Expanded Clay Aggregate (ECA), Thermal Insulation of Pipelin

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
