Iimeko zeSicelo soMbhobho wentsimbi: Ngaphandle konxweme ukuya kunkcenkceshelo

Iimeko zeSicelo - Umbhobho we-Octal

Ukusuka kwimibhobho yamanzi anzulu ukuya kwimibhobho ye-Arctic, iigridi zamanzi amakhulu ukuya kwimigca emikhulu yasentlango, imihlaba ebanzi yeefama ukuya kwiindawo zokunqumla amahlathi emvula - i-Octal Pipe inikezela ngomqolo wentsimbi{1} ephezulu yokusebenza kwamandla ehlabathi, amanzi kunye neziseko zophuhliso.

Amaqonga e-Oli kunye neGesi engaselunxwemeni

Imibhobho yamanzi anzulu, i-FPSO topsides kunye neebhatyi ezisisigxina zifuna imibhobho ehlala ishukuma rhoqo, isitshizi setyuwa kunye noxinzelelo olungaphaya kwe-15,000 psi. Enkulu-i-diameter LSAW X65–X70 ene-3LPE okanye i-FBE + yokwambathisa ubunzima bekhonkrithi ngumgangatho woshishino apha. Uqhagamshelo lwePremium (VAM TOP, TENARIS BLUE) iqinisekisa ukusebenza okuqinile kwerhasi{9}}kwindawo yokunyuka kunye nokuthumela ngaphandle ukusuka kuLwandle lwaseMantla ukuya eBrazil{10}}phambi kwemimandla yetyuwa.

I-Subsea Flowlines & Iqhina{0}}Ngasemva

Kubunzulu obugqithisa kwi-2,500 m, i-SSAW X60–X70 ene-5-i-layer sintered epoxy okanye ukugquma okumanzi kunika eyona bhalansi yeendleko, ukuguquguquka kunye nokhuseleko lomhlwa. Uyilo lomthungo we-helical usasaza uxinzelelo lokugoba ngokulinganayo ngexesha le-reel{7}}i-lay okanye i-J{10}}yofakelo lofakelo, ngelixa ubukhulu be-CWC obuyi-50-120 mm buqinisekisa uzinzo kumzantsi kwimisinga enamandla.

Ukunqumla{{0}ilizwe elikrwada, imveliso kunye{1}}nemizila yerhasi yendalo ixhomekeke kwi-API 5L X52–X80 LSAW ukugquma amakhulu eekhilomitha ngezikhululo zokumpompa ezingephi{5}}Ukwaleka kwe-LPP kunye nokhuseleko lwe-cathodic luzisa 50+ ubomi boyilo lweminyaka kwiintlango, kwi-permafrost kunye nomhlaba wasefama. Ukunyamezelwa okuqinileyo kwe-OD kunye -amanqaku esivuno aphezulu agcina ubukhulu bodonga - kwaye ke ubunzima kunye neendleko - ubuncinci.

Imigxobhozo, iNgxobhozo kunye nokunqumla kwamahlathi

Umhlaba othambileyo, odlamkileyo kakhulu kwimimandla efana ne-Amazon Basin, i-Niger Delta, kunye ne-Louisiana bayous ifuna ukugquma ubunzima bekhonkrithi enzima (CWC) kwi-SSAW okanye imibhobho ye-LSAW ukuze kuzuzwe ukushukuma okungalunganga kunye nokuthintela ukudada ngexesha lezikhukula zonyaka. Iindonga ezityebileyo ezidityaniswe ne-fusion{1}}ebond epoxy (FBE) okanye i-3LPE yokwambathisa ngokufanelekileyo ixhathise i-H₂S, i-CO₂, kunye ne-organic acids efumaneka kwiindawo ezimanzi.

Uthungelwano lwaManzi eziDolophini noGutyulo

Ngaphantsi kwezitrato zedolophu,AWWA C200 spiral welded imibhobhokwayeImibhobho ye-ASTM A53 ERWzezona zikhethwayo kwimibhobho yamanzi aselwayo, iiringi zokukhusela umlilo, kunye neendawo zokusebenzisa amanzi amdaka.

Ngaphakathiisamente -ingubo yodakaokanyeukutya -ibakala epoxy ukutyabekaithobela ngokupheleleyoNSF/ANSI 61kukhuseleko lwamanzi-okusela, ngelixa ungaphandlei-polyurethane, i-polyethylene eyongeziweyo, okanyeanti{0}}ukuvalwa kwe tapeinikeza-ukhuseleko lwexesha elide kumhlaba ondlongondlongo wedolophu, amanzi aphantsi komhlaba, kunye nokulahleka{1} kwangoku okuxhaphakileyo kwiindawo zedolophu.

Unkcenkceshelo lwasemaPhandleni nokwezoLimo

-Iziko elikhulu-zepivot kunye neenkqubo zokuthontsiza zisebenzisa igalvanized okanye ipolyethylene{2}}coated SSAW (12–48 in) ukuhambisa izigidi zeegaloni yonke imihla ngokuvuza okuphantse ukuba ngunothi. Ikhaphukhaphu ngemitha nganye kunye nobude obuyi-12–18 m ubude bunciphisa amajoyinti kunye nexesha lofakelo kuwo wonke amafama avulekileyo.
