Popanga mafakitale, mapaipi ali ngati "mitsempha yamagazi" ya zida, zomwe zimanyamula zinthu "zotentha" monga mchenga, miyala, ndi mpweya wotentha kwambiri. M'kupita kwa nthawi, makoma amkati a mapaipi wamba amatha kutha mosavuta ndipo amatha kutayikira, zomwe zimafuna kukonzedwa pafupipafupi komanso kusinthidwa, komanso zimatha kuchedwetsa kupanga. M'malo mwake, kuwonjezera "zovala zapadera zodzitetezera" papaipi kumatha kuthetsa vutoli, lomwe ndizitsulo za silicon carbide pipelinetikambirana lero.
Anthu ena angafunse, kodi kwenikweni chiyambi cha silicon carbide ceramics chomwe chimamveka ngati "hardcore" ndi chiyani? Mwachidule, ndi chitsulo cha ceramic chopangidwa ndi zinthu zolimba monga silicon carbide kudzera munjira zapadera, ndipo mbali yake yayikulu ndi "kukhazikika": kuuma kwake ndi kwachiwiri kwa diamondi, ndipo imatha kupirira kukokoloka kwa mchenga ndi miyala ndi zinthu zowononga pang'onopang'ono, mosiyana ndi zitsulo wamba zomwe zimachita dzimbiri ndi kutha, komanso zimagonjetsedwa kwambiri ndi kutentha kwapamwamba komanso kukhudzidwa kwa pulasitiki.
Pakatikati pakuyika silicon carbide lining mu mapaipi ndikuwonjezera "chotchinga cholimba" pakhoma lamkati. Mukayika, palibe chifukwa chochita khama lalikulu. Nthawi zambiri, zidutswa za silicon carbide ceramic zopangira kale zimamangiriridwa ku khoma lamkati la payipi ndi zomatira zapadera kuti apange wosanjikiza wathunthu woteteza. Chosanjikiza ichi cha 'chotchinga' sichingawoneke chokhuthala, koma ntchito yake ndiyothandiza kwambiri:
Choyamba, ndi 'kukana kuvala kwathunthu'. Kaya ikunyamula tinthu tating'onoting'ono tokhala ndi m'mbali zakuthwa kapena slurry wothamanga kwambiri, pamwamba pa silicon carbide lining ndi yosalala kwambiri. Zinthu zikadutsa, kukangana kumakhala kochepa, komwe sikungowononga kansalu, komanso kumachepetsa kukana panthawi yoyendetsa zinthu, kumapangitsa kuti kuyenda bwino. Mapaipi wamba angafunike kukonzedwa pambuyo pa theka la chaka atang'ambika, pomwe mapaipi okhala ndi silicon carbide lining amatha kukulitsa moyo wawo wautumiki, kuchepetsa zovuta ndi mtengo wakusintha mapaipi mobwerezabwereza.
Ndiye pali "kukana dzimbiri ndi kukana kutentha kwapawiri mzere". M'mafakitale ambiri, zinthu zomwe zimaperekedwa zimanyamula zinthu zowononga monga asidi ndi alkali, ndipo kutentha sikutsika. Zomangira wamba zimakhala ndi dzimbiri komanso zosweka, kapena zimapunduka chifukwa cha kutentha kwambiri. Koma silicon carbide ceramics eni ake ali ndi zinthu zokhazikika zama mankhwala ndipo samawopa kukokoloka kwa asidi ndi alkali. Ngakhale atakumana ndi kutentha kwambiri kwa madigiri seshasi mazana angapo, amatha kukhala osasunthika, kuwapangitsa kukhala oyenera kugwiritsira ntchito mapaipi "malo ovuta" monga mankhwala, zitsulo, ndi migodi.
Mfundo ina yofunika ndi "nkhawa zopanda pake komanso zopanda mphamvu". Mapaipi okhala ndi silicon carbide safuna kutsekedwa pafupipafupi kuti akonzere, komanso amakhala osavuta kuwongolera - pamwamba simakonda kukulitsa kapena kupachikidwa kwa zinthu, ndipo amangofunika kutsukidwa pang'ono pafupipafupi. Kwa mabizinesi, izi zikutanthauza kuchepetsa chiwopsezo cha kusokonezeka kwa kupanga ndikupulumutsa ndalama zambiri zogwirira ntchito yokonza ndi zinthu zakuthupi, zomwe ndizofanana ndi "kukhazikitsa kamodzi, kusakhala ndi nkhawa kwanthawi yayitali".
Anthu ena angaganize kuti chinsalu cholimba choterocho ndi chokwera mtengo kwambiri? Ndipotu, kuwerengera "akaunti ya nthawi yayitali" ndi yomveka bwino: ngakhale kuti mtengo woyamba wazitsulo wamba ndi wotsika, uyenera kusinthidwa miyezi itatu kapena isanu; Ndalama zoyamba za silicon carbide lining ndizokwera pang'ono, koma zitha kugwiritsidwa ntchito kwa zaka zingapo, ndipo mtengo wapakati patsiku ndi wotsika kwenikweni. Kuphatikiza apo, imatha kupewa kuwonongeka kwapaipi komwe kumachitika chifukwa cha kuwonongeka kwa mapaipi, ndipo mtengo wake ndiwokwera kwambiri.
Masiku ano, kupaka mapaipi a silicon carbide pang'onopang'ono kwakhala "njira yabwino" yotetezera mapaipi a mafakitale, kuchokera kumapaipi omwe amanyamula mapaipi mumigodi, kupita ku mapaipi azinthu zowononga mumakampani opanga mankhwala, kupita ku mapaipi amafuta amafuta apamwamba kwambiri pamsika wamagetsi, kupezeka kwake kumawonedwa. Mwachidule, zili ngati "mlonda waumwini" wa mapaipi, akuyang'anira mwakachetechete ntchito yosalala ya mafakitale ndi kuuma kwake komanso kulimba kwake - ichi ndi chifukwa chake makampani ochulukirapo akulolera kupanga mapaipi ndi "zovala zapadera zotetezera" izi.
