Downstream refineries and upstream processing facilities operate some of the most aggressive process environments in industry. Sour service circuits, high-temperature reactors, and thousands of pressure-containing assets create an integrity challenge that demands quantitative, risk-ranked inspection planning — not calendar-based intervals.
Reliatic ships with a pre-loaded damage mechanism library for Energy & Refining. Each mechanism is linked to its relevant inspection techniques, examination intervals, and regulatory acceptance criteria.
Irreversible degradation of carbon and low-alloy steels above the Nelson curve boundary, causing fissuring and decarburization in reactor and hot-wall equipment.
Hydrogen-induced cracking and stress-oriented hydrogen-induced cracking in wet H2S environments, particularly at welds and heat-affected zones.
Hidden external corrosion beneath thermal insulation on carbon steel piping operating between -4°C and 175°C, often undetected until wall loss is critical.
High-temperature corrosion in crude distillation units processing high-TAN crudes, accelerating above 220°C with velocities creating turbulent flow.
Environmentally assisted cracking in austenitic stainless steels exposed to chlorides, polythionic acids, or caustic solutions under tensile stress.
Outcome
Reduce unplanned shutdowns by focusing inspection resources on the highest-consequence circuits, with full API 580/581 compliance evidence generated automatically.
