Fiberglass Tank Inspections
& Maintenance Services

American Fiberglass Tank's field crews and customer service engineers have performed thousands of field inspections and surveys to evaluate the shell integrity and corrosion coat condition of fiberglass vessels used for processing and storage in a multitude of industries. From potable and deionized water to caustic and acidic chemical solutions to food processing, AFTR knows the methodologies to determine the condition of your composite tanks.

Even though many of the service requests AFTR gets are related to apparent problems or elective changes to vessels, fiberglass/composite tank inspection is an integral part of a facility's preventive maintenance program. Because of the unique materials and components used to create these tanks, containment breach can begin long before it is apparent that there is a problem. Surveying the interior corrosion coat, internal body and exterior shell of a fiberglass tank, and the nozzles and other incorporated interfaces, is fundamental in a comprehensive inspection survey. AFTR inspection personnel include our Customer Support Engineers who create and direct the inspection protocols, and work with our crews.

Fiberglass Tank Testing Methods

A hydrostatic test alone just reveals a vessel's ability to contain the liquid product at that exact moment in time. An inspection, employing such industry techniques as interior/exterior visual and instrument inspections to reveal spidering, disbondment, abrasion wear, emulsification, Barcol hardness, floor stress cracking, shell distortion and ultraviolet degradation, is an integral part of an overall survey. A fiberglass tank may pass a hydrostatic test today, but that doesn't necessarily mean it will pass three months from now.

AFTR employs Ultrasonic, Laser and High Intensity Backlight testing methods to help determine not just what the surfaces show, but what is going on in the structural body of the tank including capillary migration of liquid product under the corrosion coat. Detecting such problems early makes repairs simpler and can add many years of useful service life to a fiberglass tank.

At AFTR we believe the best surprise is no surprise at all.
