Chitoliro chachitsulo cha ductile ndi mtundu wa chitsulo chosungunuka, chomwe ndi aloyi yachitsulo, carbon ndi silicon.Graphite mu spheroidal graphite cast iron ali mu mawonekedwe a spheroids.Nthawi zambiri, kukula kwa graphite ndi 6-7.Ubwino umafunika kuti mulingo wa spheroidization wa chitoliro choponyedwa chiwongoleredwe kukhala 1-3 (spheroidization rate ≥80%), kotero kuti zinthuzo ndizopangidwa ndi makina Ntchito yakhala ikuwongolera bwino, ndi chitsulo chachitsulo ndi ntchito yachitsulo.Chitoliro chachitsulo cha annealed ductile chili ndi metallographic kapangidwe ka ferrite kuphatikiza pearlite pang'ono, ndipo mawonekedwe ake amakina ndiabwinoko.Mipope yachitsulo imatchedwa centrifugal ductile iron mapaipi.Ili ndi chitsulo, katundu wachitsulo, ntchito yabwino kwambiri yotsutsa dzimbiri, ductility yabwino, kusindikiza kwabwino, kuyika kosavuta, ndipo imagwiritsidwa ntchito makamaka popereka madzi, kufalitsa gasi, ndi kayendedwe ka ma municipalities, mafakitale ndi migodi.Mafuta etc. Ndilo kusankha koyamba kwa mapaipi operekera madzi ndipo ali ndi ntchito yokwera mtengo kwambiri.Poyerekeza ndi mapaipi a PE, potengera nthawi yoyika, mapaipi a ductile ndi osavuta komanso ofulumira kuyika kuposa mapaipi a PE, ndipo amakhala ndi mphamvu yabwino yamkati ndi yakunja atatha kukhazikitsa;pakuwona kutsekeka kwa mpweya komanso kukana dzimbiri, mapaipi a ductile amakhala ndi mpweya wabwino atatha kuyika, ndipo Njira zingapo zothana ndi dzimbiri zingagwiritsidwe ntchito kupititsa patsogolo ntchito yotsutsa dzimbiri;Kutengera momwe ma hydraulic amagwirira ntchito, chifukwa mafotokozedwe a mapaipi a ductile nthawi zambiri amatanthawuza m'mimba mwake, zomwe mapaipi a PE nthawi zambiri amatanthawuza m'mimba mwake, chifukwa potengera zomwezo, chubu cha ductile chimatha kukwaniritsa kuthamanga kwambiri;kuchokera Pankhani ya ndalama zonse zoyika ndi kukonza, chubu cha ductile chimakhala ndi mtengo wapamwamba kwambiri.Khoma lamkati limapopedwa ndi zinki, matope a simenti ndi zida za anticorrosive.

1. Kupaka utoto wa phula
Kupaka utoto wa asphalt kumagwiritsidwa ntchito kunyamula mapaipi a gasi.Kutenthetsa chitoliro musanayambe kujambula kungathe kupititsa patsogolo kupaka utoto wa asphalt ndikufulumizitsa kuyanika.

2. Kupaka matope a simenti + zokutira zapadera
Mtundu uwu wa njira zotsutsana ndi dzimbiri zamkati ndizoyenera mapaipi otumizira zimbudzi ndipo zimatha kusintha kukana kwa dzimbiri kwamkati.

3. Epoxy malasha phula phula zokutira
Kupaka phula la malasha a epoxy ndikoyenera mapaipi onse a gasi ndi mapaipi a zimbudzi.Ndizitsulo ziwiri zomwe zimakhala ndi zomatira kwambiri komanso zosalala kwambiri.

4. Epoxy ceramic lining
Epoxy ceramic lining ndi yoyenera mapaipi a zimbudzi ndi mapaipi a gasi, koma chifukwa cha zovuta kupanga komanso kukwera mtengo kwake, zimakhala ndi zoletsa zina zomwe zimagwiritsidwa ntchito.Epoxy ceramic lining imakhala yomatira kwambiri komanso yosalala, ndipo ndi anti-corrosion zokutira zabwino.

5. Kupaka kwa simenti ya aluminate kapena zokutira simenti ya sulphate
Zonse mwazovala zapadera za simentizi ndizoyenera kuletsa kuwononga mkati kwa mapaipi achitsulo a ductile omwe amagwiritsidwa ntchito m'mapaipi a zinyalala kuti apititse patsogolo kukana kwa dzimbiri kwa asidi ndi zigawo za alkali mu zinyalala.

6. Chophimba cha polyurethane
Ndi mtundu watsopano wa zokutira zapadera zobiriwira zomwe zimapangidwira kuti zikwaniritse zosowa za chitetezo cha chilengedwe.Ili ndi kukana kwabwino kovala komanso kukana dzimbiri.
