In-service ammonia storage tank inspection

For operators responsible for ammonia storage safety, traditional internal inspections create major cost, safety and availability challenges. Decommissioning, cleaning and opening tanks leads to prolonged downtime, exposure risks and oxygen ingress that can initiate stress corrosion cracking (SCC).

In-service ultrasonic inspection of tank welds

In-service automated ultrasonic inspection verifies weld integrity and detects SCC while the tank remains in operation. High-resolution ultrasonic data is collected under actual operating conditions, providing reliable documentation of structural condition, reducing inspection risk and supporting compliance without decommissioning the tank.

Shutdown-based inspections disrupt production

Internal inspections require decommissioning, cleaning and cooling, often resulting in weeks of downtime and significant operational cost.

Oxygen exposure increases SCC risk

Opening ammonia storage tanks introduces oxygen to welds and heat-affected zones, creating conditions that can initiate or accelerate stress corrosion cracking.

Confined-space work compromises safety

Manual weld inspection inside tanks exposes personnel to hazardous environments and increases safety risks during inspection activities.

Manual methods limit data quality and traceability

Conventional inspection techniques provide less consistent coverage and weaker documentation, reducing confidence in defect detection and long-term integrity.
