CISTERN FOR STORING LIQUEFIED PETROLEUM GAS

摘要

The cistern consists of an airtight tank (4) made of sheet steel having on its outer surface a layer of passive anticorrosion sheathing (10) which itself is covered by a layer of hydraulic mortar sheathing (23) which is designed to come in direct contact with the natural soil (13) in the ground without requiring the use of a layer of sand (17) but offering the same possibilities of cathodic protection for the cistern (22) by means of sacrificial anodes (15).
