Ipayipi Lensimbi le-API 5L X42 LSAW: Amakhono Okukhiqiza kanye Nemininingwane Yomkhiqizo

Kungani i-Womic Steel isetshenziswa nge-X42 LSAW?

●Izinqubo ezintathu ezihambisanayo (i-JCOE, i-UOE, ipuleti eligoqiwe) ezimboza ububanzi obukhulu

●Amandla odonga olujiyile afinyelela ku-60mm (umthungo owodwa) noma u-80mm (umthungo ophindwe kabili) wokujova amanzi ngomfutho ophezulu kanye namapayipi amaningi

●Isikhungo se-PWHT sokuqeda ukucindezeleka odongeni olujiyile kanye namapayipi esevisi amuncu

●I-API 5L Monogram + CE + ukuhlolwa komuntu wesithathu (SGS, BV, TÜV, DNV)

●Ukushintsha okusheshayo (okuvamile ezinsukwini ezingu-30-50)

●Ubude obude obufika ku-24m bunciphisa ukushintshwa kwe-field girth ngo-30–40%

Imibuzo ejwayelekile ukubuzwa:

Q: Kufanele ngikhethe nini i-UOE esikhundleni se-JCOE ye-X42?
A: I-UOE inikeza ukuzungeza okungcono (±0.2% vs ±0.5% ye-JCOE) kanye nokucindezeleka okuphansi okusele, okwenza ithandeke kakhulu kumapayipi asogwini olujulile (ngaphansi kolwandle) kanye nensizakalo emuncu lapho ukuzinza kobukhulu ngaphansi kwengcindezi yangaphandle kubalulekile. I-JCOE ingabizi kakhulu kumaphrojekthi amaningi angaphandle kolwandle.

U: Ungakwazi yini ukwenza ipayipi elisindayo le-X42 elingaphezu kwama-50mm?
A: Yebo. Ukuze kube nobukhulu bodonga kusukela ku-50mm kuya ku-60mm, sisebenzisa umthungo owodwa wepuleti eligoqiwe one-PWHT. Kumthungo ophindwe kabili ongu-60mm. Lokhu kuvame ukusetshenziselwa imigqa yokujova amanzi ku-20-30 MPa noma kuma-penstock e-hydroelectric.

Q: Uyini umehluko phakathi kwe-PSL1 ne-PSL2 ye-X42?
A: I-PSL2 inemingcele eqinile ye-C, P, S, i-Charpy impact (27J @ 0°C), ubulukhuni obukhulu obungu-90 HRB, futhi idinga i-NDT eyengeziwe. Kuma-gas collection strings angase abe namazinga okushisa aphansi noma ama-H₂S traces, kunconywa i-PSL2.

U: Ingabe ninikeza isevisi emuncu i-X42?
A: Yebo. Sihlinzeka nge-X42 PSL2 ngokuhlolwa kwe-HIC (NACE TM0284) kanye ne-SSC (NACE TM0177). Izindlela zokwamukelwa ezijwayelekile: I-CLR ≤ 5%, i-CTR ≤ 1.5%, i-CSR ≤ 0.5%. Sihlinzeke ngensizakalo emuncu ye-X42 kumaphrojekthi aseMpumalanga Ephakathi naseNtshonalanga Afrika.

U: Uqinisekisa kanjani ikhwalithi yokushisela yamapayipi odonga olujiyile (40–60mm)?
A: Sisebenzisa i-multi-pass SAW enokulawula okunembile kokufaka ukushisa, ukuqapha izinga lokushisa phakathi kwe-interpass, kanye ne-100% automated UT ene-time-of-flight diffraction (TOFD) yokuhlola i-volumetric. I-PWHT isetshenziswa ukunciphisa ukucindezeleka okusele.

Inkomba Yephrojekthi – Inethiwekhi Yokuqoqa Igesi Yemvelo eNtshonalanga Afrika

Izwe:INigeria (isifunda saseNiger Delta)
Okujwayelekile kanye Nezinga:I-API 5L X42 PSL2 (isevisi emuncu, ihlolwe yi-HIC)
Ubukhulu kanye nobuningi:

OD 508mm (20″) × WIT 11.9mm – 12,000 amamitha (cishe amathani ayi-1,800) akhiqizwe yinqubo ye-JCOE

OD 762mm (30″) × UBUNZIMA 19.0mm – 3,500 amamitha (cishe amathani ayi-1,550) ekhiqizwe ngepuleti eligoqiwe elilodwa eline-PWHT
Imininingwane:Isembozo sangaphandle se-3LPE (ubukhulu obuphelele obungu-2.8mm), iziphetho ezigobile zingu-30° / 1.6mm ubuso bempande, i-hydrotest ku-8.5 MPa (ingcindezi yomklamo ingu-6.4 MPa). Umthelela we-Charpy ophoqelekile ku-0°C (ubuncane be-27J, kufinyelelwe ku-65–90J). I-HIC nge-NACE TM0284 Isixazululo A, amahora angu-96 – izindlela zokwamukela: I-CLR ≤ 5%, i-CTR ≤ 1.5%, i-CSR ≤ 0.5%.
Isicelo:Ukuqoqwa kwegesi yemvelo kusuka eziqongweni zemithombo eziyisithupha kuya esikhungweni sokucubungula esiphakathi endaweni enamaxhaphozi eNiger Delta. Ipayipi elisindayo elingamasentimitha angu-30 lasetshenziselwa i-header eyinhloko ewela ingxenye yexhaphozi engamakhilomitha angu-1.2, kanti amapayipi e-JCOE angamasentimitha angu-20 asebenza njengemigqa yamagatsha.

Izinselele Zobuchwepheshe Nezixazululo:

●Ukuwela ixhaphozi ngepayipi elisindayo lodonga– Amapayipi angu-30″ × 19.0mm (cishe angu-355 kg/m) kwadingeka afakwe exhaphozini elinobumba oluthambile kakhulu. Ama-lay barge ajwayelekile awakwazanga ukufinyelela endaweni. I-Womic Steel yanikeza amapayipi anezihlanganisi ezinde kakhulu (18m esikhundleni se-12m ejwayelekile) ukuze kuncishiswe inani lama-welds e-field girth ngo-33%, okunciphisa ukushisela endaweni ezimweni ezinzima. Siphinde sanikeza nezincomo ezinemininingwane zokuphakamisa nokuphatha okuhlanganisa nesikhala se-spreader beam.

●Ukuthobela imithetho yesevisi emuncu (i-H₂S ikhona)– Igesi ehambisanayo yayiqukethe kufika ku-30 ​​ppm H₂S. I-Womic yenze ukuhlolwa kwe-HIC kokubili kumapayipi epuleti angu-20″ JCOE kanye no-30″ rolled. Wonke amasampula adluliswe nge-CLR 0%, CTR 0%, CSR 0%. Kumapayipi angu-30″ (19mm WT), iklayenti lalidinga ubulukhuni obungaphansi kuka-85 HRB (obuqinile kune-API 5L's 90 HRB). I-Womic ifake ukushisa kwe-induction yendawo kumthungo we-weld ukuqinisekisa ubulukhuni obufanayo. Imiphumela: insimbi eyisisekelo 78–82 HRB, i-weld 80–85 HRB.

● Ukunamathela kwe-3LPE embozweni emswakama ophezulu– Ukufakwa kwamaxhaphozi kusho ukuthi amapayipi azocwiliswa emanzini amasonto ngaphambi kokugcwalisa kabusha. I-3LPE ejwayelekile ingaba nokuqhekeka kwe-cathodic uma umswakama wokusetshenziswa ungalawulwa. I-Womic ifake isembozo endaweni yokusebenzela elawulwa yisimo sezulu (ubuningi be-60% RH) futhi yenze ukutholwa kweholide okungu-100% ku-5kV. Amandla okuhlubuka ahlolwe ku-25°C anikeze >200 N/cm, okungaphezu kakhulu kwesidingo se-ISO 21809 esingu-100 N/cm.

●Ukuthunyelwa kwezinto endaweni ekude– Amapayipi athunyelwa esuka eShanghai aya eTin Can Island Port, eLagos, ayesethuthwa ngamaloli amakhilomitha angu-380 eya endaweni yaseNiger Delta. Izimo zomgwaqo zazimbi kakhulu futhi zinomkhawulo wesisindo. I-Womic yaklama uhlelo lokuthumela impahla isebenzisa ubude obujwayelekile obungu-12m wamapayipi angu-20″ (ahlanganisiwe) kanye namajoyinti angawodwa angu-18m wamapayipi angu-30″ kuma-trailer anezinqola zokuphelezela. Akukho monakalo noma ukugoba okwenziwe ngesikhathi sokuthutha.

● Umphumela:Inethiwekhi yokuqoqa igesi yaqaliswa ukusebenza kwikota yokuqala ka-2024. Wonke amathani angu-1,550 epayipi elingu-30″ kanye namathani angu-1,800 epayipi elingu-20″ adlule ekuhlolweni yi-SGS Nigeria. Iklayenti libike ukuthi akukho zinkinga zokushisela ngesikhathi sokushisela i-field girth, okubangelwa yi-bevel geometry ehambisanayo kanye nokulawulwa kwe-ovality (≤ 0.3% yamapayipi e-JCOE, ≤ 0.5% yamapayipi epuleti eligoqiwe). I-Womic Steel manje isifakwe ohlwini njengomhlinzeki ovunyelwe wokwandiswa kwamapayipi esikhathi esizayo eklayenti.
