Zambiri za Ductile Iron Pipes
Amapangidwa ndi chitsulo chopangidwa ndi ductile chomwe chimagwiritsidwa ntchito pofalitsa ndi kugawa kwa Madzi a Potable omwe amakhala ndi moyo wopitilira zaka 100.Chitoliro chamtunduwu ndi chitukuko chachindunji cha chitoliro chachitsulo choyambirira, chomwe chapitilira.Ndibwino kuti muyike mobisa mizere yopatsirana.
Kufotokozera kwa Ductile Iron Pipes

Kugwiritsa ntchito mapaipi a DI
• Pogawa madzi amchere
• Kupatsira madzi aiwisi ndi oyera
• Madzi opangira mafakitale/ntchito zopangira mbewu
• Phulusa-slurry akuchitira & kutaya dongosolo
• Njira zozimitsa moto - pamphepete mwa nyanja ndi pamtunda
• Zomera zochotsa mchere
• Chimbudzi ndi mphamvu ya madzi otayira
• Kutolera ndi kutaya zinyalala za mphamvu yokoka
• Kupopera madzi a mkuntho
• Dongosolo lotayira nyansi pogwiritsira ntchito m'nyumba ndi m'mafakitale
• Njira yobwezeretsanso
• Kupaka mapaipi mkati mwa malo oyeretsera madzi ndi zimbudzi
• Kulumikizika koyima kuzinthu zofunikira ndi malo osungira
• Kumanga kuti nthaka ikhale yokhazikika
