Chingwe cha mapaipi a silicon carbide: "zida zoteteza zosatha komanso zosagwira dzimbiri" poyendetsa mafakitale

M'mafakitale monga mankhwala, zitsulo, ndi migodi, mapaipi ndiye njira zazikulu zonyamulira zinthu, ndipo njira yotumizira zinthu nthawi zambiri imakhala ndi "mphamvu yopha" monga kuwonongeka, dzimbiri, ndi kutentha kwambiri. Mapaipi wamba amatha kukalamba ndi kutuluka madzi, zomwe sizimangokhudza momwe ntchito ikuyendera komanso zimayambitsa ngozi zobisika.Chitoliro cha payipi ya silicon carbidendi chida choteteza cha mafakitale chomwe chapangidwa kuti chithetse vutoli, ndipo chakhala njira yabwino kwambiri yothetsera dzimbiri lamphamvu la mafakitale komanso kuwonongeka kwambiri chifukwa cha magwiridwe ake abwino kwambiri.
Mwachidule, silicon carbide pipeline lining ndi gawo loteteza la silicon carbide material composite pakhoma lamkati la payipi, zomwe zimayika "zida" zolimba pa payipi. Mosiyana ndi zitsulo wamba kapena pulasitiki, silicon carbide yokha ndi chinthu chapadera cha ceramic chomwe chimasinthasintha bwino ku ntchito zovuta, zomwe zimapatsa silicon carbide pipeline liners ubwino waukulu womwe umawasiyanitsa ndi zitsulo zachikhalidwe.
Kukana kuvala ndi kukana dzimbiri ndi zinthu zofunika kwambiri pa mapaipi a silicon carbide. Mu mayendedwe a mafakitale, zinthu monga slurry, ufa, acid alkali solution, ndi zina zotero zimakhala zolimba kwambiri ndipo zimatha kuwonongeka kwa mapaipi, kapena zimakhala ndi dzimbiri kwambiri ndipo zimatha kuwonongeka makoma a mapaipi. Zinthu za silicon carbide zimakhala zolimba kwambiri, pambuyo pa diamondi, ndipo zimatha kukana kuwonongeka ndi kuwonongeka kwa zinthu zosiyanasiyana zolimba; Nthawi yomweyo, zimakhala ndi mankhwala okhazikika ndipo siziopa dzimbiri la asidi ndi alkali kapena kutentha kwambiri. Ngakhale zitagwira ntchito m'malo amphamvu a asidi ndi alkali, kutentha kwambiri kwa nthawi yayitali, zimatha kusunga kukhazikika kwa kapangidwe kake ndikuchepetsa kwambiri kuwonongeka kwa mapaipi ndi kutuluka kwa madzi.
Kukana kutentha kwambiri komanso kutentha bwino kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo ovuta kwambiri. Zipangizo zambiri zomwe zimapangidwa m'mafakitale zimafunika kunyamulidwa m'malo otentha kwambiri, ndipo ma liners wamba amatha kusinthika komanso kukalamba chifukwa cha kutentha kwambiri. Komabe, silicon carbide imatha kupirira kutentha kwambiri ndikukwaniritsa zofunikira zapadera za malo otentha kwambiri, zomwe zimapangitsa kuti mapaipi azigwiritsidwa ntchito kwambiri.

Kuphatikiza apo, mapaipi a silicon carbide alinso ndi ubwino wokhala ndi moyo wautali komanso ndalama zochepa zosamalira. Mapaipi achikhalidwe amafunika kusinthidwa ndi kukonzedwa pafupipafupi, zomwe sizimangowononga anthu ndi zinthu zokha, komanso zimachedwetsa kupita patsogolo kwa kupanga. Kulimba kwa mapaipi a silicon carbide ndi kolimba kwambiri, ndipo kumatha kugwira ntchito mokhazikika kwa nthawi yayitali ndi kuyika kamodzi, zomwe zimachepetsa kwambiri kuchuluka kwa kukonza ndikusintha mtsogolo. Pamapeto pake, zimatha kusunga ndalama zambiri zogwirira ntchito ndi kukonza mabizinesi ndikuwonetsetsa kuti kupanga kupitilira.
Chifukwa cha kufunikira kwakukulu kwa chitetezo cha mayendedwe, magwiridwe antchito, komanso kukhazikika pakupanga mafakitale, mapaipi a silicon carbide agwiritsidwa ntchito kwambiri chifukwa cha zabwino zake zazikulu zokana kuwonongeka, kukana dzimbiri, komanso kukana kutentha kwambiri. Sikuti ndi gawo loteteza mapaipi okha, komanso chitsimikizo chodalirika cha kupanga chitetezo chamakampani, kuchepetsa ndalama komanso kukonza magwiridwe antchito. Pakukula kwa mafakitale apamwamba, ikukhala "udindo wapamwamba woteteza" m'munda wa mayendedwe amafakitale ndi magwiridwe ake olimba.
