Radio Frequency Identification (RFID) Smart Corrosion Coupon

Overview

Main Objective

To develop a novel type of smart corrosion coupons using Radio Frequency Identification (RFID) technology for continuously real-time wireless monitoring of corrosion. This will combine the advantages of RFID technology and the corrosion coupon so that a better corrosion monitoring method can be realized. The central idea in this project is to create smart corrosion coupons, which can emit signals indicating the corrosion status of the monitored points on demand, by embedding passive RFID tags inside layers of support materials, which act like normal corrosion coupon.

Public Abstract

Corrosion is an ongoing major problem across several industries, especially in industries which used pipeline systems extensively. This project proposes to create a novel Radio Frequency Identification (RFID) smart corrosion coupon system as a solution for proper corrosion management systems. The proposed system combines the advantages of the RFID technology and the conventional corrosion coupon. Specifically, the proposed system is: (i) a continuous, real-time monitoring wireless non-contact system that streams constant signals regarding its current corrosion status from which appropriate maintenance decisions can be made; (ii) inexpensive, expendable, and simple to be deployed without interfering with existing onsite activities and is be able to be monitored onsite on a regular basis with simple equipment and training; and (iii) universal, deployable in all ranges of conditions including environmental conditions, operating conditions, geometries, locations and materials. This proposal focuses on Concept exploratory phase of this novel technology. There are three main tasks as follows: Task 1 – RFID smart corrosion coupon design Task 2 – Explore potential applications for areas susceptible to corrosion Task 3 – Design laboratory corrosion testing methodology This research project will help: (i) significantly simplify the current corrosion inspection process; (ii) improve the accuracy and effectiveness of resources (human and equipment) available; and (iii) reduce the likelihood of having incident related to corrosion; therefore boost the overall safety performance of pipeline systems. For these reasons, this project is support the PHMSA's pipeline mission to protect people and the environment from the risks of hazardous materials transportation.

Summary and Conclusions

Final report details the design and proof-of-concept for a RFID smart corrosion coupon system. Results and discussions are provided for effect of various factors (i.e. coupon length and location, temperature, humidity, and reader distance) on the performance of the RFID smart corrosion coupon. Selection of an on/off RFID for the final coupon design is discussed. Corrosion rates and characteristics of metal samples (USN G10200 and G10260), which can be used as the material of the RFID coupon antenna, were analyzed. The data can be used to design a RFID coupon so that specific RFID deactivation time can be achieved relative to the antenna's corrosion characteristics.
