Glass Fiber Pipe For Hot Line Tools / Epoxy Fiberglass Pipe Knitting And Pultruded Insulation Tube
Product
1.The concept of glass fiber pipe for hot line tools epoxy fiberglass pipe knitting and pultruded insulation tube
Glass fiber insulation is a very good insulation material. The diameter of glass fiber monofilament ranges from a few micrometers to over twenty meters per micrometer, which is equivalent to 1/20-1/5 of a hair thread. Each bundle of fiber strands consists of hundreds or even thousands of monofilaments, which are commonly used as reinforcement materials in composite materials, electrical insulation materials, insulation materials, circuit substrates, etc., and are widely used in various fields of the national economy.
Glass fiber pipes are also very common. They are made of high-purity alkali free glass fibers woven into pipes, and then coated with organic silicone on the outer wall of the pipes for vulcanization treatment. The specifications and models can be customized according to different pressure requirements. The glass fiber tube has the characteristics of good corrosion resistance, aging resistance, heat resistance, frost resistance, light weight, high strength, good designability, good electrical insulation, low friction resistance, and is widely used.

The characteristics of Glass Fiber Pipe For Hot Line Tools Epoxy Fiberglass Pipe Knitting And Pultruded Insulation Tube
1. Good corrosion resistance
Due to the use of unsaturated polyester resin and glass fiber as the main raw materials for glass fiber pipes, they can effectively resist the corrosion of acid, alkali, salt and other media, as well as the erosion of untreated domestic sewage, corrosive soil, chemical wastewater, and numerous chemical liquids. In general, they can maintain safe operation for a long time.
2. Good aging resistance and heat resistance
Glass fiber pipes can be used for a long time in the temperature range of -40 ℃ to 70 ℃, and high-temperature resistant resins with special formulas can also work normally at temperatures above 200 ℃.
3. Good frost resistance
Below -20 ℃, there will be no frost cracking after freezing inside the pipe.
4. Light weight and high strength
The relative density ranges from 1.5 to 2.0, which is only 1/4 to 1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared to high-grade alloy steel. Therefore, it has achieved remarkable results in aviation, rockets, spacecraft, high-pressure vessels, and other products that require weight reduction.
5. Good designability
Various structural products can be flexibly designed to meet usage requirements, resulting in a good overall product.
6. Good wear resistance
Place water containing a large amount of mud and sand into the pipe for a comparative test on the impact of rotational wear. After 3 million rotations, the wear depth of the inner wall of the pipe is detected as follows: 0.53mm for steel pipes coated with tar and enamel, 0.52mm for steel pipes coated with epoxy resin and tar, and 0.21mm for steel pipes treated with surface hardening. From this, it can be seen that the wear resistance of glass fiber pipes is very good.
7. Good thermal insulation
Glass fiber is a non-conductive material, and the electrical insulation of pipelines is excellent. The insulation resistance ranges from 1012 to 1015 Ω. cm, making it the most suitable for use in power transmission. The heat transfer coefficient of glass fiber pipes in areas with dense telecommunications lines and frequent lightning is very small, only 0.23, which is five thousandths of that of steel. The insulation performance of pipelines is excellent.
8. Low frictional resistance and high conveying capacity
The inner wall of the fiberglass tube is very smooth, with low roughness and frictional resistance.
