How Often Do Pressure Vessels Need to Be Inspected?

Pressure vessels are a very important component of an air compressor. Some may even go so far as to call it the most important part of the entire system. When it comes to getting the most out of this important piece of the compressor puzzle, it requires an active commitment to inspection and maintenance, in order for you to get the most out of it. So how often do pressure vessels actually need to be inspected? Let’s dig deeper into this topic, in order for you to schedule this alongside critical routine maintenance as well.



What is a Pressure Vessel?

Pressure vessels are a core component of air compressors, because they provide support to the entire system. When the machine is pushed to its limit, pressure vessels help to account for the additional power needed, which leads to better overall efficiency in the long run. These vessels are essentially closed containers which hold gases (or liquids) at higher pressure than the ambient pressure. Through the process of doing this, it is able to push the machine to perform at optimal capacity, making sure that your business gets the most out of the upfront investment you made into your supply chain.



Why Inspection Matters

Periodical inspection is important to make sure that the pressure vessel is in tip top shape, which is not only a performance consideration, but also a safety one. The right inspector will be able to tell if there is a problem with the vessel, and point out key areas that have to be addressed by the maintenance process. There are specific legal requirements for regular thorough inspections, ranging across a wide range of pressure vessels used in various industries. Most commonly, a pressure vessel that holds over 250 liters capacity (like all of those sold by Capstone Engineering) will have to be inspected regularly without question.





How Often Should Pressure Vessels Be Inspected?

Although regulations may vary depending on the make, model and frequency of use, a rule of thumb for inspection is that the pressure vessel should be thoroughly checked at least every twelve months. Some companies opt for quarterly checks, in order to have greater peace of mind that the compressor unit is in working order, and won’t lead to preventable accidents in the workplace. Depending on where you are located, it’s important to comply with local regulations in terms of inspection and maintenance, and the right supplier will be able to give you the best possible recommendation for how often the process should be completed in your operations.



Replacing Pressure Vessels

After extensive use, an inspection may lead to the realisation that a replacement pressure vessel is required. Rather than investing in an entirely new compressor, the Capstone Engineering team can help you with a replacement CE and ASME certified pressure vessel. These are manufactured by Detroit, and also conform to SANS347 and PER. We sell these in different sizes and operating pressures, and you are unlikely to find a better deal for a high quality product elsewhere.
