FRP corrosion characteristics

FRP anti-corrosion characteristics are as follows:

Excellent impact resistance:

The strength of FRP is higher than steel and concrete ductile iron, than about three times the strength of steel,fiberglass chopped strand mat ductile iron 10 times, 25 times of concrete; drop weight 1.5kg without damage under the impact height 1600mm.

Chemical resistant:

Reasonable raw material selection and design of scientific thickness, glass steel corrosion in acid, alkali, salt, organic solvent environment, long-term use, has good chemical stability. Especially water glass steel corrosion is almost zero, good corrosion resistance. Like metal material that does not need rigorous internal and external pipeline coating or cathodic protection, in the lifetime of basic need protection.

Good insulation properties:

Since FRP composite products are made of a polymer material and reinforcing material made with low thermal conductivity characteristics; only metal 1/100 to 1/1000, is an excellent insulation material, the summer to ensure constant running water, avoid microbial breeding.

Thermal expansion coefficient:

Because fiberglass thermal expansion coefficient (2.0 × 10-5 / ℃), better adhesion to the substrate.

Lightweight, high strength and ease of installation:

Concrete accounts for only 2/3; so comprehensive in terms of weight compared to the light. Thus, loading and unloading easy, easy to install.

Construction process performance:

FRP molding before curing, the fluidity of the resin can be molded using different methods, and easily processed into the desired shape; this characteristic most suitable for large, complex equipment and structure of the overall construction requirements, according to the environmental situation can be on-site construction .

Hydraulic excellent characteristics:

The inner surface of the glass pipe has a smooth, flow friction coefficient. Glass pipe roughness coefficient of only 0.0053 ~ 0.0084, while concrete pipe is from 0.013 to 0.014, a difference of 55% to 164%. In quite the same flow rate and water conditions can be used can be reduced diameter, thereby saving investment. In quite the same caliber and flow conditions of the pump power and energy savings of more than 20%, saving the head, reducing energy consumption.

Excellent physical properties:

Good adhesion, no cracking, scaling, water will not be rusty microbial contamination or oxidation of water, no secondary pollution, to ensure the permanent cleanliness of water quantity and quality output unchanged.
