Ezimbonini lapho ukuthutha izinto ezihudulayo kuyinto evamile yokusebenza kwansuku zonke, ukwehluleka kwepayipi ngaphambi kwesikhathi akuyona nje inkinga yokulungisa—kuwukushayeka ngqo emgomweni oyinhloko. Amapayipi ethu e-ceramic acwebezelayo amelana nokuguguleka e-alumina aklanywe ukuxazulula le nselele ngqo. Ngokuqukethwe kwe-alumina (Al₂O₃) okungaphezu kuka-95%, lawa mapayipi abonisa ubulukhuni be-Rockwell obuyi-HRA 85-90, okwesibili kuphela ngemva kwedayimane. Lobu bulukhuni obukhulu buhumusha ekumelaneni okungavamile nokuguguleka okushelelayo kanye nomthelela wezinhlayiya, okwandisa ngempumelelo impilo yesevisi izikhathi ezi-5 kuya kweziyi-10 uma kuqhathaniswa namapayipi ensimbi aqinisiwe endabuko. Okubaluleke kakhulu, ubulukhuni obungavamile buhambisana nobuningi obuphansi obungaba ngu-3.6 g/cm³, okwenza uhlelo lwamapayipi e-ceramic lube lula kakhulu kunezinye izindlela zensimbi, ngaleyo ndlela kuncishiswe umthwalo wesakhiwo kanye nezindleko zokufaka ngaphandle kokulahlekelwa ukuqina.
Inqubo yokukhiqiza ethuthukisiwe ibalulekile ekusebenzeni okuphezulu kwephayiphi. I-liner ngayinye yakhiwa ngenqubo yokucindezela oku-isostatic noma inqubo yokukhipha umfutho ophezulu, kulandelwe ukudubula ngokunembile kuhhavini lokushisa eliphezulu ku-1500°C–1700°C. Lokhu kushiswa okulawulwayo kuveza isakhiwo esincane esiminyene, esinobunye esinama-porosity amancane, okususa ngempumelelo amaphuzu abuthakathaka angabangela ukuguguleka. Ama-liner e-ceramic abese eboshelwa ekhasejini langaphandle lensimbi eliqinile kusetshenziswa i-epoxy resin ekhethekile enamandla aphezulu, engamelani nokushisa. Lokhu kwakhiwa okuhlanganisiwe kusebenzisa ubulukhuni be-ceramic bokumelana nokuguguleka kanye nokuqina kwensimbi yokuvikela imishini, kuqinisekisa ukusebenza okuthembekile ngaphansi kwezimo zokushaqeka kokushisa kanye nomthelela wemvamisa ephezulu. Ubuso bangaphakathi bamapayipi ethu e-ceramic bugcina ukuphela okubushelelezi okunobulukhuni obuphelele (inani le-Ra) elingaphansi kuka-0.4 μm, isici esibalulekile esinciphisa ukumelana kokungqubuzana, sikhuthaza ukugeleza kwe-laminar, futhi sinciphisa kakhulu ukulengiswa kwezinto, okwenza la mapayipi abe yinto ebalulekile ezinhlelweni zokuhambisa umoya kanye ne-hydraulic.
Ukusetshenziswa kwangempela kwamapayipi ethu e-alumina ceramic kuhlanganisa izimo eziningi eziguga kakhulu. Ezitshalweni zamandla ezisebenzisa amalahle, ziyisinqumo esithembekile semigqa yokujova amalahle e-pulverized coal injection (PCI) kanye nezinhlelo zokudlulisa umoya ze-fly ash, ezisebenza kahle kakhulu kune-basalt kanye nensimbi eqinile ngesilinganiso esikhulu. Umkhakha wezimayini kanye nokucubungula amaminerali uthembele kuwo ekuthuthweni kwama-slurry aminyene njenge-iron ore concentrate, i-copper tailings, kanye nesihlabathi se-silica, lapho ukumelana kwepayipi kokubili ukuguguleka kanye nokugqwala kwamakhemikhali okuvela kuma-slurry ane-acidic noma e-alkaline kubaluleke kakhulu. Ngaphezu kwalokho, embonini yesamente, insimbi, kanye nomanyolo wamakhemikhali, la mapayipi aqinisekisa ukuqhubeka kokusebenza ezindaweni ezibalulekile ezibhekene nokuvinjelwa kwezinhlayiya ezinejubane eliphezulu. Ekugcineni, ukutshala imali kumapayipi ethu e-alumina ceramic kuyisinqumo esibalulekile—ukufaka esikhundleni sokugcinwa okusabelayo ngokuthembeka okusebenzayo, ukunciphisa kakhulu isikhathi sokungasebenzi esingahleliwe, kanye nokuletha izindleko eziphansi zobunikazi kulo lonke umjikelezo wokuphila kwempahla.
