Pipeline Corrosion Management

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 carbon-steel 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 due-diligence for existing structures

• This document does not address threats other than corrosion, such as third-party damage and outside forces

Pipeline Corrosion Management

1. Identify threats

2. Evaluate risk

3. Determine and implement necessary mitigation

4. Monitor effectiveness of mitigation

5. Inspect and assess integrity

6. Remediate

7. Evaluate effectiveness of process

8. Repeat

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

Sales Pitch

• NACE needs your help for developing 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.

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.

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

Top Ten Myths about 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

Top Ten Myths about 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.

Top Ten Myths about NACE Technical Standards

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.
