Pressure Vessel Inspection Scheduler
A free pressure vessel maintenance register: last service, interval, due date and overdue alerts — sorted by urgency, stored in your browser.
Your register stays in this browser (localStorage) — nothing is uploaded.
Add your first pressure vessel to see the schedule. Sorted by urgency, the next due item is always on top.
Field notes from maintenance practice
Vessel scheduling is corrosion math wearing a calendar: the internal interval comes from measured corrosion rate (half the remaining life to minimum thickness, capped by code), so each vessel's line should carry its last thickness reading and next statutory date. The register keeps the portfolio visible — plants rarely miss the boiler, they miss the air receiver behind the mezzanine and the forgotten ammonia accumulator.
Relief devices carry their own line (test/recertify per service, commonly 1–5 years) — a perfect vessel with a seized relief valve is still a bomb. Run the register on whatever device lives where the work happens — a workshop tablet beats a spreadsheet on someone's laptop, because the person doing the job sees the list.

Pressure vessels are statutory equipment — intervals and inspections must follow your jurisdiction's code and an authorised inspector; this register only tracks the dates.

About Pressure Vessel Inspection Scheduler
This scheduler keeps a living register of your pressure vessels: add each one with its last service date and interval, and the board computes due dates, sorts by urgency and flags anything overdue or due within 14 days. One tap (✓) marks a service done and restarts that asset's clock. Common practice per API 510/NBIC: external inspections at least annually-to-5-yearly and internal/UT examinations at intervals set by half remaining-life or risk-based inspection, with jurisdictional rules deciding the legal minimum.
How to use Pressure Vessel Inspection Scheduler
- 1Add each asset with its last service date and interval — presets reflect the cited standard, and you can override per asset.
- 2The register sorts itself by urgency: overdue first, then due-soon (≤14 days), with a badge per asset.
- 3Tick ✓ when a service is done to reset that asset's clock to today — the whole register persists in your browser.

Frequently asked questions
How often should a pressure vessel be serviced or inspected?+
Common practice per API 510/NBIC: external inspections at least annually-to-5-yearly and internal/UT examinations at intervals set by half remaining-life or risk-based inspection, with jurisdictional rules deciding the legal minimum. Severe duty, harsh environments or regulatory requirements shorten it — and your OEM manual, insurer or local code always takes precedence over the generic default.
How is the internal inspection interval actually calculated?+
From corrosion rate: rate = (previous thickness − current)/years between readings; remaining life = (current − minimum required)/rate; next internal ≤ half the remaining life (API 510 typical, max 10 years). A vessel losing 0.1 mm/yr with 4 mm of corrosion allowance left has 40 years remaining → inspect within 10 (the cap governs). No thickness history means no math — which is why the first UT survey on an undocumented vessel is urgent, not optional.
How strict should I be about hitting the due date exactly?+
Treat the due date as the end of a window, not a cliff: industry practice allows roughly ±10% of the interval for planning convenience. What kills pressure vessels is systematic slippage — each service a few weeks late quietly stretches the real interval far beyond the standard one. The overdue badge exists to make that visible.
How do I handle assets that fail between services?+
Repair work doesn't replace the scheduled service unless it covered the same scope — a breakdown fix usually addresses one fault, while the PM covers the checklist. After a major repair that does cover the scope, tick the pressure vessel as serviced; after a spot fix, leave the schedule untouched.
