Structural Base Repair of TNK Floor in FRP: An Analysis of the Leakage Phenomenon in Storage Tanks
Introduction
FRP (Fiberglass Reinforced) storage tanks are widely used in various industries due to their corrosion resistance, lightness and ease of manufacturing. However, the structural foundation of the floor of these tanks can leak over time, leading to safety concerns and additional costs.
Leakage Phenomenon
Leaks in the structural base of the floor of FRP tanks can be caused by various factors, such as:
Manufacturing Defects: Imperfections in the construction of the tank, such as cracks or pores in the FRP material, can create leak points.
Material Degradation: Exposure to chemicals, extreme temperatures, or UV rays can deteriorate FRP and make it susceptible to leaks.
Wear and Tear: Movement of tank contents, vibration or physical impact can wear down the floor pan and cause leaks.
Inadequate design: Poor tank design, without adequate consideration of the loads and stresses to which it will be subjected, can increase the probability of leaks.
Consequences of Leaks
Leaks at the bottom of an FRP tank floor can have serious consequences, such as:
Product loss: Tank contents can spill, resulting in economic loss and environmental damage.
Pollution: Spilled product can contaminate soil and groundwater, with a negative impact on the environment and public health.
Safety Risks: Leaks of flammable or toxic products can create risks of fire, explosion or poisoning for people working in the area.
Tank Deterioration: Moisture and leaking chemicals can deteriorate the structure of the tank, reducing its lifespan and increasing maintenance costs.
Structural Base Repair
There are various techniques to repair the structural base of an FRP tank floor, such as:
FRP Patches: A patch of FRP material is applied over the affected area to seal the leak.
Patching: The crack or pore is filled with an epoxy or similar material to seal the leak.
Underlayment Replacement: The damaged floor underlayment is removed and a new one is installed.
Choosing the appropriate repair technique will depend on the severity of the leak, the type of tank, and the available budget.
Leak Prevention
To prevent leaks in the structural base of an FRP tank floor, it is recommended:
D2R has inspectors specialized in periodic inspections: Inspect the tank regularly to detect and repair any damage to the base of the floor.
Use high quality materials: Select high quality FRP materials with the appropriate strength for the specific application.
Follow good manufacturing practices: Ensure that the construction of the tank is carried out following quality norms and standards.
Have a proper design: Hire a qualified engineer to design the tank according to the specific needs of the application.
Conclusion
Leaks in the structural foundation of an FRP tank floor are a common problem that can have serious consequences. Timely repair and implementation of preventive measures are essential to ensure the safety, efficiency and service life of the tank.
