Stainless steel tanks
APRO Industrie provides stainless steel tanks for industry and public services throughout France and internationally. They are suitable for the storage of most liquids.
What is stainless steel?
Stainless steel is an alloy of iron and carbon, containing a minimum of 10.5% chrome. Beyond that content, it naturally forms a protective coating of chrome oxide, which in most cases protects the steel from corrosion and which is spontaneously regenerated if it is damaged mechanically. The addition of other metals can improve the physical properties of these steels (nickel for ductility, or titanium for very high temperature resistance, for example).
Many alloys may therefore be used in industry. The grades most frequently encountered are the alimentary grades 304/304L and 316/316L. These are the grades which we use for the manufacture of stainless steel tanks or accessories (couplings, manhole covers etc.).
Main fields of application
Stainless steel tanks can be used for the storage of most industrial fluids (water, inputs, effluents, etc.). The use of stainless steels for the storage of liquids, does however involve a prior compatibility check. Stainless steels are in fact intolerant of certain chemicals (chlorides for example).
The sealing of stainless steel tanks may be achieved using a suitable mastic sealant. For the storage of potable water in France, an ACS certified sealing membrane is required.
