Fibreglass Square tubeis made of silicon dioxide, aluminum oxide, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., it can be divided into non-alkali fibreglass Square tube, medium-alkali fibreglass Square tube, and high-alkali fibreglass Square tube. So what are the features of fibreglass Square tubes?

1. Good corrosion resistance.

It is mainly composed of unsaturated polyester resin and fibreglass Square tube, which can effectively resist the corrosion of acid, alkali, and salt, and the erosion of domestic sewage, corrosive soil, chemical wastewater, and other chemical liquids, keep running safely for a long time. So it's more commonly used in pipes.

2. Anti-aging, heat-resistant.

It can be used for a long time in the temperature of -40°C ~ 70°C, and some special high-temperature resistant resins can work normally above 200 ° C.

3. Anti-freeze.

Ice in the fibreglass Square tubewill not crack if it freezes below -20°C.

4. Lightweight, high strength.

Relative density is only 1/4 ~ 1/5 of carbon steel, but tensile strength is close to or even more than carbon steel, specific strength can be compared with high-grade alloy steel. Therefore, it is widely used in aviation rockets, space vehicles, and high-pressure vessels.

5. Good design.

You can design a variety of products to meet the needs of multiple directions, but also the integrity of the product is very good. Whether it is square, round, porous, or profiled, can be based on customer requirements to develop.

6. The friction resistance is small, and the conveying capacity is high.

The inside of the fibreglass Square tubeis very smooth with little friction. It is only slightly larger than a cast-iron pipe and much smaller than a concrete pipe.

7. Good electrical insulation.

Fibreglass Square tubeis a non-conductor, excellent electrical insulation, especially suitable for power transmission. The fibreglass Square tubehas a very low coefficient of heat transfer of 0.23, which is 5/1000th of steel, in areas with dense telecommunication lines and minefields, so it has excellent insulation and can not overheat and cause a fire.

Those are the features of fibreglass Square tubes, so feel free to contact us if you have any other questions.
