Rotating cage setup

The rotating cage setup is one of the leading laboratory test methods for determining corrosion inhibitors behavior. Several coupons are placed on a stirring rod on this device between two fixed-distance PTFE holders. In other Words, this system is used to test the behavior of corrosion inhibitors in high-speed fluid and oil-containing pipes.The device is designed with respect to the ASTM G184 standard.

This method is an inexpensive way to assess the corrosion rate and corrosion behavior of inhibitors with the least need for continuous monitoring of the operator. Corrosion Probe Company designs and produces this device based on the ASTM G184 standard. The rotating cage setup is capable of testing 8 samples simultaneously with dimensions of 19×75 mm and with a thickness of 3 mm.
