Eight features of FRP antisepsis
Writer:admin    Released:2018-08-31 17:10:27    Type:【L】【M】【S
The anti-corrosion features of FRP are as follows:

Excellent impact resistance:
The strength of GFRP is higher than that of ductile iron pipe and concrete. The specific strength is about 3 times that of steel, 10 times that of ductile iron and 25 times that of concrete.
The weight of the drop hammer is 1.5kg and it is not damaged under the impact height of 1600mm.

Chemical resistance:
Through reasonable selection of raw materials and scientific thickness design, FRP corrosion can be used in the environment of acid, alkali, salt and organic solvent for a long time with good chemical stability.
In particular, the corrosion of GFRP by water is almost zero, and the corrosion resistance is good.
There is no need to apply strict internal and external coating or cathodic protection as metal material piping.

Good insulation performance:
As the product is made of polymer material and reinforced material, it has low thermal conductivity.
Only 1/100 to 1/1000 of metal are excellent insulation materials, which can guarantee the constant temperature operation of water in summer and avoid the breeding of microorganisms.

Small coefficient of thermal expansion:
Because of the small thermal expansion coefficient of glass fiber reinforced plastic (2.0 x 10-5 / ℃), better adhesion in the grassroots.

Easy installation:
Specific gravity is only 2/3 of that of concrete.
So the combined weight is light.
Therefore, easy loading and unloading, easy installation.

Excellent technical performance:
Before solidification forming, different forming methods can be adopted for the mobility of the resin to make the required shape easily.
This feature is most suitable for large, integral and complex equipment construction requirements, according to the environmental conditions can be site construction.

Excellent hydraulic characteristics:
Glass steel tube has a smooth inner surface, and the flow friction coefficient is small.
The roughness coefficient of glass steel tube is only 0.0053 ~ 0.0084, while that of concrete tube is 0.013 ~ 0.014, a difference of 55% ~ 164%.
The pipe diameter can be reduced under the same flow rate and the same available hydraulic conditions, thus saving investment.
Under the condition of equal flow and same pipe diameter, the pump power and energy can be saved more than 20%, the head can be saved, and the operation energy consumption can be reduced.

Excellent physical performance:
Good adhesion, no cracking, no fouling, the water quality will not be polluted by microorganisms in the water or oxidized rust, no secondary pollution, can guarantee the permanent water transport and water cleanliness.
