Why Should Pressure Vessels Be Inspected & Maintained Regularly?


Routine maintenance as well as inspection are vital requirements of engineering, and no alternative can be a worthy substitute to them. Even equipment pieces which are tagged as maintenance-free are prone to damage because of general wear and tear. In order for expensive and high-utility gear to provide continued service, effective and regular inspection combined with proper upkeep is a must.

Nowadays, a majority of equipment used in different fields of engineering are defined by extremely toxic attributes. And in this context, pressure vessels deserve a special mention. To begin with, these units are filled with pressurised gases and toxic chemicals. The force inside them is so powerful that it alters the state of the fluids to a certain extent. For instance, gases turn into liquids first, and again get transformed into gases upon being placed in a cycle of condensation. In other words, it works in almost the same way as a freezing mechanism, but like one scaled for handling a stream of liquid nitrogen that has been processed cryonically.

In case a mishap was to occur, especially one involving deterioration or leaking of the pressurised vessels, that caused the contents of the units to escape, it would inflict great damage by allowing flammable substances to form dangerous clouds of toxic fumes. Fortunately, this kind of leak-out accidents are entirely avoidable – through a well-planned inspection and assessment strategy.

According to the mandatory guidelines of AS/NZS 3788, a typical AICIP pressure vessel inspection analyses a unit within an installation so as to check its operational viability. To put it simply, spotting a worn out seal or a damaged fastener, and then recording it for someone else to resolve, is not enough. There has to be a properly structured maintenance plan for impeding safety issues through replacement of potential weak points on time. Whatever the problem is, general wear and tear or inconspicuous, replacing or resolving it punctually is quintessential.

So if your engineering premises make use of pressure vessels, make sure you have the gears checked on a regular basis by licensed and certified inspectors. There are many organisations in Melbourne who offer welding inspection as well as non destructive testing services. All you need to do is choose a reliable and experienced business from among them and allow the pros to handle the maintenance duties of your pressure vessels.
