What are the Advantages of FRP Tanks?

Feb. 26, 2020

Fiberglass Tank is a kind of glass fiber reinforced plastic products. It is a new type of composite material which is mainly made of glass fiber as the reinforcing agent and resin as the binder and is wound by a microcomputer controlled machine. FRP storage tank has anti-corrosion, high strength, light weight and long life. Because it also has the characteristics of flexible design and strong processability, it can be flexibly designed and used in different industries such as: chemical, environmental protection, food, pharmaceutical In the industry, carbon steel and stainless steel are gradually being replaced. According to the used (storage or transportation) medium, epoxy furan resin, modified or polyester resin, and phenolic resin are selected as the binder, and the resin content is a corrosion-resistant inner lining layer, an anti-seepage layer, a fiber winding reinforcement layer and an external surface protection Layer composition.

FRP tank characteristics:


(1) Lightweight and high strength

The relative density is between 1.5 and 2.0, only 1/4 to 1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels, and other products that need to reduce their weight. The tensile, flexural and compressive strength of some epoxy FRP can reach more than 400Mpa.


(2) Good corrosion resistance

FRP is a good anti-corrosive material, and it is relatively resistant to the atmosphere, water, and common concentrations of acids, alkalis, salts, and various oils and solvents. It has been applied to all aspects of chemical anticorrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.


(3) Good electrical performance

Is an excellent insulating material used to make insulators. It can still protect good dielectric properties at high frequencies. Microwave transmission is good and has been widely used in radomes.


(4) Good thermal performance

FRP has low thermal conductivity, 1.25 ~ 1.67kJ / (m · h · K) at room temperature, only 1/100 ~ 1/1000 of metal, which is an excellent thermal insulation material. It is an ideal thermal protection and anti-ablation material under transient ultra-high temperature conditions, which can protect the spacecraft from high-speed airflow above 2000 ℃.


(5) Good designability

① Various structural products can be flexibly designed according to needs to meet the requirements of use, which can make the product have a good integrity.

② Materials can be fully selected to meet the performance of the product. For example, it can be designed to be resistant to corrosion, instantaneous high temperature, particularly high strength in a certain direction of the product, good dielectric properties, etc.


(6) Excellent processability

① The molding process can be flexibly selected according to the shape, technical requirements, use and quantity of the product.

② The process is simple and can be molded at one time, and the economic effect is outstanding. Especially for products with complex shapes and a small number of products that are not easy to form, its technological superiority is more prominent.


Due to the flexibility of FRP tank design and excellent tank wall structural performance, fiber-reinforced FRP can change the resin system or reinforcement material to high-speed FRP tanks and non-standard physical and chemical properties to meet the needs of different media and working conditions. Through the structure layer thickness, winding angle and wall thickness structure and design to adjust the bearing capacity of the tank body, made of FRP storage tanks and non-standard devices with different pressure levels or some special properties, which is not an isotropic metal material compared to.


The above are the advantages of FRP tanks introduced by Long Life Fiberglass Storage Tank Manufacturer.
