FRP site wound tank

Large on-site glass fiber reinforced plastic (GFRP) storage tanks refer to tanks with diameters exceeding 4 meters, which are inconvenient to transport and must be manufactured on-site. The production processes include integral molding and winding processes, capable of manufacturing large storage tanks with diameters up to 25 meters and volumes up to 5000 cubic meters, suitable for various industrial needs. The design and manufacturing of these tanks follow multiple national and industry standards, ensuring full consideration and satisfaction of structural strength stability, corrosion resistance, operational and maintenance requirements, and environmental requirements.

The advantages of large on-site GFRP storage tanks mainly include:

1. Excellent physical properties: GFRP storage tanks have superior physical properties with a specific gravity of only 1.5~1.9 g/cm³, which is 1/4 to 1/5 that of steel, higher than the specific strength of steel, cast iron, and plastic. Additionally, the thermal expansion coefficient of GFRP is similar to that of steel, and its thermal conductivity is only 0.5% that of steel, making it a good insulator for heat and electricity.

2. Strong resistance to chemical corrosion: GFRP storage tanks can resist the erosion of various acids, alkalis, salts, and organic solvents, such as hydrochloric acid, sulfuric acid, nitric acid, formaldehyde, methanol, alcohol, preservatives, sewage, and sodium hypochlorite. This makes them widely used in industries such as chemicals, petroleum, papermaking, food, electronics, and pharmaceuticals.

3. Large design flexibility: GFRP storage tanks have a large design flexibility and can be optimized for internal structure and physical properties according to requirements, especially for the storage of liquid and solid media. This design flexibility allows GFRP storage tanks to adapt to various complex application environments.

4. Long service life and low maintenance cost: GFRP storage tanks have high strength and strong corrosion resistance, a long service life, and relatively low maintenance costs due to their excellent physical and chemical properties.

5. Good environmental effect: GFRP storage tanks have good thermal insulation and insulation properties. Additionally, due to their smooth and flat surface, they are not prone to fouling and are easy to clean, which also has certain advantages in environmental protection.

Large on-site GFRP storage tanks have wide applications in various industries, including but not limited to:

1. Petroleum and chemical industry: GFRP storage tanks are widely used for storing petroleum, natural gas, chemicals, and other liquid or gas media due to their excellent corrosion resistance. These media often have strong corrosivity, and GFRP tanks can effectively resist the erosion of these corrosive media.

2. Food brewing and pharmaceutical fields: In the food brewing and pharmaceutical industries, GFRP storage tanks also play an important role. They are used for storing various chemicals and pharmaceuticals, ensuring the quality and safety of products.

3. Power industry: In the power industry, GFRP storage tanks are mainly used for storing chemical reagents and purifying agents, ensuring the cleanliness and stability of water quality during power generation.

4. Environmental protection field: GFRP storage tanks are also widely used in sewage treatment, garbage pit cleaning, and other applications. They can effectively store and treat harmful substances, reducing environmental pollution.

5. Agriculture and water irrigation: In agriculture and water irrigation fields, GFRP storage tanks are used for storing irrigation water and other agricultural chemicals, improving the efficiency of water resource utilization and the sustainability of agricultural production.

6. Defense projects: In defense projects, GFRP storage tanks are also applied, although specific application scenarios are less mentioned, their lightweight, high strength, and corrosion resistance make them an ideal choice for certain special purposes.

7. Transportation: In the field of long-distance ferries, large GFRP storage tanks are used for storing fuel and other important materials, ensuring the safety and endurance of ships.

8. Aerospace: Although direct evidence is limited, considering the lightweight and high-strength properties of GFRP storage tanks, they are likely to be used in the aerospace field for storing critical materials such as fuel and hydraulic oil.
