Corrosion resistant housings: tantaline from Amazon Filters

Amazon Filters is a leading supplier of filter housings to a wide range of industries including many where effective filtration of chemical products is critical to their operations. In order to provide enhanced support to companies who have a requirement to filter highly corrosive fluids Amazon Filters is introducing a range of filter housings that have been modified to provide a surface that is composed of pure Tantalum metal. This provides a product that has superior resistance to many corrosive chemicals than nickel alloys such as Hastelloy and a significantly more robust surface finish than coated housings.


The Technology

The use of the Tantaline vapour deposition for protection against chemical attack is already being adopted for a range of process equipment including valves, pipework fittings, couplings and pump impellers. Amazon Filters is the first company to apply this technology to stainless steel housings. It is more suitable than nickel alloys for a range of chemicals including:

  • Hydrogen iodidetantaline image
  • Hydrogen sulphide

and various acids including:

  • Hydrochloric acid
  • Sulphuric acid
  • Nitric acid
  • Phosphoric acid
  • Formic acid
  • Acetic acid

Unlike coating technology the deposition process produces a surface that does not suffer from separation, peeling or flaking. The Tantaline alloy deposition is approximately 50μm deep and typically a depth of only 10μm is needed for protection, therefore significant safety margin is built into the design. The Tantalum used in the processing conforms with ASTM B364-96. A certificate of conformity and raw material certificates are available on request.
