Thermal Insulation of Pipelines and Structures

Expanded Clay Aggregate (ECA®) can be used as bedding and insulator media for underground oil and gas pipeline. It helps brings practical and technical advantages as mentioned below:

  • Expanded Clay Aggregate (ECA®) provides a thermal resistance between the pipeline and the ground level
  • It makes oil and gas pipeline easy to lay without the risk of damage and without any need for compaction
  • In case of any maintenance, ECA® is very easy to remove and leakage in any pipe is easy to identify
  • Expanded Clay Aggregate (ECA®) protects pipeline from thrust caused by landslide, seismic event and any sort of vibration
  • Expanded Clay Aggregate (ECA®) also protects pipelines from significant loading
  • Expanded Clay Aggregate (ECA®) helps in elimination and drainage of stagnant water because of its excellent drainage property.


Tanks that are used for storing flammable liquids (oil & gas) are buried using Expanded Clay Aggregate (ECA®) and it helps in reducing the risk of damages or accidents. Based on its properties, ECA® is the perfect material for burying all sorts of tanks carrying oil and gas.

Expanded Clay Aggregate (ECA®) increases the durability of the tank both in acidic and base environments due to its neutral pH.

  • It makes the oil & gas resistant to weather and thaw cycles
  • ECA® makes the tank incombustible and resistant to fire
  • ECA® provides a thermal resistance between the tank and the ground level (with lower heat loss and reduced risk of freezing)
  • ECA® helps in elimination and drainage of stagnant water
