Mu mafakitale opanga mapaipi, mapaipi ali ngati "mitsempha yamagazi" yomwe imanyamula zinthu, koma amatha kukumana ndi zoopsa paumoyo monga kuwonongeka, dzimbiri, ndi kutentha kwambiri. Mapaipi wamba nthawi zambiri sangapirire kwa nthawi yayitali, ndipo kukonza pafupipafupi sikungochedwetsa kupanga komanso kumawonjezera ndalama. Kubwera kwapayipi ya silicon carbide yolumikizirayaika "suti yoteteza yolimba" pa mapaipi a mafakitale, kuthetsa mavutowa mosavuta.
Anthu ena angakhale ndi chidwi chofuna kudziwa, kodi silicon carbide ndi chiyani kwenikweni? Ndipotu, ndi chinthu chapadera cha ceramic chopangidwa ndi silicon ndi carbon, chomwe mwachibadwa chimakhala ndi jini ya "yolimba komanso yolimba". Kuuma kwake kumakhala kwakukulu kwambiri, kwachiwiri kuposa diamondi. Ponyamula ufa wa mchere ndi zinthu zosungunuka m'moyo watsiku ndi tsiku, ngakhale kukangana kwakukulu kumakhala kovuta kusiya zizindikiro pamwamba pake. Mosiyana ndi mapaipi wamba achitsulo, posachedwa adzakhala opyapyala ndi kubowoka. Ndipo mphamvu zake zamankhwala ndizokhazikika kwambiri, kaya ndi asidi wamphamvu ndi alkali chemical media kapena slurry yosungunuka, sizingawononge mosavuta, kupewa chiopsezo cha dzimbiri ndi kutuluka kwa mapaipi kuchokera muzu.
Kukana kutentha kwambiri ndi ubwino waukulu wa mapaipi a silicon carbide. Pakupanga mafakitale, zinthu zambiri zimafunika kunyamulidwa m'malo otentha kwambiri. Mapaipi wamba amatha kusinthika komanso kukalamba akamaphika kwa nthawi yayitali kutentha kwambiri, zomwe zimakhudza chitetezo cha mayendedwe. Ndipo mapaipi a silicon carbide amatha kupirira kutentha kwambiri, kaya ndi mpweya wotentha kwambiri kapena zinthu zotentha, amatha kunyamulidwa bwino mokhazikika.
Poyerekeza ndi njira zachikhalidwe zotetezera mapaipi, silicon carbide lining ilinso ndi zinthu zina zopanda nkhawa. Kapangidwe kake ndi kokhuthala, pamwamba pake ndi posalala komanso pathyathyathya, ndipo sikophweka kupachika kapena kukulitsa ponyamula zinthu. Imatha kuchepetsa zotsalira za zinthu ndi kutsekeka, ndikusunga magwiridwe antchito onyamula zinthu kukhala olimba. Nthawi yomweyo, kuchuluka kwake kumakhala kotsika kwambiri kuposa kwachitsulo, ndipo kuyika payipi sikudzawonjezera kulemera konse. Kaya ndi kuyiyika kapena kukonza pambuyo pake, ndikosavuta ndipo kungachepetsenso katundu woyika mapaipi, kusinthana ndi zochitika zovuta kwambiri zamafakitale.
Ndikoyenera kunena kuti kusakhala ndi mphamvu kwa silicon carbide yokha kumalepheretsa kuti isagwirizane ndi zinthu zonyamulidwa. Ngakhale pazinthu zomwe zili ndi kuyera kwambiri, palibe chifukwa chodera nkhawa za kuipitsidwa komwe kumachitika chifukwa cha kusakaniza kwa zinthu zolumikizira. Kaya ndi zinthu zopangira zabwino kwambiri mumakampani opanga mankhwala kapena ufa woyera kwambiri mumakampani atsopano opanga mphamvu, zimatha kunyamulidwa molimba mtima. Ichi ndi chifukwa chofunikira chomwe madera ambiri amafakitale apamwamba amafunira kusankha.
Masiku ano, mapaipi a silicon carbide akhala "katswiri woteteza" pankhani yoyendetsa mafakitale, kuyambira mayendedwe azinthu zovuta m'migodi ndi mphamvu yotentha mpaka mayendedwe apakati a mankhwala ndi mabatire a lithiamu, kupezeka kwake kumatha kuwoneka. Imagwiritsa ntchito magwiridwe ake abwino kwambiri kuthandiza mabizinesi kuchepetsa kuchuluka kwa kukonza mapaipi, kukulitsa nthawi yogwiritsira ntchito zida, ndikupangitsa mayendedwe amafakitale kukhala ogwira ntchito bwino komanso otetezeka.
Monga akatswiri odziwa bwino ntchito za silicon carbide industrial ceramics, takhala tikupukuta bwino ma silicon carbide pipeline liners, pogwiritsa ntchito zinthu zomwe zimakwaniritsa zosowa za mafakitale kuti zitsimikizire kuti zinthu zikuyenda bwino m'mafakitale osiyanasiyana. Lolani kuti "zovala zoteteza zolimba" izi ziteteze "njira yothandiza" yoyendera mafakitale ambiri.
