Testing Equipments

With our immense domain expertise, we are offering Flow-accelerated corrosion, or FAC Inspection services, in the Power Industry. By monitoring the traces of alloy content of carbon steel piping and components, this inspection service allows for a better planning of inspection protocol. With the help of FAC inspection, our clients can save their time and expense of unnecessary ultrasonic testing. These services are rendered in standard as well as customized form at industry leading prices that enables us to meet the variegated requirements of our clients.

WHAT IS FAC?

Flow-accelerated corrosion, or FAC, is a well-known source of problems in nuclear and fossil-fuel power plants. FAC is a process in which carbon steel piping & components are degraded in the presence of flowing water or two-phase steam/water with IGW dissolved oxygen. As the water flows through and against the inner walls of the carbon steel piping, the stable surface oxide layer (typically Fe304) is dissolved into the flowing stream,  thinning the walls of piping over time and resulting in catastrophic failures due to rupturing.

FAC is a complex process influenced by a number of variables, however, both laboratory testing and plant experience have shown that the material composition, particularly the chromium content, is the most important variable influencing FAC. In fact, extensive research has shown that at higher levels of trace chromium (above ~ 0.1 %) substitution of chromium atoms for iron atoms occurs in the oxide layer, creating an oxide structure of Fe Cr204, which is much less soluble than the normal magnetite (Fe304) oxide layer present in carbon steel piping - in essence preventing the occurrence of FAC.

As a result, it has become industry convention when inspecting for FAC to closely monitor traces of alloy content, as it is the lack of these elements that allow the FAC to occur. Monitoring of traces of alloy content of carbon steel piping and components allows for much better planning of inspection protocol. If inspected piping is found to contain sufficient chromium content, it can be omitted from future. FAC inspection saves the time and expense of unnecessary ultrasonic testing.
