Asphalt paint coating
Asphalt paint coating is used to transport gas pipeline. Preheating the pipe before painting can improve the adhesion of asphalt paint and accelerate drying.
Cement mortar lining + special coating
This kind of internal anti-corrosion measure is suitable for the pipeline conveying sewage, and can improve the anti-corrosion ability of the lining.
Coal tar epoxy coating
Epoxy coal tar pitch coating is suitable for both gas pipeline and sewage pipeline. It is a two-component coating with high adhesion and a very smooth surface
Epoxy ceramic lining
Epoxy ceramic lining is suitable for sewage pipeline and gas pipeline, but because of the difficulty of manufacturing process and high cost, it has some limitations in use. Epoxy ceramic lining with high adhesion and finish is an excellent anticorrosion
Aluminate cement coating or sulfate cement coating
These two kinds of special cement coatings are suitable for the internal corrosion protection of ductile iron pipes for sewage pipes, and improve the corrosion resistance of acid and alkali components in sewage.
It is a new type of special green coating developed to meet the needs of environmental protection
