Rotating Cage Apparatus

Overview

Evaluation of corrosion inhibitors for use in refinery and oilfield applications typically requires apparatus that can simulate the interaction between the corrosive fluid and the carbon/low alloy steel used in the construction of the refinery, pipeline, or drilling equipment. ASTM G170 describes the use of a rotating cage (RC) for such testing.

Description

For Evaluation of Corrosion Inhibitors per ASTM G170 and Other Methods

Reactor system made of Alloy C276 or other corrosion resistant alloy, with included rotating cage
Gas feed system to deliver CO2, H2S, or N2
Liquid feed system to deliver acid or inhibitor
Reflux condenser and pressure controller
Automated or manual control and data logging system

Pressure and temperature ratings, reactor volume, material of construction, number of gas and liquid feeds, and control system specifics can be customized to meet individual testing requirements.
