Pressure vessel inspection checklist

Pressure vessel inspections are essential for maintaining safety and compliance in industries like manufacturing, construction, and logistics. Our pressure vessel inspection checklist template helps you streamline and standardize your inspection process, ensuring thorough and consistent reporting. Using this template, you can easily document findings, track inspection dates, and confirm if all safety measures are met. This tool is designed to enhance your workflow, making it easier for you and your team to maintain high safety standards and regulatory compliance in your operations.

Overview of the pressure vessel inspection checklist

A pressure vessel inspection checklist is an essential tool for any business or organization that owns or operates pressure vessels. This template helps ensure that all safety and regulatory standards are met when performing a pressure vessel inspection. It also provides a comprehensive list of items to check and verify before and after the inspection. Overall, a regular pressure vessel inspection checklist template prevents failures that can cause costly damage to property, company reputation or loss of life. It is important to comply with applicable industry standards for the inspection of boilers and pressure vessels, which at the same time helps the company comply with applicable health and safety legislation.

Key elements of a pressure vessel inspection checklist

For a comprehensive inspection, our pressure vessel inspection checklist includes several important components. By understanding these, you’ll be better able to structure your inspections effectively:

External inspection: This section covers the inspection of the vessel's exterior. You will document any visible defects on the vessel wall, bolts, nuts, and flange faces. Thorough external checks prevent minor issues from becoming major problems.
Internal inspection: Based on ultrasonic wall thickness data, this section may be necessary if there is evidence of wall thinning or no stamp indicating the original wall thickness. Internal inspections are critical for identifying hidden defects that could compromise safety.
Safety devices: In this section, you’ll check if all safety devices, such as pressure relief valves and rupture disks, are working correctly. Properly functioning safety devices are crucial for preventing accidents and maintaining compliance.
Piping systems: Inspect the connected piping systems for proper expansion provisions, support, alignment, and signs of leakage or corrosion. Well-maintained piping systems ensure the overall integrity and efficiency of the pressure vessel.
Final comments and sign-off: End the inspection by logging down any general observations or additional comments. All findings should be signed off by the responsible inspector.

External

Are external coverings like insulation and corrosion resistant coatings in good condition?

Is there leakage of gas, vapor or liquid?

Do pressure vessel mountings have sufficient allowance for expansion and contraction?

Is the vessel wall free of cracks, deformations or any other defects on vessel connections?

Are bolts or nuts free of corrosion or defects?

Any distortion on accessible flange faces?

Have signs of erosion or dents been found on surfaces of the vessel?

Is the vessel free of distortion?

Is the vessel free of cuts or gouges?

Are the surfaces of shells and heas free of cracks, blisters, bulges or any other signs of deterioration?

Are there any cracks or other defects on welded joints & the adjacent heat affected zones?

Internal

Internal inspection may be required only if the ultrasonic wall thickness data indicate that there is some wall thinning or no stamp indicating original wall thickness of the shell and dished heads. All parts of the vessel should be inspected for corrosion, erosion, hydrogen blistering, deformation, cracking, and laminations. https://www.usbr.gov/power/data/fist/fist2_9/fist2-9.pdf

Do you want to proceed with the internal inspection?

Safety Devices

Please perform the following steps for each safety device

Is the pressure set below the maximum allowable working pressure?

If multiple devices are provided, the difference between set pressure does not exceed that permitted by the original code of construction?

Please verify the nameplate capacity and, if possible, compare to the system capacity requirements

Do identifications on seals match nameplates & any other identification (repair or reset nameplate) on the valve or device?

Is the valve or device sealing properly and not leaking?

Are seals intact and without evidence of tampering

Is connecting bolting tight and all bolts are intact?

Is the valve without deposits or mineral buildup?

There is no evidence of rust or corrosion?

No parts are damaged or misapplied?

Did you ensure that visible drain holes are not clogged with debris or deposits?

Rupture Disks:

Is the information on the rupture disk nameplate compatible with the vessel and safety relief valve?

Are the markings indicating direction of flow correct?

Is the space between rupture disk and safety relief valve supplied with a pressure gage, try cock or tell-tale indicator to indicate signs of leakage through the rupture disk?

Is the valve design not influenced by back pressure from leakage through the valve?

Have the combination rules of the code of construction been applied for rupture disks installed on the valve inlet?

Piping Systems

Is there provision for expansion?

Is there provision for adequate support?

There is no evidence of leakage?
