Pressure Vessel Inspection Report Template Free Download
- Template purpose: document vessel identity, service, MAWP, relief devices, corrosion, NDE, thickness readings, repairs, photos, and return-to-service status.
- Core threshold: OSHA describes pressure vessels as tanks or vessels designed to operate above 15 psig, with leakage and rupture hazards that can cause poisoning, suffocation, fire, or explosion.
- Core references: common anchors include 29 CFR 1910.169, ASME BPVC Section VIII, API 510, API 572, API 579-1/ASME FFS-1, API RP 580, and API RP 581.
- Primary risk signal: the CSB reports that the 2017 Loy-Lange pressure vessel explosion killed four people after a vessel weighing about 2,000 pounds launched into the air.
What a pressure vessel inspection report should capture
A pressure vessel report should connect the nameplate, service conditions, inspection scope, damage mechanisms, relief protection, and fitness decision. It should also show whether the inspection was external, internal, on-stream, thickness measurement, repair follow-up, or jurisdictional.
OSHA's pressure vessel overview warns that cracked and damaged vessels can leak or rupture. The report must treat corrosion, wall loss, pressure relief concerns, and altered service conditions as decision points, not background notes.
Standards and report fields
Use the references below to shape the report. Jurisdictional boiler and pressure vessel laws may require state-specific forms, inspector credentials, and filing steps.
| Reference | Inspection relevance | Report field to include |
|---|---|---|
| 29 CFR 1910.169(a)(1) | Air receivers must be constructed to recognized pressure vessel standards | Construction code and nameplate |
| 29 CFR 1910.169(b)(3)(i) | Air receivers must have a drain pipe and valve | Drain condition |
| 29 CFR 1910.169(b)(3)(ii) | Air receivers must have pressure gauges and safety valves | Gauge and safety valve status |
| 29 CFR 1910.101(b) | Compressed gas containers must follow safe handling and use principles | Service and contents |
| 29 CFR 1910.106(b)(1)(v)(b) | Atmospheric and low-pressure tank design references for flammable liquids | Stored material context |
| ASME BPVC Section VIII, Division 1 | Rules for construction of many pressure vessels | Code of construction |
| ASME BPVC Section IX | Welding and brazing qualifications | Repair welding record |
| API 510, Section 6 | Inspection and examination practices for in-service pressure vessels | Inspection scope |
| API 510, Section 7 | Thickness evaluation and corrosion rate considerations | Thickness grid |
| API 572 | Inspection practices for pressure vessels | Damage mechanism notes |
| API 576 | Inspection of pressure-relieving devices | Relief device record |
| API 579-1/ASME FFS-1 | Fitness-for-service assessment | FFS decision |
| API RP 580 | Risk-based inspection principles | RBI basis |
| API RP 581 | Risk-based inspection methodology | Risk ranking |
Identification fields
Record vessel tag, serial number, location, owner, contents, MAWP, design temperature, operating pressure, operating temperature, construction code, year built, and jurisdiction number. Add previous inspection date and next due date.
Include attached equipment such as relief valves, rupture discs, level instruments, pressure gauges, drains, supports, insulation, platforms, and connected piping. A pressure vessel report without relief device data is incomplete for most practical uses.
Inspection scope and evidence
External inspection: note coating condition, insulation damage, supports, anchor bolts, corrosion, leaks, bulging, vibration, settlement, and nozzle condition. Add photos and a component location reference.
Internal inspection: document cleaning status, entry controls, internal corrosion, pitting, cracking, lining, welds, baffles, trays, and shell-to-head transitions. If confined space entry is involved, keep the entry permit or reference number in the report.
Thickness readings: include corrosion monitoring locations, nominal thickness, previous thickness, current reading, corrosion rate, retirement thickness, and next inspection recommendation. Keep the measurement device and technician identified.
Statistics to include in a safety brief
The U.S. Chemical Safety and Hazard Investigation Board reports that the Loy-Lange Box Company pressure vessel explosion killed one worker and three members of the public in 2017. CSB states that the failed vessel weighed about 2,000 pounds and traveled several hundred feet.
OSHA describes pressure vessels as equipment generally designed to operate above 15 psig. That threshold helps explain why a small line item, such as missing thickness data or a relief valve mismatch, can become a high-consequence finding.
Corrective action fields
Use Immediate control, Engineering review required, Repair plan, NDE required, Relief device action, Pressure test required, and Return-to-service approval fields. Mark any uncertainty that requires an authorized inspector, engineer, or jurisdictional review.
Do not let the template imply that a generic inspection can rerate a vessel. Rerating and fitness decisions should follow the applicable code, owner-user program, inspector qualifications, and jurisdictional requirements.
SERP gap statement
Most pressure vessel template pages list generic inspection items but skip thickness data, relief device traceability, and fitness-for-service decisions. This guide ties report fields to OSHA pressure vessel rules, ASME BPVC construction references, and API in-service inspection practices.
How InspectionReport.app fits the workflow
InspectionReport.app supports AI-assisted photo-to-report drafting. Upload inspection photos, add details, let AI draft the report, review the draft, and export a PDF or Word file.
Use it for photo-backed observations such as corrosion, damaged insulation, nameplates, pressure gauges, relief devices, supports, leaks, and repair evidence. The app does not supply custom checklists, offline mode, GPS, signatures, or photo capture inside the app.
FAQ
What should be in a pressure vessel inspection report?
Include vessel identification, nameplate data, service, MAWP, relief devices, inspection scope, photos, damage mechanisms, thickness readings, recommendations, and return-to-service status. Add jurisdictional fields where required.
Which standard governs pressure vessel inspection?
In-service process vessels commonly reference API 510, with inspection practices supported by API 572 and relief device guidance from API 576. Construction code references often include ASME BPVC Section VIII.
Does OSHA have a pressure vessel standard?
Yes, OSHA has specific pressure-vessel-related standards such as 29 CFR 1910.169 for air receivers. OSHA also identifies pressure vessel hazards through compressed gas, flammable liquid, maritime, and construction standards.
Can a template determine if a pressure vessel is fit for service?
No. A template can organize evidence, but fitness-for-service decisions require qualified evaluation under references such as API 579-1/ASME FFS-1, owner procedures, and jurisdictional requirements.
