Updated: Jan 11

Everything You Need to Know about Bulk FRP Tank Repair

Due to its strength, resistance to corrosion, and capacity to handle severe temperatures, fiberglass tanks are a popular option for a range of industrial and commercial applications. Even the most resilient fiberglass tanks, though, will ultimately need to be repaired. Repairing and maintaining bulk fiberglass tanks is our area of expertise at Plastech Services Inc. The sorts of repairs that could be required, the stages involved in the repair process, and advice for maintaining and extending the life of your fiberglass tanks are all covered in detail in this article's complete guide to bulk fiberglass tank repair.

We also understand that many FRP Tanks are purchased and installed at the same time, resulting in bulk repair requests. We've performed bulk FRP tank inspections and repairs for Kuehne Chemical, Pixelle Specialty Solutions, and dozens of other pulp and paper mill and chemical processing facilities

Depending on the kind of damage that has occurred, bulk fiberglass tanks may need a variety of repairs. Among the most typical forms of repairs are:

  • Crack patching: Impact, heat stress, chemical exposure, and other reasons can all lead to cracks in fiberglass tanks. If not fixed, these flaws might compromise the tank's structural integrity and cause leaks.

  • Leak repair: Cracks, damage to the connections or fittings, and other issues can all lead to leaks in fiberglass tanks. If leaks are not quickly fixed, the tank may sustain more damage.

  • Repairing broken nozzles: Nozzles are a crucial part of many fiberglass tanks, but they are susceptible to damage from corrosion, impacts, and other causes. Damaged nozzles should be fixed or replaced as quickly as possible since they might lead to leaks or other issues.

  • Repairing corrosion: Exposure to certain chemicals or other severe situations can cause corrosion in fiberglass tanks. If corrosion is not corrected, it may undermine the tank's structural integrity and cause leaks.

  • Structural Repair: Fiberglass tanks occasionally need to have their structural integrity restored because of deterioration, which may necessitate structural repairs. This might involve fixing the roof, the support structure, or other parts. We've seen cases where tank supports or the structural integrity of the tank, need repairs.

Steps Involved in Bulk Fiberglass Tank Repair

The methods necessary to repair a bulk fiberglass tank will change based on the kind and extent of the damage. However, the following stages are usually included in the repair process:

  1. Inspection: To evaluate the degree of the damage and spot any possible problems, a comprehensive inspection of the tank is the first stage in any bulk fiberglass tank repair.

  2. Surface preparation: The tank's surface has to be ready for repair after the damage has been determined. In order to improve the surface's ability to attach, this usually entails cleaning the region around the damage and roughening it.

  3. Applying the Repair: After preparing the surface, the damaged area is then covered with the repair material. Various methods can be used to accomplish this, depending on the sort of repair being made. For instance, a gel coat can be used to fix cracked nozzles or other surface damage, whereas polyester resin can fix cracks or leaks.

  4. Allow the repair to cure: The repair material must be given time to cure after application. The type of repair material utilized and the environment in which the repair is being made will affect the curing time.

  5. Final examination: The tank must be examined once the repair material has dried to make sure the repair was effective and there are no further problems.

Tips for Maintaining and Prolonging the Life of Your Bulk Fiberglass Tanks

To increase the lifespan of your bulk fiberglass tanks and lessen the need for repairs in addition to standard maintenance, you may do a number of things:

  • Maintenance: To prevent the accumulation of dirt and debris, which can result in corrosion or other damage, regular maintenance and cleaning are required. It is important to use cleaning products and techniques that are appropriate for the specific type of fiberglass tank and the items stored inside.

  • Impact Damage: Collision damage can cause significant damage to fiberglass tanks, thus it's necessary to take precautions to safeguard the tank from impact. We've seen FRP tanks accidentally hit by forklifts or other vehicles, causing significant damage and leading to expensive failures. To protect the tank against impact, this may entail erecting barriers around it or utilizing cushioning or other safeguards.

  • Environment monitoring: The tank's surroundings can have a significant influence on how it is doing. Monitoring variables including temperature, humidity, and chemical exposure is crucial. If necessary, protective measures should be taken to safeguard the tank from adverse circumstances.

  • Keep an eye out for damage: It's crucial to routinely check the tanks for damage, as certain problems might not be immediately obvious. Watch for any cracks, leaks, or other indications of deterioration, and take immediate action to fix them.

  • Properly storing chemicals is essential since some chemicals might eventually harm storage tanks. This is why it's crucial to store chemicals correctly. Utilizing the proper storage techniques and making sure the chemicals are compatible with the tank's material are crucial.

In conclusion, bulk fiberglass tank repair is an important aspect of maintaining industrial operations. At Plastech Services Inc., we specialize in bulk fiberglass tank repair and maintenance. By understanding the types of repairs that may be needed, the steps involved in the repair process, and tips for maintaining and prolonging the life of your fiberglass tanks, you can ensure that your bulk fiberglass tanks are in good working condition and ready to handle whatever industrial needs you may have.
