Corrosion Engineering

Written by on .

Definition: Corrosion engineering covers the holistic planning, assessment and optimisation of corrosion-relevant aspects in technical installations and products. It integrates material selection, protection concepts, operating parameters and inspection strategies. The aim is to sustainably ensure integrity and cost-effectiveness.

Practical relevance: The basis is knowledge of corrosion mechanisms, media conditions, temperature and pressure ranges as well as normative requirements (e.g. DIN EN ISO 8044, API 571). Measures include suitable material selection, coating systems, cathodic protection, water chemistry control and Risk-Based Inspection (RBI). A lack of systematic planning leads to increased maintenance costs and failure risks.

Decision-making perspectives:

  • Technical decision-makers: Development of integrative corrosion protection strategies across the entire life cycle.
  • Purchasing/project management: Definition of clear material and protection requirements in specifications.
  • Science: Modelling of corrosion rates and assessment of new protection technologies.
  • Insurance/law: Demonstration of systematic risk assessment and compliance with technical codes and standards.

Typical testing or verification methods: Corrosion testing, electrochemical analyses, wall thickness measurement (UT), RBI analyses, materials analytics.

FAQ:

  • What distinguishes corrosion engineering from individual tests?
  • It considers corrosion risks holistically and with a life-cycle orientation rather than as isolated individual tests.
