Mapaipi amkuwa amalimbana ndi kutentha kwambiri ndipo amatha kugwiritsidwa ntchito m'malo osiyanasiyana.Poyerekeza ndi izi, zofooka za mapaipi ena ambiri ndi zoonekeratu.Mwachitsanzo, mapaipi achitsulo omwe amagwiritsidwa ntchito m'nyumba zogona m'mbuyomo ndi osavuta kuchita dzimbiri.Ngati sagwiritsidwa ntchito kwa nthawi yayitali, padzakhala mavuto monga chikasu cha madzi apampopi ndi madzi ochepa.Palinso zipangizo zina zomwe mphamvu zake zidzachepa mofulumira pa kutentha kwakukulu, zomwe zingayambitse ngozi zosatetezeka zikagwiritsidwa ntchito m'mipope ya madzi otentha.Malo osungunuka a mkuwa ndi okwera kufika madigiri 1083 Celsius, ndipo kutentha kwa madzi otentha kumakhala kosavomerezeka kwa mapaipi amkuwa.Akatswiri ofukula zinthu zakale anapeza chitoliro cha madzi amkuwa zaka 4,500 zapitazo m’mapiramidi a ku Aigupto, amene akugwiritsidwabe ntchito lerolino.
1) Kugwiritsa ntchito ukadaulo wopitilira muyeso wopitilira ndi kugubuduza kupanga, kuyera kwakukulu, kapangidwe kabwino, okhutira okosijeni otsika.
2) Palibe pores, trachoma, porosity, yokhala ndi matenthedwe abwino amafuta, processability, ductility, kukana kwa dzimbiri komanso kukana kwanyengo.
3) yosavuta kuwotcherera ndi braze.
4) Chogulitsacho chimakhala chokhazikika, kukana kuthamanga kwambiri, kutalika kwambiri, komanso ukhondo wambiri, kukwaniritsa zofunikira zaukhondo pazida zopanda firiji zopanda fluorine.
