Submarine pipelines tau qhuas tias yog lub neej ntawm kev loj hlob ntawm ntug dej hiav txwv thiab roj av, ua haujlwm zoo tshaj plaws thiab kev nyab xeeb tshaj plaws ntawm kev thauj mus los rau cov khoom siv roj marine thiab roj. Txawm li cas los xij, vim qhov kev ua haujlwm hnyav ntawm cov kav dej, qhov tsis xws luag, kev pabcuam ntev mus ntev, thiab muaj ntau yam tsis paub meej, corrosion, tsis xws luag, thiab kev puas tsuaj rau cov kav dej yog yam tsis muaj kev cuam tshuam. Lub hav zoov ntawm cov teeb meem no ua rau muaj kev phom sij rau kev nyab xeeb ntawm cov kav dej. Yog tias tsis kho thiab kho tam sim ntawd, kev puas tsuaj loj thiab xwm txheej yuav tshwm sim.
Tam sim no, kev kho cov kav dej thiab kev txhawb nqa feem ntau koom nrog txoj hauv kev xws li hloov cov yeeb nkab, vuam, clamping, thiab cov khoom sib xyaw. Cov pa roj carbon fiber ntau cov cuab yeej siv cuab yeej cuab tam, ib hom kev kho cov khoom siv sib xyaw, suav nrog kev siv cov pa roj carbon fiber ntau nrog cov resin los tsim cov txheej txheem ntawm cov raj xa dej, sib koom cov khoom thauj los ntawm cov raj xa dej, txo cov kev ntxhov siab thiab kev nyuaj siab ntawm phab ntsa pipeline, thiab yog li ntawd. kho los yog txhim kho lub siab-kev muaj peev xwm ntawm cov kav dej. Tam sim no nws yog qhov zoo tshaj plaws kho thiab txhawb nqa technology.
Cov pa roj carbon fiber ntau cov ntawv kho ntawm cov kav dej steel yog kev kho cov txheej txheem thiab cov cuab yeej txhawb nqa uas tau tshwm sim hauv xyoo 1990, muaj txiaj ntsig zoo thoob ntiaj teb. Nws tau dav siv nyob rau hauv tshuaj nroj tsuag, pej xeem vaj tse, txuas hniav, thiab lwm yam tshwj xeeb cov qauv, ua ib tug qauv nyob rau hauv txoj kev loj hlob ntawm steel pipeline qauv kho thiab ntxiv dag zog. Piv nrog rau cov txheej txheem kho hlau tsoos, qhov kho tshuab no muaj tsib qhov zoo sib xws: siab tensile zog thiab modulus, zoo heev creep kuj; muaj peev xwm tsim muaj zog, tso cai rau cov txheej txheem tsim khoom raws li kev siv thiab kev thauj khoom; ntau yam txheej txheem molding rau kev kho thiab txhawb cov cheeb tsam loj lossis cov txheej txheem nyuaj xws li khoov kav, tees, reducers, thiab lwm yam.; yooj yim thiab ceev kev tsim kho, kho lub sij hawm luv luv thiab ntxiv dag zog, tus nqi qis; thiab qhov zoo xws li tsis muaj vuam lossis kev ua haujlwm kub, kev kho siab-cov kabmob, thiab kev pheej hmoo tsawg.
Hauv kaum xyoo dhau los, carbon fiber ntau cov khoom siv kho tshuab tau siv ntau ntxiv hauv kev kho cov corroded hnyav, mechanically puas, tawg, thiab cov kav dej. Cov kws tshawb fawb hauv tsev tau tshawb fawb ntau yam hauv cheeb tsam no. Cov pa roj carbon fiber ntau cov khoom siv txhawb nqa thiab kho qhov system muaj cov ntaub ntawv carbon fiber, impregnation nplaum, primer, thiab tshwj xeeb kho tus neeg saib xyuas, txhua tus ua haujlwm ua ke ntawm cov kav dej. Thaum siv cov pa roj carbon fiber ntau cov khoom siv kho kom zoo rau kev kho qhov tsis xws luag, qhov tsis xws luag yog thawj zaug sau cov khoom siv, thiab tom qab ntawd cov pa roj carbon fiber qhwv nrog epoxy nplaum, tsim cov khoom sib xyaw ua ke rau sab nraud ntawm cov kav dej. Lub filling resin kho kom zoo compressive zog. Tom qab cov khoom siv carbon fiber ntau kho, nws muaj lub zog tensile siab heev thiab elastic modulus. Nws txwv radial expansion deformation ntawm qhov tsis xws luag, txo tensile kev nyuaj siab thiab strain ntawm qhov tsis xws luag, txwv tsis pub muaj kev ntxhov siab ntawm qhov tsis xws luag, ua tiav qhov kev txhawb nqa thiab kho cov kav dej, rov ua kom lub cev muaj peev xwm, thiab txo cov raj xa dej.
Cov pa roj carbon fiber ntau cov khoom siv kho qhov system siv cov tshuaj kho tshwj xeeb los sau thiab kho qhov tsis xws luag, nrog rau tus neeg saib xyuas kho kom muaj zog compressive zoo tshaj 100MPa. Tus neeg saib xyuas kho tshwj xeeb thiab epoxy primer ua kom hloov siab raws li radial kev taw qhia ntawm cov yeeb nkab phab ntsa. Los ntawm qhwv cov pa roj carbon fiber ntau thiab epoxy resin rau sab nraud ntawm lub raj xa dej, cov resin kho kom tsim cov khoom siv carbon fiber ntau, uas tom qab kho, muaj zog tensile siab. Los ntawm tus neeg saib xyuas kev kho tshwj xeeb thiab kev sib txuas ntawm nws tus kheej thiab cov kav dej, nws tuaj yeem hloov siab, sib koom nrog lub siab ntawm lub raj xa dej, txwv cov yeeb nkab expansion deformation, txo tensile kev nyuaj siab thiab strain ntawm qhov tsis xws luag, thiab ua tiav kev txhim kho thiab kho cov kav dej tsis zoo.
Cov pa roj carbon fiber ntau cov khoom siv txhawb nqa thiab kho tshuab yog qhov muaj kev nyab xeeb thiab txhim khu kev qha cov raj xa dej thiab kho tshuab uas tuaj yeem daws qhov teeb meem xws li corrosion thiab mechanical puas hauv cov kav dej. Nrog rau kev tshawb fawb txuas ntxiv mus rau cov khoom siv carbon fiber ntau, daim ntawv thov ntawm cov khoom siv carbon fiber ntau yuav txuas ntxiv.
