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.
