Since the ductile iron pipes currently on the market are not resistant to wear and corrosion, their inner walls have recently been coated with epoxy resin as anti-corrosion materials. But there are also 1. Not wear-resistant. 2. Disadvantages such as poor coating peel strength.

 

 

1. Corrosion resistance

 

2. Its wear resistance and peel strength are very superior.

 

3. Easy to use in industrial wastewater.

 

4. The internal anti-corrosion coating is: double epoxy resin coating, adding dispersed quartz powder and additives with high wear resistance.

 

5. Belongs to the epoxy ceramic coating series, including DH101 black epoxy ceramic coating (black pottery for short). DH102 white epoxy ceramic coating (white ceramic for short).

 

6. The curing agents and additives used in epoxy ceramic black pottery DH101 and white pottery DH102 are different. The component B of DH101 appears as a black viscous liquid, while the component B of DH102 appears as a white viscous liquid.

 

7. Epoxy ceramic black pottery DH101 lined ductile iron pipes are mainly used to transport sewage and drainage ductile iron pipes

Ceramic lined ductile iron pipe is a new type of lined ductile iron pipe. It is a drainage pipe manufactured using a special lining treatment process. Pipes used in sewage and drainage works.

 

8. Ductile iron pipes lined with epoxy ceramic white pottery DH102 are mainly used to transport drinking water and gray water, and can also be used for sewage, drainage, industrial and chemical wastewater.

 

 

Epoxy ceramic lined ductile iron pipe is a specially lined ductile iron pipe. Its inner wall is made of two-component epoxy resin paint as the main material, plus organic quartz powder and additives to improve the Wear resistant, corrosive and fluid transfer efficient. This pipe has the following advantages:

 

1. Safety, complying with safety and environmental protection requirements.

The epoxy ceramic coating lining the ductile iron pipe is a solvent-free coating and does not emit any volatile solvents when used.

 

2. The pressure along the process is comfortable and small, the surface is as smooth as a mirror, and the average coating thickness is 1000-2000um, which is much lower than that of cement-lined pipes. Moreover, the roughness coefficient of epoxy ceramic is less than 0.008, while that of ordinary cement is 0.014, which increases its flow rate by 10-20% compared with ordinary cement-lined pipes, thus greatly reducing the design investment of the power system.

 

3. Wide temperature adaptability: Epoxy ceramic coating is very suitable for areas with large temperature differences. After repeated tests on finished pipes, the coating was subjected to repeated temperature rises and falls under the conditions of -22.5° to +100°. There is no change in the surface and the combination with the base material.

 

4. Internal anti-scaling: The epoxy ceramic coating has good smoothness, which can effectively prevent scaling on the inner wall of the pipeline and ensure the long-term smooth operation of the pipeline.

 

 

 

 

Pipe diameters below 300mm are bundled with steel strips, and pipes above 300mm are packed in bulk.
