T1: Menene bambanci tsakanin X65 da X65MS?
A: X65MS wani gyara ne na "sabis mai tsami" na X65. Yana da ƙarancin carbon (≤0.10%), ƙarancin sulfur (≤0.002%), ƙarancin tauri mai ƙarfi (≤248 HV), da kuma gwajin SSC/HIC na tilas bisa ga NACE MR0175. Matsakaicin X65 bai dace da H₂S mai laushi ba.

T2: Me yasa ake amfani da Incoloy 825 maimakon 316L ko duplex don amfani da tsami?
A: Incoloy 825 ya ƙunshi babban nickel (38-46%), wanda ke ba da kyakkyawan juriya ga SCC da SSC da chloride ke haifarwa. Hakanan yana tsayayya da rage acid (misali, HCl) da elemental sulfur - yanayi inda 316L da duplex za su gaza. Ga matsanancin aiki mai tsami (babban H₂S + babban chlorides + elemental S), Incoloy 825 sau da yawa shine mafi ƙarancin CRA da aka yarda da shi.

T3: Za a iya haɗa rufin Incoloy 825 da kansa ko kuma da ƙarfen carbon?
A: Eh. Ana iya haɗa Incoloy 825 ta hanyar GTAW (TIG), GMAW (MIG), da SMAW. Don haɗa rufin da rufin, yi amfani da ƙarfe mai cika Alloy 82 / 82i (ERNiCr-3) ko Alloy 625 (ERNiCrMo-3). Don haɗa rufin da ƙarfe mai carbon (misali, rufin walda), yi amfani da matsakaicin Layer na Alloy 309L ko 625 don guje wa narkewa da tsagewa.

Q4: Shin walda mai tsayin daka shima yana da juriya ga aikin tsami?
A: Eh. An haɗa na'urar cika ciki da Incoloy 625 (mafi girma Ni, Cr, Mo fiye da 825). Wannan na'urar rufewa ta walda tana ba da juriyar tsatsa daidai ko mafi kyau fiye da na'urar rufewa ta 825. An duba dukkan na'urar NDT 100% kuma an gwada tauri.

T5: Waɗanne takaddun shaida ake bayarwa don hidimar tsami?
A: Muna bayar da takaddun shaida na EN 10204 Type 3.1/3.2 waɗanda suka haɗa da nazarin zafi na ƙarfe mai goyan baya, tauri, rahotannin gwaji na SSC da HIC (idan an yi su), da kuma binciken tauri na walda. Idan an buƙata, muna ba da wasiƙar bin ƙa'ida ta NACE MR0175.

T6: Menene lokacin jagora na yau da kullun don bututun X65MS+Incoloy 825 mai rufi?
A: Umarni na farko: makonni 14-18 (ya haɗa da siyan kayan aiki masu tsami da cancanta). Maimaita umarni: makonni 10-12. Dubawa na ɓangare na uku na iya ƙara makonni 1-2.

T7: Shin Womic Steel zai iya samar da bututun Inconel 625 mai rufi maimakon Incoloy 825?
A: Eh. Ga mawuyacin yanayi (zafin jiki mai yawa, H₂S mai yawa, yawan chlorides), muna bayar da bututun X65MS+Inconel 625 (UNS N06625). Inconel 625 yana da ƙarfi mafi girma da kuma juriyar rami mai kyau (PREN >45). Tuntuɓe mu don samun takardar bayanai daban.
