The main features of glass fiber tubes
Low friction and high conveying capacity. Glass steel tubes have very smooth inner walls with very little roughness and friction. The roughness coefficient is 0.0084, while the n value of concrete pipe is 0.014, and the cast iron pipe is 0.013
Good electric insulation. The glass steel pipe is a non conductor, the electrical insulation characteristic, insulation resistance in 1012-1015.Cm, used in the transmission to the heat transfer coefficient of telecommunication lines and dense areas of minefield of glass steel is very small, only 0.23, is 5/1000 of steel pipe, insulation performance is excellent.
Good wear resistance. The water containing a large amount of mud and gravel is loaded into the pipe to carry out rotary abrasion, and the contrast test is carried out. After 3 million times of rotation, detection of wear depth of inner tube as follows: steel and tar enamel coating for 0.53mm steel, epoxy resin and tar coating for 0.52mm steel by surface hardening treatment for steel pipe for 0.21mm glass. Therefore, the glass fiber reinforced plastic has good abrasion resistance.
1, good corrosion resistance. The composition of main raw materials of glass fiber reinforced polymer composition used in unsaturated polyester resin and glass fiber, can effectively resist the corrosion of acid, alkali, salt and other medium and untreated sewage, soil corrosion, chemical wastewater and many chemical liquid erosion, in general, to maintain safe operation for a long time.2, anti-aging and good heat resistance. Glass fiber tubes can be used for a long time in the temperature range from -40 to 70 degrees Celsius, and adopt special formula of high temperature resistant resin, and can work at normal temperature above 200 degrees celsius.3, good frost resistance. Minus 20 degrees below freezing in tube will not happen after cracking.4, light weight, high strength. The relative density is between 1.5~2.0 and only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, while the specific strength can be compared with that of advanced alloy steel. As a result, aviation, rockets, aerospace vehicles, high pressure vessels, and other applications that need to reduce weight have excellent results.5. Good design. Can flexibly design a variety of structural products to meet the use of requirements, you can make the product has a good integrity.
