Basalt fiber composite high-pressure yeeb nkab, uas muaj cov yam ntxwv ntawm corrosion kuj, lub teeb yuag, siab zog, tsis tshua muaj siab tsis kam mus conveying kua thiab ntev kev pab cuam lub neej, yog dav siv nyob rau hauv petrochemical, aviation, kev tsim kho thiab lwm yam teb. Nws cov yam ntxwv tseem ceeb yog: tsis kam tiv thaiv corrosion ntawm H2S, CO2, brine, thiab lwm yam., tsis tshua muaj scale tsub zuj zuj, tsis tshua muaj waxing, kev ua tau zoo txaus, txaus coefficient yog 1.5 npaug ntawm cov yeeb nkab steel, thaum muaj lub zog zoo heev, lub teeb yuag, tsis tshua muaj nqi installation, tsim lub neej ntau dua 30 xyoo, hauv qee qhov haujlwm, txawm tias siv 50 xyoo tseem tsis muaj teeb meem. Nws cov ntawv thov tseem ceeb yog: roj av, roj av thiab cov kav dej tshiab; high-pressure pipelines xws li dej phwj tshuaj thiab downhole roj pipelines; petrochemical txheej txheem pipelines; oilfield dej phwj tuaj thiab kev kho dej khib nyiab xa mus kav; spa, lwm.
Kev ua tau zoo ntawm basalt fiber ntau lub raj xa dej:
(1) Zoo heev corrosion kuj
Cov qauv ntawm basalt fiber ntau lub raj xa dej tau muab faib ua peb ntu: txheej txheej sab hauv, txheej txheej txheej thiab txheej txheej tiv thaiv txheej. Ntawm lawv, cov ntsiab lus ntawm cov txheej txheej sab hauv yog siab, feem ntau siab dua 70%, thiab cov ntsiab lus ntawm resin-nplua nuj txheej ntawm nws sab hauv yog siab li 95%. Piv nrog rau cov kav hlau steel, nws muaj kev tiv thaiv corrosion ntau dua, xws li muaj zog acid thiab alkali, ntau yam inorganic ntsev tov, oxidation media, hydrogen sulfide, carbon dioxide, ntau yam surfactants, polymer daws, ntau cov organic solvents, thiab lwm yam. Tsuav yog cov resin matrix xaiv tau zoo, basalt fiber ntau cov kav dej muaj peev xwm tiv taus cov concentrated acid ntev ntev (tshwj tsis yog rau cov kuab tshuaj muaj zog),
(2) Kev qaug zog zoo thiab kev ua haujlwm ntev
Lub neej tsim ntawm basalt fiber ntau cov yeeb nkab yog ntau tshaj 20 xyoo, thiab qhov tseeb, nws feem ntau tsis zoo tom qab siv ntau tshaj 30 xyoo, thiab tsis muaj kev saib xyuas thaum lub sijhawm ua haujlwm.
(3) Kev kub siab-cov kabmob muaj peev xwm
Cov qib siab ntawm basalt fiber ntau cov yeeb nkab siab yog 3.5 MPa-25 MPa (txog 35 MPa, nyob ntawm phab ntsa tuab thiab suav), uas muaj kev kub siab dua piv nrog rau lwm cov kav dej uas tsis yog xim hlau.
(4) Lub teeb yuag, yooj yim rau nruab thiab thauj
Qhov tshwj xeeb lub ntiajteb txawj nqus ntawm Xuan Yan fiber ntau high-pressure yeeb nkab yog hais txog 1.6, uas tsuas yog 1/4 mus rau 1/5 ntawm cov yeeb nkab steel los yog cam khwb cia hlau yeeb nkab, thiab daim ntawv thov tiag tiag qhia tau hais tias nyob rau hauv lub premise ntawm tib lub siab, qhov hnyav ntawm FRP yeeb nkab ntawm tib txoj kab uas hla thiab ntev yog hais txog 28% ntawm cov yeeb nkab steel.
(5) Siab zog thiab tsim nyog txhua yam khoom
Basalt fiber ntau high-pressure yeeb nkab axial tensile lub zog ntawm 200-320MPa, nyob ze rau cov yeeb nkab steel, tab sis dua li lub zog yog li 4 npaug ntau dua, hauv cov qauv tsim, qhov hnyav ntawm cov yeeb nkab tuaj yeem txo qis, kev teeb tsa yooj yim heev.
(6) Lwm yam khoom:
Tsis yooj yim rau scale thiab siv quav ciab, me me ntws tsis kam, zoo hluav taws xob rwb thaiv tsev zog, yooj yim coupling, siab zog, tsawg thermal conductivity, tsis tshua muaj thermal stress.
