Example Observation of CorrodedCopperPipe Microfocus X-ray CT System

User Benefits

- The three-dimensional shape of the inner surface of the copper tube, which is difficult to observe from the outside, can be visualized in a simple manner. - Microfocus X-ray CT system enables the observation of corrosion progress of a copper pipe on the same specimen because the test is non-destructive.

Introduction

Copper pipes are used for air conditioner refrigerant piping and water supply piping because of their high processability and corrosion resistance. However, copper pipes may corrode depending on the usage environment. It is important to study corrosion progress in a various environments to use the copper pipe safely for a long time. A microfocus X-ray CT system is a useful tool to observe the corrosion of copper pipes. The X-ray CT system makes it possible to visualize the three-dimensional structure without destroying objects, including a copper pipe. In addition, it is possible to examine the progress of corrosion on the same test specimen because it is without losing the corroded part or changing the shape in the observation. Herein, an example of an observation of a copper pipe corroded with aqueous formic acid solution using a Shimadzu inspeXio SMX-225 CT FPD HR Plus micro focus X-ray CT system is described.
