Interpret the main features of glass fiber tube in detail

1. ကောင်းသောချေးခံနိုင်ရည်ရှိသည်။

Since the main raw materials of glass fiber reinforced plastic are composed of unsaturated polyester resin and glass fiber, it can effectively resist the corrosion of acid, alkali, salt and other media, as well as untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquids. Under normal circumstances, it can maintain safe operation for a long time.

2. Light weight and high strength.

The relative density is between 1.5 and 2.0, which is only 1/4 to 1/5 that of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, and the specific strength is comparable to that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, space vehicles, high-pressure vessels, and other products that need to reduce their own weight.

3. Good electrical and thermal insulation. FRP is a non-conductor, and the electrical insulation of the pipeline is excellent. The insulation resistance is 1012-1015Ω.cm. It is most suitable for use in power transmission, telecommunications line dense areas and mine areas. The heat transfer coefficient of FRP is very small, only 0.23, which is 1000 Fifthly, the pipeline has excellent thermal insulation performance.

4. Good designability.

Various structural products can be flexibly designed to meet the requirements of use, and the product can have a good integrity.

5. Good frost resistance.

Below minus 20°C, there will be no freeze cracking in the tube after freezing.

6. Low friction resistance and high conveying capacity. The inner wall of the glass steel pipe is very smooth, with low roughness and frictional resistance. The roughness coefficient is 0.0084, while the n value of concrete pipe is 0.014, and the value of cast iron pipe is 0.013

7. Good anti-aging performance and heat resistance performance.

The glass fiber tube can be used for a long time in the temperature range of -40℃~70℃, and the high temperature resistant resin with special formula can also work normally at temperatures above 200℃.

8. Good wear resistance.

Put water containing a large amount of mud and sand into the pipe to perform a comparative test on the effects of rotating abrasion. After 3 million rotations, the wear depth of the inner wall of the inspection tube is as follows: the steel pipe coated with tar and enamel is 0.53mm, the steel pipe coated with epoxy resin and tar is 0.52mm, and the steel pipe with surface hardening treatment is glass steel pipe It is 0.21mm. As a result, FRP has good wear resistance.
