Quality appraisal of fiberglass composite tanks

Fiberglass composite tank is a composite container made of glass fiber reinforced plastic (commonly known as "glass fiber reinforced plastic"). It is widely used in chemical industry, environmental protection, water supply and drainage, textile, food, pharmaceutical, brewing and other industries for its light weight, high strength, corrosion resistance, resistance to chemical media, resistance to rust and good insulation properties. It is used to store and transport various liquids and gases, such as drinking water, wastewater, chemical raw materials, fuel, etc.
In the case of quality appraisal of fiberglass reinforced plastic composite tanks, Zhongke Testing can provide quality appraisal services for fiberglass reinforced plastic composite tanks.

was entrusted by a court to conduct identification and analysis on the reasons why the fiberglass composite tank involved in the case "ruptured during transportation, resulting in serious leakage and large-scale pollution."
quality analysis results: The
quality analysis expert group discussed and conducted a comprehensive quality technical analysis on the relevant information and on-site investigation and inspection of the FRP composite tank involved, and made the following suggestions and conclusions: The welding process of the
FRP composite tank is relatively rough and cannot guarantee safe transportation. The fiberglass composite tank has no anti-corrosion layer.
FRP composite tank product quality appraisal conclusion: The manufacturing process of this FRP composite tank does not meet national standards, and no special anti-corrosion treatment is carried out inside the tank.
