Thermal insulation solutions for underground vessels operating at below or above ambient temperatures.

Our systems for direct burial provide high compressive strength while limiting heat transfer providing mechanical, moisture and corrosion resistance so that process control is assured and energy costs are kept at a minimum.

The use of underground vessels for the storage of fuels and other liquids has many advantages. These include space considerations, fire safety and protection from the elements. However, unless installed and maintained properly, underground vessels can have the potential for a number of hazards. Possible leaks or damages to the vessel can exist undetected for years and cause severe consequences in terms of overall safety soil pollution.

A lot of underground vessels are made of steel and therefore could be subjected to corrosion as a result of leakages, overfilling or direct contact with ground water. This is one of the reasons why underground vessels should be insulated and ideally with an insulation system that is capable of meeting the mechanical and corrosion resistance requirements of direct burial while providing long-term insulation efficiency. Ignoring these basic considerations may result in problems.

Due to the pressure of the surrounding soil it is required to choose an insulation material that already has a high compressive strength without additional structural protection. This will make sure that the insulation does not compress which could harm the thermal efficiency and overall performance of the system.

A FOAMGLAS® vessel insulation system will protect your underground vessel from possible ingress of any moisture or other liquids which will prevent any corrosion of the tank itself. The system will remain dry and keep its thermal efficiency over time ensuring perfect process control so that the integrity of the content is guaranteed and operating costs are kept at a minimum.

The high compressive strength of FOAMGLAS® insulation makes it an ideal material for direct burial applications because it can easily withstand the earth pressure. The system will not compress and will guarantee the same thermal properties throughout the lifetime of the vessel.

Because it is completely incombustible, it will contribute to the fire safety of the installation. Should a leakage occur, it will not absorb any of the possibly flammable liquids like some other insulation materials do.
