process TANKS

Tanks used in the metal finishing industry are manufactured from a variety of materials. The material used to construct the tank depends on the chemistry to be used, the temperature of the solution, the physical size of the tank, and the surrounding environment of the tank.

The most economical materials for tank construction are concrete and steel. Unfortunately, both of these materials are highly susceptible to the corrosive environment found in most metal finishing facilities. Specialty coatings and lining materials are available to help extend the service life of a tank in the shop.

Polypropylene tanks are the most widely used in metal finishing industry. Polypropylene provides resistance to most chemistries and has good temperature resistance. Polypropylene is easily machined, can be easily drilled, welded, and bent. This allows for complex geometries to be created.

Other materials that are commonly available are Fiberglass, PVC, and Polyethylene.

For aqueous cleaning tanks, overflow sumps can be constructed to allow for the collection of floating oils. Counterflows can be installed into rinse tanks for water conservation. Tank saddles can be mounted on the flanges of the tank to help position carriers or superstuctures. These tank saddles can be manufactured of polyglass for non-electrified stations and bronze for electrified stations.
