Corrosion protection strategies safeguard pressure vessels, piping systems, and process equipment from degradation caused by chemical attack, environmental exposure, and operational stresses. Effective corrosion management extends equipment life, maintains safety margins, and prevents costly failures and downtime.

Protection approaches include material selection (corrosion-resistant alloys, stainless steels), barrier coatings (organic and inorganic), cathodic protection systems, and corrosion allowances in design. Selection depends on service conditions: chemical composition, temperature, pressure, flow characteristics, and environmental factors.

For fabricators, corrosion protection involves proper surface preparation, coating application procedures, weld overlay techniques for cladding, and quality control to ensure protection system integrity. Understanding corrosion mechanisms—uniform attack, pitting, crevice corrosion, stress corrosion cracking—guides appropriate protection strategies.
