Fiber wrapped fiberglass reinforced plastic (FRP) wrapped pipes are reliable, safe, and economical, mainly used for buried pipes and long-distance pipelines. They have the characteristics of light weight, high strength, corrosion resistance, long service life, and low operating and maintenance costs, which can save a lot of funds for construction projects.

1、 Characteristics

1. Lightweight and high-strength: The specific gravity of fiberglass sand filled pipes is 1.65-2.0. For the unit length weight of the same pipe diameter, it is only 1/3 of carbon steel, 1/5 of cast iron pipe for FRP pipe, and 1/10 of prestressed concrete pipe, which reduces lifting costs and improves installation speed during construction.

2. Good hydraulic characteristics: This characteristic is particularly prominent in the field of water supply and drainage, with good hydraulic characteristics.

(1) It can save the cost of pipeline pumping. (2) Reduce the diameter of the pipe. (3) Shorten pumping time.

(4) FRP pipes can transport water for a long time without scaling and do not require cleaning, ensuring that the water quality is not subject to secondary pollution.

3. Good water and corrosion resistance: Fiberglass wrapped pipes have excellent corrosion resistance, reducing anti-corrosion costs and extending service life; At the same time, due to its non rusting properties, the water quality is not subject to secondary pollution. It can also be used to transport media such as sewage, mud, seawater, etc.

4. Pressure resistance: Design and manufacture pipes and fittings according to the required pressure of the process, and conduct a water pressure test at 1.5 times the required pressure of the process.

5. Good interface sealing, no leakage, no rupture, increasing water supply safety and reliability.

6. Non toxic, can be used for transporting drinking water.

2、 Application

◆ Drinking water transmission main pipeline and distribution pipeline

◆ Sewage and rainwater pipelines

◆ Agricultural irrigation pipes

3、 Main molding process

Under the control of computer, the inner lining is manufactured on the core mold according to the same process as the filament wound FRP pipe. After gel, the structural layer is wound according to the designed line shape and thickness, and the mortar mixed with quartz sand and resin is wound in the structural layer, and finally the external protective layer is wound.

4、 Raw and auxiliary materials: resin, chopped fibers, continuous glass fibers, and quartz sand.
