Product introduction

In the heating system, the oxygen in the water will seriously corrode the metal surface of heat transfer, reduce the life of the system, the heating system boiler, radiator will be its main corrosion objects. Because the oxygen content in the water is related to the water temperature, high temperature, low oxygen content, high low temperature, oxygen rate - dissolved oxygen in the water can absorb or due to temperature change, and thus oxygen will be through the pipeline surface into the water in the pipeline, in the high temperature heat exchange surface such as household boiler, water segregator and heat dissipation in the release, chemical reaction with the metal, causing corrosion.

EVOH is commonly used for food grade fresh preservation packaging coating, such as milk, beverage packaging, through the characteristics of low permeability of EVOH oxygen rate, extend the shelf life of food, longyue EVOH oxygen resistance pipe is the application of this technology to the pipeline, extend the service life of the system.

EVOH has high crystallinity, good heat resistance and will not decrease in the long-term heating process

Product features

1. Under normal operating conditions, the pipeline can be used safely for more than 50 years;

2. With good flexibility, the bending radius can be as small as 5 times of the outer diameter of the pipe, making it convenient and economical to lay;

3. The internal friction loss is small, and the conveying fluid capacity of the pipe is 30% larger than that of the metal pipe with the same diameter;

4, good chemical corrosion resistance, long service life;

5. Good environmental adaptability and excellent scratch resistance;

6. Uniform crosslinking degree, smooth inner wall, not easy to scale;

7. Good heat dissipation performance with thermal conductivity of 0.4wt/rn.

8. Through the characteristics of low permeability oxygen rate of EVOH, oxygen is blocked from entering the pipe and the service life of the system is prolonged.
