What are the measures to avoid corrosion of cast iron pipe? Shared by Malleable Iron Pipe Fittings Supplier.
1, bitumen paint coating: bitumen paint coating is mainly used for conveying gas pipelines. Preheating the pipe before painting can improve the adsorption force of bitumen paint and speed up the drying.
2, cement mortar lining + special coating: this internal anticorrosion measure is applicable to the pipeline transporting sewage, can improve the corrosion resistance of the lining.
3, epoxy coal-asphalt coating: epoxy coal-asphalt coating is applicable to both gas pipelines and sewage pipelines. It is a two-component coating with high adhesion and a smooth surface.
4, epoxy ceramic lining: epoxy ceramic lining is suitable for sewage and gas pipelines. However, due to the difficulty of manufacturing process and high cost, it has certain limitations in use. Epoxy ceramic lining is an excellent anticorrosive coating with high adhesion and finish.
5, aluminate cement coating or sulfate cement coating: these two kinds of special cement coating are suitable for the internal corrosion protection of ductile iron pipes used in sewage pipes, to improve the ability to resist the corrosion of acid and alkali components in sewage.
6, polyurethane coating: is a new type of green special coating developed to meet the requirements of environmental protection, with good wear resistance and corrosion resistance.
