Fiberglass, Carbon Fiber & Other Composite Tank Repairs 

Fixing Permeation At Piping Penetration Point

Fiberglass reinforced plastic (FRP) and other composite storage tanks have proven themselves valuable components for the fuel, water and chemical processing industries.  With specialized gel coats on the interior of some vessels, many corrosive products can be safely contained and controlled.  When these tanks are manufactured the primary shell is produced first, and then piping and other protrusions through the composite walls are added.  To reinforce these added holes in the vessel's laminated shell structure, these areas are built up with resin and fiber.   Unfortunately, these " flanges" often are the first areas to breach containment as these tanks age. 

AmTech can repair these areas and recoat the interior surface of tanks to extend their useful service life.  In most cases the overall structural integrity of a composite tank is still intact and offers an ideal substrate to work with.  Routine periodic inspection of all composite tanks is recommended and potential major problems can usually be avoided by maintenance programs designed to keep the interior top layers of reinforced plastic composite functional.  Your AmTech Tank representative can advise you on setting up an inspection program at your facility.

Sodium Hypochlorite is one of the most aggressive chemical environments handled in Fiberglass Reinforced Plastic (FRP) vessels. Choice of resin, cure system, surfacing veil materials, and laminate construction details are critical elements that determine a tanks service life.  These two pictures represent tanks at a water department treatment plant that have containment failure and are in need of repairs.
