High temperature storage tank bases

Hot tank bottom installation

Thermal insulation tank base solutions for tanks operating at above ambient temperatures. Our tank base systems provide adequate compressive strength to support the tank and its contents as well as limit heat transfer and provide mechanical, moisture and corrosion resistance so that process control is assured and energy costs are kept at a minimum.

Storage tanks are used to hold a variety of organic liquids or gases including raw materials, intermediates, final products or usable byproducts. Large amounts of energy are wasted due to uninsulated tank bases. 

Without a reliable insulation system, storage tanks can lose energy, money, and put employees at risk. The growing worldwide demand for chemical products along with their proper storage and handling, makes energy efficiency and safety of storage tanks even more important.

A great way to save energy, lower maintenance costs, and improve worker safety around hot storage tanks is by installing an insulation system on the base. With hot storage tanks, tank walls and roofs are often viewed as the largest sources of energy loss; however, unless the tank is filled, the biggest source of energy loss is the bottom of the hot storage tank. This is because the hot liquid in the tank will be in 100% contact with the base. The base in this case becomes the most susceptible area for heat transfer and energy loss.  It is imperative, therefore, to have a good thermal insulation system installed at the tank base to reduce these losses.

A FOAMGLAS® tank base insulation system will prevent energy losses and ensure tanks are operating in the most efficient way. The total payback period of the investment in a FOAMGLAS® tank base insulation system, will range from months to just a couple of years depending on the storage temperature of the contained liquid.

 

Our high load bearing tank base system, can deliver a high compressive strength without any compression.  These systems provide adequate compressive strength suited for your tank design. Insufficient compressive strength in high-load-bearing situations can lead to settlement and loss of thermal performance. This in turn may result in viscosity increase or product solidification or even catastrophic failure of the tank.

Our insulation systems also protect the structural concrete base material against high temperatures, which means that the reinforced concrete foundation is protected from exposure to temperatures which might lead to structural failure in the foundation.

The impermeable closed cell nature of FOAMGLAS® insulation helps prevent ingress of moisture and possible corrosion under insulation (CUI) dangers that could accelerate the deterioration of your storage tanks.  

 

Typical Configuration

for High Temperature Tank Applications:

  • Single or multiple layer system of high load bearing (HLB) FOAMGLAS® insulation
  • Interleaving layer
  • Layer of sand as levelling and pressure distribution layer

The importance of insulating hot storage tank bases
With rising energy costs, the ever-growing issue of CUI and focus on overall safety, it has become cost-effective to install a thermal insulation system underneath hot storage tanks. A well designed and installed thermal tank base insulation system will result in energy savings, increased worker safety, longer tank life and a relatively short payback period.

Compressive strength performance in Industrial Insulation
FOAMGLAS® HLB insulation’s combination of high compressive strength and superior insulation properties with a stable and a non-deteriorating insulation efficiency, helps ensure a constant thermal performance that remains unchanged over time. This has made it one of the preferred materials by tank builders across the world for decades.

The importance of dimensional stability and its influence on the performance of an insulation material
Insulation performance and system integrity is directly related to the dimensional stability of the insulating material. Poor dimensional stability can cause swelling, expansion, shrinkage and buckling of the insulation. This behavior can eventually lead to thermal bridges between insulation and equipment, coating/waterproofing breaches, and, most critically, unpredictable insulation performance.
