Fiberglass Tubes Glass fiber impregnated
Glass fiber tube The molding process is the glass fiber silk impregnated resin in the photoelectric hot one of the high-speed polymerization device curing, traction pultrusion. As a result of the use of different varieties of resin, so there are polyester glass fiber reinforced plastic, epoxy glass fiber reinforced plastic, phenolic glass steel said. It has a light and hard, non-conductive, high mechanical strength, anti-aging, high temperature, corrosion resistance and so on.
Glass fiber tube with its unique advantages in the oil, electricity, chemicals, paper, urban water supply and drainage, factory sewage treatment, desalination, gas transportation and other industries has made a wide range of applications. With the acceleration of urbanization in China, in the face of the balance and protection of population, resources and environment, governments at all levels have increased their investment in urban infrastructure year by year. In combination with advanced science and technology needs, the variety and specifications of pipe and fittings have been continuously enriched, Production continues to increase, the quality of continuous improvement, especially the development of plastic pipe faster, become today's investment hot spots. Glass fiber tube is one of them.
1, good corrosion resistance. As the main raw material of glass fiber reinforced polymer components of unsaturated polyester resin and glass fiber composition, can effectively resist the acid, alkali, salt and other media corrosion and untreated domestic sewage, corrosive soil, chemical wastewater and many chemical liquid Of the erosion, in general, to maintain long-term safe operation.
2, anti-aging properties and good heat resistance. Glass fiber tube can be -40 ℃ ~ 70 ℃ temperature range of long-term use, the use of special formula of high temperature resin can also be more than 200 ℃ temperature normal work.
3, good frost resistance. In the minus 20 ℃ below the tube will not freeze after freezing.
4, light weight, high strength. Relative density between 1.5 to 2.0, only carbon steel 1/4 ~ 1/5, but the tensile strength is close, even more than carbon steel, and the specific strength can be compared with the high alloy steel. Therefore, in the aviation, rockets, space vehicles, high pressure vessels and other products need to reduce their weight applications, have excellent results.
5, can be designed to be good.
Can be flexible to design a variety of structural products to meet the requirements, can make the product has a good overall.
6, good wear resistance. To contain a large number of mud, sand and water, into the tube for the impact of rotating wear test. After 3 million revolutions, the depth of wear of the inner wall of the test tube is as follows: 0.53mm with tar and enamel coated steel pipe, 0.52mm with epoxy and tar coated steel pipe, surface hardened steel pipe for glass pipe Is 0.21mm. Which FRP wear resistance is good.
7, good electric insulation. FRP is non-conductor, the electrical insulation of the pipeline is excellent, the insulation resistance is 1012-1015Ω.cm, the most suitable for the transmission, the telecommunication line density area and the multi-mine area FRP heat transfer coefficient is very small, only 0.23, Fifth, the pipe insulation performance is excellent.
8, the friction resistance of small transport capacity. The inner wall of the glass pipe is very smooth, the roughness and the friction are very small. The roughness coefficient is 0.0084, while the concrete pipe has an n value of 0.014 and a cast iron pipe of 0.013
