Amapayipi e-iron ductile akhiqizwa ngokuya nge-ISO2531/EN545/EN598/NBR7675 standard international.I-Ductile cast iron iwuhlobo lwe-alloy yensimbi, ikhabhoni ne-silicon.Ngesikhathi senqubo yokukhiqiza, senza izivivinyo kulayini ngokuqinile futhi izinto zokuhlola zihlanganisa: ingcindezi ye-hydraulic, ukujiya kolayini lukasimende, ukushuba kokufafaza kwe-zinc, ukujiya kwebitumen, ukuhlolwa kobukhulu, ukuhlolwa okuhlaba umxhwele nokunye.Ikakhulukazi, sinomtshina we-X-ray oseqophelweni eliphezulu kakhulu wokuhlola ukujiya kodonga lwepayipi ngalinye ngokunembile ukuze siqinisekise ukuthi izinga lamapayipi liyavumelana nezinga.
I-Coating: I-Epoxy Resin Paints&Powder Coating, i-bitumen coating.
