摘要
The present invention relates to improvement of the outside anticorrosive treatment of ductile cast iron piping members, through the development of a Pseudo Alloy metallic film on the external surface, more particularly the present disclosure relates to the improved corrosion resistant to ductile cast iron piping members, specially when used in buried condition, the coating method that can form an anticorrosion pseudo metal alloy layer in the peripheral surface and also to an arrangement to obtain uniform deposition of the pseudo alloy over the external surface of the piping member and the piping member produced by the disclosed method.
