Vertical Storage Tanks

Molded In Full Drain Outlet - Patent Pending

Assmann Corporation of America offers an FDO (Full Drain Outlet) outlet assembly. This outlet provides the ability to fully drain your tank without the need for mechanically installed nozzles. The full drain assembly should be utilized where heavy solids or salts can accumulate in the bottom of the tank thus creating difficult maintenance work. This assembly virtually eliminates the need for confined space entry

The assembly utilizes a metallic molded in insert. This insert is available in 316 Stainless steel, Titanium and Hastelloy C-276. These material variations allow us to store virtually any chemical in our tank.

Also unique about the FDO assembly is the fully re-placeable polyethylene flange adapter. The adapter can be removed so that the tank can be installed on a flat surface without concrete pad. This also provides the ability to replace the flange in the event of chemical or mechanical damage without having to replace the entire vessel

Assmann’s Full Drain Outlet connection is available in two configurations providing the ability to configure the tank for ease installation and lower maintenance costs.

FDO Complete: This complete assembly comes with the “molded-in” full drain connection, polyethylene flange adapter, butterfly valve and flexible expansion joint. This assembly will be ready for installation.
