Glass fiber reinforced plastic sand pipe is suitable for different environments. According to different corrosive environments, different anti-corrosion resins can be selected, mainly including: isophthalic unsaturated polyester resin, vinyl resin, bisphenol A resin, epoxy resin and furan resin, etc. According to specific conditions, bisphenol A resin and furan resin are selected for acidic environment. For alkaline environment, vinyl resin, epoxy resin or furan resin is selected. For solvent-based environment, selection of furan and other resins; when the acid, salt, solvent and other corrosion is not very serious, you can choose the price is relatively low benzene type resin. Through the selection of different resins for the lining layer, FRP pipes can be widely used in acid, alkali, salt, solvent and other working environments, showing good corrosion resistance.

The reinforced glass fiber reinforced plastic sand pipe has the following characteristics.

1, the application of centrifugal casting method Qi high-density non-void tube wall, and to ensure that the glass strengthening part in the outer tube wall of the inner and outer surface of the tube wall is accurate and smooth, no scale, head loss is small, high pipeline strength, pressure up to 2O ~ 24tar;

2. The joint is convenient and the installation is simple. The pipe end is open, which can be cut off at any position on site. The loose collar joint made of chloroprene rubber and glass fiber reinforced plastic is connected, and it can bear longitudinal compression force or tensile force under various conditions;

3. The glass fiber reinforced plastic sand pipe has strong corrosion resistance, and there is no need for anti-corrosion treatment inside and outside the pipe wall. The service life can theoretically exceed 50 years, and there is no electric corrosion problem;

4. Light weight, only 10% of concrete pipe with the same diameter, 20% of metal pipe or asbestos cement pipe;

5, a wide range of applications, can withstand 70 ℃ high temperature, can be used for industrial water and drinking water, can also be used for sewage and corrosive industrial wastewater or seawater, can be installed on the ground or buried in the ground or even under the sea, can be installed in a variety of harsh environmental climate and terrain conditions, the use of good results;

6, the pipeline accessories are complete, can be connected with any other material of the pipeline, in any part of the pipe can be opened.
