Anti-corrosion Treatment Of Ductile Iron Pipe

Nov 22, 2018

With the improvement of people's living standards, the city is getting bigger and bigger, the population is more and more, the sewers in the city are also more and more, and the sewers are made of Ductile Iron Pipe. Therefore, the anti-corrosion treatment of ductile iron pipes is becoming more and more important. China professional Ductile Iron Pipes Wholesaler tell you about the anti-corrosion treatment of ductile iron pipes.

1. Asphalt paint coating

Asphalt paint coating is a pipe used to transport gas. Preheating the tube before painting can improve the adhesion of the asphalt paint and accelerate drying.

2. Cement mortar lining + special coating

This internal anti-corrosion measure is suitable for Ductile Iron Pipe with Tyton Joint that transport sewage, which can improve the corrosion resistance of the lining.

3. Epoxy coal tar pitch coating

Epoxy coal tar pitch coating is suitable for both gas pipelines and sewage pipelines. It is a two-component coating with high adhesion and a very smooth surface

3. Epoxy ceramic lining

Epoxy ceramic lining is suitable for sewage pipes and gas pipes, but due to the difficulty in manufacturing process and high cost, it has certain limitations in use. Epoxy ceramic lining is a good anti-corrosion coating with high adhesion and smoothness.

5. Aluminate cement coating or sulfate cement coating

These two special cement coatings are suitable for internal corrosion protection of Tyton Joint Ductile Iron Pipe for sewage pipelines, and improve the resistance to corrosion of acid and alkali components in sewage.

1. Polyurethane coating

It is a new type of green special coating developed to meet the needs of environmental protection, with good wear resistance and corrosion resistance.
