Double Containment Tank

Bulk chemical storage and containment has been a key concern across industries. Chemicals in any form can be harmful, especially the toxic ones. Earlier they were stored in concrete tanks. Double wall containment tanks are specially designed for storing hazardous chemicals or environment-sensitive materials that offer an extra layer of safety. Double wall storage tanks are designed as a tank within a tank which helps prevent spills and leaks, and hence ensures the safety of workers and the environment. A double wall prevents spilling of chemicals that may happen due to the reaction of chemicals with the inner tank lining.

Role of Double Wall Storage Tank in Enhancing Safety and Containment

Here’s how double wall storage tanks help in safe storage of chemicals and abrasive fluids.

  • They are a great alternative to concrete tanks that are not only expensive but need special coating to store abrasive chemicals.
  • The inner tank covering overlaps with the sidewalls of the outer tank to prevent anything from the external environment to enter inside. This prevents contamination.
  • Also, the inside chemicals, oils, and so on cannot come out because of the double wall protection.
  • Leakage issue if any can be quickly detected by observing the interstitial space between the two walls. In case of such as issue, the outer wall still acts as a barrier for the fluid to leak into the outside environment.
  • This forms a safety layer and protects the personnel working in the area from spilling of hazardous chemicals.
  • These tanks also prevent wastage and the effort required to clean up the area after any such spillage. This also saves cost and time.

FAQs on Our Double Wall Storage Tanks

  • Are double wall tanks required by law?

Yes, in many industries dealing with hazardous materials or where groundwater contamination is a concern, double wall tanks are mandated by environmental protection regulations. Manufacturers need to ensure compliance when making these tanks for specific applications such as hazardous chemicals, food, and so on. Industry standards vary based on local, state, or federal laws.

  • What kind of maintenance do double wall tanks require?

It is necessary to check for signs of wear, corrosion, and leaks. Periodically monitor the interstitial space for leaks and ensure it is clean. Maintenance frequency depends on the stored substance and environmental conditions.

  • How do you detect leaks in a double wall tank?

Leak detection in double wall tanks can be conducted through visual checks, manual testing of the interstitial space, or using automated leak detection systems that alert operators in case of a leak.

  • What happens if the outer tank of a double wall tank fails?

If the inner wall leaks, you have the outer wall for protection. While the outer tank's failure is less common due to its protective role and less exposure to aggressive substances, such an event would require immediate action to prevent environmental damage. Ensure you have emergency response plans and secondary containment strategies in place.

  • Can double wall tanks be customized?

Yes, double wall tanks can be customized in terms of size, shape, material, and additional features like heating or cooling systems, depending on the specific needs of the application.

  • What are the cost implications of opting for a double wall tank?

Double wall tanks are generally more expensive than single wall tanks as they have a complex design and construction. However, the long-term benefits of reduced environmental risk and complying with regulations does outweigh the initial investment.
