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

When to Use

• Selecting materials for new equipment
• Evaluating corrosion failures
• Assessing process changes
• Specifying replacement materials

Prerequisites

• Process conditions defined
