Steam is typically among the largest line items in a chemical plant's utility bill, and steam traps are the part of the system nobody looks at until something is visibly wrong. A failed-open trap blows live steam to condensate continuously; a failed-closed trap waterlogs the equipment it serves. Both are invisible on a P&ID and obvious on a bill.
Failed traps are a recurring, compounding loss
Trap populations degrade continuously. Without a survey programme, the failed fraction climbs year on year, and the loss compounds because nobody is measuring it. A one-time audit finds the current failures; a programme keeps the population honest.
Prioritise by loss, not by count
Not every failed trap is worth fixing this quarter. A large trap on a high-pressure header blowing through is worth more than a dozen small failures on a low-pressure line. The audit's job is to rank the replacement list by recoverable steam, so the plant fixes the expensive failures first and sees the saving on the next bill.
Because the loss is quantifiable and the fix is cheap, a steam trap audit is one of the clearest payback cases in plant utilities — and a sensible first Diagnostic Study for a plant that wants to see how we work before committing to a larger programme.
