Fiberglass FRP Pipe Fiberglass Process Pipeline

Features of FRP sand pipe 1. Lightweight and high strength: the specific gravity is 1.*5~2.0. For the unit length weight of the same pipe diameter, only 1/3 of the carbon steel, 1/5 of the FRP pipe, and 1/*0 of the prestressed concrete pipe. This reduces the cost of hoisting and increases the installation speed during construction. .
2. Good hydraulic characteristics: This characteristic is particularly prominent in the field of water supply and drainage, with a relatively smooth inner surface, so its hydraulic characteristics are good.

(1) The pumping cost of the pipe network can be saved. For cast iron pipes of the same caliber, FRP can save *0%**0% of pumping costs.

(2) Reduce the pipe diameter size. For the same flow rate, using sand-wound FRP pipes, the pipe diameter can be reduced by ****5%, thereby saving investment costs.

(3) Shorten the pumping time, especially suitable for concentrated water or intermittent water, saving 1/3 of the pumping time and cost.

(4) The FRP pipe does not scale for long-term water delivery and does not need to be cleaned, so that the water quality is not subject to secondary pollution, and it is suitable for transporting drinking water.

3. Good corrosion resistance: The FRP sand pipe has excellent corrosion resistance, which reduces the cost of corrosion and prolongs the service life; at the same time, because it does not rust, the water quality is not subject to secondary pollution. It can also be used to transport sewage, mud, sea water and other media.

4. Pressure resistance: design and manufacture pipelines and fittings according to the pressure required by the process, and conduct a hydraulic test at 1.5 times the pressure required by the process.

5. The interface has good airtightness, no leakage, no breakage, and increases the safety and reliability of water supply.

6. It is non-toxic and can be used to transport drinking water.

The main application of FRP sand pipes: drinking water transportation trunk pipes and water distribution pipes, sewage pipes, rainwater pipes, agricultural irrigation pipes

2. Application

◆ Drinking water transportation trunk pipes and water distribution pipes

◆ Sewage pipes, rainwater pipes

◆ Agricultural irrigation pipe

Three, the main molding process

Controlled by the computer, the inner lining is made on the core mold according to the same process as the fiber-wound fiberglass steel pipe. After gelling, the structural layer is wound according to the designed line type and thickness, and the mortar mixed with quartz sand and resin is wound on the structure. In the layer, the outer protective layer is finally wound.

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