A Brief Analysis of the Factors Influencing the Price of FRP Storage Tanks
Release time:
2019/08/12
Fiberglass storage tanks have corrosion resistance, high strength, light weight, and long service life. Due to their flexible design capabilities and strong processability, they can be designed for use in various industries such as chemical, environmental protection, food, and pharmaceuticals, gradually replacing carbon steel and stainless steel in many market areas. The main factors affecting the price of fiberglass storage tanks include the manufacturing process, materials, performance requirements, and appearance quality. 1. The impact of material selection on the price of fiberglass storage tanks: 1.

Fiberglass storage tanks have corrosion resistance, high strength, light weight, and long service life. Due to their flexible design and strong processability, they can be designed for use in various industries such as chemical, environmental protection, food, and pharmaceuticals, gradually replacing carbon steel and stainless steel in most market areas. The main factors affecting the price of fiberglass storage tanks include the manufacturing process, materials, performance requirements, and appearance quality.
1. The impact of material selection on the price of fiberglass storage tanks.
1. The fiberglass storage tank industry standard recommends using alkali-free glass fiber and its fabrics to manufacture fiberglass storage tanks. Alkali-free glass fiber and its fabrics have good chemical stability, excellent mechanical properties, good resin permeability, and good electrical insulation properties, but their prices are relatively higher than those of other medium-alkali or high-alkali glass fibers and their fabrics, with price differences of over 30% for similar products.
2. Different resin models used in fiberglass storage tanks can cause significant price differences. For example, the price of vinyl resin is multiple times that of bisphenol A resin.1.4.
2. The impact of the lining of fiberglass storage tanks on price.
To meet the requirements for corrosion resistance and impermeability, the lining of fiberglass storage tanks is crucial. With a fixed thickness of the fiberglass storage tank, the thicker the lining layer, the higher the cost; similarly, the higher the resin content in the lining layer, the higher the cost.
3. The impact of the production process of fiberglass storage tanks on price.
1. Fiberglass storage tanks made using spraying technology can achieve a resin content of 95% in the lining layer, providing excellent corrosion and impermeability performance; while those made using hand lay-up have a resin content of about45%.The lower resin content results in a material cost that is nearly50%.The corrosion and impermeability performance is also poorer.
2. Fiberglass storage tanks made using integrated winding molding can achieve a tensile strength of 500MPA; while those made using hand lay-up have a tensile strength of200MPA, with a service life about1/3-1/8, which has a lower cost-performance ratio.
3. Fiberglass storage tanks made using bell jar molds have a round and beautiful shape, with no stress concentration at corners; while those made by splicing have stress concentration at the joints, resulting in a shorter service life, but they are much cheaper as they do not require molds.
4. The impact of the appearance quality of fiberglass storage tanks on price.
After the winding process, the surface of the fiberglass storage tank will not be very smooth. To make the product's surface glossy and free of burrs, it needs to be uniformly polished, and then the corresponding resin is applied. This incurs two costs: one is the cost of polishing equipment and labor, and the other is the material cost of reapplying resin. Additionally, to improve the anti-aging performance of the fiberglass storage tank, UV absorbers are added to the outermost layer of the coating, effectively extending the product's service life.
