Abstract: Plant Piping Cathodic Protection in a Congested Environment
Designing a plant piping cathodic protection system to protect buried plant piping systems is one of the more difficult challenges facing any cathodic protection engineer/designer. There are numerous issues that impact the design, constructability, operation and maintenance of cathodic protection systems installed in a plant environment:
- Congested underground environment with numerous other metallic structures
- The likely presence of a pervasive plant earthing/grounding system
- complex construction environments
- Limited available space aboveground
Historically, deep anode ground beds and shallow distributed discrete anodes systems have typically been used in buried plant piping cathodic protection systems.
Impressed Current Plant Piping Cathodic Protection Systems
Over the past decade, the use of impressed current linear anodes to protect plant piping in this challenging application is growing in popularity with CP designers. This is because it offers a unique combination of design certainty and ease of installation in a cost effective manner.
This paper discusses the advantages with the use of linear anodes for cathodic protection of complex plant piping and cathodic protection of tank bottoms from soil side corrosion.
This paper will be presented by Glenn Shreffler, MATCOR Sr. VP Engineering, at the NACE Eastern Area Conference 2016.
