Frequently Asked Questions

What is the life expectancy of a stainless steel tank?

A properly maintained stainless steel tank can last 30 to 50 years or more, depending on the stored substance, operating conditions, and maintenance practices. Stainless steel offers excellent corrosion resistance, particularly for water and certain chemicals. However, exposure to chlorides, aggressive chemicals, or high temperatures can accelerate pitting and stress corrosion cracking. Regular ultrasonic thickness testing and interior inspections help identify early signs of degradation, allowing for timely protective lining application or repair to extend service life well beyond typical expectations.
