Goobaha Shidaalka & Gaaska ee Badda

Riigagga biyaha qoto dheer, geesaha sare ee FPSO iyo jaakadaha go'an ayaa dalbanaya tubooyinka ka badbaada dhaqdhaqaaqa hirarka joogtada ah, buufin milix ah iyo cadaadis ka badan 15,000 psi. Dhexroor weyn -LSAW X65–X70 oo leh 3LPE ama FBE + daahan miisaanka la taaban karo waa heerka warshadaha halkan. Xidhiidhada qiimaha leh (VAM TOP, TENARIS BLUE) waxay xaqiijiyaan gaaska{9}}waxqabadka adag ee kiciye iyo khadadka dhoofinta ee Badda Waqooyi ilaa Brazil ka hor{10} beerihii cusbada.

Qulqulka badda hoosteeda iyo xidhidh -Garab

Moolka dheer ee ka sarreeya 2,500 m, SSAW X60–X70 oo leh 5{6}}lakabka epoxy-ka lakabka ah ama dahaarka qoyan wuxuu bixiyaa dheelitirka ugu fiican ee qiimaha, dabacsanaanta iyo ilaalinta daxalka. Naqshadeynta tolnimada Helical waxay u qaybisaa qaloocinta si siman inta lagu jiro gariirada{7}}lay ama J{10} rakibida, halka dhumucda CWC ee 50-120 mm ay dammaanad qaadayso xasiloonida hoose ee qulqulka xooggan.

Iskutallaab -Ceyriin, badeecada iyo dabiciga - khadadka jirridda gaaska waxay ku tiirsan yihiin API 5L X52–X80 LSAW si ay u daboosho boqolaal kiiloo mitir oo leh saldhigyada bamka ee ugu yar . 3Daahanka LPP iyo ilaalinta cathodic waxay 50+ nashqadeynta sanadka gaarsiisaa lamadegaanka, barmafrost iyo dhul beereed. Dulqaadyada adag ee OD iyo sare -darajooyinka wax-soo-saarka ayaa ilaaliya dhumucda gidaarka - oo sidaas darteed miisaanka iyo qiimaha - ugu yaraan.

Isgoysyada Swamp, Marsh & Kaynta Roobka

Ciidda jilicsan, aadka u kacsan ee gobollada sida Amazon Basin, Niger Delta, iyo Louisiana bayous waxay u baahan yihiin daahan culeys culus oo la taaban karo (CWC) ee tuubooyinka SSAW ama LSAW si loo gaaro guux taban oo looga hortago sabbeynta inta lagu jiro fatahaadaha xilliyeed. Darbiyada dhuuban ee ay weheliyaan fiyuuska{1} epoxy bonded (FBE) ama 3LPE dahaarka ayaa si wax ku ool ah isaga caabiya H₂S, CO₂, iyo asiidhyada organic sida caadiga ah laga helo deegaanka qoyan.

Waraabka Miyiga & Beeraha

Xarun weyn -xarunta cabirka -Nidaamka pivot iyo dhibicda waxay isticmaalaan galvanized ama polyethylene{2}}dahaaran SSAW (12-48 in) si ay u guurto malaayiin gallon maalin kasta iyadoo ku dhawaad eber ka daadan. Miisaanka fudud ee mitirkiiba iyo dhererka 12-18 m waxay yareeyaan kala-goysyada iyo wakhtiga rakibida dhul-beereed furan.
