Monga chitsulo chofunikira kwambiri komanso chofunikira kwambiri pakupanga chuma cha dziko, mapaipi achitsulo osapindika amagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, kukonza makina, ndi uinjiniya wa mapaipi (kunyamula madzi ndi zinthu zolimba monga madzi, mafuta, gasi, malasha, ndi nthunzi ya boiler). Chifukwa cha malo osiyanasiyana ogwiritsira ntchito ndi kugwiritsa ntchito, ndikofunikirabe kusankha zipangizo ndi miyezo yoyenera posankha kuti mupewe zinyalala ndi zinthu zosatetezeka.
