With the improved corrosion-resistant buried nodular cast iron pipe fittings of external skin and production method |
| abstract |
The present invention relates to one kind by forming one layer of pseudo-alloy metal film and coating modified coating on the outer surface, the external preservative treatment of nodular cast iron pipe fittings is improved, the invention particularly relates to a kind of especially for the improved corrosion resistant ductile iron pipe fitting under mode of occurence, which can form one layer of anti-corrosion pseudo-alloy layer and modified cashew nut shell oil (CNSL) coating in outer surface. |
