Steam trap failures are the most common source of undetected energy loss in thermal power plants, refineries, and industrial steam systems — and they're almost entirely invisible without a structured survey program. A single failed-open steam trap can waste 10,000–50,000 lbs of steam per year. A plant with 2,000 traps and a typical failure rate of 15–25% can be wasting steam equivalent to 8–12% of total steam production with no visible alarm, no obvious symptom, and no maintenance ticket ever opened. One power plant using OxMaint to manage weekly ultrasonic steam trap surveys and route CMMS-triggered corrective work orders saved $1.2 million annually — not from a major capital project, but from finally knowing which traps were failed, and fixing them on schedule. Here's exactly how that program worked. Start your free trial — launch your steam trap survey program today.

$1.2M Saved Annually From a CMMS-Managed Steam Trap Survey Program.
A thermal power plant replaced its annual walk-and-check steam trap inspection with weekly ultrasonic surveys routed and tracked in OxMaint — and discovered it had been losing the equivalent of $1.2M in steam annually to failed traps nobody knew about.

The Steam Loss Math
What Failed Steam Traps Actually Cost
Before getting to the program, it's worth understanding why steam trap failures are so expensive — and why they're so commonly missed until a structured survey uncovers them.

Before OxMaint
The Program That Was Losing $1.2M/Year
01
Annual Survey, Not Weekly
The plant surveyed steam traps once per year during planned outages. Failed traps discovered in month 2 of the year operated in a failed state for 10 more months before the next inspection — at $240+ per trap per year.
02
No Corrective Work Order Integration
Survey findings were recorded in spreadsheets, then emailed to the maintenance team. Failed trap repairs often took months to schedule — if they were tracked at all. Findings fell through the gap between survey and action.
03
No Failure Rate Trending
Without digitized survey records, the plant had no visibility into which areas had highest failure density, which trap types failed most frequently, or whether the failure rate was improving or worsening year over year.
04
No Energy Loss Quantification
Maintenance teams knew steam traps could fail but had no system to calculate what those failures were costing. Without a dollar value attached to each failure, steam trap repair was always deprioritized against more visible maintenance work.
The OxMaint Solution
How the Survey Program Was Built and What It Changed
The shift from annual to weekly surveys wasn't a staffing increase — it was a routing and record-keeping transformation. OxMaint made the program operationally viable by eliminating the friction of manual survey tracking. See how to set this up — book a 30-minute demo.
Week 1–2
Asset Registry — All 2,000 Traps Mapped
Every steam trap registered in OxMaint with tag number, location, trap type, steam pressure, and criticality rating. Survey routes auto-generated by zone — technicians receive an ordered route each week, not an unstructured checklist.
Week 3
First Full Survey — 23% Failure Rate Discovered
First complete ultrasonic survey found 460 failed traps — 23% of the total population. For each failed trap, OxMaint auto-generated a corrective work order with trap ID, failure mode, estimated steam loss, and repair priority based on steam pressure and system criticality.
Weeks 4–10
Corrective Work Order Execution — Tracked in CMMS
Repair crews worked through the corrective backlog using OxMaint work orders — each recording parts used, time spent, and verified post-repair trap condition. Mean corrective completion time: 8 weeks from discovery to verified repair.
Ongoing
Weekly Surveys — Failure Rate Dropped to Under 3%
With continuous weekly surveys, newly failed traps are detected within 3–5 weeks of failure — before steam loss accumulates significantly. The failure rate stabilized below 3% within 6 months, sustaining the $1.2M in annual savings.

How Much Is Your Steam Trap Failure Rate Costing Right Now?
Most plants don't know their steam trap failure rate. If yours is above 5%, the annual steam energy loss is almost certainly your highest-ROI maintenance opportunity. OxMaint makes weekly survey programs operationally viable — no extra headcount, just better routing and record-keeping.

Frequently Asked Questions
Steam Trap Survey Programs — What Plants Ask Most
How often should steam traps be surveyed to maintain low failure rates?
Industry best practice for high-pressure steam systems is monthly or weekly surveys depending on system criticality. The case study plant found that weekly surveys held the failure rate below 3% — annual surveys had allowed it to reach 23%. OxMaint makes weekly routing operationally practical without extra staffing.
Set up your survey cadence in a free trial.
What testing method does OxMaint support for steam trap surveys?
OxMaint survey work orders support any inspection method — ultrasonic, infrared thermography, visual, or combined. Technicians log test method, reading values, and condition assessment (operating correctly, failed open, failed closed, flooded) against each trap. The CMMS handles the routing and record-keeping regardless of the testing equipment used.
See survey configuration in a demo.
How does OxMaint calculate the energy loss value for failed steam traps?
OxMaint uses trap type, operating pressure, and steam cost input to calculate estimated steam loss per failed trap. Totals aggregate to an annualized energy cost for all currently known failures — giving program managers a dollar figure to prioritize the repair backlog and justify the survey program to management.
Can OxMaint manage steam trap programs across multiple plant sites?
Yes. Multi-site companies can manage steam trap programs across every plant from a single OxMaint platform — with site-level failure rate dashboards, cross-site benchmarking, and consolidated corrective work order tracking. Portfolio-level reporting replaces weekly emails from each plant team.
Discuss multi-site setup in a demo.
How long does it take to onboard a steam trap program into OxMaint?
A standard steam trap program — asset registry, survey templates, corrective work order routing, and energy loss dashboard — can be configured and launched within one week for most plants. Trap data can be imported from existing spreadsheets or P&IDs using OxMaint's bulk upload tool.
Start Finding the Losses Already in Your Plant
$1.2M in Steam Was Already Lost. The Next $1.2M Doesn't Have to Be.
The savings existed before OxMaint was deployed. They were just invisible — scattered across failed traps that had no detection system and no corrective work order routing. OxMaint makes the invisible visible, the untracked tracked, and the reactive proactive.
