Corrosion Management
• Other corrosion management efforts
– Pipeline Corrosion Management standard
– Reinforced concrete structures
– Bridges
– Tanks
– Well casings
– Distribution pipelines
– Oil and gas gathering pipelines
– Water/waste water
What is Corrosion Management
• Definition: A comprehensive program for
reducing the effects of corrosion to an
acceptable level
• NACE Mission Statement: Protecting
people, assets and the environment from
the effects of corrosion
What is Corrosion Management
• Corrosion management is an umbrella
document that ties together all of the
various corrosion activities
– Coatings & surface preparation
– Cathodic protection monitoring and mitigation
– Materials selection
– Internal corrosion monitoring and mitigation
– SCC monitoring and mitigation
– Pipeline integrity assessment
Corrosion Management Process
• The Pipeline Corrosion Management
process provides a common methodology
for reducing the risks caused by corrosion.
• The process continually improves the
prevention and mitigation safeguards
against corrosion failure
• In addition, the process provides an
effective and economical approach to
corrosion mitigation, assessment, and
remediation

Corrosion Management
• Corrosion management includes:
– Design
– Construction
– Operation
– Maintenance
– Remediation
– Assessment
Pipeline Corrosion Management
• This standard applies to onshore carbonsteel pipelines carrying natural gas and
hazardous liquids.
• This standard addresses the three
corrosion (time-dependent) threats
identified in ASME B31.8S and API 1160:
– external corrosion;
– internal corrosion; and,
– stress-corrosion cracking (SCC).
Pipeline Corrosion Management
• The process begins in the design phase
for new construction
• The process entails a comprehensive duediligence for existing structures
• This document does not address threats
other than corrosion, such as third-party
damage and outside forces

Corrosion Management
• Corrosion management documents will
provide comprehensive processes for
managing corrosion in a diverse set of
industries
• Acceptance and implementation of these
documents will improve public safety and
protect assets and the environment,
furthering NACE International’s mission

technical standards
Top Ten Myths about
NACE Technical Standards
10. It takes too much time to attend all
those meetings
Most committees meet once or twice a
year, at conference and/or at Corrosion
Technology week. You don’t have to
attend every meeting to contribute. There
are many ways to participate.

NACE Technical Standards
9. I’m not an expert in corrosion
You don’t have to be a PhD, you just have
to have knowledge that’s worth sharing in
a publication, standard or test method or
at a technical information exchange
meeting. There are opportunities for
participation at any technical level.
Top Ten Myths about
NACE Technical Standards
8. There are already too many people
participating in committees
A recent study shows that only 10% of
NACE members participate in technical
standards development. There are many
opportunities for participation.
Top Ten Myths about
NACE Technical Standards
7. I can’t afford to participate
NACE Corrosion Technology registration
is free to members for early registration. If
you can’t travel to conference or to CTW,
you can still participate by joining STGs
and voting and commenting on standards.
Top Ten Myths about
NACE Technical Standards
6. I don’t like to argue
Well … maybe committees aren’t for you.
Seriously, there are many ways to
contribute that don’t involve committee
meetings:
– RPC reviewers
– Symposia reviewers
– Voting and commenting

NACE Technical Standards
5.
I don’t know how to get involved
– Contact me, I would be glad to help.
– Contact NACE
– Visit the NACE website
– Visit the TCC booth and TCC reception at
conference
– Visit the NACE office at conference and
CTW
Top Ten Myths about
NACE Technical Standards
4. Why should I or my company share my
knowledge with others?
– You and your company benefit from being
knowledgeable
– Stay on top of state-of-the-art technologies and
emerging trends, and speedy access to information
– Network with experts and colleagues, and develop
contacts for identifying best industry practices
– Impact standards that affect industry, and company
products and services
– Develop leadership skills
– Create connections for jobs/career advancement

NACE Technical Standards
3. I am involved in _______, and there
aren’t any standards related to that.
Maybe there should be, and they’re just
waiting for someone like you to get it
started.

2. Local sections are not represented in
technical committee work
TCC Chair is Tom Weber
TCC Vice-Chair is Drew Hevle
Top Ten Myths about
NACE Technical Standards
1. I’m not as good-looking as Tom and
Drew, can I still participate in NACE
Technical Committee work
Trust me, you’re good.
