Performance Advantages Of Resin Pipes

Jun 20, 2020

Excellent characteristics of glass fiber reinforced plastic resin pipes: corrosion-resistant and non-polluting, resistant to acids, alkalis, salts, seawater, untreated sewage, corrosive soil or groundwater and many chemical fluids erosion. FRP resin pipes have the excellent characteristics of non-toxic, rust-free, odorless, no secondary pollution to water quality and no need of anti-corrosion.

        The FRP resin pipe is anti-fouling and anti-moth. The surface of the FRP resin pipe uses unsaturated polyester resin, so its surface is clean and smooth, and will not be contaminated by microorganisms such as fungi in the ocean or sewage. Water section increases maintenance costs.

        The use temperature of glass fiber reinforced plastic resin: heat and frost resistance, at -30 ℃, it still has good toughness and extremely high strength, can be used for a long time in the range of -50 ℃ -80 ℃, using special formula resin It can work under the temperature above 110℃.


       The performance ratio of FRP resin pipeline to other pipelines: light weight, high strength, easy transportation and installation. The fiberglass resin pipe produced by the fiber winding process has a specific gravity of 1.65-2.0, which is only 1/4 of that of steel, but the circumferential tensile strength of the FRP is 180-300MPa and the axial tensile strength is 60-150MPa. In this way, it can be designed according to the different requirements of users to meet the requirements of various types of pipelines under internal and external pressure. For single-weight glass steel pipes of the same diameter, only 1/2.5 of carbon steel pipes, 1/3.5 of cast iron pipes, and about 1/8 of prestressed reinforced concrete pipes. Therefore, transportation and installation are very convenient, and the cost of lifting is reduced. Increased installation speed.

       FRP resin pipeline has low friction resistance and high conveying capacity. The inner wall of FRP pipe is very smooth, and the roughness and friction resistance are very small. The roughness coefficient is 0.0084, while the concrete pipe is 0.014 and the cast iron pipe is 0.013. Therefore, FRP can significantly reduce the fluid pressure loss along the way and improve the conveying capacity. Therefore, it can bring significant economic benefits: when the conveying capacity is the same, the project can choose a glass fiber reinforced plastic resin pipe with a smaller inner diameter, thereby reducing one-time engineering investment; using the same inner diameter pipeline, the glass fiber reinforced plastic resin pipe can reduce the pressure than other material pipes Head loss, saving pumping costs. In addition, FRP resin pipes can shorten the pumping time and reduce long-term operating costs.

       Insulation of FRP resin pipes: FRP resin pipes have good electrical and thermal insulation, FRP is non-conductor, and the electrical insulation of pipes is particularly excellent. It is most suitable for power transmission, as FRP cable protection pipes, etc., in areas with dense telecommunication lines and multiple mine areas The heat transfer coefficient is very small, and the insulation performance of the pipeline is excellent.

       The fiberglass resin pipeline has good wear resistance, and the water containing a large amount of mud and sand is put into the pipe to conduct a comparative test of the effect of rotating wear. After 3 million rotations, the wear depth of the inner wall of the detection tube is as follows: the steel tube coated with tar and enamel is 0.53mm, the steel tube coated with epoxy resin and tar is 0.52mm, and the steel tube after surface hardening treatment is a glass tube It is 0.21mm. Therefore, FRP has good wear resistance.

       Maintenance cost of glass fiber reinforced plastic resin pipeline: low maintenance cost, glass fiber reinforced plastic pipe due to the above-mentioned corrosion resistance, wear resistance and anti-freezing and anti-fouling
