How can the ductile iron pipes be treated with corrosion protection?
Bituminous paint coatingBituminous paint coatings are pipes used to carry gas. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate drying
Epoxy coal tar coatingThe epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipes. It is a two component coating with a high adhesion and a very smooth surface
Cement mortar lining + special coatingThe internal corrosion prevention measures are suitable for pipes conveying sewage, and the corrosion resistance of lining can be improved.
