Advantages of epoxy coated steel pipes:



1.The epoxy coating provides exceptional corrosion resistance, ensuring the pipe's durability and longevity in harsh environments.

2.The epoxy coating creates a smooth interior surface, reducing fluid friction and enhancing flow efficiency.

3.The epoxy coating is highly resistant to abrasion and wear, ensuring the pipe maintains its structural integrity and appearance over time.

4.Epoxy coated steel pipes are easy to install and maintain. The coating provides a uniform and consistent surface that is compatible with various joining methods, such as welding and flanging.

5.Epoxy coated steel pipes are environmentally friendly. The epoxy coating is non-toxic and does not release harmful chemicals into the environment. 



Material of epoxy coated steel pipe:




Steel pipe body: The main material of epoxy coated steel pipe is usually carbon steel or low alloy steel. This material ensures that the steel pipe has high strength, easy connection and water flow impact resistance.

Coating material: The inner and outer surfaces of the steel pipe are coated with a layer of epoxy resin with a thickness of 0.3 to 1.0 mm. Epoxy resin is a thermosetting resin with excellent bonding ability, corrosion resistance, heat resistance and electrical insulation.



Structure of epoxy coated steel pipe:



Basic structure: Epoxy coated steel pipe consists of three parts: steel pipe, adhesive and anti-corrosion coating.

Steel pipe: provides structural strength and support.

Adhesive: plays the role of firmly attaching the coating to the steel pipe.

Anti-corrosion coating: composed of epoxy resin, providing anti-corrosion function.

Coating structure:Primer: applied on the surface of the steel pipe as the base layer to enhance the adhesion and anti-corrosion between the coating and the steel pipe.

Main paint: applied on the primer, has good corrosion resistance and wear resistance, and protects the inner and outer surfaces of the steel pipe.



Application scope of epoxy coated steel pipe:



1. Oil and gas transportation

2. Urban water supply system

3. Sewage treatment system

4. Chemical industry

5. Power and communication industry

6. Marine engineering

7. Mining and mining

8. Fire protection system
