Tankki

Tankki is a Finnish noun that denotes a tank or tank-like container. It is used to refer to large vessels that store liquids or gases, spanning household, industrial, and infrastructural contexts. Common meanings include water tanks, fuel tanks, chemical tanks, and underground storage tanks. The term is widely used in everyday Finnish to describe reservoirs and vessels of significant capacity.

In practical usage, tankki often refers to a vehicle’s onboard reservoir, such as a polttoaineen tankki (fuel tank) or other internal tanks for coolant, hydraulics, or ballast. Industrially, storage tanks come in various designs and sizes: above-ground or underground, vertical cylindrical, horizontal, or spherical shapes, and made from materials such as steel, fiberglass, or polyethylene. Typical features include fill necks, vents, manways, level indicators, and sometimes double-walled construction for safety. Design and construction follow applicable national and international standards, with attention to corrosion resistance, leak prevention, and safe handling of contents.

In Finnish terminology for military hardware, the armored fighting vehicle known in English as a tank is usually termed panssarivaunu rather than tankki, though the informal use of tankki may appear in translations or historical discussions. Overall, tankki encompasses a broad range of containers and reservoirs designed to store or transport liquids or gases, both in everyday life and in industrial settings.
