Tambayoyin da Ake Yawan Yi:

T: Menene babban bambanci tsakanin X52 PSL1 da PSL2 don bututun LSAW?
A: PSL2 yana da ƙaƙƙarfan iyakokin sinadarai (ƙasa C, P, S), taurin tasirin Charpy (mafi ƙarancin 27J @ 0°C ko ƙasa), matsakaicin iyakokin tauri (90 HRB), kuma yana buƙatar ƙarin NDT mai ƙarfi (100% UT idan aka kwatanta da UT mai tabo don PSL1). Ga bututun iskar gas mai matsin lamba, sabis na teku, ko mai tsami, PSL2 ya zama dole. Ga layukan ruwa ko mai mai ƙarancin matsin lamba, PSL1 abin karɓa ne kuma ya fi araha.

T: Za ku iya samar da gwajin tasirin zafi mai ƙarancin zafi na X52 ga ayyukan arctic?
A: Eh. Muna samar da X52 PSL2 tare da gwajin tasirin Charpy a -46°C (min 27J) da DWTT a -20°C (min 85% yankin yanke). Mun samar da matakin arctic X52 ga ayyukan Kanada da Rasha. Da fatan za a ƙayyade zafin gwajin da ake buƙata da kuzari lokacin da ake tambaya.

T: Menene matsakaicin kauri na bango da za ku iya samarwa don X52 LSAW?
A: Tsarin JCOE matsakaicin 50.8mm, Tsarin UOE matsakaicin 40mm, Farantin da aka naɗe guda ɗaya har zuwa 70mm, Farantin da aka naɗe biyu har zuwa 80mm. Don kauri bango fiye da 50.8mm, PWHT ya zama dole. Kwanan nan mun samar da X52 1,600mm OD × 70mm WT don aikin allurar ruwa mai ƙarfi a Oman.

T: Ta yaya ake sarrafa taurin kai don hidimar X52 mai tsami?
A: Muna sarrafa sinadaran da ke cikin sinadarai (CEV ≤ 0.40% don amfani da tsami, ƙasa da 0.43%) na yau da kullun, muna sarrafa shigar da zafi yayin walda SAW (≤ 3.0 kJ/mm), kuma muna amfani da PWHT don kauri bango ≥ 20mm. Taurin bayan PWHT yawanci shine 78-85 HRB don ƙarfe na tushe da 82-88 HRB don walda. Muna ba da cikakkun takaddun tauri.

T: Shin kuna ba da duba bututun X52 LSAW na ɓangare na uku?
A: Eh. Muna aiki da SGS, BV, TÜV, DNV, ABS, da LR. Ana iya yin binciken a masana'antarmu yayin samarwa, wanda wakilin abokin ciniki ko hukumar ɓangare na uku suka shaida. Muna bayar da takaddun shaida na EN 10204 Type 3.2 idan an buƙata.

T: Menene lokacin jagora na yau da kullun don bututun X52 LSAW?
A: Lokacin isar da sako na yau da kullun: kwanaki 30-45 don PSL1, kwanaki 45-60 don PSL2 tare da gwajin sabis mai tsami. Umarnin gaggawa (kwanaki 20-30) yana yiwuwa ga ƙananan adadi (tan 10,000), lokacin isar da sako na iya tsawaita zuwa kwanaki 75 dangane da samuwar farantin.

T: Za ku iya samar da X52 tare da murfin 3LPE da murfin siminti mai nauyin siminti don bututun mai na ƙasashen waje?
A: Eh. Muna samar da rufin 3LPE bisa ga ISO 21809 (jimillar kauri 2.5-3.5mm) kuma muna iya daidaita rufin siminti (kauri 40-120mm, yawa 2,400-3,050 kg/m³) a farfajiyar rufin abokin hulɗarmu da ke Tianjin. Mun samar da rufin X52 na teku ga ayyukan Vietnam, Indonesia, da Gabas ta Tsakiya.

Aikace-aikace:Bututun fitar da mai daga Uganda (yankin Hoima) zuwa tashar jiragen ruwa ta Tanga ta Tanzaniya a Tekun Indiya. Jimillar tsawon bututun mai ya kai kilomita 1,443. Womic Steel ta samar da kilomita 68.5 na jimillar, ciki har da sassan da ke ratsa yankunan namun daji masu mahimmanci da kuma manyan hanyoyin ketare koguna.

Kalubalen Fasaha da Magani:

● Bin ƙa'idodin aiki mai tsami don ɗanyen mai tare da H₂S– Danyen mai na Uganda ya ƙunshi H₂S da aka narkar har zuwa ppm 15 tare da ruwa. An buƙaci gwajin HIC da SSC mai ƙarfi. Womic ta yi gwajin cancanta a filayen samarwa 15. Duk sun wuce da CLR 0%, CTR 0%, CSR 0% don HIC. Gwajin SSC (NACE TM0177, 720h) bai nuna fashewar saman ba. Mun cimma wannan ta hanyar kiyaye CEV ≤ 0.38% (ƙasa da iyakar PSL2 na 0.43%) da kuma amfani da PWHT ga duk bututun da suka wuce 12.7mm WT, duk da cewa API 5L ba ya tilasta PWHT ƙasa da 25.4mm. Mai duba abokin ciniki (SGS) ya shaida duk gwajin.

● Takaddun muhalli na yankin namun daji– Bututun yana ratsa ta cikin wuraren ajiyar dabbobi guda biyu na ƙasa. Lalacewar rufi yayin shigarwa zai yi wuya a gyara saboda ƙarancin damar shiga. Womic ta yi amfani da wani Layer na polyethylene na hadaya (ƙarin 0.5mm akan 3LPE na yau da kullun) a matsayin murfin da ke jure gogewa.

● Matsewar kogi da ke buƙatar katangar da ta fi kauri– Manyan hanyoyin ketare kogi guda biyar (magudanar ruwa ta Nilu) suna buƙatar WT 15.9mm maimakon 12.7mm don ƙarin juriya ga rugujewa da lanƙwasa yayin shigar da bututun bango mai kauri, mun yi amfani da tsarin UOE don ingantaccen zagaye (±0.2% OD) don tabbatar da ingantaccen walda a cikin sassan ketarewa. An auna ovality a 0.15-0.18%, ƙasa da iyakar 0.5%.

● Tsarin zirga-zirgar jiragen sama mai nisa– An jigilar bututu daga Shanghai zuwa tashar jiragen ruwa ta Dar es Salaam (Tanzania), sannan aka yi jigilar manyan motoci kilomita 1,200 zuwa bututun Uganda. Yanayin hanyoyi a yammacin Tanzania ya haɗa da sassan da ba a shimfida ba. Womic ta tsara wani tsari na musamman na jigilar kaya: tsawon mita 12 kawai (babu haɗin gwiwa miliyan 18 ga sashin Uganda) don dacewa da manyan motocin da aka shimfiɗa a kan bene na yau da kullun. Kowace bututu an ɗaure ta da majajjawa masu laushi daban-daban. Mun ba da zane-zanen lodi da horo ga kamfanin jigilar kaya na gida. Babu bututun da ya lalace yayin jigilar kilomita 1,200 a kan ƙasa.

● Takardu masu tsauri da kuma bin diddiginsu– Aikin ya buƙaci takaddun shaida na EN 10204 Type 3.2 ga kowace lambar zafi, tare da cikakken bin diddigin daga faranti zuwa bututun da aka gama. Womic ta naɗa wani mai kula da takardu na musamman wanda ke bin diddigin dukkan bututun kilomita 68.5. An buga wa kowane bututun tambari da lambar zafi, lambar bututu, da kuma daidaitawar GPS na samarwa. Ƙungiyar QA ta abokin ciniki ta duba wurin aikinmu sau biyu a lokacin samarwa; duka binciken sun wuce ba tare da bin ka'ida ba.

Sakamako:An shirya kammala bututun mai na Gabashin Afirka (EACOP) a cikin kwata na biyu na 2025. An isar da tan 13,000 na bututun X52 PSL2 na Womic Steel tsawon watanni 8 (jigilar farko a watan Oktoba 2023, jigilar karshe a watan Mayu 2024). Duk bututun sun wuce binciken ɓangare na uku daga SGS Tanzania. Abokin ciniki (ƙungiyar kamfanonin mai na ƙasashen duniya) ya bayar da wasiƙar yabo kan kula da inganci na Womic da kuma isar da shi akan lokaci. Womic yanzu ta zama mai samar da kayayyaki da suka cancanta don faɗaɗa bututun mai a nan gaba a yankin.
