Product features：
Corrosion-resistant
•Long, effective service-life materials
•No need for linings, coatings, cathodic protection, wraps or other forms of corrosion protection
•Low maintenance costs
•Hydraulic characteristics essentially constant over time
Product advantages：
FRP pipes resist acid, alkali, salt, sea water, untreated sewage, corrosive soil or groundwater and many chemical fluids. Longer service life than traditional pipe, its designed service life is one. Generally more than 50 years. For the glass fiber reinforced plastic pipeline, more is in the municipal, urban transmission and distribution network application, because it has non-toxic, rust-free, tasteless, no secondary pollution to water quality, no corrosion, service life greatly extended, easy installation and other advantages, so it is welcomed by the water supply and drainage industry.
The surface of unsaturated polyester resin is clean and smooth, and will not be adhered by Marine or sewage shellfish, fungi and other microorganisms, resulting in increased roughness; Reduce over-water section and increase maintenance cost. FRP pipe without these pollution, long-term use of clean as before. At the same time because of its smooth inner wall, and has excellent corrosion resistance, will not produce scale and microbial breeding, effectively ensure the water quality, maintain the stability of water resistance. However, the traditional pipe also has the phenomenon of increasing water resistance and surface scaling in the future.
Product application：
Sewage treatment system construction project:Because of its good corrosion resistance and convenient construction conditions, GRP pipes is very suitable for sewage treatment system pipe material.Under the condition of -30℃, it still has good toughness and high strength, and can be used in the range of -50℃-8 ℃ for a long time. The resin with special formula can also work at the temperature above 11O℃.
