Umuyoboro w'icyuma wa API 5L X42 LSAW: Ubushobozi bwo gukora n'ibisobanuro by'ibicuruzwa

Kuki Womic Steel ya X42 LSAW?

●Uburyo butatu bwuzuzanya (JCOE, UOE, plaque izungurutse) bukubiyemo urwego runini rw'ibipimo

●Ubushobozi bw'urukuta bunini bugera kuri mm 60 (umugozi umwe) cyangwa mm 80 (umugozi ubiri) bwo gutera amazi mu muvuduko mwinshi no gukoresha imiyoboro myinshi

●Ikigo cya PWHT cyo kugabanya stress ku rukuta rurerure n'imiyoboro ishyushye

●API 5L Monogram + CE + igenzura ry’umuntu wa gatatu (SGS, BV, TÜV, DNV)

●Guhindura ibintu vuba (ibisanzwe mu minsi 30–50)

●Uburebure bugera kuri metero 24 bugabanya ubugari bw'imigozi ku kigero cya 30–40%.

Ibibazo Bikunze Kubazwa:

Q: Ni ryari nkwiye guhitamo UOE aho guhitamo JCOE kuri X42?
A: UOE itanga uburebure bwiza (± 0.2% ugereranije na ± 0.5% kuri JCOE) kandi igagabanya ubukana bw'ibisigazwa, bigatuma ikundwa cyane ku miyoboro yo mu mazi y'ubujyakuzimu (yo munsi y'inyanja) na serivisi mbi aho ubusugire bw'ibipimo mu gihe cy'igitutu cyo hanze ari ingenzi cyane. JCOE ihendutse cyane ku mishinga myinshi yo mu mazi.

Q: Ese ushobora gukora umuyoboro munini wa X42 uremereye urenze 50mm?
A: Yego. Ku bugari bw'urukuta kuva kuri mm 50 kugeza kuri mm 60, dukoresha umugozi umwe uzungurutse hamwe na PWHT. Ku mugozi ufite uburebure bwa mm 60–80, ufite uburebure bubiri. Ubusanzwe ukoreshwa mu gushora amazi kuri 20–30 MPa cyangwa ku byuma bitanga amashanyarazi.

Q: Ni irihe tandukaniro riri hagati ya PSL1 na PSL2 kuri X42?
A: PSL2 ifite imipaka ya C, P, S ikomeye, ikoreshwa rya Charpy (27J @ 0°C), ubukana ntarengwa bwa 90 HRB, kandi ikenera NDT nyinshi. Ku mirongo iteranya gazi ishobora kugira ubushyuhe buke cyangwa H₂S, PSL2 irasabwa.

Q: Ese mutanga serivisi nziza X42?
A: Yego. Dutanga X42 PSL2 hamwe n'ikizamini cya HIC (NACE TM0284) na SSC (NACE TM0177). Ibipimo bisanzwe byo kwemerwa: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. Twatanze serivisi mbi ya X42 ku mishinga yo mu Burasirazuba bwo Hagati no muri Afurika y'Iburengerazuba.

Q: Ni gute wakwizeza ko imiyoboro y'inkuta nini (40–60mm) ifite ubuziranenge bwo gusudira?
A: Dukoresha uburyo bwa multi-pass SAW bufite uburyo bwo kugenzura neza ubushyuhe, kugenzura ubushyuhe hagati y’ibice, na 100% automatique UT ifite igihe cyo gusohora indege (TOFD) mu gusuzuma ubwinshi bw’amazi. PWHT ikoreshwa mu kugabanya imihangayiko isigaye.

Icyitonderwa cy'umushinga – Urugaga rw'ikusanyirizo rya gaze karemano muri Afurika y'Iburengerazuba

Igihugu:Nijeriya (akarere ka Nijeriya Delta)
Igipimo n'Icyiciro:API 5L X42 PSL2 (serivisi idafite akamaro, yapimwe na HIC)
Ingano n'ingano:

OD 508mm (20″) × Ubwinshi 11.9mm – metero 12.000 (hafi toni 1.800) yakozwe na JCOE process

OD 762mm (30″) × Ubwinshi 19.0mm – metero 3.500 (hafi toni 1.550) ikorwa n'umugozi umwe wa plaque izungurutswe hamwe na PWHT
Ibisobanuro:Ingufu zo hanze za 3LPE (ubugari bwose bwa 2.8mm), impera zikozweho 30° / 1.6mm, ikizamini cya hydrotest kuri 8.5 MPa (igipimo cy'umuvuduko wa 6.4 MPa). Ingufu za Charpy zisabwa kuri 0°C (ubugari bwa 27J, zageze kuri 65–90J). HIC kuri NACE TM0284 Igisubizo A, amasaha 96 – ibipimo byo kwemerwa: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%.
Porogaramu:Gukusanya gaze karemano kuva ku masoko atandatu kugera ku ruganda rutunganya amazi ruri mu gishanga cya Niger Delta. Umuyoboro munini wa santimetero 30 wakoreshejwe mu gice cy’igishanga cya kilometero 1.2, mu gihe imiyoboro ya JCOE ya santimetero 20 yari imiyoboro y’amashami.

Ibibazo bya tekiniki n'ibisubizo:

●Kwambuka mu gishanga gifite umuyoboro uremereye wo ku nkuta– Imiyoboro ya 30″ × 19.0mm (hafi 355 kg/m) yagombaga gushyirwa ku gishanga gifite ibumba ryoroshye cyane. Udukoresho dusanzwe twometseho ntitwashoboraga kugera aho twagombaga gukorerwa. Womic Steel yatanze imiyoboro ifite imiyoboro miremire cyane (18m aho kuba 12m isanzwe) kugira ngo igabanye umubare w’imiyoboro yo gusudiraho 33%, bigabanya gusudira aho hantu mu bihe bigoye. Twanatanze inama zirambuye zo kuzamura no gufata ibintu harimo n’intera y’imiyoboro yo gukwirakwiza.

●Gukurikiza amategeko agenga serivisi (H₂S irahari)– Gazi ijyanye nayo yari irimo ingano ya 30 ppm H₂S. Womic yakoze isuzuma rya HIC ku miyoboro ya plate ya 20″ JCOE na 30″ rolled. Ingero zose zatanzwe hakoreshejwe CLR 0%, CTR 0%, CSR 0%. Ku muyoboro wa 30″ (19mm WT), umukiriya yasabaga ubukana buri munsi ya 85 HRB (bukomeye kurusha API 5L's 90 HRB). Womic yashyizeho ubushyuhe bwo mu gace k'imashini ku mugozi wo gusuka kugira ngo irebe ko bungana. Ibisubizo: icyuma cyo hasi 78–82 HRB, gusuka 80–85 HRB.

● Gufatana kwa 3LPE mu gihe cy'ubushuhe bwinshi– Gushyiramo ibishanga byasobanuraga ko imiyoboro yakwinjizwa mu mazi mu gihe cy'ibyumweru mbere yo kongera kuzura. 3LPE isanzwe ishobora kwangirika mu mazi iyo ubushuhe bukoreshejwe budagenzuwe. Womic yashyize irangi mu icupa rigenzurwa n'ikirere (ntarengwa 60% RH) kandi yagenzuwe 100% ku gipimo cy'iminsi mikuru kuri 5kV. Ubushyuhe bwapimwe kuri 25°C bwatanze > 200 N/cm, hejuru cyane y'igipimo cya ISO 21809 cya 100 N/cm.

●Ibikoresho bijya ahantu ha kure– Imiyoboro yoherejwe iva i Shanghai ijya Tin Can Island Port, Lagos, hanyuma itwarwa n’amakamyo ibirometero 380 kugera aho Niger Delta iherereye. Imihanda yari mibi cyane kandi hari uburemere buke. Womic yashushanyije gahunda yo kohereza ibicuruzwa ikoresheje uburebure bwa metero 12 ku miyoboro ya santimetero 20 (ifatanye) na metero 18 ku miyoboro ya santimetero 30 ku modoka zitwara imizigo zifite imodoka ziherekeza imizigo. Nta cyangiritse cyangwa ngo gipfundike cyabayeho mu gihe cyo gutwara imizigo.

● Ibisubizo:Umuyoboro wo gukusanya gazi watangiye gukoreshwa mu gihembwe cya mbere cya 2024. Toni 1.550 zose z'imiyoboro ya santimetero 30 n'toni 1.800 z'imiyoboro ya santimetero 20 zagenzuwe n'ikigo cya SGS muri Nijeriya. Umukiriya yavuze ko nta nenge na imwe y'ubusoderi yakozwe mu gihe cyo gusudira mu butaka, bitewe n'imiterere ya bevel hamwe n'igenzura ry'urukiramende (≤ 0.3% ku miyoboro ya JCOE, ≤ 0.5% ku miyoboro ya plaque izungurutse). Womic Steel ubu iri ku rutonde rw'abatanga serivisi zemewe zo kwagura imiyoboro y'umukiriya mu gihe kizaza.
