What is a fiberglass reinforced sand pipe? What are its application advantages?
Release time:
2022/09/05
Fiberglass reinforced sand pipes are a new type of composite material made from resin as the matrix material, fiberglass and its products as the reinforcing material, and quartz sand as the filling material. They have excellent corrosion resistance, hydraulic characteristics, lightweight and high strength, large flow capacity, easy installation, short construction period, and low overall investment, making them an ideal choice for chemical, drainage, and pipeline engineering.
Glass fiber reinforced sand pipeIt is a new type of composite material made of resin as the matrix material, glass fiber and its products as the reinforcement material, and quartz sand as the filler material. It has excellent corrosion resistance, hydraulic characteristics, lightweight and high strength, large flow capacity, convenient installation, short construction period, and low overall investment, making it an ideal choice for chemical, drainage, and pipeline engineering.
1. Excellent corrosion resistance. The glass fiber reinforced sand pipe products are made of highly corrosion-resistant resin, which has excellent mechanical properties and processing characteristics, and can be eroded by most untreated acids, alkalis, saltwater sewage, corrosive soil or groundwater, and many chemicals.
2. Good heat and cold resistance.Glass fiber reinforced sand pipeIt still has good toughness and high strength at -30°, can be used for a long time at -50 to 80°, and specially formulated resins can also be used at 110°.
3. Good wear resistance. The wear resistance of glass fiber reinforced sand pipes is very good. Tests have shown that when water containing a large amount of sediment is placed in the pipe for rotational wear comparison tests, after 300,000 revolutions, the wear depth of the inner wall of the pipes is as follows: steel pipes coated with tar and porcelain oil are 0.53mm, steel pipes with surface hardening treatment are 0.48mm, and glass fiber reinforced pipes are 0.21mm, indicating that glass fiber reinforced pipes have strong wear resistance.
4. Small specific gravity and lightweight. The specific gravity of glass fiber reinforced sand pipes produced by fiber winding is 1.65-2.0, only 1/4 of that of steel, but its circumferential tensile strength is 180-300MPa, and axial tensile strength is 60-150MPa, which is close to that of alloy steel. Therefore, its specific strength is 2-3 times that of alloy steel, allowing for the design of various types of pipes to meet the requirements of withstanding internal and external pressure according to user needs.
5. Good mechanical properties and excellent thermal insulation. The tensile strength of the pipe material is lower than that of steel but higher than that of ductile iron pipes and concrete pipes, while its specific strength is about 3 times that of steel pipes, 10 times that of ductile iron pipes, and 25 times that of concrete pipes. In addition, its thermal conductivity is only 1% of that of steel pipes, with excellent insulation performance, making it suitable for power transmission, densely populated telecommunication lines, and lightning-prone areas.
6. Excellent hydraulic performance and energy saving.Glass fiber reinforced sand pipeThe inner surface is smooth, suitable for large-diameter water supply pipelines. It has a smaller friction coefficient and good hydraulic fluid characteristics, and the larger the diameter, the more obvious its advantages. Conversely, under the same flow conditions, smaller diameter glass fiber reinforced pipes can be used in projects, reducing one-time engineering investment. Compared with other pipes in the water supply process, glass fiber reinforced sand pipes can significantly reduce head loss, saving pump power and energy.
7. Long service life, safe and reliable. The design safety factor of glass fiber reinforced sand pipes is high. According to laboratory simulation test data, the service life for drainage use can reach over 50 years, which is twice that of steel pipes and concrete pipes. For corrosive media, its service life is much longer than that of steel pipes.Glass fiber reinforced sand pipe8. Flexible design and strong product adaptability.
Products can be made in various specifications, pressure ratings, stiffness ratings, or other special performance products by changing the design according to various special user requirements, with a wide range of applications.Glass fiber reinforced sand pipe可以根据用户的各种特殊使用要求，通过改变设计，制成各种规格、压力等级、刚度等级或其他特殊性能的产品，应用范围广泛。
