The design service life of fiberglass storage tanks is generally 15 to 20 years. Under the conditions of reasonable selection, standardized installation and maintenance, some high-quality products can be used for more than 25 years. The actual life span is affected by many factors, as follows:: Materials and workmanship: Storage tanks using high-performance vinyl ester resin and microcomputer-controlled winding process have stronger corrosion resistance and structural stability, and have a service life of more than 20 years. storage media: Long-term contact with highly corrosive media (such as hydrochloric acid, sulfuric acid) will accelerate resin aging and affect its service life. For example, the actual life of a fiberglass storage tank containing 15% hydrochloric acid can reach 15 years. Usage environment: When used in the open air, UV rays will cause the resin to degrade, and an anti-UV coating needs to be added to extend its life. Large temperature difference changes can easily cause thermal expansion and contraction fatigue and accelerate structural damage. operating instructions: Keep the exhaust hole clear to avoid negative pressure forming during pumping, causing the tank to collapse. Avoid frequent movement or collision to prevent stress damage to the structural layer. It is not advisable to change the storage medium type to prevent the anti-corrosion layer of the lining from being broken down. In addition, due to strict quality control, the overall service life of the integrally wound storage tanks produced by regular manufacturers is generally better than that of hand-paste products, which can reach more than 15 years.
