Kwimizi-mveliso apho ukuhambisa izinto ezirhabaxa kuyinto eqhelekileyo yemihla ngemihla, ukusilela kwepayipi ngaphambi kwexesha akuyongxaki nje yokulungisa—kukuchaphazela ngqo isiphelo. Iipayipi zethu zeseramikhi ezicocekileyo kakhulu ezingagugiyo zenzelwe ukusombulula le ngxaki. Ngomxholo we-alumina (Al₂O₃) odlula i-95%, ezi pipes zibonisa ubunzima beRockwell be-HRA 85-90, obulandelayo emva kwedayimani. Obu bunzima bugqithisileyo buguqulela ekuchaseni okungaqhelekanga kwi-sliding abrasion kunye ne-particle impact, nto leyo eyandisa ubomi benkonzo ngokuphindwe ka-5 ukuya kwi-10 xa kuthelekiswa neepipes zentsimbi eqinileyo zemveli. Okubalulekileyo kukuba, ubunzima obugqithisileyo buhambelana nobunzima obuphantsi obumalunga ne-3.6 g/cm³, okwenza inkqubo yepayipi yeseramikhi ibe lula kakhulu kunezinye iindlela zesinyithi, ngaloo ndlela kunciphisa umthwalo wesakhiwo kunye neendleko zokufakela ngaphandle kokunciphisa ukuqina.
Inkqubo yokuvelisa ephucukileyo ibalulekile ekusebenzeni kakuhle kombhobho. I-liner nganye yenziwa ngenkqubo yokucinezela okanye yokuphuma koxinzelelo oluphezulu, ilandelwe kukudubula ngokuchanekileyo kwi-oven enobushushu obuphezulu kwi-1500°C–1700°C. Olu sintering olulawulwayo luvelisa isakhiwo esixineneyo, esifana nesinye esine-porosity encinci, esisusa ngempumelelo iindawo ezibuthathaka ezinokubangela ukuguguleka. Ii-ceramic liners emva koko zibotshelelwa kwi-casing yangaphandle yentsimbi eqinileyo kusetyenziswa i-epoxy resin ekhethekileyo enamandla aphezulu, enganyangekiyo kubushushu. Olu lwakhiwo oludibeneyo lusebenzisa ubunzima be-ceramic bokumelana nokuguguleka kunye nokuqina kwentsimbi yokukhusela oomatshini, ukuqinisekisa ukusebenza okuthembekileyo phantsi kweemeko zokutshatyalaliswa kobushushu kunye nempembelelo ye-frequency ephezulu. Umphezulu wangaphakathi weepayipi zethu ze-ceramic ugcina ukugqitywa okugudileyo kunye noburhabaxa obupheleleyo (ixabiso le-Ra) elingaphantsi kwe-0.4 μm, uphawu olubalulekileyo olunciphisa ukumelana nokungqubana, lukhuthaza ukuhamba kwe-laminar, kwaye lunciphisa kakhulu ukuxhonywa kwezinto, okwenza ezi payipi zibe yimfuneko kwiinkqubo zokuhambisa umoya kunye ne-hydraulic.
Ukusetyenziswa kwehlabathi lokwenyani kwemibhobho yethu ye-alumina ceramic kugubungela uluhlu olubanzi lweemeko zokuguguleka okuphezulu. Kwizikhululo zamandla ezisebenzisa amalahle, zikhetho oluthembekileyo lwemigca ye-pulverized coal injection (PCI) kunye neenkqubo zokuhambisa umoya ze-fly ash, ezisebenza ngcono kune-basalt kunye nentsimbi eqinileyo ngomda omkhulu. Icandelo lezemigodi kunye nokucubungula izimbiwa lixhomekeke kuzo ekuthuthweni kwe-slurries ezixineneyo ezifana ne-iron ore concentrate, i-copper tailings, kunye ne-silica sand, apho ukumelana kombhobho kokuguguleka kunye nokugqwala kweekhemikhali ezivela kwi-asidi okanye i-alkaline slurries kubaluleke kakhulu. Ngaphezu koko, kumashishini esamente, intsimbi, kunye nezichumisi zekhemikhali, le mibhobho iqinisekisa ukuqhubeka kokusebenza kwimijikelo ebalulekileyo ejongene nokuthintelwa kwe-particle ngesantya esiphezulu. Ekugqibeleni, ukutyala imali kwimibhobho yethu ye-alumina ceramic sisigqibo esibalulekileyo—ukutshintsha ukugcinwa okusabelayo ngokuthembeka okusebenzayo, ukunciphisa kakhulu ixesha lokungasebenzi elicwangcisiweyo, kunye nokubonelela ngexabiso eliphantsi lobunini kuyo yonke i-asethi.
