Control of the level of contamination in the pipeline is limited, there will always be the scenario of:

• the upstream part failed
• the media should be cleaner than it is
• we don’t have control over the upstream pipework

To determine contamination levels the strainer or filter must be monitored for differential pressures this is the only way of establishing that contamination exists, highlighting the need for inspection. In many cases it is very difficult to determine visually if the internals are contaminated or not which is why Vee Bee set up their Cleaning and Inspection Department. Cleaning and Inspection will inspect the integrity of the internal parts and can also determine the level and type of contamination present, in addition the internal will be put through a specialized form of cleaning which has no detrimental effect on the internal parts and has a very high cleaning efficiency.
