Thickness Monitoring (TM) Workflow

The following workflow provides the basic, high-level steps for using TM. The steps and links in this workflow do not reference every possible procedure.

Determine the assets in your plant that need to be monitored for corrosion.
Create corrosion analysis settings for each asset.
For each asset that will be monitored, identify one or more Thickness Measurement Locations (TMLs) that will be contained in a TML Group.
After you have identified the TMLs, record Thickness Measurement readings for each TML. These readings can be recorded via data entry or datalogger.
After you record measurements for the TMLs, calculations are made based on those measurements. TM allows you to select different inspection types for your analyses, as well as use multiple types of analyses at once. Using the measurement data, TM can calculate the corrosion rate, the Next Inspection Date, and the Remaining Life for equipment. The calculations can help determine when to repair or replace the asset.

In addition to facilitating the basic analysis workflow described above, TM also provides other tools and features that help you manage your corrosion data and monitor your asset, including:

The Minimum Thickness (T-Min) Calculator, which is designed to calculate the minimum thickness for certain types of components. The T-Min value is used to determine the corrosion rate, remaining life, and next inspection date for the component. The T-Min Calculator is available for piping, pressure vessels, and tanks, and is compliant with ANSI B31 (for piping), API 653 (for tanks), and ASME Section VIII DIV 1 and NBIC NB23, API 510 (for pressure vessels).
An interface for handheld data recorders (dataloggers) manufactured by Olympus and GE. This allows measurement readings that have been recorded in the field to be uploaded automatically to TM. Additionally, data stored in the application can be downloaded to handheld devices.
