Ipayipi Lensimbi Yensimbi Ye-X65+316L | Ipayipi Elinezintambo ze-CRA Elingabizi Kakhulu Lensizakalo ye-CO₂ – Insimbi Yensimbi

Incazelo emfushane:

Ipayipi Langaphandle (Insimbi Esekelayo):I-API 5L X65 PSL2 – amandla aphezulu, ukuqina okuhle kakhulu, okushiselwayo

Ulwelwesi Lwangaphakathi (i-CRA Cladding):316L (UNS S31603) – insimbi engagqwali e-austenitic enekhabhoni ephansi, emelana nokugqwala kwe-CO₂, futhi ikwazi ukushibilika kahle

Ububanzi Bosayizi:OD 219mm – 1219mm (8″ – 48″); Ubukhulu bodonga lwensimbi esekelayo 8mm – 30mm; Ubukhulu bokumboza 1.5mm – 3.0mm; Ubude obubodwa bufika ku-18m (kuyatholakala ama-24m ngokwezifiso)

Inqubo Yokukhiqiza:Ukubopha okushisayo + ukwakha i-JCOE – amandla okushefa esibonakalayo sesibopho sensimbi ≥200 MPa

Amazinga kanye Nezitifiketi:I-API SPEC 5LD (Ipayipi Lensimbi Elimboziwe le-CRA), DNV-OS-F101, NACE MR0175, ISO 15156. Isitifiketi Sokugaya EN 10204 Uhlobo 3.1. Ukuhlolwa komuntu wesithathu (SGS, BV, DNV, TÜV) kuyatholakala.

Izicelo:Amapayipi okuqoqa igesi yemvelo ogwini, imigqa yokufaka i-CO₂, izinhlelo zokufaka amanzi, imigqa yokugeleza kawoyela negesi ene-chloride ephansi, amapayipi axhumanisa indawo yokuhluza.

Insimbi YaseWomicinikeza ipayipi elimbozwe ngensimbi le-X65+316L – enye indlela engabizi kakhulu kune-alloys eqinile engu-316L noma ngaphezulu. Yakhelwe isevisi emnandi (i-CO₂ ngaphandle kwe-H₂S noma ama-chloride abalulekile). Isekelwa yimibhalo yekhwalithi ephelele kanye nesipiliyoni sokuthumela emhlabeni jikelele.

Amathegi Omkhiqizo

1. Ukubuka Konke – Kungani Ipayipi Elimboziwe le-X65+316L

Kumapayipi athutha igesi yemvelo equkethe i-carbon dioxide (CO₂) kodwa kunamanani amancane kuphela e-hydrogen sulfide (H₂S) kanye nama-chloride aphansi, insimbi yekhabhoni eqinile ibola ngokushesha, kuyilapho insimbi engagqwali eqinile engu-316L ivame ukuba ngaphezulu kakhulu futhi ibiza kakhulu.

Ipayipi elimbozwe ngensimbi ye-X65+316L eliboshwe ngensimbiinikeza indawo ephakathi nendawo efanelekile:

Isendlalelo sangaphandle se-X65inikeza amandla aphezulu (isivuno esincane esingu-450 MPa), ukuqina kokuphuka, kanye nokulawula ingcindezi - yilokho kanye ipayipi lomugqa we-API 5L X65 elaziwa ngakho.

Indwangu yangaphakathi engu-316Lithinta ngqo uketshezi, imelana nokugqwala kwe-CO₂, ukubola okuvamile, kanye nezimo ze-asidi encane.

Lezi zingqimba ezimbili zihlanganiswa unomphela yisibopho sensimbi (isibopho se-hot roll + i-JCOE forming). Akukho bungozi bokubhidlika kwe-liner, ukushwabana, noma ukuhlukana - ngokungafani nepayipi elifakwe ngomshini.

Le nhlanganisela isetshenziswa kabanzi ku-izinhlelo zokuqoqa igesi yemvelo emnandi,Amapayipi okubuyisa uwoyela athuthukisiwe e-CO₂ (EOR),imigqa yokujova amanzi, futhiukugeleza kukawoyela negesi okune-chloride ephansi.

4. Inqubo Yokukhiqiza - I-Hot Roll Bonding + JCOE

I-Womic Steel ikhiqiza ipayipi elimbozwe nge-X65+316L isebenzisa imboni eqinisekisiweukubopha okushisayo + ukwakha i-JCOEumzila:

Ukulungiswa kwendawo– Amapuleti e-X65 kanye ne-316L ayahlanzwa, agaywe, futhi ahlolwe.

Ukuhlanganiswa kwesitaki se-vacuum– Amapuleti amabili abekwe ndawonye ngesendlalelo esingu-316L sibheke ngaphakathi, sivalwe ngaphansi kwe-vacuum ukuze kukhishwe umoya-mpilo.

Ukugingqika okushisayo– Inqwaba ishiswa ku-1150-1250°C bese idlula emshinini wokugoqa. Ukunciphisa okuphezulu (5:1 kuya ku-10:1) kudala isibopho sensimbi ngokusabalala kwe-athomu.

Ukupholisa nokuhlola ipuleti– Ipuleti elimboziwe lipholile, futhi isibopho sihlolwe nge-100% ultrasonic ukuze kutholakale noma yikuphi ukuhlukana.

Ukwakhiwa kwe-JCOE– Ipuleti elimboziwe liyagaywa ngomphetho, bese lenziwa ipayipi elivulekile kusetshenziswa uchungechunge lwemishini yokucindezela i-JCO.

Ukushisela umthungo we-longitudinal– Umthungo ovulekile ushiselwe kusetshenziswa ukushisela kwe-arc okufakwe ohlangothini oluphindwe kabili (i-SAW) okune-filler engu-316L noma engu-309L ephasishini yangaphakathi kanye ne-carbon steel filler ephasishini yangaphandle.

Ukunweba (ongakukhetha)– Ukwandiswa kwemishini kuthuthukisa ukuzungeza futhi kunciphisa ukucindezeleka okwakhayo.

Ukwelashwa ngokushisa– Ukwelashwa kokushisa ngemva kokushiswa (i-PWHT) kusetshenziswa uma kudingeka ngokwencazelo yephrojekthi.

I-NDT kanye nokuhlolwa– Bheka iSigaba 5 ngezansi.

Qeda ukuqeda– Iziphetho ezigobile zinowoyela ovimbela ukugqwala kanye nezivalo zepulasitiki.

5. Ukulawulwa Kwekhwalithi Nokuhlolwa - Wonke Amapayipi Ahloliwe
