Antiseptic Treatment of Ductile Iron Pipes

In industry, it is very important to make antiseptic treatment for Ductile Iron Pipes.

1, Asphalt paint coating

Bitumen paint is used to transport gas pipes. Pre-heating the pipe before painting can improve the adhesion of asphalt paint and speed up drying.

2, Cement mortar lining + special coating

This type of internal anticorrosive measures is suitable for the pipelines conveying sewage and can improve the anti-corrosion ability of the lining.

3, Epoxy coal tar coating

Epoxy coal tar coating is not only suitable for gas pipelines, but also for sewage pipelines. It is a two-component coating with high adhesion and a very smooth surface.

4, Epoxy ceramic lining

Epoxy ceramic lining for sewage pipes and gas pipelines, but due to the manufacturing process is difficult, high cost, so there are some limitations in the use. Epoxy ceramic lining with high adhesion and finish, is a good anti-corrosion coating.

5, Aluminate cement coating or sulfate cement coating

Both of these special cementitious coatings are suitable for internal corrosion protection of ductile iron pipes for sewer pipes and improve their ability to resist the attack of acids and alkalis in sewage.

6, Polyurethane coating

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