Air receiver tanks are an essential component in many industries, including manufacturing and construction. But did you know that these tanks require regular inspection and testing to ensure they meet safety standards?

Why Regular Inspections and Maintenance are So Important

Pipework Systems and Safety Regulation (PSSR) is critically important when it comes to compressed air systems. This regulatory process places a legal obligation on the owners of all compressed air receivers, such as tanks and vessels, to ensure they have been tested and inspected regularly and per the requirements of the Health and Safety Executive. The PSSR acts as a safety precaution, ensuring that any faults or issues with the tank can be identified immediately.

Safety risks associated with faults within the compressed air receiver include catastrophic failure due to overpressure or long-term corrosion leading to degradation of the vessel wall thickness. As these risks are so severe, owners of these vessels need to ensure that these are regularly checked to guarantee their integrity. This can be achieved through having their Air Receiver inspected by a Competent Examiner at least once every two years, who will assess its safety performance record. In doing so, this guarantees high levels of safety for both users and other personnel in contact with this system.

Inspection of Compressed Air Tanks

Inspection of compressed air tanks is critical for ensuring the safe and efficient operation of machinery and other processes. Regularly checking the pressure inside a compressed air tank should be part of any maintenance routine. Pressure levels in a tank should always be monitored, to ensure that too much or too little are not causing operating problems. 

While full tanks provide power, they can also put a strain on the system if there is too much pressure and cause equipment failure, while insufficient pressure will reduce production and efficiency.

Compressed air tanks must be inspected regularly to ensure they have no leaks or other damage, as these can cause loss of pressure or introduce impurities into the system if undetected. Damaged internal components such as gaskets or tanks can cause pressure drops, so a thorough inspection should always include a close examination of all parts and seals for signs of wear or leakage. 

All valves should also be examined for corrosion and proper operation as improper operation could lead to the release of stored energy from the tank. As compressed air systems age, it is recommended

Audit Accompanied by an Accredited Body

An audit accompanied by an accredited body is necessary for the optimal safety and operation of compressed pressure tanks. This is because the audit requires all relevant aspects to be reviewed including appointment coordination with the inspectors, draining and cleaning the inside of the pressure tank, provision of a temporary compressor for filling the tank quickly, renewable manhole cover seal, and filling and commissioning of the compressed pressure tank after the inspection has been carried out.

A thorough audit that includes comprehensive checks of all parts and features is essential to ensure that they meet all applicable regulations and standards. The coordinated appointment with an inspector ensures that everything is checked to make sure there are no issues. A proper and safe inspection should include inspection of the cleanliness inside, testing any temporary compressor used for filling the tank quickly, re-sealing any manhole covers during maintenance activities if necessary, as well as making sure that everything has been filled out properly once all inspections have been completed. 

Moreover, these audits provide extra security as when contractors perform tests and inspections on machines or components according to a quality standard set by a third party; this will reveal any issues about them. Ultimately, having an accredited body complete this procedure helps keep employees safe and gives consumers confidence that their products work properly by meeting specific quality standards.

What if a Defect is Found by the Inspector?

The pressure tank should be shut down and drained of any remaining liquids and gases before any defect inspections. All defective components should be replaced, followed by a renewal of the inner coating of the tank, as deemed necessary. Any necessary welding in the tank should also be performed during this process to ensure proper sealing. Lastly, the pressure tank will need to be tested by a recognised body such as TÜV or DEKRA before it is refilled and recommissioned again.

Any inspection and replacement processes must be performed thoroughly to guarantee a properly functioning pressure tank that meets all safety requirements. In addition, regular inspections can help detect potential defects more quickly, allowing prompt action to reduce the risk of accidents due to faulty equipment.

Do New Items for the Plant Require an Inspection Before Being Put into Service?

Yes, it is important to have an inspection on a brand new item of plant before being put into service. 

The type and extent of the inspection or examination depends on what type of product is purchased, such as whether it is pressure-containing equipment. For example, an air receiver or steam boiler requires an inspection based on relevant national standards which apply to the type of equipment. The inspections should ideally be carried out by suitably qualified persons before the item is commissioned and put into service.

Can a Maintenance Company Carry Out the Inspection?

Thorough examinations can be carried out by a maintenance company, though certain requirements must be in place to identify them as competent people and deem them fit to perform such an examination. The person carrying out the examination must have adequate theoretical and practical knowledge of the equipment and should have experience in detecting any defects or weaknesses. 

Additionally, that person’s impartiality needs to remain intact, so that objective decisions can be made without bias. Moreover, it doesn’t necessarily require a third-party external source for this; employees in the organisation may have the expertise to handle the task if they are deemed competent.

Proper planning and compliance with all necessary regulations related should come into effect while carrying out a thorough examination, as proper maintenance should be done regularly to maintain optimal performance of machinery and equipment. 

Considering the importance that these examinations hold in terms of safety management, companies need to make sure everything is done correctly and carefully when deploying people for these tasks.


In conclusion, regular inspections and maintenance may seem like a hassle, but they are essential for keeping your operators safe and parts functioning properly. By investing a little time and money now, you can prevent costly repairs and replacements down the line. Don’t wait until it’s too late—make sure you schedule those inspections and maintenance appointments today!
