Storage Tanks – Corrosion Testing

Storage tanks can be susceptible to a high level of corrosion both from their contents and from the outside environment. Typical storage tank testing applications are:

  • Fuel depot tanks
  • Commercial and domestic LPG tanks
  • Propane gas cylinders
  • Air cylinders for divers
  • Water storage tanks
  • Effluent tanks
  • Pressure vessels.

Using the Multiple-Echo technique which is available on all Cygnus thickness gauges, readings on tanks can be taken ignoring coatings and corrosion, providing a reading of just the remaining metal thickness.

If the survey is being conducted using rope access then the Cygnus 2 PLUS is ideal.

If the atmosphere is potentially explosive using a Cygnus 1 Ex gauge means there is no need for a hot work permit.

The Cygnus 6 PLUS offers the ability to input templates, perfect for taking logging measurements on symmetrical storage tanks. This helps to ensure thickness readings are taken in a methodical manner, with the data is easily transferred to a computer or spreadsheet for reporting.
