Asset Integrity

A: — that's where people conflate pressure margin with damage rate. The difference matters because sulfide stress cracking and hydrogen-related damage care about environment and metallurgy, not whether you're sitting at 80% MAWP, so time-based risk still climbs.

A: — that's the trap, assuming stainless equals immunity. The difference matters because chlorides plus temperature push 300-series steels straight into cracking territory even when general corrosion rates look fine on paper.

A: — that's where people over-focus on process upsets. The difference matters because external fire adds energy continuously, overwhelming blocked outlet scenarios for vapor systems, and relief hardware has to survive that worst credible load.

A: — that's often misread as a corrosion rate issue. The difference matters because hardness correlates with crack susceptibility under sulfide conditions, and once hydrogen gets in, strength works against you.

A: — that's where labels get sloppy. The difference matters because chemistry and velocity interact here, and treating it as simple erosion or simple corrosion misses why elbows thin so fast in wet gas service.

A: — that's the confusion between statistics and duty of care. The difference matters because even low-frequency events are unacceptable when inventories and escalation potential sit above regulatory thresholds.

A: — that's where control tweaks get overused. The difference matters because foaming is a physical separation problem, and geometry plus residence time beat PID adjustments every time.

A: — that's the miss, assuming insulation only saves energy. The difference matters because that temperature band is perfect for trapped moisture to attack steel aggressively from the outside.

A: — that's where blanket rules fail. The difference matters because localized thinning changes stress distribution, and fitness-for-service methods exist to quantify whether that spot actually governs failure.
