Cathodic protection in hazardous areas discussed

When working in hazardous locations, such as during heatwaves or extreme weather conditions, extra consideration is made to protect materials against corrosion.

This applies for example when working with steel structures, like pipes, tanks and bridges.

This is where the use of cathodic protection (CP) systems becomes crucial.

Corrosion is a natural process where metals are gradually degraded and destroyed by chemical and electrochemical reactions with their environment.

Galvanic and impressed current CP systems are used to control the corrosion of steel in structures and involve voltages and currents being introduced into the structures.

Occasionally, these structures are situated in hazardous environments where there are explosive liquids and gases, creating a risk of an explosion occurring if electrical voltages and currents are not managed carefully.

“It’s clear that using galvanic or impressed current CP systems in hazardous areas needs to be handled carefully,” explained David Celine, Managing Director of Omniflex.

“The approach required to manage this must be well-documented and systematic, detailng all electrical circuits and materials present, to comply with regulations and standards.”
“There are international standards governing the installation and use of electrical equipment in hazardous areas, which all equipment located in hazardous areas must comply with,” said Mr Celine.

Unfortunately, these standards don’t specifically discuss CP systems in hazardous areas.

This perpetuates a lack of understanding within the corrosion industry on how to quantify the dangers presented, and how to mitigate these dangers in accordance with the requirements of the standards.

Mr Celine will be holding a presentation on hazardous areas and address the impacts this has on the design of CP systems referencing real-life examples.

It will be held in the coming Corrosion and Prevention annual event online,of cathodic protection specialists at the Australasian Corrosion and Prevention conference.

The event online is the largest gathering on corrosion and mitigation in the Southern Hemisphere, hosted by Omniflex.

Omniflex designs and manufactures electronic products and systems for the automation and control industry worldwide, specialising in remote monitoring.

This includes industrial networking, remote I/O systems, utilities monitoring, process auto-mation systems, signal conditioning, and alarm and event management.
