Me yasa Womic Steel don X42 LSAW?

●Tsaruka guda uku masu dacewa (JCOE, UOE, farantin da aka yi birgima) waɗanda suka shafi kewayon girma mai faɗi

●Ƙarfin bango mai kauri har zuwa 60mm (dinki ɗaya) ko 80mm (dinki biyu) don allurar ruwa mai ƙarfi da bututun manifold

●Tsarin PWHT don rage damuwa na bututun bango mai kauri da mai tsami

●API 5L Monogram + CE + dubawa na ɓangare na uku (SGS, BV, TÜV, DNV)

●Saurin dawowa (kwanaki 30-50 na yau da kullun)

●Tsawon tsayi har zuwa mita 24 yana rage yawan walda a cikin filin da kashi 30-40%

Tambayoyin da Ake Yawan Yi:

T: Yaushe ya kamata in zaɓi UOE maimakon JCOE don X42?
A: UOE tana ba da kyakkyawan tsari (±0.2% vs ±0.5% ga JCOE) da kuma ƙarancin matsin lamba, wanda hakan ya sa aka fi so ga bututun ruwa masu zurfi a teku (ƙasa da teku) da kuma sabis mai tsami inda kwanciyar hankali a ƙarƙashin matsin lamba na waje yake da matuƙar muhimmanci. JCOE ya fi araha ga yawancin ayyukan da ke cikin teku.

T: Za ku iya yin bututun bango mai nauyi na X42 fiye da 50mm?
A: Eh. Don kauri daga bango daga 50mm zuwa 60mm, muna amfani da farantin da aka naɗe guda ɗaya tare da PWHT. Don dinkin tsayi mai tsawon 60-80mm, mai tsawon tsayi biyu. Ana amfani da waɗannan galibi don layukan allurar ruwa a 20-30 MPa ko don penstocks na hydroelectric.

T: Menene bambanci tsakanin PSL1 da PSL2 don X42?
A: PSL2 yana da ƙaƙƙarfan iyaka na C, P, S, tasirin Charpy (27J @ 0°C), matsakaicin tauri 90 HRB, kuma yana buƙatar ƙarin NDT. Ga layukan tara iskar gas waɗanda za su iya fuskantar ƙarancin yanayin zafi ko alamun H₂S, ana ba da shawarar PSL2.

T: Shin kuna ba da sabis na tsami na X42?
A: Eh. Muna bayar da X42 PSL2 tare da gwajin HIC (NACE TM0284) da SSC (NACE TM0177). Ka'idojin karɓuwa na yau da kullun: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%. Mun samar da sabis na tsami X42 ga ayyukan Gabas ta Tsakiya da Yammacin Afirka.

T: Ta yaya za ku tabbatar da ingancin walda don bututun bango mai kauri (40-60mm)?
A: Muna amfani da na'urar SAW mai wucewa da yawa tare da daidaitaccen tsarin sarrafa shigar zafi, sa ido kan zafin jiki na interpass, da kuma UT mai sarrafa kansa 100% tare da lokacin tashi (TOFD) don gwajin volumetric. Ana amfani da PWHT don rage damuwa da ta rage.

Bayani dalla-dalla:Rufin 3LPE na waje (jimlar kauri 2.8mm), ƙarshen da aka yanke 30° / 1.6mm fuskar tushen, gwajin hydro a 8.5 MPa (matsin ƙira 6.4 MPa). Tasirin Charpy da ake buƙata a 0°C (minti 27J, an cimma 65–90J). HIC ga NACE TM0284 Magani A, awanni 96 – sharuɗɗan karɓa: CLR ≤ 5%, CTR ≤ 1.5%, CSR ≤ 0.5%.
Aikace-aikace:Tattara iskar gas daga rijiyoyi shida zuwa wani babban wurin sarrafa iskar gas a yankin dausayi na Niger Delta. An yi amfani da bututun bango mai kauri inci 30 don babban kan hanya da ke ketare wani yanki mai fadin kilomita 1.2, yayin da bututun JCOE mai inci 20 suka yi aiki a matsayin layukan reshe.

Kalubalen Fasaha da Magani:

●Ketarewar fadama tare da bututun bango mai nauyi– Dole ne a sanya bututun mai girman 30″ × 19.0mm (kimanin kilogiram 355/m2) a kan wani dausayi mai laushi mai laushi. Jiragen ruwa na yau da kullun ba za su iya shiga wurin ba. Womic Steel ta samar da bututu masu haɗin gwiwa guda ɗaya mai tsayi (mita 18 maimakon mita 12 na yau da kullun) don rage adadin walda a cikin filin da kashi 33%, wanda ke rage walda a wurin a cikin mawuyacin yanayi. Mun kuma bayar da cikakkun shawarwari dagawa da sarrafawa, gami da tazara tsakanin katako mai shimfiɗawa.

●Tsarin bin ƙa'idodin sabis mai kyau (H₂S yana nan)– Iskar gas ɗin da ke da alaƙa ta ƙunshi har zuwa 30 ppm H₂S. Womic ta yi gwajin HIC a kan bututun faranti na 20″ JCOE da 30″. Duk samfuran sun wuce da CLR 0%, CTR 0%, CSR 0%. Ga bututun 30″ (19mm WT), abokin ciniki yana buƙatar tauri ƙasa da 85 HRB (ya fi tsauri fiye da API 5L's 90 HRB). Womic ta yi amfani da dumamawar induction na gida a kan dinkin walda don tabbatar da tauri iri ɗaya. Sakamako: ƙarfe mai tushe 78–82 HRB, walda 80–85 HRB.

● Mannewa mai shafi 3LPE a cikin matsanancin zafi– Shigar da bututun ruwa a cikin ruwa yana nufin a nutsar da bututun a cikin ruwa na tsawon makonni kafin a cika shi. Na'urar 3LPE ta yau da kullun na iya fuskantar narkar da cathodic idan ba a sarrafa danshi a aikace ba. An yi amfani da murfin a cikin wani wurin aiki mai kula da yanayi (mafi girman 60% RH) kuma an yi gwajin hutu 100% a 5kV. Ƙarfin barewa da aka gwada a 25°C ya ba da > 200 N/cm, sama da buƙatar ISO 21809 na 100 N/cm.

●Logistics zuwa wurin nesa– An jigilar bututu daga Shanghai zuwa tashar jiragen ruwa ta Tin Can Island, Lagos, sannan aka yi jigilar manyan motoci tsawon kilomita 380 zuwa yankin Niger Delta. Yanayin hanya bai yi kyau ba tare da ƙayyadadden nauyi ba. Womic ta tsara tsarin jigilar kaya ta amfani da tsayin mita 12 na yau da kullun don bututun 20" (wanda aka haɗa) da kuma haɗin gwiwa guda ɗaya na mita 18 don bututun 30" akan tireloli masu faɗi tare da motocin rakiya. Babu lalacewar rufi ko lanƙwasa da aka samu yayin jigilar.

● Sakamako:An ƙaddamar da aikin hanyar tattara iskar gas a kwata na ɗaya na shekarar 2024. Duk bututun tan 1,550 na inci 30 da tan 1,800 na bututun tan 20" sun wuce dubawa ta ɓangare na uku daga SGS Nigeria. Abokin ciniki ya ba da rahoton babu lahani na walda yayin walda a lokacin walda, wanda aka danganta da daidaiton yanayin bevel da kuma ikon sarrafa ovality (≤ 0.3% ga bututun JCOE, ≤ 0.5% ga bututun faranti da aka birgima). Yanzu Womic Steel an jera shi a matsayin mai samar da kayayyaki da aka amince da su don faɗaɗa bututun mai na abokin ciniki nan gaba.
