Underground LPG tanks

The underground tanks are the ideal solution for locations where its foundation can be dependent on the other factors e.g. intervention in the environment, the site development plan or small area of a plot or aesthetic considerations. Assembly of such tank requires the execution of earth works and commissioning by the inspection of the Office of Technical Inspection before burying of the tank. In a case of the underground tank the distances kept from the residential building and plot boundaries are slightly smaller than in a case of aboveground tanks. During the planning of assembly of the underground tank, the Project Owner must pay attention to the level of ground waters because in a case of the high level of the ground waters the tank may be only partially buried and part of the tank extending above the ground should be side filled with a layer of soil.

Offered capacities of Defro underground tanks [L]: 2700, 4850 and 6400 are covered with the epoxy coating with high resistance to water, flammable liquids and many chemicals. The applied paint is resistant to biogas and natural gases and root ingress ensuring ideal protection of the tank against external impacts. Coating tightness is tested for electric breakdown with 14 kV. Underground tanks are equipped with an inspection chamber with fixtures and valves, which cover is located on the ground surface.
