Ukuthuthwa nokufakwa kwepayipi lensimbi eline-Ceramic-lined kulula kakhulu, ipayipi lensimbi eline-ceramic lined nepayipi lensimbi, ipayipi lengxube ye-alloy engagugi, ipayipi lensimbi elicijile kanye nokuqhathaniswa kwamapayipi amatshe, isisindo esincane, kulula ukuthuthwa. Ipayipi lensimbi eline-Ceramic-lined elihlanganisiwe lingashiselwa, ama-flanges, izixhumi eziguquguqukayo kanye nezinye izindlela zokuxhuma okusheshayo, ngakho ukufakwa nakho kulula kakhulu.

Ngomkhakha:
1. Amapayipi angagugi kakhulu adingekayo: amandla ashisayo, izinto zokuhamba zomlotha wesikhungo samandla ashisayo (slag), ipayipi lamalahle, izinsalela ze-concentrator namapayipi agxilile, amachweba namapayipi odaka lwenhlabathi aphihlize amapayipi odaka lwamalahle nokunye okunjalo.
2. Aminyene Amapayipi amalahle okhethweni olumaphakathi (awashiwe) amalahle, izidingo eziphakeme zokumelana nokugqwala zamaphayiphi akhipha amandla ashisayo e-desulphurization.
3. Amapayipi e-aluminium ancibilikisiwe.
4. Idinga ukumelana nokugqoka okuphezulu, ukumelana nokugqwala okuphezulu, izinga lokushisa eliphakeme elihlukahlukene lamashaneli.
