Nodular cast iron pipe
Mapaipi achitsulo opangidwa ndi chitsulo cha nodular kwenikweni ndi mapaipi achitsulo a ductile, omwe amakhala ndi chitsulo komanso mawonekedwe achitsulo, chifukwa chake amatchedwa. Graphite mu mipope chitsulo ductile alipo mu mawonekedwe ozungulira, ndi ambiri kukula 6-7 sukulu. Pankhani ya khalidwe, mulingo wa spheroidization wa mapaipi achitsulo otayidwa umayenera kuyendetsedwa pamlingo wa 1-3, ndi spheroidization rate ≥ 80%. Chifukwa chake, zida zamakina zazinthuzo zakhala zikuyenda bwino, zomwe zimakhala ndi chitsulo komanso zitsulo. Pambuyo pa annealing, microstructure ya ma ductile iron mapaipi ndi ferrite ndi pearlite pang'ono, yomwe imakhala ndi makina abwino, motero imatchedwanso mipope yachitsulo yachitsulo.

Chitoliro cha Premium Welded Black Iron Pipe ndi Tube: 3 Inchi Diameter, Mtengo Wopikisana
M'malo omanga, kufunika kwa zipangizo zolimba komanso zodalirika sizingatheke. Chimodzi mwazinthu zofunika kwambiri zotere ndi chitoliro chakuda chachitsulo ndi chubu. Zomangamanga zolimba komanso zosunthika izi zimagwira ntchito yofunika kwambiri pantchito yomanga. Kaya ndi pomanga mapaipi, mizera ya gasi, kapena zomangira zomangira, mapaipi achitsulo ndi machubu akuda ndi mbali yofunika kwambiri pa ntchito yomanga masiku ano.
