Ipayipi Lensimbi Ehlanganisiwe ye-X65MS+Incoloy 825 | Ipayipi Elinezintambo ze-CRA Lensizakalo Engamanzi Yemvelo ye-H₂S ne-CO₂ – Insimbi Yomhlobiso

Incazelo emfushane:

Ipayipi Langaphandle (Insimbi Esekelayo):I-API 5L X65MS (PSL2) – izinga lesevisi elimuncu, ikhabhoni ephansi, isibabule esiphansi, ubulukhuni obulawulwayo, ukumelana ne-SSC

Ulwelwesi Lwangaphakathi (i-CRA Cladding):I-Incoloy 825 (UNS N08825) – i-nickel iron chromium alloy ene-molybdenum, ithusi, i-titanium; ukumelana okuhle kakhulu ne-H₂S, i-CO₂, ama-chloride, kanye nama-asidi anciphayo

Ububanzi Bosayizi:OD 219mm – 1016mm (8″ – 40″); Ubukhulu bodonga lwensimbi esekelayo 10mm – 30mm; Ubukhulu bokumboza 2.0mm – 3.5mm; Ubude obubodwa bufika ku-18m (kuyatholakala ama-24m ngokwezifiso)

Inqubo Yokukhiqiza:Ukubopha okugoqekayo okushisayo + ukwakha i-JCOE – amandla okushefa esixhumi se-metallurgical bond ≥200 MPa; ukumbozwa kokushisela kumthungo

Amazinga kanye Nezitifiketi:I-API SPEC 5LD (Ipayipi Lensimbi Elimboziwe le-CRA), i-DNV-OS F101, i-NACE MR0175 / ISO 15156 (ihambisana ne-SSC/HIC), i-ISO 13623. Isitifiketi Sokugaya EN 10204 Uhlobo 3.1/3.2. Ukuhlolwa kweqembu lesithathu (i-SGS, i-BV, i-DNV, i-TÜV, i-ABS, i-LR) kuyatholakala.

Izicelo:Amapayipi egesi emuncu emanzi, izinhlelo zokuqoqa igesi ze-H₂S eziphezulu, imithombo yokufaka igesi ene-asidi (imigqa yokugeleza kwamanzi ebusweni), imigqa yokudla yezitshalo ze-Claus sulfur, ukulahla amanzi e-CO₂−H₂S ngomfutho ophezulu.

Insimbi YaseWomicihlinzeka ngepayipi elimbozwe ngensimbi le-X65MS+Incoloy 825 – ikhambi eliqinisekisiwe lenkonzo emuncu kakhulu. Insimbi esekelayo ihlangabezana nobunzima be-NACE MR0175 ≤248 HV; I-Incoloy 825 cladding imelana ne-SSC, HIC, kanye nokugqwala okujwayelekile kwe-H₂S/CO₂/Cl⁻. Ibhalwe phansi ngokugcwele futhi ukuhlolwa komuntu wesithathu sekulungile.

Amathegi Omkhiqizo

1. Ukubuka Konke – Kungani i-X65MS+Incoloy 825 Yesevisi Engacacile

Igesi elimanzi elimuncu – eliqukethe i-hydrogen sulfide (H₂S), i-carbon dioxide (CO₂), kanye nama-chloride ngokuvamile – ingenye yezindawo eziyingozi kakhulu zamapayipi ensimbi yekhabhoni. Insimbi ejwayelekile ye-X65 iyaphela ngokushesha ngenxaukuqhekeka kokucindezeleka kwe-sulfide (SSC)futhiukuqhekeka okubangelwa yi-hydrogen (HIC).

Ipayipi elimbozwe nge-bimetal le-X65MS+Incoloy 825yenzelwe ngqo izimo ezinjalo:

● Insimbi esekelayo yangaphandle ye-X65MSiyinguqulo ye-X65 eguquliwe nge-sour-service. Ine-carbon ephansi (≤0.10%), i-sulfur ephansi (≤0.002%), kanye nokuqina okulawulwayo (≤248 HV) ukumelana ne-SSC kanye ne-HIC njengoba kudingeka yi-NACE MR0175 / ISO 15156.

●Isimbozo se-Inner Incoloy 825 (UNS N08825)iyi-alloy esekelwe ku-nickel equkethe i-38-46% Ni, 19-23% Cr, 2.5-3.5% Mo, kanye nethusi ne-titanium. Imelana ne-H₂S, i-CO₂, ama-chloride aphezulu, i-elemental sulfur, nama-organic acids kulo lonke ububanzi be-pH kanye nobubanzi bokushisa.

Lezi zingqimba ezimbili zihlanganiswa unomphela yisibopho sensimbi (isibopho se-hot roll + i-JCOE forming). Ngokungafani nepayipi elinomshini, kukhonaakukho bungozi bokudilika kwe-liner, ukushwabana, noma ukugqwala kwe-cravice esibonakalayo.

Lokhu kuhlanganiswa kuyindinganiso yemboni yeukuqoqwa kwegesi emuncu ogwini,ukugeleza kwemigqa yokujova igesi ye-asidi (i-AGI),Imigqa yokudla yezitshalo zikaClaus, futhiimithombo yokulahla udoti enomfutho ophezulu.

8. Imibuzo Evame Ukubuzwa (Imibuzo Evame Ukubuzwa)

Umbuzo 1: Uyini umehluko phakathi kwe-X65 ne-X65MS?
A: I-X65MS iwukuguqulwa “kwenkonzo emuncu” kwe-X65. Inekhabhoni ephansi (≤0.10%), i-sulfur ephansi kakhulu (≤0.002%), ukulawulwa kobulukhuni okuqinile (≤248 HV), kanye nokuhlolwa kwe-SSC/HIC okuyimpoqo ngokwe-NACE MR0175. I-X65 ejwayelekile ayifanele i-H₂S emanzi.

Umbuzo 2: Kungani usebenzisa i-Incoloy 825 esikhundleni se-316L noma i-duplex ukuze uthole isevisi emuncu?
A: I-Incoloy 825 iqukethe i-nickel ephezulu (38-46%), enikeza ukumelana okuhle kakhulu ne-SCC kanye ne-SSC ebangelwa yi-chloride. Iphinde imelane nokunciphisa ama-acid (isb., i-HCl) kanye ne-elemental sulfur - izimo lapho i-316L kanye ne-duplex kuzohluleka khona. Ngenkonzo emuncu kakhulu (i-H₂S ephezulu + ama-chloride aphezulu + i-elemental S), i-Incoloy 825 ivame ukuba yi-CRA eyamukelekayo okungenani.

Umbuzo 3: Ingabe i-Incoloy 825 cladding ingashintshwa iye ngokwayo noma iye kwi-carbon steel?
A: Yebo. I-Incoloy 825 ingashintshwa yi-GTAW (TIG), GMAW (MIG), kanye ne-SMAW. Ukuze uhlanganise i-cladding ne-cladding, sebenzisa i-filler metal Alloy 82 / 82i (ERNiCr-3) noma i-Alloy 625 (ERNiCrMo-3). Ukuze uhlanganise i-cladding ne-carbon steel (isb., i-weld overlay), sebenzisa ungqimba oluphakathi lwe-Alloy 309L noma i-625 ukuze ugweme ukuncibilika nokuqhekeka.

Q4: Ingabe ukushintshwa komthungo we-longitudinal nakho kuyamelana nenkonzo emuncu?
A: Yebo. I-inner pass ihlanganiswe nge-Incoloy 625 filler (i-Ni ephezulu, i-Cr, i-Mo kune-825). Le weld overlay inikeza ukumelana nokugqwala okulinganayo noma okungcono kune-825 cladding. I-weld yonke ihlolwe yi-100% NDT futhi ubulukhuni buhlolwe.

Q5: Yiziphi izitifiketi ezinikezwayo zesevisi emuncu?
A: Sikhipha izitifiketi ze-EN 10204 Type 3.1/3.2 ezifaka phakathi ukuhlaziywa kokushisa kwensimbi engemuva, ubulukhuni, imibiko yokuhlola ye-SSC kanye ne-HIC (uma yenziwe), kanye nokuhlolwa kobulukhuni be-weld. Uma siceliwe, sinikeza incwadi yokuthobela imithetho ye-NACE MR0175.

Q6: Yisiphi isikhathi esijwayelekile sokuhola sepayipi elimbozwe nge-X65MS+Incoloy 825?
A: I-oda lokuqala: amasonto ayi-14-18 (kufaka phakathi ukuthengwa kwezinto zesevisi ezimuncu kanye neziqu). Ama-oda aphindaphindwayo: amasonto ayi-10-12. Ukuhlolwa komuntu wesithathu kungangeza amasonto ayi-1-2.

Umbuzo 7: Ingabe iWomic Steel ingahlinzeka ngepayipi elimboziwe le-Inconel 625 esikhundleni se-Incoloy 825?
A: Yebo. Ezimweni ezinzima kakhulu (izinga lokushisa eliphezulu, i-H₂S ephezulu, ama-chloride aphezulu), sinikeza ipayipi elimboziwe le-X65MS+Inconel 625 (UNS N06625). I-Inconel 625 inamandla aphezulu kanye nokumelana okungcono kwemigodi (PREN >45). Xhumana nathi ukuze uthole ishidi ledatha elihlukile.
