Process tank cleaning with leak and gas free testing

Franchini S.p.A. Servizi Ecologici operates throughout the country for tank leak tests. In order to have tanks that are always efficient and safe, regular preventive periodic inspections are necessary by means of leak tests, recognised by the authorities in charge, and aimed at monitoring and verifying their structural integrity. Tank leak tests are performed during normal operation activities or following the decommissioning of an underground tank in order to meet regulatory requirements as per Arpa guidelines and municipal hygiene regulations. All our interventions are carried out by highly specialised operators, using equipment and instrumentation compliant with UNICHIM standards, guaranteeing the best results in terms of safety and quality of the service provided and in full compliance with current environmental regulations.

Process Tanks

Process tanks and reservoirs are an integral part of many industrial production plants, which is why their maintenance and cleaning becomes indispensable and necessary to guarantee the efficiency and safety of the plants themselves. Tanks can be horizontal or vertical and contain hazardous substances such as acids and corrosive substances. The physical state of the substance stored in the tank can also vary significantly from one process to another; it can be in a liquid state or sometimes a solid state. For these reasons, maintenance work on tanks, including cleaning, requires intervention planning, specific skills and technical precautions that Franchini S.p.A. Servizi Ecologici is able to offer thanks to the professionalism acquired together with the use of modern equipment and highly prepared and trained personnel. Franchini S.p.A. also provides for the collection, transport and disposal of any residual waste resulting from tank cleaning. Once the cleaning operation has been completed, a Declaration of Tank Cleaning is issued to the customer, in which a qualified technician certifies that all activities performed were carried out in a workmanlike manner and in accordance with current regulations.

Gas free verification

The "gas free" state is the instrumental verification of the actual condition detected, inside a tank or closed confined space, in order to determine the risks related to the composition of the internal atmosphere. By means of calibrated and certified measuring instruments, Franchini S.p.A. Servizi Ecologici is able to assess the potential explosiveness of the reclaimed volume so as to stabilise the atmosphere and make it a safe environment over time even when temperature and pressure vary. The "gas free" verification is required by regulations and certifies the absence of risks linked to the presence of flammable or explosive vapours inside the tank.
