Corrosion testing has been regarded for many years as a confusing, time-consuming art, due to the abundance of relevant data, including contradictory reports, which manufacturers had to sift through when selecting suitable materials for measuring devices. Often, irrelevant materials were combined with specific process media and temperatures.
This has prompted instrumentation specialist Endress+Hauser to create a database with relevant, easy-to-use corrosion information and guidelines. The Corrosion Database Applicator Release 8.03 is the first publicly available corrosion database/applicator and allows users to assess which Endress+Hauser flowmeter would be most suitable for a specific application, based on the verification of materials against the background of parameters such as the process medium involved.
The reaction of more than 300 different fluids on the wide variety of materials used in the production of flowmeters have been integrated into the Corrosion Database Applicator, along with relevant information acquired by Endress+Hauser Flowtec AG through years of flowmeter production. Listed materials have been categorised into three classes according to predefined material corrosion rates, with Class A being recommended for top-end applications where continuous and uninterrupted operation is required, as this class denotes a corrosion rate of only 0,005 mm a year.
In order to accurately classify the corrosion rate of a particular application, the Applicator may be used to read the limit temperatures of the respective corrosion classes. Results of corrosion tests are automatically saved along with other design results, which could also be printed.
The corrosion database is, in addition to the basic version of the Applicator, an add-on module requiring a CD-key code during installation. Once installed, the database can be updated via the Internet or with the help of a CD.
