Large diameter fiberglass pipes, Jiahang fiberglass cable pipes, pure process ventilation pipes

Fiberglass reinforced plastic sand pipe is a new type of composite material pipe with excellent performance, which has superior performance compared to other traditional pipes (metal pipes, concrete pipes, plastic pipes): 1. Excellent water and corrosion resistance: The scientific and reasonable resin selection and process layer design of the pipeline inner lining ensure that the pipeline has excellent waterproof, anti-seepage, and chemical corrosion resistance. 2. Excellent hydraulic characteristics, energy saving, and no secondary pollution ◆ Smooth inner wall, improving conveying capacity. The roughness coefficient of the inner wall of fiberglass sand filled pipes is only 0.0084, compared to 0.04 for steel pipes, 0.014 for concrete pipes, and 0.013 for cast iron pipes. Therefore, fiberglass pipes can significantly reduce fluid pressure loss along the way and improve conveying capacity by 20-30%. Reduce the diameter and save one-time investment. When the conveying capacity is the same, the project can reduce 1-2 pipe diameter grades by selecting fiberglass sand pipes, thereby reducing one-time engineering investment. ◆ Using pipes with the same inner diameter to save operating costs, fiberglass pipes can reduce pressure head loss compared to other materials of pipes, save pumping costs, shorten pumping time, and reduce long-term operating costs. ◆ Anti fouling, anti moth, and no secondary pollution. The internal surface of the product is clean and smooth, and will not be contaminated by microorganisms such as crustaceans and fungi in the ocean or sewage, resulting in increased roughness, reduced water cross-section, and increased maintenance costs. It will not cause secondary pollution to water quality or other media. 3. The tensile strength of pipes with good mechanical properties and high specific strength is lower than that of steel, but higher than that of ductile iron pipes and concrete pipes. The specific strength is about 3 times that of steel pipes, 10 times that of ductile iron pipes, and 25 times that of concrete pipes. The tensile strength of the pipeline is ≥ 320 Mpa, and the impact resistance is: the weight of the falling hammer is 1.5kg, and it is not damaged at an impact height of 1600mm. 4. Excellent temperature resistance. The service temperature of ordinary fiberglass sand pipes is generally -40-70 ℃. If temperature resistant resin is used, fiberglass sand pipes can operate for a long time under high temperature conditions of 120 ℃ and maintain good mechanical properties. 5. Small specific gravity, light weight, convenient transportation and installation. The specific gravity is only 1/4-1/5 of steel and cast iron pipes, and 2/3 of concrete. The weight of the pipeline is approximately 1/4 of that of ductile iron pipes of the same specification and length, and 1/10 of that of concrete pipes. Therefore, it is easy to load and unload, and easy to transport and install. 6. Fiberglass reinforced plastic props have excellent wear resistance. Experiments have shown that water containing a large amount of mud and sand can be loaded into the pipe for comparative testing of rotational wear effects. After 3 million rotations, the wear depth of the inner wall of the tested pipe is as follows: the steel pipe coated with tar and porcelain oil is 0.53mm; The steel pipe subject to Case-hardening treatment is 0.48mm; The diameter of fiberglass pipes is 0.21mm, which indicates that the wear resistance of fiberglass pipes is very excellent. If modification additives are added to the resin, the wear resistance of fiberglass pipes can be improved exponentially. 7. The length of pipelines with few interfaces and high installation efficiency is generally 12m/piece (special length pipelines can also be produced according to customer requirements). A single pipeline is long and has fewer interfaces, which accelerates installation speed, reduces failure probability, and improves the installation quality of the entire pipeline. 8. The interface design is scientific, and the leak free interface is sealed with a socket type double "O" type sealing ring. The interface can be installed while undergoing hydraulic testing, ensuring the sealing of the interface and ensuring that the overall pressure test of the pipeline passes at once. 9. Low maintenance costs. Due to the aforementioned properties of corrosion resistance, wear resistance, frost resistance, and stain resistance, fiberglass pipes do not require measures and maintenance such as rust prevention, stain prevention, insulation, and insulation for the project. There is no need for barrier protection for buried pipes, which can save engineering maintenance costs. 10. Health and safety can be achieved by selecting food grade unsaturated polyester resin as the inner lining layer, and fiberglass reinforced plastic sand pipes can meet the requirements of GB 5749 "Sanitary Standards for Drinking Water". 11. The design service life of fiberglass sand pipes with long service life, safety and reliability is based on 50 years, which is twice that of steel pipes and concrete pipes. For highly corrosive media, their service life is much longer than that of steel pipes, etc. 12. Flexible design and strong product adaptability can produce products with various specifications, pressure levels, stiffness levels, or other special performance by changing the design according to various special user requirements, with a wide range of applications. 2、 The molding process of fiberglass sand filled pipes is produced using a microcomputer controlled fiber winding process, using excellent unsaturated polyester resin as the matrix, alkali free glass fiber yarn and its products as the reinforcing material * * quartz sand as the aggregate, and is made through microcomputer controlled winding (sand filling) equipment. All pipes produced by our company are formed using the wet sand inclusion process, which has the characteristics of uniform resin mixing in the sand layer, excellent structural integrity, and stable product quality.
