Cardox is the answer to removing solid material that is blocking storage vessels. Developed for use in gaseous coals seams, it utilises a release of inert carbon dioxide which eliminates risk of ignition.
The system consists of a high strength reusable steel tube. A special safety chemical heating is sealed within the gas tight tube. The safety heating receives a small electrical charge expanding the liquid CO2 to its gas form. A powerful heaving force from the expanded CO2 of up to 39,000 psi (3000 bar) breaks through the material it has been placed into without damage to vessel walls.
