Introduction of FRP storage tanks

FRP storage tank is a kind of FRP products, it is mainly a new type of composite material made of glass fiber as reinforcing agent and resin as binder through microcomputer-controlled machine winding. FRP storage tanks are corrosion-resistant, high-strength, light-weight, and have a long service life. Because of their flexible design and strong manufacturability, they can be flexibly designed and used in different industries, such as: chemical industry, environmental protection, food, pharmaceuticals, etc. In the industry, it is gradually replacing carbon steel and stainless steel in most market areas.

FRP storage tanks can be divided into vertical storage tanks, horizontal storage tanks, FRP tanks, chemical storage tanks, anti-corrosion storage tanks, hydrochloric acid storage tanks, sulfuric acid storage tanks, food tanks, fermentation tanks, transportation storage tanks, storage tanks, glue tanks , chemical tank, pressure storage tank, soy sauce tank, nitric acid storage tank, etc.

FRP storage tank features:

(1) Lightweight and high strength

The relative density is between 1.5 and 2.0, which is only 1/4 to 1/5 of that 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 that of high-grade alloy steel. Therefore, it has excellent results in aviation, rockets, spacecraft, high-pressure vessels and other applications that require weight reduction. The tensile, flexural and compressive strength of some epoxy FRP can reach more than 400Mpa.

(2) Good corrosion resistance

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

(3) Good electrical performance

It is an excellent insulating material and is used to make insulators. It still protects good dielectric properties at high frequencies. It has good microwave permeability and has been widely used in radomes.

(4) Good thermal performance

FRP has low thermal conductivity, which is 1.25~1.67kJ/(m·h·K) at room temperature, which is only 1/100~1/1000 of that of metal. It is an excellent thermal insulation material. In the case of instantaneous ultra-high temperature, it is an ideal thermal protection and ablation resistant material, which can protect the spacecraft from the erosion of high-speed airflow above 2000 °C.

(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.

②The material can be fully selected to meet the performance of the product, such as: corrosion resistance, instantaneous high temperature resistance, special high strength in a certain direction of the product, good dielectric properties, etc. can be designed.

(6) Excellent craftsmanship

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

② The process is simple, it can be formed at one time, and the economic effect is outstanding, especially for products with complex shapes and small quantities that are difficult to form, it highlights its technological superiority.

Due to the flexibility of FRP storage tank design and the excellent structural performance of the tank wall, fiber wound FRP can change the physical and chemical properties of high-speed FRP storage tanks and non-standard devices by changing the resin system or reinforcing materials to meet the needs of different media and working conditions. The bearing capacity of the tank is adjusted through the structure and design of the thickness of the structural layer, the winding angle and the wall thickness, and the FRP storage tanks and non-standard devices with different pressure levels or some special properties are made. compared.
