Basalt Fiber Pipelines: Kev Xaiv Tshiab rau Kev Thauj Khoom Siv Hluav Taws Xob

Hauv kev ua lag luam rau cov kav dej siab, cov ntaub ntawv sib xyaw zoo li iav Fiber, carbon fiber, thiab basalt fiber yog txhua yam siv. Txawm li cas los xij, iav fiber ntau reinforced yas (GRP) cov kav dej siab yog siv dav tshaj plaws, thaum basalt thiab carbon fiber kav tsis tshua muaj.Basalt fiber ntauComposite high-pressure kav, nrog rau lawv tshwj xeeb corrosion kuj, lub teeb yuag thiab siab zog, tsis tshua muaj dej tsis kam, thiab kev pab lub neej ntev, tab tom nrhiav kev siv dav hauv ntau yam xws li petro.Tshuajs, aerospace, thiab kev tsim kho.

Qhov zoo ntawm Basalt Fiber Pipes

Cov khoom sib piv thiab daim ntawv thov teb

Basalt fiber ntau cov kav dej yog resistant rau corrosion los ntawm ntau yam xov xwm, xws li H2S, CO2, thiab dej ntsev. Lawv kuj muaj cov yam ntxwv zoo tshaj plaws, nrog rau cov dej ntws mus txog 1.5 npaug ntawm cov kav hlau. Thaum GRP yog qhov feem ntau, cov kav dej basalt fiber ntau tab tom nrhiav cov ntawv thov hauv ntau qhov chaw vim lawv qhov kev ua tau zoo dua. Tsis tas li ntawd, basalt fiber ntau cov kav dej muaj lub zog zoo heev, yog lub teeb yuag, thiab muaj nqi qis dua. Lawv lub neej ua haujlwm tau tsim muaj tshaj 30 xyoo, thiab hauv qee qhov haujlwm, lawv tau ua tau zoo ntev li 50 xyoo. Txawm hais tias basalt fiber ntau cov kav dej tseem yog cov khoom tshiab nyob rau hauv Suav teb thiab thoob ntiaj teb, thiab cov ntawv ceeb toom engineering tsis txwv, lawv qhov kev ua tau zoo tau ua rau lawv ua lub luag haujlwm tseem ceeb hauv ntau cov kav dej siab, suav nrog cov roj av, roj av, thiab kev thauj dej tshiab, kev txhaj tshuaj dej khib nyiab, cov raj xa dej, thiab cov txheej txheem petrochemical pipelines.

Corrosion Resistance thiab Service Life

Tus qauv tsim ntawm basalt fiber ntaur cov kav dej siab muaj xws li peb txheej: ib txheej txheej sab hauv, txheej txheej txheej, thiab txheej tiv thaiv sab nraud. Lub puab txheej yog nplua nuj nyob rau hauv resin, nrog rau cov ntsiab lus ntawm ntau tshaj 70%, thiab cov ntsiab lus resin nyob rau sab hauv tuaj yeem ncav cuag 95%. Qhov no ua rau basalt fiber ntau cov kav dej kom pom qhov zoo tshaj plaws corrosion kuj, tso cai rau lawv tiv taus kev yaig mus ntev los ntawm ntau cov kua qaub thiab cov hauv paus, inorganic ntsev tov, oxidizing agents, hydrogen sulfide, carbon dioxide, thiab organic solvents. Lub neej tsim muaj ntau dua 20 xyoo, tab sis ntau cov kav dej tau nyob hauv qhov zoo tom qab ntau tshaj 30 xyoo thiab tsis tas yuav tsum muaj kev saib xyuas thaum lawv lub neej ua haujlwm.

Cov txheej txheem tsim khoom thiab tus nqi-zoo

Cov txheej txheem tsim khoom rau basalt fiber ntau high-pressure kav sib txawv heev ntawm cov iav fiber ntau cov kav dej. Nyob rau hauv tib lub fiber ntau specifications, nteg-up, thiab cov khoom siv tej yam kev mob, lub hydrostatic siab kuj ntawm basalt fiber kav yog qhov zoo dua li cov kav dej iav fiber ntau. Los ntawm kev txo tus naj npawb ntawm cov khaubncaws sab nraud povtseg, cov kav dej basalt fiber ntau tuaj yeem tswj tau lawv cov kev ua haujlwm siab thaum txo cov khoom siv raw thiab cov nqi khoom, ua rau lawv cov nqi ntau dua.

Kev tsim thiab kev ua tau zoo yam ntxwv

Tus Qauv Tsim

Cov txheej txheem peb txheej ntawm basalt fiber ntau cov kav dej, uas suav nrog cov txheej txheem sab hauv, txheej txheej txheej, thiab txheej txheej tiv thaiv, muab lawv zoo heev corrosion kuj. Cov kav dej no kuj muaj qhov ua rau qaug zog thiab ua haujlwm ntev.

Nyhav thiab Mechanical Properties

Hais txog qhov hnyav, basalt fiber ntau cov kav dej muaj qhov zoo dua. Lawv lub ntiajteb txawj nqus yog li ntawm 1.6, tsuas yog 1/4 rau 1/5 ntawm cov hlau los yog cov kav hlau cam. Kev siv tswv yim qhia tau tias rau tib lub siab sab hauv, GRP yeeb nkab ntawm tib txoj kab uas hla thiab qhov ntev tsuas yog kwv yees li 28% ntawm cov yeeb nkab steel. Lawv muaj lub zog tshwj xeeb thiab tsim nyog cov khoom siv, nrog lub zog tensile ntawm 200 txog 320 MPa, ze rau ntawm cov kav hlau, tab sis nrog lub zog tshwj xeeb dua. Qhov no tso cai rau kom txo qis hauv cov yeeb nkab tus kheej qhov hnyav thaum lub sij hawm tsim qauv, ua kom yooj yim rau cov txheej txheem installation.

Lwm cov yam ntxwv zoo tshaj

Tsis tas li ntawd, basalt fiber ntau cov kav dej muaj zog tiv taus qhov ntsuas thiab paraffin tsim, muaj cov kua dej tsis zoo, hluav taws xob rwb thaiv tsev zoo, kev sib txuas yooj yim, lub zog siab, tsis tshua muaj thermal conductivity, thiab thermal stress tsawg. Cov khoom zoo heev no ua rau kev siv dav dav ntawm basalt fiber ntau cov kav dej hauv ntau qhov chaw, nrog rau lub peev xwm rau kev nce qib thiab kev siv ntau dua yav tom ntej.
