Wide application of fiberglass tube in major construction projects


Fiberglass tube is a non-metallic pipe with lightweight, high strength, and corrosion resistance. It is glass fiber with a resin-based weight that is wound layer by layer on a rotating core mold according to the process requirements, and the quartz sand is evenly spread between the fibers as a sand layer at a long distance. The pipe wall structure is reasonable and advanced, which can give full play to the role of the material. Under the premise of meeting the strength of use, it improves the rigidity and ensures the stability and reliability of the product. FRP sand pipe is accepted by the majority of users due to its excellent chemical resistance, lightweight and high strength, no scaling, strong shock resistance, long service life compared with ordinary steel pipe, low comprehensive cost, quick installation, safety and reliability, etc.

9 commonly used fiberglass tube classification:

(1) FRP desulfurization pipeline;

(2) FRP sand pipe;

(3) FRP pressure pipeline;

(4) FRP cable protection tube;

(5) FRP water pipeline;

(6) FRP insulation pipes;

(7) FRP ventilation ducts;

(8) FRP sewage pipeline;

(9) FRP pipe jacking;

  1. Strong corrosion resistance

FRP sand pipes are resistant to acid, alkali, and corrosive soil erosion, and can transport groundwater, seawater, factory sewage, and highly corrosive liquids. According to the transmission medium, the corresponding corrosion-resistant materials are selected to manufacture special pipes. The sand-incorporated pipes can maintain all the characteristics of the original FRP products (lightweight, high strength, corrosion resistance, insulation, heat insulation, and design).

  1. Good wear resistance

FRP sand pipes have good wear resistance. Tests show that water slurry containing a large amount of sand and stones is put into pipes of different materials, and the pipes are rotated 10,000 revolutions.

  1. Heat resistance, frost resistance, and strong temperature adaptability.

FRP sand pipes can operate normally at temperatures of -40°C to 80°C, and pipes with special resin ratios can work at high temperatures up to 110°C, and the pipes will not crack under freezing media.

  1. Small fluid negative force

The inner wall of FRP sand pipe is smooth, with low resistance, roughness coefficient is 0.0084, negative force coefficient is about 1/2 of steel pipe, 1/4 of cement pipe, fluid pressure head loss is small, and it can ensure that larger diameter can be transported with a smaller diameter. flow. Under normal circumstances, sand pipes are one grade lower than cast iron pipes and cement pipes. If pipes with the same inner diameter are used, the power and energy of the pump can be saved by 1/3.

  1. High mechanical strength

The FRP sand pipe has excellent water pressure resistance, external pressure resistance, and impact resistance. It can meet the buried conditions of different geological conditions, and can design and manufacture pipelines and pipe fittings according to the pressure required by customers.

  1. Maintain good water quality

The FRP sand pipe is a non-toxic product, and the drinking water delivered annually can maintain long-term water quality and sanitation.

  1. Lightweight and easy to install

FRP sand pipe has a small proportion, 1/4 of steel pipe and 1/10 of cement pipe. It can be loaded and unloaded every year. The installation cost is low. The sand pipe can be up to 12 meters in length. There are few installation joints and other pipelines are complicated to open. Welding, anti-corrosion treatment, and shadow protection do not require special equipment to ensure the quality of the project.
