Abstract (en)

[origin: EP0269586A2] The invention provides for the use of a liner (6) of flexible, elastic plastics material unattackable by the liquid material to be contained in the tank (1). The plastics liner (6) is inserted into the tank through the manhole (5) or possibly through a connection if sufficiently large. The liner (6) adapts to the inner shape of the tank (1) by virtue of the flexibility and elasticity of the material of which is manufactured. The liner (6) is kept substantially adhering to the inner walls of the tank (1) by flexible hoop elements (7) which are applied to the interior of the liner (6) after it has been inserted into the tank (1), or by pressurisable tubes which are preformed in said liner (6) and are pressurised after the liner (6) has been inserted into the tank (1). In this latter case, a double wall liner can be provided, and the interspace pressurised to monitor any loss of seal. The tubes can also be filled with expanded synthetic material.
