Storage Tank Inspection (API 653) Services

At Asset Conformity Testing Services (ACTS), we deliver API 653-compliant storage tank inspection services to help industries ensure the safety, reliability, and regulatory compliance of aboveground storage tanks (ASTs). Backed by NATA accreditation (ISO/IEC 17020 & 17025), our team of experienced engineers and inspectors provides independent, accurate, and actionable reports that meet statutory and industry requirements.

What is API 653?

API 653 is the industry standard for the inspection, repair, alteration, and commissioning of aboveground storage tanks. It applies to steel tanks built to API 650 or similar standards and ensures tanks are safe for continued operation through regular in-service and out-of-service inspections.

By partnering with ACTS, you ensure your storage tanks are assessed against the highest international safety and compliance standards.

Why Regular Tank Inspections Matter

Storage tanks are critical assets, and failures can lead to environmental hazards, downtime, and costly repairs. API 653 requires inspections at defined intervals:

External visual inspection: Every 5 years or per risk assessment
Internal inspection: Typically every 10 years or per corrosion data
Risk-Based Inspection (RBI): Tailored intervals based on tank service conditions

Regular inspections ensure:

✅ Regulatory compliance with API, AS, and WHS standards
✅ Asset life extension through proactive maintenance
✅ Environmental protection and reduced risk of leaks
✅ Cost savings from early detection of corrosion or defects
