A: That's the most common mistake — treating this like a chloride problem instead of a cracking problem. Wet H2S with condensation puts you straight into sulfide stress cracking territory per NACE, and 316L drops out on hardness and SSC resistance even if pitting looks manageable on paper. Monel sounds confident, but it's not universally immune once you factor cold work and specific environments. Duplex works here if you actually control hardness and heat input, which the standard assumes you will.

A: That's the most common mistake — assuming a level alarm somehow manages pressure. An HH alarm without an interlock doesn't touch the pressure boundary at all; that's PSV territory. It can warn you before carryover, efficiency loss, or ugly suction conditions, but it doesn't stop a blocked outlet from pushing you past MAWP.

A: That's the most common mistake — mixing up normalized flow with what's actually moving through the pipe. The orifice only sees operating density, not your Nm3/h bookkeeping, and at constant mass flow higher pressure means higher density and higher DP. The trend going up is exactly what you'd expect, even if the acceptance box is still green.

A: That's the most common mistake — jumping straight to simulation and trusting the screen. If you don't prove power and wiring first, a swapped pair can hide behind a smart transmitter behaving nicely on a bench signal. Order matters when you're trying to catch dumb errors before they turn into night-shift surprises.
