Industrial boilers operating under ASME Section I, Section IV, and National Board standards require traceable inspection records, documented tube condition data, and proof of preventive maintenance on demand. OXmaint is the CMMS built to close the gap between what your boiler tells you and what your auditor needs to see — automatically, on every inspection cycle. Sign in to OXmaint and bring every boiler, every tube bank, and every inspection round into a single compliance-ready system today.
Boiler Maintenance Software
CMMS Built for ASME Compliance, Tube Tracking & Zero Missed Inspections
Automate boiler inspection logs, track every tube's wall thickness history, generate ASME-aligned checklists, and produce audit-ready documentation before your National Board inspector walks through the door.
The Real Problem
Why Boilers Fail Audits — and Shut Down Unexpectedly
Most boiler failures are not mechanical surprises. They are documentation failures, skipped inspection cycles, and tube degradation that was visible for months before it became a rupture. The pattern repeats across power plants, refineries, and manufacturing facilities.
Without structured CMMS support, maintenance teams are assembling audit packages from scattered spreadsheets the night before an inspection — and missing early warning signs that systematic tube tracking would have flagged weeks earlier.
01
No Tube-Level History
Thickness readings and corrosion maps live in spreadsheets disconnected from the boiler asset record. Inspectors cannot trend degradation — they only react to failure.
02
ASME Records Not Audit-Ready
National Board inspectors require dated, signed, sequential records for every pressure part inspection. Manual systems routinely fail to produce this chain-of-custody documentation.
03
PM Schedules Missed in Shutdowns
Without automated work order generation tied to boiler hours or cycles, critical safety valve tests and blowdown sequences are skipped during compressed outage windows.
04
Findings Never Become Work Orders
A technician notes scale buildup on a waterwall tube. It goes into a report nobody reads. Three months later the same tube fails. The inspection happened — the follow-through never did.
OXmaint Capabilities
Every Tool a Boiler Maintenance Team Needs — One Platform
OXmaint is purpose-built for pressure vessel environments where compliance is non-negotiable, tube counts are in the thousands, and documentation must survive a National Board audit on any given day.
Tube Tracking & Wall Loss Trending
Every tube in every bank is a tracked asset. Log UT thickness readings, visual condition ratings, and replacement history at the individual tube level. OXmaint automatically calculates wall loss rate and alerts your team when any tube approaches minimum allowable thickness.
ASME Compliance Checklists & E-Sign
Pre-built inspection templates aligned to ASME Section I, Section IV, and NB-23 requirements. Every checklist generates a timestamped, e-signed, sequential record that satisfies authorized inspector documentation requirements — automatically, at completion.
Hour & Cycle-Based PM Scheduling
Set PM triggers based on operating hours, start-stop cycles, calendar intervals, or boiler load thresholds. OXmaint auto-generates work orders for safety valve testing, blowdown procedures, refractory checks, and all interval-based tasks — before the window closes.
Real-Time Audit Dashboard
See overdue inspections, open findings, expiring certifications, and incomplete PM tasks across every boiler in your fleet on a single live dashboard. Share read-only audit views with National Board inspectors or insurance surveyors instantly — no preparation needed.
Inspection Coverage
Every Critical Boiler Inspection Point — Structured and Tracked
OXmaint structures inspection data across every boiler subsystem so nothing falls through the cracks between outage cycles.
| Subsystem | Key Inspection Points | OXmaint Trigger | Priority |
|---|---|---|---|
| Fireside & Combustion | Refractory condition, burner tip wear, furnace wall visual, flame stability logs | Cycle-based PM work order | High Temp Zone |
| Waterside & Tube Banks | UT wall thickness per tube, scale & pitting ratings, waterwall mapping, economiser deposits | Outage inspection WO + wall loss alert | ASME Critical |
| Pressure Parts & Valves | Safety valve set pressure, steam drum nozzles, blowdown valve condition, gauge calibration | Hour-based safety valve test WO | ASME Critical |
| Controls & Instrumentation | Low-water cutoff testing, flame safeguard checks, feedwater control valve PM, emissions log | Calendar-based PM work order | Safety Systems |
| Structural & External | Casing insulation, expansion joint integrity, support structure, access door seals | Annual outage inspection WO | Outage Item |

"
We operate fourteen fire-tube boilers across three plants. Before OXmaint, every National Board inspection became a two-week documentation scramble. Since implementing OXmaint tube tracking and ASME checklists, our last inspection was completed with a same-day documentation package. The inspector said it was the cleanest boiler records he had reviewed in twenty years. We caught two tubes trending toward minimum wall that we would have missed entirely without the thickness trend charts. One of those was in a superheater bank — it would have been a rupture during the next startup.

Common Questions
Boiler Maintenance Software — FAQs
What ASME boiler standards does OXmaint support compliance tracking for?
OXmaint supports inspection documentation and checklist workflows aligned to ASME Boiler and Pressure Vessel Code Section I (Power Boilers), Section IV (Heating Boilers), and National Board Inspection Code NB-23. Checklist templates cover required inspection items for internal, external, and operational inspections. The system captures all required fields — inspector qualifications, inspection date, pressure test results, and findings — in the format National Board Authorized Inspectors require. Sign in to OXmaint to access pre-built ASME inspection templates.
How does OXmaint handle individual tube tracking on large industrial boilers?
OXmaint allows you to create an asset hierarchy where each tube bank is a sub-asset of the boiler, and individual tubes are tracked as discrete inspection points. Each tube stores UT thickness readings over time, visual condition ratings, corrosion type classifications, and replacement records. OXmaint automatically calculates wall loss rate and projects remaining service life — alerting your team when a tube approaches minimum allowable thickness defined by the original ASME design specification.
Can OXmaint trigger boiler PM schedules based on operating hours rather than just calendar dates?
Yes. OXmaint supports multiple PM trigger types: calendar intervals, operating hour thresholds, start-stop cycle counts, and boiler load milestones. You can connect boiler operating data via API with your DCS or SCADA system, or enter meter readings manually on the mobile app. When any trigger threshold is reached, OXmaint automatically generates the work order with the checklist pre-attached and notifies the assigned technician. This is particularly critical for safety valve testing intervals, which in many jurisdictions are defined by operational hours rather than calendar time.
Does OXmaint work for both fire-tube and water-tube boilers?
Yes. OXmaint's asset structure and inspection templates are fully configuration-based. Fire-tube boilers — including scotch marine, locomotive, and vertical designs — have different inspection points than water-tube boilers, HRSGs, or coil-type steam generators. OXmaint lets you build custom inspection checklists and tube mapping structures appropriate to each boiler type in your fleet, so the same platform manages all your pressure vessel assets without forcing a generic template onto fundamentally different equipment.
How quickly can a maintenance team go live with OXmaint for boiler compliance?
Most facilities are running live boiler inspection workflows in OXmaint within three to five business days. The onboarding process covers asset setup, checklist configuration, and mobile app training. OXmaint's onboarding team works with your maintenance manager to configure PM schedules and work order routing during the first week. Book a demo to see the onboarding process and get a timeline specific to your fleet size.
Your Next Boiler Inspection Should Be Your Easiest One Yet
Every tube reading, every safety valve test, every PM completion — documented automatically, archived permanently, and ready for your National Board inspector before they ask.
