaladaha noocaas ah:
● Birta gadaal u taagan ee X65MS ee dibadda ahwaa nooc ka mid ah X65 oo wax laga beddelay oo adeeg dhanaan ah. Waxay leedahay kaarboon yar (≤0.10%), sulfur yar (≤0.002%), iyo adkaanta la xakameeyey (≤248 HV) si ay uga hortagto SSC iyo HIC sida uu qabo NACE MR0175 / ISO 15156.
●Dahaarka Gudaha ee Inner Incoloy 825 (UNS N08825)waa isku-darka nikkel-ka oo ka kooban 38-46% Ni, 19-23% Cr, 2.5-3.5% Mo, oo lagu daray naxaas iyo titanium. Waxay u adkaysataa H₂S, CO₂, koloriin sare, sulfur elemental ah, iyo asiidhyada dabiiciga ah ee ku baahsan pH ballaaran iyo heerkulka.
Labada lakab waxaa si joogto ah isugu xira isku xidh bir ah (isku xidhka duubka kulul + sameynta JCOE). Si ka duwan tuubo farsamo ahaan loo dahaadhay, waxaa jirakhatar ma jirto in dahaarka uu burburo, laalaabmo, ama daxal daloolo ah uu ku dhaco is-dhexgalka.
Isku-darkaani waa heerka warshadahaisu imaatinka gaaska dhanaan ee badda,khadadka socodka ee duritaanka gaaska aashitada (AGI),Khadadka quudinta dhirta Claus, iyoceelasha qashinka ee cadaadiska sare leh.

8. Su'aalaha Badiya La Weydiiyo (FAQ)
S1: Waa maxay faraqa u dhexeeya X65 iyo X65MS?
A: X65MS waa wax ka beddelka "adeeg dhanaan" ee X65. Waxay leedahay kaarboon hoose (≤0.10%), sulfur aad u hooseeya (≤0.002%), xakamaynta adkaanta adag (≤248 HV), iyo tijaabada SSC/HIC ee qasabka ah sida ku cad NACE MR0175. Heerka X65 kuma habboona H₂S qoyan.
S2: Maxaad u isticmaashaa Incoloy 825 halkii aad ka isticmaali lahayd 316L ama duplex adeeg dhanaan?
A: Incoloy 825 waxa ku jira nikkel sare (38-46%), kaas oo bixiya iska caabin aad u fiican oo ku wajahan SCC iyo SSC-da ay keento koloriin. Waxa kale oo uu iska caabiyaa asiidhyada yareeya (tusaale ahaan, HCl) iyo sulfur-ka curiyaha ah - xaaladaha ay 316L iyo duplex ku fashilmaan. Adeeg aad u daran oo dhanaan ah (H₂S sare + koloriin sare + elemental S), Incoloy 825 badanaa waa CRA-da ugu yar ee la aqbali karo.
S3: Dahaarka Incoloy 825 ma lagu dhejin karaa laftiisa mise bir kaarboon ah?
J: Haa. Incoloy 825 waxaa lagu dhejin karaa GTAW (TIG), GMAW (MIG), iyo SMAW. Si aad ugu xirto dahaarka dahaarka, isticmaal birta buuxinta Alloy 82 / 82i (ERNiCr-3) ama Alloy 625 (ERNiCrMo-3). Si aad ugu xirto dahaarka birta kaarboonka (tusaale ahaan, dahaarka alxanka), isticmaal lakab dhexe oo Alloy 309L ama 625 ah si aad uga fogaato milmida iyo dildilaaca.
S4: Alxanka tolmada ee dhererka dheer ma sidoo kale ma u adkaysta yahay adeeg dhanaan?
J: Haa. Gudbinta gudaha waxaa lagu dahaadhay buuxinta Incoloy 625 (Ni, Cr, Mo ka sarreeya 825). Dahaarka alxankan wuxuu bixiyaa iska caabin daxaleed oo siman ama ka wanaagsan marka loo eego dahaarka 825. Alxanka oo dhan waa 100% NDT oo la baaray oo la tijaabiyay adkaantiisa.
S5: Shahaadooyin noocee ah ayaa la siiyaa adeegga dhanaan?
A: Waxaan soo saarnaa shahaadooyin EN 10204 Nooca 3.1/3.2 ah oo ay ku jiraan falanqaynta kulaylka birta ee taageerada leh, adkaanta, warbixinnada tijaabada SSC iyo HIC (haddii la sameeyo), iyo sahanka adkaanta alxanka. Marka la codsado, waxaan bixinaa warqad u hoggaansanaan NACE MR0175.
S6: Waa maxay waqtiga caadiga ah ee hogaanka loogu talagalay tuubooyinka X65MS+Incoloy 825 ee la dahaadhay?
A: Dalabka koowaad: 14-18 toddobaad (waxaa ku jira soo iibsiga agabka adeegga dhanaan iyo shahaadada). Dalabyada ku celcelinta: 10-12 toddobaad. Kormeerka dhinac saddexaad wuxuu ku dari karaa 1-2 toddobaad.
S7: Womic Steel ma bixin kartaa tuubo Inconel 625 ah oo la dahaadhay halkii ay ka keeni lahayd Incoloy 825?
J: Haa. Xaaladaha daran ee ka sii daran (heerkulka sare, H₂S sare, koloriin sare), waxaanu bixinaa tuubo X65MS+Inconel 625 (UNS N06625) ah. Inconel 625 wuxuu leeyahay xoog sare iyo iska caabin fiican oo ku saabsan godka (PREN >45). Nala soo xiriir si aad u hesho xog-warbixineed oo gaar ah.
