epoxy lined ductile iron pipe has the following characteristics:

1. Belongs to drainage ductile iron pipe (ductile iron pipeline of sewer engineering)

It is produced by using qualified spheroidized molten iron through high-speed centrifugal casting, and then through annealing, hydraulic pressure and internal and external anti-corrosion treatment. It is used in pipes for drainage projects.

2. The pipe itself is made of ductile iron and can withstand the high pressure on the pipeline when the valve is opened and closed.

3. The outer coating of the pipe is protected and has good anti-corrosion properties in most soil environments.

4. After the outer zinc layer of the pipeline is coated, a high-chlorinated polyethylene finishing layer is applied again. It has been proven to be one of the most effective anti-corrosion measures around the world and can effectively extend the service life of the pipeline.

5. Mechanical properties of epoxy lined ductile iron pipe:

DN1100-DN1200	≥420	≥300	≥7	≤230

 

 

Epoxy lined ductile iron pipe is a specially treated ductile iron pipe with an epoxy resin coating on the inner wall to improve the pipeline's corrosion resistance and fluid transport efficiency. This pipe has the following advantages:

1. Has strong corrosion resistance. Due to the special material of the pipe itself, the internal coating material uses epoxy resin paint. This material has good acid and alkali resistance, corrosion resistance, and can resist the erosion of various chemical substances.

2. Has strong pressure resistance. Fusion bonded epoxy ductile iron pipe can withstand higher pressure and has better resistance to explosion pressure and earthquake pressure.

3. Has good sealing performance. Due to the tight combination between the epoxy resin material of the inner coating and the inner wall of the pipe (or cement lining structure), the pipe has better sealing performance and can effectively prevent leakage.

4. Has strong rigidity and toughness. fusion bonded epoxy ductile iron pipe

It has good rigidity and toughness, can remain stable in various complex environments, and is not easy to deform or break.

 

 

 

 

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