Tixraaca Mashruuca - Shabakadda Ururinta Gaaska Dabiiciga ah ee Galbeedka Afrika
Dalka:Nayjeeriya (gobolka Nayjeeriya Delta)
Heerka & Darajada:API 5L X42 PSL2 (adeeg dhanaan, HIC la tijaabiyay)
Cabbirka iyo Tirada:
OD 508mm (20″) × Miisaan 11.9mm – 12,000 mitir (qiyaastii 1,800 tan) oo ay soo saartay habka JCOE
OD 762mm (30″) × Miisaan 19.0mm – 3,500 mitir (qiyaastii 1,550 tan) oo lagu sameeyay tolmo saxan oo keliya oo leh PWHT
Tilmaamaha:Dahaarka 3LPE ee dibadda (dhumucda guud ee 2.8mm), dhammaadka godan 30° / 1.6mm wejiga xididka, baaritaanka hydrotest at 8.5 MPa (cadaadiska naqshadeynta 6.4 MPa).

Codsiga:Isu-ururinta gaaska dabiiciga ah laga bilaabo lix ceel oo ku yaal dhul qoyan oo ku yaal Niger Delta. Tuubada derbiga culus ee 30″ ayaa loo isticmaalay madaxa ugu weyn ee ka gudbaya qayb qoyan oo 1.2km ah, halka tuubooyinka JCOE ee 20″ ay u adeegeen xariiqyo laamo ah.
Caqabadaha Farsamada iyo Xalalka:
●Isgoyska qoyan oo leh tuubo derbi culus– Tuubooyinka 30″ × 19.0mm (qiyaastii 355 kg/m) waa in lagu rakibaa meel qoyan oo leh dhoobo aad u jilicsan. Doomaha caadiga ah ee la dhigo ma geli karaan goobta. Womic Steel waxay bixisay tuubooyin leh isku-xidhyo hal-dheer ah (18m halkii ay ka ahaan lahayd 12m caadiga ah) si loo yareeyo tirada alxanka goobta 33%, taasoo yaraynaysa alxanka goobta xaaladaha adag. Waxaan sidoo kale bixinnay talooyin faahfaahsan oo ku saabsan qaadista iyo maaraynta oo ay ku jiraan kala fogaanshaha alwaaxda.
●U hoggaansanaanta adeegga macaan (H₂S ayaa jirta)– Gaaska la xiriira wuxuu ka koobnaa ilaa 30 ppm H₂S. Womic waxay samaysay tijaabada HIC labada tuubo ee saxanka duuban ee 20″ JCOE iyo 30″. Dhammaan muunadaha waxay ku gudbeen CLR 0%, CTR 0%, CSR 0%. Tuubada 30″ (19mm WT), macmiilku wuxuu u baahday adkaansho ka hooseysa 85 HRB (ka adag API 5L's 90 HRB). Womic waxay ku marisay kuleyliyaha kicinta maxalliga ah tolmada alxanka si loo hubiyo adkaanta isku midka ah. Natiijooyinka: birta salka ah 78–82 HRB, alxanka 80–85 HRB.
● Ku dhegga dahaarka 3LPE ee qoyaanka sare leh– Rakibaadda qoyan waxay la macno tahay in tuubooyinka lagu dhex gelin doono biyo toddobaadyo ka hor inta aan dib loo buuxin. Heerka 3LPE wuxuu la kulmi karaa kala-goynta katooliga haddii qoyaanka la isticmaalo aan la xakamayn. Womic waxay dahaarka ku marisay aqoon-is-weydaarsi cimilo-xakamaysan (ugu badnaan 60% RH) waxayna samaysay 100% ogaanshaha fasaxa 5kV. Xoogga diirka ee lagu tijaabiyay 25°C wuxuu bixiyay > 200 N/cm, oo ka sarreeya shuruudaha ISO 21809 ee 100 N/cm.
●Saadka goobta fog– Tuubooyinka waxaa laga soo raray Shanghai ilaa Dekedda Jasiiradda Tin Can, Lagos, ka dibna waxaa loo raray 380km goobta Niger Delta. Xaaladaha waddooyinku way liitaan iyadoo culayska la xaddiday. Womic waxay naqshadaysay qorshe shixnad iyadoo adeegsanaysa dherer caadi ah oo ah 12m oo loogu talagalay tuubooyinka 20″ (la isku daray) iyo 18m oo isku-xidhka hal-hal ah oo loogu talagalay tuubooyinka 30″ ee ku yaal jiidayaasha fidsan ee leh gawaarida la socota.
