Corrosion Materials Selector Skill

Corrosion Materials Selector Skill

Purpose

The Corrosion Materials Selector Skill recommends materials of construction based on process conditions, corrosion mechanisms, and industry standards to ensure equipment reliability.

Capabilities

• Corrosion mechanism identification
• Material screening
• Corrosion rate estimation
• Corrosion allowance calculation
• Material specification development
• Isocorrosion curve analysis
• Galvanic compatibility assessment
• Stress corrosion cracking evaluation
• Cost-benefit analysis

Usage Guidelines
