This paper focuses on assessing the condition of steel pipe cable sections within concrete vaults, serving as protective covers for conductors transmitting up to 66,000 volts. To prevent internal corrosion and short circuits, these cables are filled with pressurized oil. However, water accumulation during storms frequently submerges the cables in water in the concrete vaults, presenting significant challenges for external corrosion protection. Through condition assessment, it was determined that the coating on the 6-5/8" (16.8 cm) diameter steel carrier pipe remained in satisfactory condition. However, the coating on the 14" (35.56 cm) diameter steel casing exhibited poor condition and no longer provided adequate corrosion protection. This paper investigates the underlying causes of premature coating failure and proposes a recommended coating system considering the elevated temperatures experienced by the pipe cables. The findings contribute to enhancing the durability and effectiveness of coatings for submerged steel pipe cables, addressing the challenges posed by water submersion and ensuring long-term corrosion protection. Also, we discuss the temperature and corrosion monitoring by wireless Sensor.

Corrosion Risk Assessment, Load Considerations and Corrosion Engineering Solutions for Aging Structures That Exhibit Accelerated Corrosion in Corrosive Environments

Product Number: 51323-19543-SG

Author: Mehrooz Zamanzadeh, Clinton Char, George T. Bayer, Peyman Taheri, Anil Kumar Chikkam

Structural engineering analysis is an important part of condition assessment of aging concrete structures. Structural engineers involved in condition assessment, maintaining, and repairing concrete structures need to be informed of the principles and practice of corrosion risks facing aging concrete structures. The approach towards this issue, from a corrosion engineer’s standpoint, is to do an inspection/condition assessment before making any form of judgements or recommendations.

The direct current electrical treatments are applied with the aim of improving corrosion resistance of steel embedded in concrete. It is the impressed current cathodic protection in both widely used modes – preventive or remedial, electrochemical chloride extraction, realkalization of carbonated concrete and electrochemical injection of protective agents. All the treatments are similar to each other in its principle and arrangement.
