Fiberglass Reinforced Plastic (FRP)
Tank Inspection

Fiberglass reinforced plastic (FRP) tanks present unique inspection challenges. As fiberglass tanks age, structural defects appear in the layers of fiberglass and resin from which the tanks are built. Common fiberglass tank inspection methods rely on visual inspection to identify cracking or damage to the corrosion barrier, but are unable to provide much insight regarding the fiberglass structure. FRP tank owners often retire their tanks early, at significant expense, because inspectors struggle to provide good estimates of a tank’s remaining life.

TSP performs FRP tank inspection using UltraAnalytix™, a patented method for inspecting fiberglass assets. UltraAnalytix uses ultrasonic flaw detection to gather data about the fiberglass structure of the tank and analyzes the data with powerful software to determine the tank’s condition. The analysis determines the remaining percentage of design strength and estimated remaining service life of the tank.

Advantages of UltraAnalytix™:

  • Can be performed while tanks are in service. No plant or equipment shutdown required.
  • Maintains structural integrity of FRP. Testing is non-destructive and non-intrusive.
  • Finds sub-surface flaws.
  • Generates numerical results for tank integrity and remaining service life.
  • Allows ongoing upgrade of safety factor or structural integrity.
  • Minimizes confined space entry.

Steel Tank Inspection

As steel tanks age, their metal shells naturally corrode. The rate of corrosion depends on many factors including the product stored in the tank, the tank’s exposure to weather, and the integrity of the tank’s coatings or linings. Read more about Steel Tank Inspection ›

Plastic Tank Inspection

Plastic tanks, also known as poly tanks or HDPE tanks, are common in commercial and industrial settings where chemical compatibility or low cost storage are essential. Read more about Plastic Tank Inspection ›
